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. Ho:

This responds to your letter to the National Automobile Dealers Association (NADA), a private organization that represents automobile dealers, asking about the "latest list of approved types and standards of seat belts and child restraints." NADA referred your letter to the National Highway Traffic Safety Administration (NHTSA), because NHTSA is the Federal agency that regulates motor vehicle safety in this country.

You indicate that you would like our latest list of approved seat belts and child restraints to update your list of approved types and standards of the equipment. NHTSA does not keep such a list. This agency does not have a certification process similar to the European Economic Community, in which a manufacturer is required to deliver its equipment to a governmental agency for testing and approval before the product can be sold. Instead, as required by 49 U.S.C. 30101 et seq. ("the Safety Act"), each manufacturer must certify that each of its items of equipment fully satisfies all requirements of the applicable Federal motor vehicle safety standards. In the case of seat belts and child seats, each belt and child restraint that is sold in or imported into the United States must be certified as complying with Safety Standard No. 209 and 213 (49 CFR 571.209 and 571.213), respectively. The standards set forth both performance and labeling requirements that must be satisfied by the belts and the child restraints.

Further, NHTSA does not require that the manufacturer's certification be based on a specified number of tests of the equipment item or on any tests at all. Pursuant to the Safety Act, we only require that the certification be made with the exercise of due care on the part of the manufacturer. It is up to the individual manufacturer in the first instance to determine what data, test results, or other information it needs to enable it to certify that its equipment complies with the standards. We would certainly recommend, however, that a manufacturer selling its belt systems or child restraint systems in the United States test those systems according to the test procedures specified in the standards.

I hope this answers your questions. If you need further assistance, please contact Ms. Deirdre Fujita of my staff at (202) 366-2992.

John Womack

Batavia, OH 45103

Dear Mr. Getz:

This responds to your May 15, 1997, letter to the National Highway Traffic Safety Administration (NHTSA), concerning the applicability of our safety standards to your vehicles. You were especially interested in the underride protection standard and the antilock braking system (ABS) standard, both of which become effective in 1998.

You explain that your company manufactures custom trailers. You usually purchase new or nearly complete trailers from a trailer manufacturer and "finish them, primarily inside, for specific applications such as medical trailers." You ask:

The question arises when you consider that we take delivery of a complying trailer several months before our sale. Consequently, we can be delivering our completed trailer in April 1998 which was received by us in December 1997 and thus doesn't incorporate either ABS or newer underride protection. Please confirm that our trailers in such a case are in compliance because the original trailer date of manufacture precedes the effective dates for the rules noted.

Our standards apply to any motor vehicle manufactured on or after the effective date of the standard. If you purchase a new, complete certified trailer before the effective dates of the underride and ABS standards, for "finishing" after the effective date of the standards, compliance with those standards is optional. The work you perform would probably define you to be an "alterer" under 49 CFR 567.7. An alterer is a person who alters a new 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, or who alters the vehicle in such a manner that its stated weight ratings are no longer valid. Section 567.7 requires alterers to allow the original certification label to remain on the vehicle, and to affix an additional label containing, among other information, the statement:

This vehicle was altered by (individual or corporate name) in (month and year in which alterations were completed) and as altered it conforms to all applicable Federal Motor Vehicle Safety Standards affected by the alteration and in effect in (month, year). * * *

Section 567.7 provides that "The second date shall be no earlier than the manufacturing date of the original vehicle, and no later than the date alterations were completed. * * * " Under this section, if you are altering a December 1997 vehicle in April 1998, you are permitted to certify that the vehicle, as altered, conforms to the standards in effect in December 1997.

