NHTSA Interpretation File Search

Overview

NHTSA's Chief Counsel interprets the statutes that the agency administers and the standards and regulations that it issues. Members of the public may submit requests for interpretation, and the Chief Counsel will respond with a letter of interpretation. These interpretation letters look at the particular facts presented in the question and explain the agency’s opinion on how the law applies given those facts. These letters of interpretation are guidance documents. They do not have the force and effect of law and are not meant to bind the public in any way. They are intended only to provide information to the public regarding existing requirements under the law or agency policies. 

Understanding NHTSA’s Online Interpretation Files

NHTSA makes its letters of interpretation available to the public on this webpage. 

An interpretation letter represents the opinion of the Chief Counsel based on the facts of individual cases at the time the letter was written. While these letters may be helpful in determining how the agency might answer a question that another person has if that question is similar to a previously considered question, do not assume that a prior interpretation will necessarily apply to your situation.

  • Your facts may be sufficiently different from those presented in prior interpretations, such that the agency's answer to you might be different from the answer in the prior interpretation letter;
  • Your situation may be completely new to the agency and not addressed in an existing interpretation letter;
  • The agency's safety standards or regulations may have changed since the prior interpretation letter was written so that the agency's prior interpretation no longer applies; or
  • Some combination of the above, or other, factors.

Dear Mr. Nagaraj,

This letter responds to your inquiry to the National Highway Traffic Safety Administration (NHTSA) regarding compliance of a new horn function named “Superhorn” with Federal Motor Vehicle Safety Standard (FMVSS) No. 141. Based on the information you provided, as explained in more detail below, we have concluded that Superhorn is permissible under FMVSS No. 141.

Description of the Superhorn

You state that Superhorn is a feature that plays a horn sound through the same system used for emitting the pedestrian alert sound; the vehicle would not be equipped with a traditional horn trumpet. In addition to being user-actuated, you state that Superhorn would resemble a traditional horn both in sound and loudness and would only be played for the duration of continuous horn control actuation (up to a maximum of a 60 seconds before the system times out). You further state that Superhorn is independent of the pedestrian alert system, and that the pedestrian alert system would be emitted alongside the Superhorn sound from the same speaker system. You acknowledge that the pedestrian alert sound may be masked to some extent by the horn when the horn is actuated.

Background

NHTSA established FMVSS No. 141 in 2016, pursuant to the Pedestrian Safety Enhancement Act of 2010 (PSEA).1 The standard sets minimum sound level requirements for hybrid and electric light vehicles operating at low speeds and aims to reduce injuries to pedestrians and other road users by increasing the detectability of hybrid and electric vehicles.

NHTSA does not approve motor vehicles or motor vehicle equipment and does not determine whether a product conforms to the FMVSS outside of an agency compliance proceeding.
Instead, the Safety Act requires manufacturers to self-certify that their products conform to all applicable FMVSS that are in effect on the date of manufacture. NHTSA also investigates safety-related defects.

Discussion

There are three requirements of FMVSS No. 141 pertinent to the analysis of the Superhorn.

Sound performance requirements (S5.1 through S5.4)

S5.1 through S5.4 describe performance characteristics related to measured volume and frequency bands of sounds emitted from covered vehicles. The volume and frequency requirements described in S5.1 through S5.4 are vehicle-level requirements; individual sounds such as horns, including the proposed Superhorn, are not required to independently meet those requirements.2

The performance requirements described in S5.1 through S5.4 are intended to measure the detectability of a vehicle during routine operation. Since the Superhorn is not automatically engaged during routine operation, the Superhorn may not be used to meet FMVSS No. 141’s minimum required sound levels.3

Sameness requirement (S5.5)

S5.5 describes the “Sameness requirement,” which requires all vehicles of the same make, model and trim equipped with a pedestrian alert sound to emit the same set of sounds. NHTSA has previously explained that the Sameness requirement, which stems from the PSEA,4 only applies to sounds added to the vehicle for the purposes of complying with the standard.5 The agency believes that this interpretation is still appropriate. Requiring all sounds produced by non- pedestrian alert systems to be identical would be overly burdensome and would prevent certain optional equipment that could affect the sound of a vehicle from being offered for sale.

Even though the Superhorn would be played through the same speaker system as the pedestrian alert system, according to your description it is not being added to meet volume and frequency requirements of FMVSS No. 141, and it is only active during horn control actuation. Therefore, Superhorn is not subject to the Sameness requirement.

Prohibition on altering the sound of a covered vehicle (S8(b))

S8(b) prohibits providing “any mechanism, equipment, process, or device intended to disable, alter, replace, or modify the sound emitting capability of a vehicle subject to this standard, except in connection with a repair of vehicle malfunction or to remedy a defect or non-compliance.” S8(b) is derived from a similar provision in the PSEA.6 In proposing S8(b), NHTSA described the intention of the provision as “to avoid the situation where vehicle sounds are changed, at the request of the consumer, to something individualized and no longer associated with the specific make/model of motor vehicle, or indeed even recognizable as a motor vehicle at all.”7 NHTSA reaffirmed this position in response to a petition for reconsideration, stating that S8 is intended to prevent access to vehicle features that could modify or adjust the emitted sound or render it noncompliant.8

As a practical matter, NHTSA has not applied S8(b) to other vehicle devices or mechanisms such as traditional horns or audio systems, even though these systems have the potential to alter the sound produced by vehicles and how they are perceived by pedestrians. NHTSA views S8(b) as preserving the integrity of the pedestrian alert system and, more generally, the vehicle’s detectability by pedestrians. Devices that directly touch upon the vehicle alert system, including a vehicle’s pedestrian alert speakers or audio file, receive a higher level of scrutiny. This is not to imply, however, that these are the only systems that may potentially run afoul of S8(b); devices or mechanisms that supersede or replace the pedestrian alert sound may also be found non-compliant.

NHTSA believes that the Superhorn, as it is described in your correspondence, does not conflict with S8(b). From your description, the pedestrian alert would continue to play the same set of sounds unaltered and concurrent with the Superhorn for the duration of horn control actuation. As you noted, the Superhorn has the potential to mask the pedestrian alert, in much the same way as a traditional horn may mask a pedestrian alert. However, the pedestrian alert would be masked with a trumpet sound resembling the tone, pitch, and loudness of a traditional car horn and only while the Superhorn sounds. Trumpet horn sounds are distinctive and recognized as a warning to pedestrians and other road users of an imminent hazard such as a vehicle collision.
The agency does not view masking under these described circumstances as problematic and believes that the proposed Superhorn would not alter the pedestrian alert or impair the detectability or recognition of a covered vehicle within the meaning of S8(b).

NHTSA notes that this interpretation is based on the description of the Superhorn you provided. If the Superhorn’s performance varies in any way materially from the description you provided, this interpretation will no longer be applicable. For example, if the Superhorn played in the absence of continuous horn control actuation, played for a longer duration, played a sound that made vehicles less identifiable as a vehicle, or disabled the pedestrian alert sound, then the feature would likely be deemed a device that alters, disables, or replaces the pedestrian alert in contravention of S8(b) or a pedestrian alert subject to the Sameness requirement in S5.5.

I hope this information is helpful. If you have any further questions, please feel free to contact Paul Connet of my staff at this address or at (202) 366-5547.

