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.

Mr. Michael D. Payne

One Thorton Court

Potomac Falls, VA 20165

Dear Mr. Payne:

This responds to your letter concerning the speedometer marking requirements of Federal Motor Vehicle Safety Standard (FMVSS) No. 101, Controls, telltales and indicators. You ask whether vehicles can have km/h primary and mph secondary.

By way of background, the National Highway Traffic Safety Administration (NHTSA) is authorized to issue Federal Motor Vehicle Safety Standards (FMVSSs) for new motor vehicles and new items of motor vehicle equipment. See 49 U.S.C. Chapter 301. FMVSS No. 101 is one of the standards we have issued.

FMVSS No. 101 requires speedometers to be labeled with MPH, or MPH and km/h. See Table 1. The intent of the standard is to require speedometer display in miles per hour (MPH), and to allow the addition of kilometers per hour (km/h) to MPH at the option of the manufacturer. The standard does not permit speedometers to be graduated in km/h only, since speed limits in the United State s are communicated on highway signs in MPH alone.

 

The standard specifies that if the speedometer is graduated in both miles per hour and in kilometers per hour, the scales must be identified MPH and km/h, respectively. The standard does not specify, in this situation, that MPH must be primary. However we would not provide a specific interpretation in this area outside the context of a specific design.

 

You state that this provision of FMVSS No. 101 appears to be in violation of Federal law since it was the intent of Congress to designate the metric system as the preferred system for the United States. Moreover, your letter states that you petition NHTSA to change the wording to comply with Federal law. We believe that FMVSS No. 101 is a legally valid exercise of NHTSAs regulatory authority and is not contrary to any Federal law.



We note that NHTSA ordinarily uses the metric system in its FMVSSs. However, the agency is not required to specify the FMVSSs in metric units only. In this particular instance, for reasons explained above, there is a safety reason why the agency does not permit speedometers graduated in km/h only.

Your letter does not meet minimum requirements for NHTSA to consider it a petition under 49 CFR Part 552 Petitions for Rulemaking, Defect, and Noncompliance Orders. Thus, your letter has not been treated as a petition.

I hope this information is helpful. If you have any further questions, please feel free to contact Dorothy Nakama of my staff at this address or by telephone at (202) 366-2992.

Sincerely yours,

Anthony M. Cooke

TITLE: FMVSS INTERPRETATION

TEXT: This is in reply to your letter of September 7, 1976, to Mr. Dyson, formerly of this office, requesting a confirmation that an interpretation of Motor Vehicle Safety Standard No. 108, rendered to the Southern California Rapid Transit District on August 5, 1974, is still valid, and that it can be extended to include identification lamps as well.

In our earlier letter we advised the District that the installation of wiring by a manufacturer enabling a purchaser to connect it to normally steady-burning clearance lamps, enabling them to be flashed to signal a crime in progress, would not violate S4.6(b) which requires clearance lamps to be steady-burning, or S4.1.3 that prohibits installation of motor vehicle equipment which impairs the effectiveness of the lighting equipment required by Standard No. 108. This will confirm that that interpretation is still valid.

Your letter, however, raises two additional issues which deserve to be answered for the record. The first is whether the bus manufacturer rather than the purchaser may make the connection, and the second is whether identification lamps may also be included in the warning system. Since it is our opinion that use of the clearance lamps in an emergency mode creates an item of lighting equipment not required by Standard No. 108 and hence outside its coverage, we have concluded that the manufacturer may connect both clearance and identification lamps to the emergency circuit without any resultant nonconformances with S4.6(b) and S4.1.3.

I hope this is responsive to your request.

SINCERELY,

THE FLXIBLE COMPANY

Office of the Chief Counsel National Highway Traffic Safety Administration

Attention: R. B. Dyson

Reference: FMVSS No. 108, Lamps, Reflective Devices, and Associated Equipment

Our Company, a manufacturer of urban transit buses, is in receipt of a recent procurement solicitation for transit vehicles from the Southern California Rapid Transit District (SCRTD), Los Angeles, California, which specifies a requirement for a "crime alarm light" system. This system incorporates appropriate circuits, silent switches, a silent electronic flasher unit and a dual filament bulb, all of which are to be used in conjunction with the clearance lamps. Activation of the switch will cause the clearance lamps to flash signalling a crime-in-progress.

We recognize that Section S4.6(b), FMVSS No. 108, permits the flashing of headlamps and side marker lamps for signalling purposes. However, the referenced Section does not stipulate that the flashing of clearance lamps (and identification lamps which are normally on the same circuit) is permitted; in fact, S4.6 (b) requires "all other lamps shall be steady-burning...".

Effective January 1, 1976, the California Vehicle Code authorized the flashing of clearance lamps as crime alarm lights. A copy of this amendment is attached for your information. Also attached is a copy of an August 5, 1974, letter from your office to the SCRTD stating that the operation of the clearance lamps as a warning lamp causes the clearance lamps to become an item of lighting equipment outside the coverage of Standard No. 108. We are assuming the same provision would apply to identification lamps.

Since your previous letter was written over two years ago and in order to assure ourselves that, as a vehicle manufacturer our product is not in violation of S4.6, FMVSS No. 108, when we comply with an operator's requirement, we request that a similar letter, addressed to the Flxible Company, indicating that the flashing of clearance lamps and/or identification lamps as a warning lamp system is not prohibited by Standard No. 108 be forwarded for retention in our Part 576, Record Retention, file. It is suggested that perhaps an amendment to FMVSS No. 108 incorporating this information is in order.

We thank you for your effort in providing the above requested letter.