Similarly, if you purchase a new, incomplete trailer (with accompanying documentation, see 49 CFR 568.4), before the effective dates of the underride and ABS standards for completing after the effective date of the standards, you need not certify compliance with those standards. Our requirement for certifying vehicles manufactured in two or more stages (49 CFR 568.6) specifies that "Each final-stage manufacturer shall complete the vehicle in such a manner that it conforms to the standards in effect on the date of manufacture of the incomplete vehicle, the date of final completion, or a date between those two dates.(1) In the example you provide, the date of manufacture of the incomplete trailer would be which is prior to the effective date of the underride and ABS standards. Thus, those standards would not apply to the vehicle.

I hope this answers your questions. Please contact Deirdre Fujita of my staff at (202) 366-2992 if you need further assistance.

Sincerely,
John Womack
Acting Chief Counsel

1. Note that 568.6 also specifies that this requirement shall, however, be superseded by any conflicting provisions of a standard that applies by its terms to vehicle manufactured in two or more stages. The underride and ABS standards have no such provision.

VALEO Vision

Dear M. Dorleans:

This is in reply to your letter of May 22, 1997, regarding the "Baroptic" lower beam headlamp developed by VALEO. This headlamp is visually/optically aimable, incorporating one removable light source. You have enclosed drawings (Figs. 1-4) illustrating the new headlamp.

You believe that the headlamp would be permitted by Federal Motor Vehicle Safety Standard No. 108, but you have asked the following three questions:

"a) Does the provision in S7.4(a)(3) apply? We think it does not, since the 'Baroptic' is not an integral beam. As a matter of consequence, the ratio between the luminance of each light-emitting surface is not a legal criterion. Nor is the relative contribution of each Fresnel lens to the lowbeam beam pattern."

If you have decided that the "Baroptic" is not an integral beam headlamp system, then paragraph S7.4(a)(3) would not apply since paragraph S7.4 applies only to integral beam headlamp systems. The "Baroptic" lower beam headlamp will be a "replaceable bulb headlamp" regulated under paragraph S7.5 provided that its replaceable light source is designed to conform to the requirements of Appendix A or Appendix B of Part 564 and the appropriate information has been submitted to and accepted by NHTSA.

"b) Where do we need to mark the name of the light source as required in S7.5(g)? We propose to place this mandatory marking on the outer lens (6), in front of the center of the midpoint Fresnel lens if an odd number of lenses is used (Figure 3a), or in between the central Fresnel lenses if their number is even (Figure 3b)."

S7.5(g) requires only that the lens of a replaceable bulb headlamp be marked "in front of " each replaceable light source. The locations you have chosen meet this requirement.

"c) We have the same question and same proposal as above for the 'mark' of the optical axis' as per S7.8.1(b) of FMVSS 108."

S7.8.1(b) requires headlamps to have a mark or markings that are visible from the front of the headlamp . . . to identify the optical axis of the headlamp . . ." These markings " may be on the interior or exterior of the lens or indicated by a mark or central structure on the interior or exterior of the headlamp." The marks for optical axis that are shown in Figure 3(a), Figure 3(b), and Figure 4 of your submission would appear to indicate the optical axis itself of the respective headlamp design, but must be placed in the location necessary for correct aiming and photometric testing.

If you have further questions, you may refer them to Taylor Vinson of this Office (FAX 202-366-2830).

Suite 300
Washington, DC 20005

Dear Mr. Leasure:

This responds to your letter regarding Standard No. 208's labeling and owner's manual requirements for air bag-equipped vehicles. You ask whether the requirements apply to medium and heavy trucks equipped with air bags, and suggest that we adopt an interpretation that the requirements do not apply to these vehicles. We do not interpret the standard as you suggest.

Standard No. 208's air bag labeling and owner's manual requirements are set forth in S4.5.1. While many of the standard's requirements, including those mandating air bags, are expressly limited to vehicles with specified gross vehicle weight ratings, S4.5.1 does not contain any such limitation.

You suggest that the air bag labeling and owner's manual requirements should, nonetheless, be interpreted as not applying to medium and heavy trucks equipped with air bags, because these vehicles are not required to have air bags. You note several facts in support of this argument:

The focus of NHTSA with regard to passive occupant protection has been, and continues to be, light passenger vehicles and not medium and heavy-duty trucks.

