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.

TITLE: FMVSS INTERPRETATION

TEXT: This responds to your question, raised during a meeting with Carl Clark, Vernon Bloom, Harry Thompson and Edward Glancy, whether any Federal motor vehicle safety standard precludes the importation or sale of your anti-theft device called "Hyperblock." The device works by preventing release of the brakes. Installation of the device requires cutting into a vehicle's braking system.

By way of background information, the agency does not give approvals of vehicles or equipment. The National Traffic and Motor Vehicle Safety Act places the responsibility on the manufacturer to ensure that its vehicles or equipment comply with applicable requirements. A manufacturer then certifies that its vehicles or equipment comply with all applicable standards. We note that the term "manufacturer" is defined by section 102(5) of the Act to mean "any person engaged in the manufacturing or assembling of motor vehicles or motor vehicle equipment, including any person importing motor vehicles or motor vehicle equipment for resale." [Emphasis added.]

The agency does not have any regulations covering anti-theft devices that work by preventing release of the brakes. However, since installation of Hyperblock requires cutting into a vehicle's braking system, it may affect a vehicle's compliance with other safety standards.

If your device is added to a new motor vehicle prior to its first sale, the person who modifies the vehicle would be an alterer of a previously certified motor vehicle and would be required to certify that, as altered, the vehicle continues to comply with all of the safety standards affected by the alteration. In the case of Hyperblock, this would include Safety Standard No. 105, Hydraulic Brake Systems (49 CFR 571.105). You will find the specific certification requirements for alterers at 49 CFR Part 567.7, Certification. On the other hand, you as the manufacturer of Hyperblock would have no certification requirements, because we have no safety standards applicable to your equipment. However, an alterer would probably require information from you in order to make the necessary certification.

If your device is installed on a used vehicle by a business such as a garage, the installer would not be required to attach a certification label. However, it would have to make sure that it did not knowingly render inoperative the compliance of the vehicle with any safety standard. This is required by section 108(a)(2)(A) of the National Traffic and Motor Vehicle Safety Act, which states in relevant part:

No manufacturer, distributor, dealer, or motor vehicle repair business shall knowingly render inoperative, in whole or part, any device or element of design installed on or in a motor vehicle or item of motor vehicle equipment in compliance with an applicable Federal motor vehicle safety standard. . .

You indicated at the aforementioned meeting that installation of Hyperblock does not affect a vehicle's braking performance. You also indicated that Hyperblock maintains the integrity of a vehicle's split system. In addition to requirements in those areas, Standard No. 105 establishes brake system integrity requirements, requiring that a braking system be able to withstand a series of spike stops. You may wish to consider testing Hyperblock as to whether it affects a vehicle's compliance with the spike stop test requirements, if you have not done so already. We suggest that you carefully examine all of Standard No. 105's requirements to determine the degree to which installation of your device affects compliance with the standard.

While we do not have any opinion as to the safety of your particular device, we do have a general concern about the safety of anti-theft devices which work by preventing release of the brakes. We note that some manufacturers state in their service manuals that hydraulic brake locking devices should not be used on their vehicles.

Should a safety-related defect be discovered in your device, whether by the agency or yourself, you as the manufacturer would be required under sections 151 et seq. of the Act to notify vehicle owners, purchasers, and dealers and provide a remedy for the defect.

Finally, in addition to the provisions of Federal law discussed above, there is a possibility of liability in tort should your device prove to be unsafe in operation. You may wish to consult a local lawyer concerning liability in tort.

TEXT:

This responds to your July 13, 1981, letter asking whether the joints in your school buses that fall within the rear cargo compartment or rear engine compartment must comply with Standard No. 221, School Bus Body Joint Strength.

Standard No. 221 applies to joints that connect body panels to body components. Body panels are defined to include those components that enclose the bus' occupant space. The agency has stated in the past that those portions of a bus falling below the floor level would not be considered as having a function in enclosing occupant space, and accordingly, joints in those area would not be required to comply with the standard's requirements.