 

Sincerely,

 

John Donaldson 
Acting Chief Counsel

 

1 Pub. L. No. 111-373, 141 Stat. 4086 (Jan. 4, 2011).

2 Hybrid and electric vehicles are not required to have a dedicated pedestrian alert sound; vehicles that produce sufficient sound to meet the performance requirements described by S5.1-S5.4 may satisfy the requirements of FMVSS no. 141 without a dedicated alert system. See 81 FR 90416, 90450 (Dec. 14, 2016).
3 FMVSS 141 does not regulate other vehicle sounds besides the pedestrian alert system, but the test procedures do control for them. S7.1.2(a) specifies that measurements containing “any distinct, transient, loud sounds (e.g., chirping birds, overhead planes, trains, car doors being slammed, etc.) are considered invalid.” The same paragraph states that “[m]easurements that contain sounds emitted by any vehicle system that is automatically activated and constantly engaged during the entire 10 second performance test are considered valid.” Similar language conveying the same concepts is used as S7.3.2(a).

TEXT:

Mr. David E. Martin Director Automotive Safety Engineering General Motors Corporation 30400 Mound Road Warren, MI 48090-9015

Thank you for your letter of July 30, 1985, to Administrator Steed concerning the requirements of Standard No. 210, Seat Belt Assembly Anchorages. Your letter was referred to my office for reply. I regret the delay in our response.

You asked the agency to reconsider its interpretation of the requirements of S4.1.1 of the standard which requires the installation of "seat belt anchorages for a Type 2 seat belt assembly" at certain positions in motor vehicles. You specifically asked that we issue a new interpretation that S4.1.1 is satisfied by installation of safety belt anchorages utilized by a safety belt meeting the occupant protection requirements of Standard No. 208, Occupant Crash Protection. You also asked that if a new interpretation could not be issued, then the agency should treat your letter as a petition for rulemaking. As discussed below, the agency believes that the change you seek can only be made by a rulemaking proceeding. Therefore, as you requested, we will treat your letter as a petition for rulemaking, which is granted.

You offered several arguments in support of your view that the existing language of S4.1.1 is satisfied if a passenger car is equipped with anchorages for safety belts meeting the occupant protection requirements of Standard No. 208. You noted that the definition of a Type 2 safety belt assembly set forth in S3 of Standard No. 209, Seat Belt Assemblies, is based solely on the existence of pelvic and upper torso restraints and does not differentiate between manual and automatic belts. You also noted that S4.3(j) of Standard no. 209 applies to Type 1 and Type 2 belts and that the agency has interpreted section S4.3(j) to apply to both automatic and manual safety belts.

You also argued that redundant anchorages would not be used since an owner would not purchase an aftermarket manual belt intended to be anchored in the vehicle "B" pillar, if a door-anchored safety belt were available from the manufacturer. You said this would be particularly true of the door-mounted detachable automatic safety belts General Motors intends to use. In addition, you pointed out that the agency April 1985 proposal to require dynamic testing of manual belts also supports the elimination of the requirement for additional anchorages. You noted that the agency proposed that dynamically-tested manual belts would be exempt from the anchorage location requirements of Standard No. 210. Thus, a manufacturer may have anchorages outside of Standard No. 210 location zones, but the automatic belts attached to the anchorages would meet the occupant protection requirements of Standard No. 205. You said that a manual belt attached to anchorages within Standard No. 201's zone might not meet Standard No. 208's occupant protection requirements.

Finally, you said that the cost impact of providing the additional anchorages is not minimal. You said that "the cost penalty to General Motors customers would be approximately $6,000,000 annually when all vehicles were redesigned assuming that the vehicles were required to incorporate automatic restraints."

While we believe that you have raised a number of important issues concerning the current requirements of Standard No. 210, we believe that given the specific language of S4.1.1, any change to those requirements can only be made through a rulemaking proceeding. Standard No. 210, as currently written, specifically refers to providing anchorages for a Type 2 safety belt. The agency his consistently recognized a distinction between Type 2 belts and automatic belts. That distinction is based on a comparison of the design features of a two point automatic belt with those of a Type 2 lap/shoulder safety belt. Standard No. 209 defines a seat belt assembly as "a strap, webbing, or similar device" used to secure a person in a crash. Under Standard No. 203. a Type 2 seat belt assembly is defined as a strap, webbing or similar device which provides "pelvic and upper torso restraint." Thus, a Type 2 safety belt provides webbing to restrain both the pelvis and upper torso and requires three anchorages to be installed. In contrast, an automatic belt can use webbing to provide upper torso restraint, which would require two anchorages to install, and not have webbing to restrain the pelvis. Instead, a two point automatic belt relies on non-belt technology, such as a knee bolster, to restrain movement of the pelvis.

The agency recognized the design distinctions between Type 2 belts and automatic belts by specifically providing a separate definition of automatic belt in S4.5.3 of Standard No. 208. In addition, the agency recognized a distinction between automatic and Type 2 belts by specifying in Standard No. 208 that an automatic belt may be used "in place of any seat belt assembly otherwise required by" S4 of the standard. The other seat belt assemblies required by 54 are Type 1 and Type 2 systems. To further contrast the distinction between automatic belts and Type 2 belts, S4.5.3.1 of Standard No. 208 specifically provides that "an automatic belt that provides only pelvic restraint may not be uses...to meet the requirements of any option under S4 and in place of any seat belt assembly otherwise required by that option."

Given these distinctions between a Type 2 and an automatic belt, we believe that the reference to a Type 2 belt in S4.1.1 of Standard No. 210 requires us to retain our current interpretation of that provision. However, we do believe you have raised important questions about whether that provision should be changed. We expect to begin rulemaking shortly on this issue.

Sincerely,

Erika Z. Jones Chief Counsel

The Honorable Diane Steed Administrator -- NHTSA

Docket 74-14, Notice 38

Dear Ms. Steed:

General Motors is currently developing new vehicle models which will be introduced concurrent with, or after, the start of the passive restraint phase-in period. This has necessitated a review of NHTSA FMVSS interpretations as they would apply to seat belt restraint systems. It is apparent from that review that several previous NHTSA interpretations do not comprehend current automatic seat belt technology.

Of specific concern to General Motors is NHTSA documentation which suggests that automatic seat belts are experimental and, therefore, not "Type 2" seat belts for the purposes of S4.1.1. of FMVSS 210. Without assurance that the position set forth in these NHTSA documents is no longer considered current by the agency, a manufacturer is faced with the prospect of having to add manual seat belt anchors into a vehicle even though automatic seat belts are to be installed.

1 A NHTSA position that additional manual belt anchors were necessary because of the "experimental" nature of automatic seat belts was first noted in Docket 72-23, Notice 5 (43 FR 53440, dated November 27, 1978) which granted a petition by General Motors to exempt automatic belts from the anchorage location requirements in FMVSS 210. Most recently, the agency in its January 29, 1985 response to a letter from the Daihatsu Motor Company regarding the redundant anchor requirement reiterated that, "The exemption was provided for in the standard to allow manufacturers to experiment with various automatic belt designs."

While NHTSA's position that automatic seat belts are "experimental" was perhaps appropriate in 1978, we believe that a change is warranted in light of design developments and recent regulatory initiatives. Significant field experience has been gained over the last decade with automatic belt designs, e.g. the VW Rabbit and GM Chevette. In addition, FMVSS 208 rulemaking responses suggest that many manufacturers are currently developing such belt systems in anticipation of the passive restraint requirements. Finally, concern for public reaction to automatic seat belts, which is basic to the agency's use of the term "experimental" was discounted by the Department of Transportation (DOT) in its July 17, 1984 final rule (Docket 74-14, Notice 36). Noting that most, if not all manufacturers, would be expected to use detachable automatic seatbelts, DOT stated that, "Detachable belts should alleviate some consumer concerns about automatic belts."