While Standard No. 208 applies to passenger cars, multipurpose passenger vehicles, trucks and buses, the standard permits trucks with a gross vehicle weight rating of more than 10,000 pounds the option of only having a Type 1 or Type 2 belt system. (Your letter indicates that all medium and heavy-duty truck manufacturers install Type 2 seat belts as standard equipment.)

In NHTSA's November 1996 final rule specifying installation of new, attention getting labels, it cited compliance dates only for passenger cars, light trucks and vans. Moreover, the focus of the agency in this rulemaking was the protection of children. Medium and heavy-duty trucks are utilized for commercial purposes and therefore often only have provisions for a driver's seat. In cases where there is a passenger seat, it is rarely occupied and even more rarely occupied by children. Currently, no medium or heavy-duty truck manufacturer offers a passenger-side air bag.

You also stated that TMA believes it would be more appropriate for the agency to allow the original warning label specified by Standard No. 208, rather than the new ones, to be used voluntarily in medium and heavy-duty trucks

While we do not disagree that our rulemakings regarding labeling and owner's manual requirements for vehicles equipped with air bags have focused on light vehicles, we nonetheless conclude that the requirements also apply to medium and heavy trucks equipped with air bags. There are several reasons for this conclusion.

First, the standard does not limit the applicability of these requirements to light vehicles or to vehicles required to have air bags. Second, the safety concerns addressed by these requirements apply to all vehicles equipped with air bags and not merely light vehicles. For example, the warning to sit as far back as possible from the air bag and to always use seat belts is relevant to heavy vehicles as well as light vehicles equipped with air bags. I note that manufacturers of vehicles without passenger-side air bags are permitted to omit language concerning the hazards to children from air bags. See Final rule, correcting amendment published in the Federal Register (61 FR 64297) on December 4, 1996. Finally, we believe that, to the extent it might be appropriate to specify different labeling or owner's manual requirements for medium or heavy vehicles than for light vehicles, the issues would most appropriately be addressed in rulemaking.

I hope this information is helpful. If you have any further questions, please feel free to contact Edward Glancy of my staff at (202) 366-2992.

John Womack

Dear Mr. Moore:

This is in reply to your letter of May 28, 1997, to Samuel J. Dubbin, the former Chief Counsel of this agency. You ask for a "reconsideration" of his interpretation letter to you of July 29, 1996.

That letter informed you that we saw no conflict between California Vehicle Code Sec. 25100(e) requiring clearance lamps to be visible from all distances between 500 feet and 50 feet to the front and rear of the vehicle, and paragraph S5.3.1.1.1 of Federal Motor Vehicle Safety Standard No. 108 providing that clearance lamps located other than on the front and rear need not be visible at 45 degrees inboard. In our opinion, S5.3.1.1.1 did not relieve clearance lamps of the requirement that they be visible and meet minimum photometric requirements "directly to the rear" and at 45 degrees outboard.

You disagree with this interpretation, commenting that "perhaps one could see at least one of the so-called Clearance lights 'to the rear' if one were in the left or right lane directly adjacent to the lane" in which the vehicle carrying the clearance lamps were traveling. We do not think that our interpretation was mistaken. It remains our belief that a clearance lamp located other than on the rear of a vehicle, such as on a fender, but which is visible directly to the rear, will be visible without reference to an adjacent lane, and will be visible from 50 to 500 feet directly to the rear of the vehicle as specified by CVC Sec. 25100(e). The issue of whether a particular manufacturer may have violated the standard by recessing its clearance lamps on the side of a vehicle so that they are not visible and do not meet applicable photometric requirements from the rear is a different issue, and does not call into question our prior interpretations.

We appreciate your bringing this matter to our attention.