Applying the standard to the joints that you question, appears that they would not be required to comply with the standard. The agency would consider the walls separating the cargo area or the engine from the remainder of the occupant compartment to be a continuation of the bus floor. Accordingly, joints falling behind and below those walls would not be required to comply with the standard. We do note, however, that the joints along the walls themselves must comply with the standard, since the wall panels enclose the occupant space and provide the separation of the engine or cargo area from the occupant space.

Sincerely,

Frank Berndt Chief Counsel

SUBJECT: FMVSS 221: 41 F.R. 3872, 1-27-76

REFERENCE: 1. Letter Frank Bernett to W.G. Milby dated 4-26-76; N40-30

Dear Mr. Berndt, Federal Motor Vehicle Safety Standard No. 221 School Bus Body Joint Strength covers body panel joints for body panels that enclose the bus occupant space. NHTSA has issued interpretations, see reference, that state components that are not considered to have a function in enclosing the occupant space (Example "...located entirely below the level of floor line...") are not considered a body component and are not subject to the standard.

The enclosed drawing 1034917 illustrates the configurations of a rear center luggage compartment and a rear engine "Pusher" bus. The cross-hatched areas of these cross-sectional views are the occupant space and body panels enclosing this occupant space are covered by the standard.

It is our interpretation that components located entirely within the shaded areas of the drawing, below the floor and below and/or to the rear of the walls between the occupant space and the compartments shown, do not enclose the occupant space, are not considered body components, and are not subject to the standard. Using this interpretation components such as trim panels inside the luggage compartment and panels forming the inner and outer skin of the body that are "located entirely" in the shaded area would not have to meet the joint strength requirements of FMVSS 221.

We feel that this interpretation conforms to the letter of the standard and subsequent interpretations and further conforms to the intent of the standard. We therefore request your early consideration of this matter and confirmation that our interpretation is correct.

Very truly yours,

Thomas D. Turner Manager, Engineering Services

TEXT: We have just returned from the annual National Wheel & Rim Meeting in Phoenix, Arizona. The tone of the meeting from Wheel & Rim Manufacturers was one of concern and rightly so. They have all reprinted and issued their new Rim & Tire Service Manuals ou t-lining and telling tire dealers, fleets, mining and construction users that they MUST NOT USE steel hammers to disassemble or assemble truck rim components. The practice still goes on and probably will until more people are injured and more lawsuits f iled.

For your convenience we have enclosed two pieces of instruction material produced by Rubber Manufacturers Association (RMA) and National Highway, Traffic Safety & Health Administration (NHTSHA). Have your salesmen carry this with them and discuss it wit h your customers.

The logical alternative to the steel duck bill hammer is the "COMBI" Truck & Farm Tire Bead Breaker. If your people will talk about the regulations, your customers will soon start to buy the proper equipment to replace the hammer.

One of the best places to start is with local City, County, State and Federal service operations. They are very cognizant of the OSHA regulations.

Mr. Fred E. Maynard 13208 Creek Park Lane Poway, CA 92064

Dear Mr. Maynard:

This is in reply to your letter of November 14, 1986, to Taylor Vinson of this Office with respect to an automotive lighting product that you have developed.

According to your letter the VISICOM is an electronic message sending unit which incorporates a center high-mounted stoplamp "which will meet all of the standards required by Regulation 108 as to size, light intensity, angle of visibility, etc.." You hav e asked for an opinion "on any potential current or future legal problems that might arise when this product is marketed."

I will be pleased to discuss the relationship of your device to Federal Motor Vehicle Safety Standard No. 108 and the National Traffic and Motor Vehicle Safety Act, but we cannot advise you of problems you might encounter under State or common law. Stand ard No. 108 covers original vehicle equipment and items manufactured to replace original equipment. Paragraph 54.4 of Standard No. 108 states, in pertinent part, that "...no high-mounted stoplamp shall be combined with any other lamp or reflective device ." In our view, this precludes you from offering the VISICOM as either an original center high-mounted stoplamp, or as one intended to replace such a stoplamp on any passenger car manufactured on or after September 1, 1985.