The aforementioned NHTSA letters of interpretation notwithstanding, there is existing regulatory language which General Motors believes supports a position that S4.1.1 of FMVSS 210 is satis-fied if a passenger car is equipped with any belt restraint system meeting the performance requirements of FMVSS 208. Most compelling is the fact that the definition of a "Type 2" belt assembly, as set forth in S3 of FMVSS 209, is based solely on the existence of pelvic and upper torso restraints. The definition does not differentiate between manual and automatic belt systems. Further, S4.3 (j) of FMVSS 209 states that the requirements of that section apply to Type 1 and Type 2 belt systems. This has been interpreted by the agency to include both manual and automatic seat belt systems. (See NHTSA letter of interpretation to Volkswagon, dated August 7, 1981.)

A review of FMVSS 210 regulatory history also supports a position that seat belt performance is neither assured nor necessarily limited by anchor locations. While vehicles equipped with manual belts meeting the existing anchorage location requirements of S4.3.1 of FMVSS 210 have demonstrated excellent performance in the field, this experience should not be interpreted as establishing that other anchorage locations would not have produced equally good results. In fact a parametric study by General Motors, which was provided to NHTSA in 1979 (USG 1763), suggests that specific vehicle interior parameters, such as occupant proximity to steering columns, instrument panel, etc., could have more influence on measured dummy data than some of the restraint parameters. A copy of that study is attached.

While the above discussion deals with the regulatory aspects of S4.1.1 of FMVSS 210, there are additional compelling reasons for a new interpretation of that section. These reasons are based on practical implications as well as recent rulemaking actions that bear on the existing interpretations.

Most importantly, the redundant anchors would very likely never be used. It is highly improbable that a customer would demand an aftermarket manual belt intended to be anchored in the vehicle "B" pillar, if a door anchored belt were available from the manufacturer as a replacement for the OEM automatic seat belt. This would be true whether or not the passive restraint requirements were eventually rescinded. As noted in General Motors' response to Docket 74-14; Notice 36 (USG 2284), automatic seat belt designs would need to be detachable to ensure public acceptability. As a result, a detachable automatic seat belt design would also be usable as a manual seat belt. (See Attachment 6 of USG 22B4). This "convertibility" feature would be expected to further reduce the likelihood of replacement.

The redundant seat belt anchor issue is clouded by NHTSA's recent manual belt dynamic test proposal in Docket 74-14, Notice 38. If enacted, that proposal would provide manual belts with the same exemption from the anchorage location requirements in FMVSS 210 now afforded automatic belts. This would allow manufacturers to find an optimum anchor location for manual belt systems on the basis of best overall performance. With this scenario, the S4.1.1 requirement in FMVSS 210 becomes even more inappropriate in that it may not reflect a belt anchor location needed to meet the FMVSS 208 injury criteria.

General Motors is concerned that cost factors may have been understated and this may have misled NHTSA regarding the need for a review of the current S4.1.1 interpretation. This is suggested by the agency's denial of a 1981 Toyo Kogyo petition (46 FR 54391) wherein it was stated that, ".the cost increase associated with these additional anchorages is minimal at best". The cost penalty to General Motors customers would be approximately $6,000,000 annually when all vehicles were redesigned, assuming that the vehicles were required to incorporate automatic restraints.

In summary, it is General Motors view that the requirements of S4.1.1 in FMVSS 210 would be satisfied by the vehicle seat belt anchors utilized by any belt restraint system that meets the performance requirements of FMVSS 208 and requests that the agency issue an interpretation to that effect. That interpretation would acknowledge that a three-point automatic belt qualifies as a Type 2 belt; therefore, additional anchors would not be required. If such interpretation is not possible, General Motors requests notification of that fact and further requests that this letter be treated as a petition for amendment of S4.1.1 of FMVSS 210 in a manner which supports General Motors view, as set forth above.

Mr. Samuel Albury
President
Three Wolves and Associates, Inc.
7124 Temple Hills Road
Suite 169
Camp Springs, Maryland 20748

Dear Mr. Albury:

This responds to your letter of June 3, 1991 concerning whether your company would be considered the manufacturer of certain vehicles. Your company is planning to use jeep conversion kits on Chrysler Corporation jeeps. Under one approach, your company would purchase the basic stripped down model jeep from Chrysler and add the body, stereo, air conditioning, tires, running lights, carpeting, and high visibility seats. You state that the body would be one solid piece and that your company would add wheel wells, doors, a solid or canvas top, and a windshield. Alternatively, your company would purchase the chassis, with engine and transmission, from Chrysler and add the above items.

I am pleased to have this opportunity to explain our regulations to you. Some background information on Federal motor vehicle safety laws and regulations may be helpful. As you are aware, the National Highway Traffic Safety Administration (NHTSA) is authorized, under the National Traffic and Motor Vehicle Safety Act (15 U.S.C. 1381 et seq., the Safety Act), to issue safety standards applicable to new motor vehicles and certain items of motor vehicle equipment. NHTSA, however does not approve motor vehicles or motor vehicle equipment, nor do we endorse any commercial products. Instead, the Safety Act establishes a "self-certification" process under which each manufacturer is responsible for certifying that its products meet all applicable safety standards.

I will address the responsibilities of your company under the Safety Act in each of the situations you described. First, if your company purchased a stripped down vehicle from Chrysler and made the modifications described, it could be considered an alterer under our regulations. Under 49 CFR Part 567, Certification, an alterer is defined as:

A person who alters a vehicle that has previously been certified . . . other than by the addition, substitution, or removal of readily attachable components such as mirrors or tire and rim assemblies, or minor finishing operations such as painting, . . . before the first purchase of the vehicle in good faith for purposes other than resale . . . .

As an alterer, your company would be required to certify compliance of its vehicles with the Federal Motor Vehicle Safety Standards in accordance with 49 CFR Part 567. The only exception would be if:

1. The modifications consisted solely of "readily attachable components;" or

2. The modifications were only "minor finishing operations."

Whether modifications involve "readily attachable" components depends on the difficulty in attaching those components. In the past, the agency has looked at such factors as the intricacy of installation and the need for special expertise. Without extraordinary ease of installation, NHTSA would not consider modifications involving the addition or substitution of seats to involve "readily attachable" components.

If considered an alterer, your company would be subject to the certification requirements of 49 CFR 567.7. These requirements include provisions that the alterer supplement the existing manufacturer certification label, which must remain on the vehicle, by affixing an additional label. The label would state that the vehicle as altered conforms to all applicable Federal motor vehicle safety standards. The label would also state the alterer and the month and the year in which the alterations were completed.

In addition to these certification requirements, an alterer is considered a "manufacturer" for the purposes of the Safety Act. Among other things, this means an alterer is responsible for notification and remedy of defects related to motor vehicle safety and noncompliances with applicable Federal motor vehicle safety standards, as specified in sections 151-160 of the Safety Act. Alterers also are subject to the requirements of 49 CFR Part 573, Defect and Noncompliance Reports.

Second, as an alternative, your company is considering buying a chassis from Chrysler. In that case, your company would likely be considered a final-stage manufacturer. Under 49 CFR Part 568, Vehicles Manufactured in Two or More Stages, a final-stage manufacturer is defined as:

A person who performs such manufacturing operations on an incomplete vehicle that it becomes a completed vehicle.

Under the regulation, incomplete vehicle is defined as

An assemblage consisting, as a minimum, of frame and chassis structure, power train, steering system, suspension system, and braking system, to the extent that those systems are to be part of the completed vehicle, that requires further manufacturing operations, other than the addition of readily attachable components, such as mirrors or tire and rim assemblies, or minor finishing operations such as painting, to become a completed vehicle.