John Womack

Dear Mr. Hutton:

This replies to your FAX of April 23, 1997, to Richard Van Iderstine of this agency, asking whether there is an error in paragraph S8.9 of Federal Motor Vehicle Safety Standard No. 108, as it appears on page 247 of Title 49 Parts 400 to 999 of the Code of Federal Regulations revised as of October 1, 1996.

You are quite correct. The final sentence of S8.9 in the October 1, 1996, edition begins with the phrase "Distance 'A'". This is an error. The sentence beginning "Distance 'A'" should be the final sentence of S9 as amended on November 28, 1995. The 1996 volume mistakenly placed this amendment in S8.9.

Thank you for calling this matter to our attention. We have arranged for a correction in the next edition of Title 49 Parts 400 to 999.

Dear Mr. Evans:

This is in reply to your letter of May 16, 1997, to Messrs Van Iderstine and Boyd of this agency. For your future reference, the Office of Chief Counsel has been designated as the Office of the National Highway Traffic Safety Administration responsible for providing legal interpretations of the Federal motor vehicle safety standards.

You ask what components of a headlamp must be included when a corrosion test is conducted on it pursuant to Federal Motor Vehicle Safety Standard No. 108. Specifically you ask whether it is "just the housing lens, reflector and bulb?" Because paragraph S8.4(b) "makes a reference to unfixtured," you also ask whether that implies that "the aim and mounting hardware should be included?" Finally, because the connector is to be attached to the bulb, you ask whether that makes "the bulb compression spring a headlamp component?"

The performance requirements to which paragraph S8.4 relates are set forth in paragraph S7.4(h)(3) (applicable to integral beam headlamps) and paragraph S7.5(i) (applicable to replaceable bulb headlamps). These paragraphs require that, after a corrosion test of a headlamp conducted according to paragraph S8.4, "there shall be no evidence of external or internal corrosion or rust visible without magnification." When a headlamp is tested as provided in paragraph S8.4, it is to be tested "with connector attached to the terminals, unfixtured . . . ." Paragraph S4 defines a headlamp test fixture as a test device "whose mounting hardware and components are those necessary to operate the headlamp as installed" on a motor vehicle.

Since the headlamp is to be tested unfixtured, this means that a test headlamp need not be equipped with mounting hardware and associated components at the time of testing for corrosion resistance. However, all other components of the headlamp would be subject to the corrosion test, including its aiming hardware (if so equipped) and the bulb compression spring, and be required to comply with corrosion resistance requirements specified by Standard No. 108.

If you have further questions, you may refer them to Taylor Vinson of this Office (202-366-5263).

Washington, DC 20036

Dear Mr. Doi:

This responds to your letter concerning Standard No. 208's requirements for passenger air bag manual cut-off devices. As you note in your letter, S4.5.4 of the standard permits these devices in vehicles which either do not have rear seats or have rear seats that are smaller than a specified size. You stated that you are studying the feasibility of installing retrofit cut-off switches on such vehicles, and ask two questions concerning this matter.

First, you ask us to confirm your understanding that installation of retrofit cut-off switches in these vehicles would not violate the provision in Federal law that prohibits manufacturers and other commercial entities from making required safety equipment inoperative.(1)

Your understanding is correct. Because Standard No. 208 would have permitted these vehicles to be manufactured with passenger air bag manual cut-off devices when new, and so long as the devices used for retrofit meet all of the requirements specified in the standard for such devices, there would not be any violation of the "make inoperative" provision.

Second, you ask about S4.5.4.3's requirement that the telltale light for the cut-off device be "on the dashboard." You state that you believe the location of the manual cut-off device depicted in an attached drawing "is clearly visible from all front seating positions and may be considered a part of the dashboard." You state that you therefore believe that "placing the telltale lamp and air bag cut-off switch in the attached location between driver and passenger seating positions may comply with the requirements of S4.5.4.3."

As discussed below, we do not agree that the location shown in your drawing is considered a part of the dashboard. Therefore, the design would not comply with S4.5.4.3.