However, you are not precluded by Standard No. 108 or the Act from offering this device as aftermarket equipment on passenger cars manufactured before September 1, 1985. Whether VISICOM is acceptable on these vehicles must be determined by the laws of ea ch State in which the device will be sold or used.

Thank you for your interest in safety. If you have further questions we would be pleased to answer them.

Sincerely, Erika Z. Jones Chief Counsel

Dear Sir:

I was referred to your office by the people at the D.O.T. 1-800 number as the source for an NHTSA legal opinion concerning an automotive accessory product I have developed. Since one of its functions is somewhat related to the third brakelight now requir ed in 1986 or newer automobiles, but no reference to its total concept is made in Regulation 108, I feel its necessary we have an official opinion on any potential current or future legal problems that might arise when this product is marketed.

I have included a complete functional description of the product as we now intend to manufacture It and I Hill certainly appreciate any suggestions or comments you might have and any reference to other NHTSA regulations that define a product concept like VISICOM if any exist at all.

Thanking you in advance I remain:

Sincerely

Fred E. Maynard 13208 Creek Park Lane Poway, Ca. 92064 (619) 748 5883

VISICOM-Product Description

The VISICOM concept can best be described as an electronic sign or message sending unit. It has a number of potential applications with the most attractive market being that of an automotive accessory. In this configuration It will be sold with a number of preprogrammed words and messages the primary purpose of which will be to enhance the safety aspects of automobile operation and promote a higher degree of courtesy on the road.

Physically the unit comes in two sections. the control panel which mounts on the dashboard of the vehicle, and the display section which is to be positioned in the center of the rear window. According to NHTSA (National Highway Traffic Safety Administrat ion) guidelines, a third brakelight would be located in this area of the vehicle in 1986 or newer cars so in order to avoid any conflict with these regulations, the VISICOM automotive model will be supplied with an integrated third brake light which will meet all of the standards required by NHTSA regulation 108 as to size, light intensity, angle of visibility, etc.. This third brakelight will also serve as the base for the display section of the VISICOM which measures approximately 4"H x 17"L x 3"D. Th is enclosure contains virtually all of the electronic control and programming circuits as well as the display itself which consists of six 14 segment alpha-numeric characters 2.5"W x 3.9 "H. Each segment contains a 1.2 watt incandescent bulb which is ene rgized when that segment is required to form a specific number or letter. The words formed by the segmented characters are displayed one at a time for a duration of the seconds with a half second pause in between until the message is complete. Some of th e messages are automatically activated and some of the others continue repeating until the operator ceases the transmission. The messages contained in the system are as follows:

Automatic Messages One Time Display Messages

1. STOP 1. HELLO 2. TURN ------ 2. THANK YOU 3. TURN ------ 3. HAVE A NICE DAY 4. BACKUP 4. SORRY 5. BYEBYE Driver Activated Repeating 6. OK TO PASS Messages 7. NOT OK TO PASS 8.

Dear Mr. Bartlett:

Thank you for your letter of May 5, 1987, concerning Standard No. 301, Fuel System Integrity. You asked the agency to confirm that the requirements set out in the standard apply only to fuel systems installed as items of original equipment in new vehicles and do not apply to aftermarket fuel systems. Several of the Federal Motor Vehicle Safety Standards apply both to original any aftermarket equipment. Standard No. 301, however, applies only to fuel system; installed as items of original equipment in new vehicles.

Although the agency does not have any standards that directly apply to aftermarket fuel systems, manufacturers of motor vehicle equipment, which includes aftermarket fuel systems, are subject to the requirements in sections 151-159 of the Vehicle Safety Act concerning the recall any remedy of products with defects related to motor vehicle safety. I have enclosed an information sheet which briefly describes those responsibilities.