As a final-stage manufacturer, your company's certification responsibilities would depend on the information provided by the manufacturer of the incomplete vehicle. Under 49 CFR Part 568, the incomplete vehicle manufacturer must furnish your company with a document which states one of the following three things concerning the incomplete vehicle:

1. The vehicle when completed will conform to some or all of the applicable safety standards if no alterations are made to any identified components of the incomplete vehicle;

2. The vehicle when completed will conform to some or all of the applicable safety standards if specific conditions are followed by the final-stage manufacturer;

3. Conformity with some or all of the applicable safety standards is not substantially affected by the design of the incomplete vehicle, so the incomplete vehicle manufacturer makes no representation as to conformity with the standards.

After receiving this document from the incomplete vehicle manufacturer, your company would be required to certify compliance with the safety standards. In addition to these certification requirements, a final-stage manufacturer is considered a "manufacturer" for the purposes of the Safety Act. Among other things, this means a final-stage manufacturer is responsible for notification and remedy of defects related to motor vehicle safety and noncompliances with applicable Federal motor vehicle safety standards, as specified in sections 151-160 of the Safety Act. In addition, final-stage manufacturers are subject to the requirements of 49 CFR Part 573, Defect and Noncompliance Reports.

I am also enclosing a general information sheet for manufacturers of new vehicles. This sheet highlights the relevant Federal statutes and regulations and explains how to obtain copies of the regulations.

I hope that this information is useful. If you have any further questions, please contact John Rigby at 202-366-2992.

Sincerely,

Paul Jackson Rice Chief Counsel

TITLE: FMVSS INTERPRETATION

TEXT: This is in reply to your letter of March 10, 1976, asking whether S4.6(b) of Motor Vehicle Safety Standard No. 108 allows a flashing side marker lamp "in any location on the side of a motor vehicle without having to comply with State law pertaining to side-mounted turn signals."

S4.6(b) allows side marker lamps to flash for signalling purposes. Since a flashing side marker lamp is in essence a side turn signal lamp, any State regulation specifically addressed to location and flash rate of side turn signals would appear to be preempted by Standard No. 108, if the side marker lamp is combined with a side turn signal lamp. If the side turn signal lamp is a separate lamp, then it would be subject to State regulation.

Your inquirer wishes to install "a side marker lamp on each side near the middle of the trailer to flash with the turn signal lamps." If the lamp to be added is not the intermediate side marker lamp required by Standard No. 108 for trailers whose length is 30 feet or more, it would be governed by the California Vehicle Code and not preempted.

We intend to address the issues of side mounted turn signal lamps, flashing side marker lamps, and flashing headlamps in a rulemaking proposal whose publication is imminent, and I will include your letter in the Docket as a comment to be considered.

YOURS TRULY,

DEPARTMENT OF CALIFORNIA HIGHWAY PATROL

March 10, 1976

File No.: 61.A218.A4343

James C. Schultz Chief Counsel National Highway Traffic Safety Administration

We have a question concerning an interpretation of Section S4.6(b) of FMVSS No. 108. This paragraph states that "means may be provided to flash headlamps and sidemarker lamps for signaling purposes".

We have had an inquiry from a supplier to a major trailer manufacturer as to whether or not he can install a sidemarker lamp on each side near the middle of the trailer to flash with the turn signal lamps. The California Vehicle Code provides that "side-mounted turn signal lamps of an approved type projecting a flashing amber light to either side may be used to supplement the front and rear turn signals. Side-mounted turn signal lamps mounted to the rear of the center of the vehicle may project a flashing red light no part of which shall be visible from the front." The Administrative Regulations require the approved side turn signal lamps to meet the same requirements as SAE Standard J914a.

These standards were adopted to assure that lamps installed on a vehicle as a side turn signal lamp had sufficient performance to be of value to other motorists both day and night, whether mounted on a passenger car, a truck or a trailer. A range of mounting heights was established in our regulations so that the side turn signal lamp would be near the eye height of drivers alongside the vehicle.

In the past, the only vehicles flashing the sidemarker lights as allowed by your standard were passenger cars. In these cases, we had read your standard as permitting the minimum number of sidemarker lamps required by your standard to flash but not giving authority for the indiscriminate addition of numerous other sidemarker lamps in other locations on the side of the vehicle.

We do not see any particular problem with allowing a required sidemarker lamp to flash simultaneously with a required turn signal lamp on the same side and on the same end of the vehicle. Unfortunately, one major passenger car manufacturer selected a system that caused the sidemarker lamps to flash alternately with the turn signals which, in our opinion, detracts from the signal value of the required turn signal instead of adding to it, particularily when both signals are seen to flash alternately at certain angles from the front or rear of the vehicle.

We now come to the question. Does Section S4.6(b) permit a manufacturer to install and flash with the turn signal any sidemarker lamp in any location on the side of a motor vehicle or trailer without having to comply with State law pertaining to side-mounted turn signals?

If the answer is "yes", we ask that you consider an appropriate revision to FMVSS No. 108 within the near future. We suggest that an amendment be proposed to require the side turn signals to flash simultaneously and in unison with the appropriate turn signal rather than alternately with the signal. In addition, we request that:

1. Only the minimum required sidemarker lamps on the each end of the vehicle be allowed to flash with the turn signal lamps.

2. Only sidemarker lamps near the eye height of passenger car drivers alongside the vehicle be allowed to flash. Sidemarker lamps at the extreme tops of trucks and trailer lamps are so far removed from the turn signal that another driver seeing them blink would likely be distracted by them instead of relating them to a turn being signaled.

3. New provisions be worded so attempts of various state laws to require higher-performing side mounted turn signals that are effective in the daytime are not placed in limbo because the Federal Standard allows a far less effective lamp of only 0.25 to 0.62 candlepower to flash in its place.

4. High mounted sidemarker lamps on buses not be allowed to flash as part of the turn signal system, because transit buses are permitted in this State to simultaneously flash all clearance and sidemarker lamps as a crime warning signal when driver or passengers are accosted. These signals are visible both from police patrol cars and police helicopters. Before-and-after surveys have shown that they are quite effective in making substantial increases in the rate of apprehension of suspects.

5. Headlamps not be allowed to flash with the turn signal lamps as now permitted. It is more important that a driver of a vehicle be able to see a lighted roadway in the direction in which he is going rather than using the headlamps to supplement an already effective front turn signal.

We would appreciate receiving your interpretation of the flashing headlamp and sidemarker lamp provisions. If you wish, we will be pleased to send you copies of our regulations on side turn signal lamps, alternately flashing headlamps for emergency vehicles, and data on the reduction in crime on buses following the installation of flashing crime warning lamps.

ATTACHMT: Attached to letter dated 8/11/92 from Steven Henderson to Paul Jackson Rice (OCC-7640)

TEXT:

This responds to your letter of August 11, 1992, commenting on my response to you of June 29 with respect to the relationship of your motorcycle headlamp warning device to S5.6 of Federal Motor Vehicle Safety Standard No. 108, the provisions regulating the modulation of motorcycle headlighting systems.

In my letter, I informed you that the device would not comply with the requirements of Standard No. 108, and would affect compliance of the taillamps and turn signal lamps with the standard. I also advised you that if a motorcycle owner could install the device, there would be no violation of Federal law, and that the legality of its use would be determinable under the laws of the individual American states.

In your latest letter, you "agree that the device contravenes the letter of DOT Standard No. 108 as it presently stands." However, "if the device violates the letter of the law while satisfying the spirit or inferred intent of the law in each case," you believe "that the granting of an exception should be considered by the NHTSA."

As I understand it, your principal argument as raised on page 2 of your August 11 letter is that it is improper to consider your device under S5.6 as it is not a motorcycle headlamp modulating system as described in that section. Thus our objections to modulation rate and intensity, based upon the specifications of that section, are misplaced.