Your drawing shows the location of the manual cut-off device, including both the telltale lamp and air bag cut-off switch, as being on a low-lying portion of a center console which ultimately rises to meet the dashboard. We have previously issued interpretations addressing the issue of where the center console ends and the dashboard begins in the context of Standard No. 201. (Enclosed are copies of an October 27, 1986 letter to Mr. Tsuyoshi Shimizu and a July 21, 1988 letter to Mr. Hiroshi Kato.)

While we recognize that there is sometimes difficulty in determining the dividing line between a dashboard and an adjoining console, we believe the location shown on your drawing is on the console. This conclusion is based on the fact that location appears to be on a low-lying portion of the console, and before any significant rise toward the dashboard. We also note that, while it is difficult to tell from your drawing, there appears to be an indentation or gap that separates the instrument panel from the console. The location shown on your drawing is well below, and apparently rearward of, the indentation or gap.

I hope this information is helpful. If you have any further questions, please feel free to call Edward Glancy of my staff at (202) 366-2992.

Dear Mr. Camp:

This is in reply to your letter of May 29, 1997, to the Administrator asking that the term "overall width" as used in Federal Motor Vehicle Safety Standard No. 108 be interpreted to exclude running boards. Specifically, Ford Motor Company wishes to equip certain pickup trucks and sport utility vehicles with running boards that are wider than currently offered; however to do so would increase the vehicles' "overall width" from 79.8 inches to 85 inches.

Standard No. 108 requires trucks and multipurpose passenger vehicles which are 80 inches or more in overall width to be equipped with clearance lamps and identification lamps. In 1967, the agency clarified, in Note 1 to Standard No. 108, that

"'Overall width' refers to the nominal design dimension of the widest part of the vehicle, exclusive of signal lamps, marker lamps, outside rearview mirrors, flexible fender extensions, and mud flaps, determine (sic) with doors and windows closed and the wheels in the straight-ahead position."

Although the definition of "overall vehicle width" in 571.3(b), which you quote, is substantively identical, it is the interpretation of Standard No. 108's term "overall width" that is the conformance determinant at issue.

You call our attention to the fact that "outside door handles" have also been excluded from the definition through a letter of interpretation to Iveco Trucks of North America dated December 9, 1980. Ford is unclear whether running boards should be included in the measurement for determination of "overall width" but believes that running boards should be treated in a fashion similar to door handles. You point out that the overall width of the vehicles for which you seek exemption is actually 90.5 inches when their exterior rear view mirrors are included.

Our review of the letter to Iveco indicates that we excluded door handles from "overall width" because "they are substantially similar in character to outside rearview mirrors and the other

equipment items listed." We agree that running boards are also similar to these items, and, therefore, they need not be included in the nominal design dimension of the widest part of the vehicle when a manufacturer calculates a vehicle's "overall width" for purposes of compliance with the lighting requirements of Standard No. 108, as long as they do not extend beyond the width of the other items excluded from the definition of "overall width."

Dear Mr. Olsen:

This responds to your letter, addressed to Paul Atelsek of my staff, asking several questions about our safety standards. I apologize for the delay in our response.

You first ask about a proposed design for a passenger air bag (PAB) on-off switch for "two seat cars." You state:

    The proposed solution for deactivating the PAB is as follows:

  • Turn the ignition switch to start position . . .;
  • The start position on the ignition key will activate a PAB switch;
  • The PAB switch, located on the top of the steering column cover, can now be pushed to activate/deactivate the PAB;
  • If the PAB is deactivated, a yellow light in the center console (visible for both people in the front) will be turned on.
  • It is only possible to change the PAB status when the ignition key is in the start position.

You asked whether this system would meet NHTSA's requirements, and whether this agency has "any lamp display that PIVCO can use for the deactivated PAB."

By way of background information, NHTSA has established specific requirements for passenger air bag manual cut-off devices. These requirements are set forth in S4.5.4 of Standard No. 208. I have enclosed a copy of that section revised as of October 1, 1996, and a final rule published on January 6, 1997 (Docket 74-14, Notice 109) which amended that section.