In addition, installation of your product can be affected by section 108(a)(2)(A) of the National Traffic and Motor Vehicle Safety Act. This section prohibits commercial businesses from knowingly rendering inoperative devices or elements of design installed in a vehicle in compliance with the Federal motor vehicle Safety Standards. Thus, a manufacturer, dealer, distributor or motor vehicle repair shop that installs replacement fuel tanks most ensure that it does not knowingly render inoperative the vehicle's compliance with Standard No. 301.

The prohibition of section 108(a)(2)(a) does not apply to individual vehicle owners who alter their own vehicles. Thus, under Federal law, they may install or remove any items of motor vehicle equipment regardless of its effect on compliance with Federal Motor Vehicle Safety Standards. However, the agency encourages vehicle owners not to remove or otherwise tamper with the vehicle safety equipment.

If you have any further questions, please let me know.

Sincerely,

Erika Z. Jones Chief Counsel

Subject: INTERPRETATION OF PARAGRAPH S4.1.1.3 WHICH STATES: "INTERMEDIATE SIDEMARKER DEVICES ARE NOT REQUIRED ON VEHICLES LESS THAN 30 FEET IN OVERALL LENGTH"

Dear Ms. Jones:

We would appreciate it if you could clarify the above referenced section of 108 as it pertains to both tables 2 and 3 which state that trailers, both under 80 and over 80 inches, require intermediate side marker lamps. However, a footnote in both of thes e tables points out paragraph S4.1.1.3 which does not require intermediate sidemarkers on vehicles less than 30 feet in overall length. Our question is in regard to the proper interpretation of vehicles less than 30 feet in overall length. In the case of trailers, does this mean just the trailer as it sits by itself or does it include the power unit that may be pulling the trailer? In the case of straight trucks, that is, trucks in which the power unit and the trailer are not separable, our understanding is that the overall length refers to everything between the front and the rear bumpers.

Thank you for your comments. Please feel free to contact us if there are any questions.

This is in reply to your letter of October 14, 1986, in which you ask how the overall length of vehicles is calculated in determining whether they are to be equipped with intermediate side marker lamps.

With respect to trailers, you ask whether overall length includes the towing unit. No, the overall length to be calculated is only that of the trailer.

As for trucks, you assume that overall length "refers to everything between the front and rear bumpers." I assume that you are including the bumpers in the quoted phase, and that would be correct.

Dear Mr. Chikada:

This is in reply to your letter of November 21, 1986, with reference to the distance between a front turn signal lamp and a lower beam headlamp.

In brief, SAE Standard J588e, incorporated by reference in Standard No. 108 requires a minimum separation distance of 4 inches between the optical axis (filament center) of the front turn signal lamp to the inside diameter of the retaining ring of the lo wer bean headlamp. You have pointed out that a replaceable bulb headlamp does not have a retaining ring, and you have presented two possible substitutes as a measuring point. The first (your Item A) is the outer edge of the headlamp, and the second (your Item B) is the end of the effective area of the reflector. You believe that Item B is the more appropriate.

We concur with your interpretation. Of the two options, the distance to the edge of the effective area of the reflector is the one most similar to the inside diameter of the retaining ring of the lower beam headlamp. The basis for this interpretation is the assumption that the headlamp lens between the outer edge of the headlamp and the edge of the effective area of the reflector is not used for production of the lamp's bean, has mo significant luminance, and therefore will not mask the turn signal.

Dear Ms. Jones,

Re : Distance between a front turn signal lamp and a low beam headlamp)

In Motor Vehicle Safety Standard N0.108, Paragraph 4.3.1.7, the following is prescribed:

S4.3.1.7 The requirement that there be not less than 4 inches between a front turn signal lamp and a low beam headlamp, specified in SAE Standard J588e, "Turn Signal Lamps," September 1970, shall not apply if the sum of the candlepower values of the turn signal lamps Measured at the test point within each group listed in Figure 1c is not less than two and one-half times the sum specified for each group for yellow turn signal lamps.