Assuming for the sake of argument that you are correct, your device becomes subject to another provision of Standard No. 108 that I did not mention in my June letter. Paragraph S5.1.3 prohibits the installation, as original equipment, of any motor vehicle equipment that impairs the effectiveness of lighting equipment that Standard No. 108 requires. Application of paragraph S5.1.3 returns us to my comments in June that your device would affect compliance of the taillamps and turn signal lamps with Standard No. 108. The taillamps would no longer be steady-burning, as required by S5.5.10(d). It would appear that the turn signal rate would also cease to comply with the flash rate of 60-120 per minute specified by SAE requirements incorporated by reference in Standard No. 108. Thus, under paragraph S5.1.3, installation of the device as aftermarket equipment, if performed by a manufacturer, dealer, distributor, or motor vehicle repair business would continue to be prohibited by Federal law.

Your latest letter also addresses the issues of taillamp and turn signal conformance. You argue that

"a taillight's purpose is to mark the rear of a motor vehicle during

nighttime driving when it would otherwise be invisible. For this reason the law requires that taillights be lit at night. The law makes no such requirement during the day. The law does require that motorcycle headlights be lit during the day. *** At night the taillight will always be steady- burning as required by S5.5.10(d) because the flasher device is only able to induce taillight flicker during daylight hours due to the photocell circuitry incorporated to prevent the headlamp from generating strobe effects at night. Therefore, the device is in compliance with S5.5.10(d) as it will cause the taillight to flash only at times that it is not required by law to be lit."

The law that applies to your argument is Standard No. 108. Paragraph S5.5.7(b) states in pertinent part that "On each...motorcycle...when the headlamps are activated in a steady-burning state, the taillamps...shall also be activated." Thus, under Standard No. 108 the taillamps must always be activated when the headlamps are activated.

The device also functions through the horn button to cause the turn signal lamps to flash at a rate higher than the maximum permitted by Standard No. 108. In your view, the situation in which the turn signal and horn button are in simultaneous use will be rare. However, if they are used together, "the SAE-specified turn signal flash of 1-2 hz will be perceptually present, the hazard signal flash of 10 hz will also be perceptually present at the same location, and the two signals will not interfere."

We consider that paragraph S5.1.3 applies here as well, and that a flash of 10 hz would impair the effectiveness of the required turn signal flash of 1-2 hz. There could be another undesirable consequence as well. When NHTSA proposed allowing modulating headlamps, commenters were concerned that the flashing might trigger a photic reaction, akin to an attack of epilepsy, in onlookers. NHTSA observed that the reaction was most likely to occur at a frequency of 10 hz against a very dark background. Although your device does not operate at night, its frequency is at the threshold where photic reactions can occur, and we want to bring this fact to your attention.

The agency shares your concern with improving the detectability of motorcycles and their riders. You have suggested writing an "exception" in Standard No. 108 for a period of one or two years so that the safety benefits of the device can be evaluated. We have a procedure under which a manufacturer of motorcycles can petition for a temporary exemption of up to two years, applicable to 2,500 vehicles per year, on the basis that it would facilitate the development and field evaluation of an innovative safety device. Perhaps you can interest a manufacturer in petitioning for a temporary exemption from Standard No. 108 on this basis.

You may also petition the agency for rulemaking to amend Standard No. 108 in a manner that would allow your device. A petition must set forth facts which it is claimed establish that a change in the standard is necessary, and a brief description of the changes which should be made. This means that you should show how your device is expected to improve safety, or, at a minimum, not decrease the existing level of safety. The agency has no plans to initiate rulemaking on its own initiative to permit your device.

ATTACHMT: Attached to letter dated 6-3-91 from Samuel Albury to Chief Counsel, NHTSA (OCC 6112)

TEXT:

This responds to your letter of June 3, 1991 concerning whether your company would be considered the manufacturer of certain vehicles. Your company is planning to use jeep conversion kits on Chrysler Corporation jeeps. Under one approach, your company would purchase the basic stripped down model jeep from Chrysler and add the body, stereo, air conditioning, tires, running lights, carpeting, and high visibility seats. You state that the body would be one solid piece and that your company would add wheel wells, doors, a solid or canvas top, and a windshield. Alternatively, your company would purchase the chassis, with engine and transmission, from Chrysler and add the above items.

I am pleased to have this opportunity to explain our regulations to you. Some background information on Federal motor vehicle safety laws and regulations may be helpful. As you are aware, the National Highway Traffic Safety Administration (NHTSA) is authorized, under the National Traffic and Motor Vehicle Safety Act (15 U.S.C. S1381 et seq., the Safety Act), to issue safety standards applicable to new motor vehicles and certain items of motor vehicle equipment. NHTSA, however does not approve motor vehicles or motor vehicle equipment, nor do we endorse any commercial products. Instead, the Safety Act establishes a "self-certification" process under which each manufacturer is responsible for certifying that its products meet all applicable safety standards. I will address the responsibilities of your company under the Safety Act in each of the situations you described. First, if your company purchased a stripped down vehicle from Chrysler and made the modifications described, it could be considered an alterer under our regulations. Under 49 CFR Part 567, Certification, an alterer is defined as:

A person who alters a vehicle that has previously been certified . . . other than by the addition, substitution, or removal of readily attachable components such as mirrors or tire and rim assemblies, or minor finishing operations such as painting, . . . before the first purchase of the vehicle in good faith for purposes other than resale . . . .

As an alterer, your company would be required to certify compliance of its vehicles with the Federal Motor Vehicle Safety Standards in accordance with 49 CFR Part 567. The only exception would be if:

1. The modifications consisted solely of "readily attachable components;" or

2. The modifications were only "minor finishing operations."

Whether modifications involve "readily attachable" components depends on the difficulty in attaching those components. In the past, the agency has looked at such factors as the intricacy of installation and the need for special expertise. Without extraordinary ease of installation, NHTSA would not consider modifications involving the addition or substitution of seats to involve "readily attachable" components.

If considered an alterer, your company would be subject to the certification requirements of 49 CFR S567.7. These requirements include provisions that the alterer supplement the existing manufacturer certification label, which must remain on the vehicle, by affixing an additional label. The label would state that the vehicle as altered conforms to all applicable Federal motor vehicle safety standards. The label would also state the alterer and the month and the year in which the alterations were completed.

In addition to these certification requirements, an alterer is considered a "manufacturer" for the purposes of the Safety Act. Among other things, this means an alterer is responsible for notification and remedy of defects related to motor vehicle safety and noncompliances with applicable Federal motor vehicle safety standards, as specified in sections 151-160 of the Safety Act. Alterers also are subject to the requirements of 49 CFR Part 573, Defect and Noncompliance Reports.

Second, as an alternative, your company is considering buying a chassis from Chrysler. In that case, your company would likely be considered a final-stage manufacturer. Under 49 CFR Part 568, Vehicles Manufactured in Two or More Stages, a final-stage manufacturer is defined as:

A person who performs such manufacturing operations on an incomplete vehicle that it becomes a completed vehicle.

Under the regulation, incomplete vehicle is defined as

An assemblage consisting, as a minimum, of frame and chassis structure, power train, steering system, suspension system, and braking system, to the extent that those systems are to be part of the completed vehicle, that requires further manufacturing operations, other than the addition of readily attachable components, such as mirrors or tire and rim assemblies, or minor finishing operations such as painting, to become a completed vehicle.