As you will see, your proposed design would not meet the requirements of S4.5.4. For example, it would not meet the requirement specified in S4.5.4.2 that a passenger air bag manual cut-off device must be separate from the ignition switch for the vehicle, "so that the driver must take some action with the ignition key other than inserting it or turning it in the ignition switch to deactivate the passenger air bag." Also, it would not meet the requirement in S4.5.4.3 that the telltale light be located on the dashboard. As to your question concerning whether this agency has "any lamp display that PIVCO can use for the deactivated PAB," S4.5.4 includes several requirements for the display. Among other things, S4.5.4.3 specifies that the telltale must be yellow, and must have the identifying words "AIR BAG OFF" on the telltale or within 25 millimeters of the telltale.

You next ask when the "new FMVSS 201" will influence PIVCO. You state that PIVCO is a small car manufacturer, with only one vehicle line, producing 5,000 cars a year.

Federal Motor Vehicle Safety Standard No. 201; Occupant Protection in Interior Impact was amended by a final rule published on August 18, 1995 (62 FR 16718). This final rule, which established new requirements for head protection, was amended by a notice published on April 8, 1997 (62 FR 16718).

The standard provides manufacturers with four phase-in options for meeting its requirements.

These phase-in options are not dependent on the number of vehicles produced by a manufacturer. Options one and two, found in S6.1.1. and S6.1.2 of the Standard, provide that certain percentages of production manufactured on or after September 1, 1998 must meet the new requirements. The third option, found in S6.1.3 of the Standard, states that manufacturers need not produce any complying vehicles before September 1, 1999 but that all vehicles produced on or after that date must comply. This option, which provides longer lead time than the first two options, was intended to accommodate manufacturers with limited product lines.

The fourth option is applicable only to final stage manufacturers. The term "final stage manufacturer" is defined at 49 CFR 568.3 as "a person who performs such manufacturing operations on an incomplete vehicle that it becomes a completed vehicle." An "incomplete vehicle" is defined in that section as "an assemblage consisting, at a minimum, of frame and chassis structure, power train, steering system, suspension system, and braking system . . . that requires further manufacturing operations . . . to become a completed vehicle." If PIVCO is a "final stage manufacturer," it need not produce any vehicles that comply before September 1, 2002. However, all vehicles manufactured on or after that date must comply.

There is no exclusion from the Federal motor vehicle safety standards (FMVSS) based upon the volume produced by the manufacturer. All motor vehicles must comply with all FMVSS, unless the agency has exempted them from one or more of the standards. NHTSA is authorized by 49 U.S.C. 30113 to exempt, on a temporary basis, a manufacturer whose total yearly production does not exceed 10,000 motor vehicles, from any FMVSS that would cause the manufacturer substantial economic hardship were it required to meet it immediately. The application procedures for such an exemption are contained in 49 CFR 555.5 and 555.6(a). The applicant must not only show hardship, but also that it has tried in good faith to meet the standard from which it requests relief.

Finally, you ask about contact persons within NHTSA. You ask whether it is OK for all communications between PIVCO and NHTSA to go through Mr. Atelsek, and whether there is any other way of communicating with NHTSA, e.g., by fax or e-mail.

In communicating with NHTSA, PIVCO should contact the specific office or person for which it has relevant questions or other business, to the extent it has the knowledge to do so. Requests for legal interpretation should be sent to Chief Counsel, Room 5219, National Highway Traffic Safety Administration, Washington, DC 20590 (FAX 202-366-3820). Questions regarding Standard 208 should be directed to Mr. Edward Glancy (eglancy@nhtsa.dot.gov). Inquiries about Standard 201 should be directed to Mr. Otto Matheke (omatheke@nhtsa.dot.gov).

Sincerely,

John Womack
Acting Chief Counsel