According to the SAE Standard J588e, the distance is defined as from the optical axis (filament center) of the front turn signal lamp to the inside diameter of the retaining ring of the headlamp unit providing the lower beam. This definition applies only to a standardized headlamp. What definition is appropriate for a replaceable bulb headlamp, in other words, an unstandardized headlamp? We think B in the following definition is appropriate.

A : From the filament center of the front turn signal lamp to the outer edge of a low beam headlamp

B : From the filament center of the front turn signal lamp to the end of the effective area of the reflector of a low beam headlamp

This is in reply to your letter of September 17, 1986, to Mr. Vinson this office asking whether a lamp you wish to import "is legal for highway use in the U.S." The lamp is an aftermarket auxiliary turn signal that is mounted on top of each front fender. The lens is green, but could be any color that is legal for highway use. The lens is visible "from all directions" but could be designed so that it is visible only to the rear, i.e. to the driver.

Federal motor vehicle lighting requirements do not currently apply to aftermarket lamps of this nature. Whether the lamp is legal, therefore, is a question to be answered under the laws of each State in which it will be sold and operated. While we are no t familiar with State lighting laws you nay find that there is a greater likelihood that the auxiliary turn signal lamp will be acceptable if it has a yellow lens, or if its green lens is visible only to the driver.

I hope that this is helpful to you.

Dear Mr. Rounds:

Thank you for your letter of October 22, 1986, requesting an interpretation of how the requirements of Standard No. 20B, Occupant Crash Protection, would apply to a model year 1982 vehicle. The answers to your two specific questions are discussed below.

You first asked about the requirements of S4.1.2.3 of the standard. You asked whether a manufacturer that has chosen to meet that provision of the standard by installing a Type 2 safety belt at each front outboard designated seating position is required to crash test those safety belts. As explained below, S4.1.2.3 does not require the Type 2 safety belts installed in accordance with that requirement to be subjected to a crash test.

S4.1.2 of the standard sets forth the requirements for passenger cars manufactured on or after September 1, 1973, and before September 1, 1986. Thus, those requirements would apply to a model year 1982 passenger car. S4.1.2 provides that a manufacturer s hall meet the requirements of either S4.1.2.1, S4.2.2.2, or S4.1.2.3. Under S4.1.2.3, a manufacturer has the option of installing "a Type 2 seat belt assembly with a nondetachable shoulder belt that conforms to Standard No. 209" at each front outboard de signated seating position. Although Standard No. 209 establishes performance requirements for a safety belt, it does not require the crash testing of the belt.

You also asked whether lap belts installed in accordance with the requirements of S4.1.2.3 in a vehicle's rear seat must be crash tested. The answer is no, rear seat safety belts installed in accordance with S4.1.2.3 do not have to be crash tested. S4.1. 2.3 (c) sets the requirements for rear seats. It provides that a manufacturer may install either a "Type 1 or Type 2 seat belt assembly that conforms to Standard No. 209. . . ." As explained above, Standard No. 209 does not require crash testing for safe ty belts.

As you requested, we are providing you with a certified copy of this letter. If you have any further questions, please let me know.

Sincerely,

Erika Z. Jones Chief Counsel

Dear Ms. Jones:

Re: Interpretation Letter 49 CFR

Section 571.208 5.4.1.2.3

We are writing to request a certified copy of a letter of interpretation regarding conformity with FMVSS 208 as it applies to 1982 MY vehicles.

Specifically, please confirm that where a manufacturer of a 1982 MY vehicle has elected the third option (S.4.1.2.3) and employed type 2 seatbelts (i.e., three point belts), at each front outboard designated seating position, a dynamic crash test is not required. Further, that a 49 CFR Section 571.208 S 5.1 test is also not required with regard to lap belts in the rear designated seating positions where type 2 seatbelts are employed at each front outboard designated seating position.

Your immediate attention to this matter would be most appreciated. Enclosed is a check in the amount of $3.00 to cover administrative expenses.

Yours truly,

PHIL ROUNDS PLR/bv Enclosure