As a final-stage manufacturer, your company's certification responsibilities would depend on the information provided by the manufacturer of the incomplete vehicle. Under 49 CFR Part 568, the incomplete vehicle manufacturer must furnish your company with a document which states one of the following three things concerning the incomplete vehicle:

1. The vehicle when completed will conform to some or all of the applicable safety standards if no alterations are made to any identified components of the incomplete vehicle;

2. The vehicle when completed will conform to some or all of the applicable safety standards if specific conditions are followed by the final-stage manufacturer;

3. Conformity with some or all of the applicable safety standards is not substantially affected by the design of the incomplete vehicle, so the incomplete vehicle manufacturer makes no representation as to conformity with the standards.

After receiving this document from the incomplete vehicle manufacturer, your company would be required to certify compliance with the safety standards. In addition to these certification requirements, a final-stage manufacturer is considered a "manufacturer" for the purposes of the Safety Act. Among other things, this means a final-stage manufacturer is responsible for notification and remedy of defects related to motor vehicle safety and noncompliances with applicable Federal motor vehicle safety standards, as specified in sections 151-160 of the Safety Act. In addition, final-stage manufacturers are subject to the requirements of 49 CFR Part 573, Defect and Noncompliance Reports.

I am also enclosing a general information sheet for manufacturers of new vehicles. This sheet highlights the relevant Federal statutes and regulations and explains how to obtain copies of the regulations.

I hope that this information is useful. If you have any further questions, please contact John Rigby at 202-366-2992.

ATTACHMT: LETTER DATED 11/16/88 FROM TERRY HUDYMA -- LAFORZA AUTOMOBILES TO CHIEF COUNSEL NHTSA; REF 49CFR 567, CERTIFICATION; OCC 2857; LETTER DATED 05/06/85 FROM JOFFREY R. MILLER CHIEF COUNSEL TO HAYLEY ALEXANDER

TEXT: Dear Mr. Hudyma:

Thank you for your letter requesting an interpretation of 49 CFR Part 567, Certification. Specifically, you asked about certification requirements for multipurpose passenger vehicles that will be assembled in Italy and in Michigan. I apologize for the d elay in this response. The vehicles in question will be assembled in Italy to the extent that they will be "complete with everything except the engine (and associated equipment such as ignition and air conditioning, etc.), transmission and transfer case in Italy." These assemblies will then be imported into the United States where the vehicles will be completed. You state that both the operations in Italy and in Michigan will be performed pursuant to a contract with LAFORZA, who will have "complete co ntrol over the manufacturing process at all times."

It is your understanding that in the fact situation described above, LAFORZA is considered to be the manufacturer of the vehicle and therefore LAFORZA is responsible for affixing the certification label on the completed motor vehicle pursuant to 49 CFR P art 567. You asked us to confirm this interpretation. We cannot do so. Under our law and regulations, the company that completes the vehicles in Michigan is a "manufacturer" of the vehicles in question. The information provided in your letter is inad equate to allow us to determine whether LAFORZA might also be considered a "manufacturer" of these vehicles.

The first issue to be addressed in our analysis is whether the products in question are "incomplete vehicles" when they arrive in the United States. An "incomplete vehicle" is defined at 49 CFR @568.3 as:

. . . an assemblage consisting, as a minimum, of frame and chassis structure, power train, steering system, suspension system, and braking system, to the extent that those systems are to be part of the completed vehicle, that requires further manufact uring operations, other than the addition of readily attachable components,

such as mirrors or tire and rim assemblies, or minor finishing operations such as painting, to become a completed vehicle.

Your letter states that the products that arrive in the United States will not have an engine or transmission, which means they will not have a power train.

Accordingly, @568.3 makes clear that these products would not be "incomplete vehicles" for the purposes of our regulations. In previous interpretations, we have referred to products that do not qualify as "incomplete vehicles" as an "assemblage of items of motor vehicle equipment". In those previous letters, we have stated that the assemblage should be labeled as items of motor vehicle equipment for importation into the United States and that the importer of the assemblage must certify that each item of motor vehicle equipment that is covered by a Federal motor vehicle safety standard complies with such standard. See the enclosed May 6, 1985 letter to Mr. Hayley Alexander.

This finding also means that the Italian company that produces these "assemblages of items of motor vehicle equipment" is not a "manufacturer" of motor vehicles with respect to the vehicles in question. Section 102(5) of the National Traffic and Motor V ehicle Safety Act (15 U.S.C. 1391(5); the Safety Act) defines a "manufacturer" as "any person engaged in the manufacturing or assembling of motor vehicles or motor vehicle equipment, including any person importing motor vehicles or motor vehicle equipme nt for resale." In this case, the Italian company producing the assemblage of items of motor vehicle equipment has not manufactured or assembled any motor vehicles, nor has it imported any motor vehicles. Hence, it does not fit the statutory definition of a "manufacturer" of the vehicles in question.

After these assemblages are imported into the United States, the operations performed by the Michigan company will transform the items of motor vehicle equipment into a motor vehicle. Therefore, the Michigan company would be a "manufacturer" of these ve hicles for the purposes of the Safety Act and our regulations. Since @567.4(g)(1) requires the certification label to include the name of the manufacturer, the vehicles could comply if the name of the Michigan company were shown on the certification lab el.

The information in your letter was inadequate to allow us to make even a tentative determination of whether LAFORZA may also be considered a manufacturer of these vehicles. The agency discussed the issue of vehicles with more than one "manufacturer" at length in its proposal to establish rules of attribution for determining which of the manufacturers would be responsible for complying with the phase-in requirements in Standard No. 208, Occupant Crash Protection (49 CFR @571.208). In that proposal, NHT SA said:

Since the National Traffic and Motor Vehicle Safety Act places the responsibility of compliance with safety standards on manufacturers, the agency does not have authority to attribute a vehicle to a party other than one of the vehicle's manufacturers. However, the agency considers the language in section 102(5) of the Vehicle Safety Act that a manufacturer is "any person engaged in the manufacturing or assembling of motor vehicles . . ." to be sufficiently broad to

include sponsors, depending on the circumstances. For example, if a sponsor contracts for another manufacturer to produce a design exclusively for the sponsor, the sponsor may be considered the manufacturer. This follows from application of basic princ iples of agency law. In this case, the sponsor is the principal. On the other hand, the mere purchase of vehicles for resale by a company which also is a manufacturer of motor vehicles does not make the purchaser the manufacturer of those vehicles. 50 FR 14589, at 14596; April 12, 1985.

According to your letter, LAFORZA has a contractual relationship with the company in Intaly that is producing the assemblage of items of motor vehicle equipment and a contractual relationship with the company in Michigan that is assembling the motor vehi cle. These contractual relationships led you to assert that ". . . LAFORZA Automobiles will have complete control of the manufacturing process at all times." If LAFORZA merely has contractual relationships under which it purchases products for resale fr om the companies in Italy and Michigan, LAFORZA would not be considered the manufacturer of those vehicles. If you can provide us with information about any role LAFORZA has in producing these vehicles besides contracting with other companies to assembl e the vehicles, we will review that information and offer our interpretation of whether LAFORZA could be considered a "manufacturer" of these vehicles for the purposes of the Safety Act and our regulations.

Dear Mr. Moore:

This responds to your letter requesting interpretation of Federal Motor Vehicle Safety Standard (FMVSS) No. 108, Lamps, Reflective Devices, and Associated Equipment. Specifically, you asked several questions relating to the standards requirements for effective projected luminous lens area, including the permissibility of using light-emitting diodes (LEDs) to meet those requirements. Our responses to those questions are set forth below. We note that your letter also raised concerns regarding the agencys enforcement of these requirements of Standard No. 108. We are referring the enforcement-related aspects of your letter to our Office of Vehicle Safety Compliance, which will respond to those questions in a separate letter.

By way of background, the National Highway Traffic Safety Administration is authorized to issue FMVSSs that set performance requirements for new motor vehicles and items of motor vehicle equipment (see 49 U.S.C. Chapter 301). This agency does not provide approvals of motor vehicles or motor vehicle equipment, nor do we endorse any commercial products. Instead, manufacturers are required to certify that their vehicles and equipment meet applicable standards. Also, it is unlawful for dealers to sell motor vehicles or motor vehicle equipment that do not meet applicable standards.

Your first question seeks clarification of the legal definition of Effective Projected Luminous Lens Area or Effective Light Emitting Surface including whether there have been any recent amendments or interpretations to that aspect of the standard. Both terms are defined in 49 CFR 571.108 S4.

Effective light-emitting surface means that portion of a lamp that directs light to the photometric test pattern, and does not include transparent lenses, mounting hole bosses, reflex reflector area, beads or rims that may glow or produce small areas of increased intensity as a result of uncontrolled light from an area of degree radius around a test point.



Effective projected luminous lens area (EPLLA) means the area of the orthogonal projection or the effective light-emitting surface of a lamp on a plane perpendicular to a defined direction relative to the axis of reference. Unless otherwise specified, the direction is coincident with the axis of reference.

These definitions were most recently updated in a final rule published in the Federal Register (69 FR 48805) on August 11, 2004. That rule amended the standard for turn signal lamps, stop lamps, taillamps, and parking lamps to increase compatibility with the requirements of the Economic Commission for Europe (ECE) and to improve the visibility of these lamps. In that rulemaking, the definition for effective light-emitting surface was added to the standard, and the definition of effective projected luminous lens area was modified to its current state (69 FR 48814).

In your letter, you also asked if the EPLLA requirements for stop or turn signal lamps are 7 inches (50 cm/sq) for vehicles less than 80 inches wide and 11 5/8 inches (75 cm/sq) for vehicles over 80 inches wide. The answer to this question is that these are the minimum requirements.

In relevant part, S5.1.1.26 of the standard provides:

On a motor vehicle whose overall width is less than 80 inches:

(a)            The effective projected luminous lens area of a single compartment stop lamp, and a single compartment rear turn signal lamp, shall be not less than 50 square centimeters (7 square inches).

(b)            If a multiple compartment lamp or multiple lamps are used to meet the photometric requirements for stop lamps and rear turn signal lamps, the effective projected luminous lens are of each compartment or lamp shall be at least 22 square centimeters, provided the combined area is at least 50 square centimeters (7 square inches).

With regard to vehicles over 80 inches wide, S5.1.1 of FMVSS No. 108 refers to Table I of the standard (Required Motor Vehicle Lighting Equipment Other Than Headlamps), which in turn refers to SAE J1395 (rev. April 1985) (Turn Signal Lamps for Use on Motor Vehicles 2032 mm or More in Overall Width). Paragraph S5.3.2 of SAE J1395 states that the functional lighted lens area of a single lamp shall be at least 75 cm sq.

You also asked whether there are EPLLA requirements for taillamps, side marker lamps, clearance lamps, and identification lamps. Specifically, you asked whether a manufacturer could use one or two Red Dots of LED light to fulfill FMVSS #108 requirements. The answer is that there is no minimum EPLLA for these lamps. We note, however, that under S5.3 of the standard, these lamps must meet the visibility requirements specified in paragraph S5.3.2, which includes meeting the area requirements listed in Figure 19 or the candela requirements listed in Figure 20. Alternatively, paragraph S5.3.2.4 permits lamps to be located such that they meet the visibility requirements specified in any applicable SAE Standard. The applicable SAE Standards are listed in FMVSS No. 108 in Tables I and III. These tables incorporate by reference SAE J585e (rev. Sept. 1972) with regard to tail lamps, and SAE J592e (rev. July 1977) with regard to side marker, clearance, and identification lamps. Paragraph S3.6 of SAE J585e (rev. Sept. 1977) specifies the photometric requirements for tail lamps, and paragraph S3.4 of SAE J592e (rev. July 1977) specifies the photometric requirements for the other lights. If the photometric requirements of the respective SAE standards incorporated by reference are met by one or more LEDs, then such a lamp would meet the relevant requirements of FMVSS No. 108.

If you have any additional questions, please feel free to contact Ari Scott of my staff at (202) 366-2992.

P.O. Box 631
Colmar, PA 18915

Dear Mr. Unrath:

This responds to your request for an interpretation of how NHTSA's regulations apply to your company's plans to refurbish used vehicles. In a telephone conversation with Dorothy Nakama of my staff, you explained that after refurbishing, the vehicles will have lower gross vehicle weight ratings (GVWRs). You wish to know whether you could add a label showing the lower GVWR to the vehicles' original certification label (which you refer to as the "original Vin Plate").

As explained below, NHTSA does not require the supplementary label on a refurbished--and not newly manufactured--used vehicle. We would, however, encourage you to add the label on the refurbished vehicles, since the label would provide important safety information to the vehicle operator. On the other hand, the modifications you make to the vehicle could be so extensive that the resulting vehicle is considered "new" under our regulations. If the vehicle is a new vehicle, you must certify the vehicle as complying with all applicable Federal motor vehicle safety standards (FMVSS's), and include on your certification label the new GVWR of the vehicle.

Based on the information you provided, the vehicles you are refurbishing are "trucks" under section 571.3 of our regulations. Section 571.3 defines a "truck" as a motor vehicle with motive power "designed primarily for the transportation of property or special purpose equipment." You provided two photographs of the vehicles after they have been refurbished. Your photographs show the refurbished vehicles as carrying 4' x 8' "Advanced Warning Flashing Arrow" signs on flat beds. Since your vehicles are designed for transporting property or special purpose equipment, the vehicles are "trucks" under 571.3.

You describe your refurbishing process in your letter. You state that you will take a used truck with a GVWR of 45,000 or 80,000 pounds (lbs.), "scrap" the body, and check remaining truck parts such as the subframe, brakes, steering system, axles, and

suspension. You will repair and replace those parts, as needed. Next, you will clean and paint the frame and running gear, and add a new support frame and "attenuator mounting hardware with braces." After the vehicle is refurbished, its GVWR will be approximately 25,500 lbs.

As a general rule, NHTSA has no requirements for "used" vehicles. Whether a vehicle is considered new or used depends on the origin of its parts. For example, we regard an assemblage of a new body on a chassis of a vehicle that was previously registered for use on the public roads to be a "used" vehicle and therefore not subject to the FMVSS's. When a modified chassis is being used in the refurbishment, NHTSA has a regulation (49 CFR section 571.7(e)) for determining when the modifications to the used chassis are so extensive that the resulting vehicle will be considered new for the purposes of the FMVSS's. Section 571.7(e) states:

When a new cab is used in the assembly of a truck, the truck will be considered newly manufactured . . ., unless the engine, transmission, and drive axle(s) (as a minimum) of the assembled vehicle are not new, and at least two of these components were taken from the same vehicle. It does not appear that you plan to add a new engine, transmission, or drive axle to each refurbished truck. If you leave the requisite components specified in section 571.7(e) in place from the previous vehicle, we would consider the vehicle you produce to be a used vehicle. However, please keep in mind that you would be subject to the provisions of 49 U.S.C. section 30122(b), which provides that:

A manufacturer, distributor, dealer, or motor vehicle repair business may not knowingly make inoperative any part of a device or element of design installed on or in a motor vehicle ... in compliance with an applicable Federal motor vehicle safety standard . . .

This means that the refurbished truck must continue to meet the FMVSS's that it met before the modification, such as those for braking, lighting and safety belt systems. Any violation of this "make inoperative" prohibition would subject the violator to a potential civil penalty of up to $1,000 for each violation.

You ask whether, after refurbishing the used truck, your company may affix additional labels with a new GVWR to reflect the lower GVWR. Since NHTSA generally does not regulate used vehicles, we do not require or prohibit the addition of a supplementary GVWR label. However, we would encourage you to add the supplementary GVWR label to the vehicle.

As you note, in an interpretation letter of May 24, 1993 to the American Association of Blood Banks (AABB), NHTSA recognized that certain modifications that might be made to a used vehicle (e.g., adding or deleting an axle) could make the originally assigned GVWR inappropriate for the vehicle as modified. In the letter to the AABA, NHTSA stated that although it is not required by our regulations, we believe it would be appropriate in these situations to add a label to the vehicle which indicates the appropriate loaded weight of the modified vehicle. Similarly, in your case, since the GVWR of the refurbished trucks would be much lower than that indicated on the certification label, we believe it would be appropriate for your company to add a label to the trucks which indicates the appropriate loaded weight of the refurbished truck.

As noted at the beginning of this letter, it is possible that your modifications could result in a "new" vehicle. You indicate that, if needed, you could replace the vehicle's subframe, brakes, steering system, axles, suspension, and/or support frame. If you were to remove all the drive components from the frame of the original vehicle and add new drive components or rebuilt drive components from different vehicles, the vehicle would be a new vehicle and would have to be certified by you as complying with all applicable FMVSS's in effect on the date of the remanufacture of the new vehicle.

You also asked that NHTSA "approve" your proposed operations. NHTSA has no authority to "approve" refurbishing operations. Under our regulations, manufacturers of new vehicles "self-certify" that their vehicles comply with all applicable FMVSS's. Likewise, businesses refurbishing used vehicles must assure themselves that the resulting vehicle continues to meet the FMVSS's that it met before the modification. NHTSA can examine the refurbisher's determination in the context of an enforcement proceeding.

I hope this information is helpful. If you have any other questions, please contact Dorothy Nakama at this address or by telephone at (202) 366-2992.

Sincerely,

Mr. Terry M. Habshey
Oxytire Incorporated
7000 Highway 25
Montevallo, AL 35115

Dear Mr. Habshey:

This responds to your March 6, 1995 letter to Philip Recht, our former Chief Counsel, and your telephone conversations with Walter Myers of my staff in which you requested a "new D.O.T. number." As discussed below, we are unable to provide you a tire manufacturer's identification mark since the operations you perform on tires are not sufficient to make you the manufacturer of the tires.

You explained that your company is a global exporter of tires, particularly to third world countries, but that you intend to distribute tires domestically in the future. You stated that you obtain new tires from different manufacturers consisting of original equipment overruns, blems, etc., and that by a new process you intend to remove "most" of the information from the tire sidewalls. The new process includes removing a thin layer of rubber from the tire sidewall, then vulcanizing a layer of new rubber onto the sidewall. The new layer will contain a new "registered" trade name, logo, and "identifying marks along with the size, safety information, mounting instructions, maximum and minimum inflating instructions, etc." You emphasized that all tires will be new and meet "all minimum standards established by the Department of Transportation."

Before addressing your request, let me first provide some background information. Chapter 301 of Title 49, U.S. Code (hereinafter Safety Act), authorizes the National Highway Traffic Safety Administration (NHTSA) to issue Federal motor vehicle safety standards (FMVSS) applicable to new motor vehicles and new items of motor vehicle equipment sold in or imported into the United States. Tires are considered motor vehicle equipment. The Safety Act establishes a self-certification system in which manufacturers certify that their products comply with all applicable FMVSSs effective on the date of manufacture. In the case of tires, manufacturers reflect that certification by molding the letters "DOT" into or onto the sidewalls of all their tires manufactured for sale in the United States.

The FMVSSs are not applicable to tires intended solely for export, labeled for export on the tires and on the outside of the container, and exported. See 49 U.S.C. '30112(b)(3); 49 Code of Federal Regulations (CFR) 571.7(d)). Accordingly, you are free to export any tires you want, whether or not they comply with the FMVSSs and after whatever modifications you make to them.

That is not the case, however, with tires distributed for sale in the United States. FMVSS No. 109, New pneumatic tires and FMVSS No. 110, Tire selection and rims, specify performance standards and labeling requirements for new passenger car tires and rims. FMVSS No. 119, New pneumatic tires for vehicles other than passenger cars and FMVSS No. 120, Tire selection and rims for motor vehicles other than passenger cars, specify performance standards and labeling requirements applicable to tires and rims for vehicles other than passenger cars. 49 CFR Part 574, Tire identification and recordkeeping, requires new tire manufacturers to permanently mold into or onto one tire sidewall a tire identification number (TIN) and specifies methods by which new tire manufacturers and new tire brand name owners shall maintain records of tire purchasers. 49 CFR Part 575.104, Uniform tire quality grading standards (UTQGS), requires new motor vehicle and new tire manufacturers and brand name owners to provide information to consumers concerning the relative performance of passenger car tires in the areas of treadwear, traction, and temperature resistance. The UTQGS grades are also required to be molded into or onto the tire sidewall.

The labeling requirements specified in the regulations referred to above apply to the actual tire manufacturers and/or brand name owners, and the required information, including the DOT symbol and the TIN, must appear on all new tires before they can be sold to their first retail purchasers. A tire distributor or dealer cannot legally remove any of the required information from new tire sidewalls. The required information on new tires is intended for safety purposes, purchaser information, and to enable this agency to identify the manufacturer in the event of a noncompliance or defect in a tire line or lot.

A "manufacturer" is defined in 49 U.S.C. '30102(a)(5) as one who manufactures or assembles motor vehicles or equipment or one who imports motor vehicles or equipment for resale. The operations you describe would not be sufficient to make you the manufacturer of the tires in question. According to your letter, you would, for marketing reasons, remove a thin layer of the surface area of the sidewalls of the tires so that most of the existing information is removed. You would then apply a new thin layer of rubber containing new information. Your operations would thus not be changing the basic tire as such but simply changing the labeling. A change in labeling would not change who manufactured the tire. Thus, since you would not be a manufacturer of tires, you may not obtain a manufacturer's identification mark in accordance with 49 CFR '574.6. Only tire manufacturers or retreaders may obtain that mark.

49 U.S.C. '30122(b) prohibits manufacturers, distributors, dealers, and/or motor vehicle repair businesses from knowingly making inoperative any part of a device or element of design installed on or in a motor vehicle or item of equipment in compliance with applicable FMVSSs unless that individual reasonably believes that the vehicle or equipment will not be used when the device or element is inoperative. Thus, removal of the labeling information required to be marked on tire sidewalls in accordance with the standards and regulations discussed above could be a violation of '30122(b), which could subject the violator to civil penalties of up to $1000 per violation, or up to $800,000 for a series of related violations.

In summary, the Safety Act does not apply to tires intended solely for export. Thus, those tires are not required to comply with any FMVSSs. However, all new or retreaded tires sold or imported into the United States for sale must comply with all applicable FMVSSs and regulations as discussed above. Distributors and dealers may not remove any of the labeling information required to be marked on new tires by the actual manufacturers and/or brand name owners of those tires. Removal of that information could make inoperative an element of design on those tires, which could constitute a violation of 49 U.S.C. '30122(b).

I hope this information is helpful to you. Should you need additional information or have further questions, please feel free to contact Mr. Myers at this address or at (202) 366-2992.

Sincerely,

John Womack Acting Chief Counsel