Finbarr J. O'Neill, Esq. Vice President and General Counsel Hyundai Motor America 7373 Hunt Avenue Garden Grove, CA 92642-2669

Dear Mr. O'Neill:

Thank you for your letter on behalf of Hyundai Motor Company of Korea (HMC)' requesting clarification of how the requirements of Standard No. 208, Occupant Crash Protection, would affect a manufacturer whose vehicles are distributed in the United States by two separate entities. I regret the delay in answering your letter.

You explained that vehicles manufactured by HMC are currently imported and distributed i the United States by Hyundai Motor America. However, in February 1987, HMC will manufacture 30,000 vehicles for distribution by Mitsubishi Motor Sales of America, Inc. (Mitsubishi) to be sold under the Mitsubishi trademark. You asked if the vehicles sold by HMC to Hyumdai Motor America and Mitsubishi must separately comply with the automatic restraint phase-in requirements of Standard No. 208.

During the phase-in of the automatic restraint requirement, each manufacturer is required to certify that a certain percentage of its vehicles meet thy automatic restraint requirement. For example, for the period September 1, 1986, through August 31, 1987, a manufacturer must equip 10 percent of its vehicles with automatic restraints. On March 21, 1986, NHTSA adopted a final rule which affects how a vehicle manufactured by one company and sold by another is to be counted for the purposes of the phase-in. The rule permits manufacturers to determine by contract in whose fleet the vehicle would be counted. Thus, for example, HMC could provide by contract with Mitsubishi America that all of the vehicles HMC manufactures for Mitsubishi are to be counted as a part of HMC's fleet. Thus, under that contract, HMC would have to count all the vehicles it manufactures for sale to Hyundai Motor America and to Mitsubishi and ensure that 10 percent of that total are equipped with automatic restraints during the first year of the phase-in.

In the absence of a contract, NHTSA's final rule of March 21, 1986, adopted several rules of attribution. The one relevant to your situation is that a vehicle imported into the United States is attribute to its importer. Thus, in the absence of a contract between HMC and Mitsubishi, the vehicles imported by Mitsubishi from HMC would be counted in Mitsubishi's fleet and 10 percent of Mitsubishi's total fleet would have to have automatic restraints.

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

Sincerely,

Erika Z. Jones Chief Counsel

Erika Z. Jones Chief Counsel National Highway Traffic Safety Administration 400 Seventh Street, S.W. Washington, D.C. 20590

Dear Ms. Jones:

I am writing on behalf of Hyundai Motor Company of Korea ("HMC"). We request clarification of 49 CFR Section 571.208 as it relates to a manufacturer whose vehicles are distributed in the United States by two separate entities.

At present, motor vehicles manufactured by HMC are imported and distributed in the United States by Hyundai Motor America, a wholly owned subsidiary of HMC. Commencing in February, 1987, HMC will manufacture 30,000 motor vehicles for distribution by Mitsubishi Motor Sales of America, Inc. ("Mitsubishi America") under the Mitsubishi trademark. The vehicles sold to Mitsubishi America, however, will be substantially identical to the Hyundai Excel already being sold by Hyundai Motor America, except for some cosmetic differences, and will have HMC's own certification of compliance affixed to vehicles.

HMC requests your interpretation of FMVSS 208 as applies to Hyundai vehicles sold by both Hyundai Motor America and Mitsubishi America. Based on our own analysis, and after some informal preliminary discussions with NHTSA's Legal Department, HMC believes that Hyundai vehicles sold by HMC to Hyundai Motor America and Mitsubishi America must separately con- form to FMVSS 208. Thus, for example, HMC believes that FMVSS 208 requires that 10% of 1987 model Hyundai vehicles sold by Hyundai Motor America and 10% of 1987 model Hyunlai vehicles sold to Mitsubishi America must each contain passive restraint systems.

Please advise to the proper interpretation of FMVSS 208 as it applies to Hyundai vehicles sold to Hyundai Motor America and Mitsubishi America.

Very truly yours,

Mr. D. J. Henry Executive Vice President Meyer Products, Inc. 18513 Euclid Avenue Cleveland, Ohio 44112

Dear Mr. Henry:

This is in response to your November 16, 1976, letter concerning the removal of snow below assemblies prior to testing motor vehicles for conformity to Federal Motor Vehicle Safety Standard No. 301-75, Fuel System Integrity.

You have pointed out that a snow plow assembly includes components other than the part that actually contacts and moves the snow. You have requested confirmation of your interpretation that "no part of the snow plow assembly, including mounting components, was to be attached to a vehicle for purposes of (compliance testing ..."

That interpretation is incorrect. The presence or absence of snow plow components on a vehicle during compliance testing depends on whether the components are included in the vehicle's "unloaded vehicle weight". As the July 16, 1976, letter from Mr. Robert Carter of this agency to the jeep Corporation indicates, unloaded vehicle weight includes the weight of accessories that are not ordinarily removed from the vehicle when they are not in use. The statement in that letter that "snow plows" would be removed by the NHTSA prior to compliance testing can be amplified as follows: 1) A snow plow, i.e., the component of a snow plow assembly that actually contacts and moves the snow, will be removed. 2) Those other components of a snow plow assembly that, like the snow plow itself, are ordinarily removed when not in use will also be removed. 3) Those components which are not ordinarily removed from the vehicle when not in use will not be removed by the NHTSA prior to compliance testing. The agency will abide by a manufacturer's good faith categorization of accessories and components of accessories.

Sincerely,

Frank Berndt

Acting Chief Counsel

Mr. Frank A. Berndt Acting Chief Counsel National Highway Traffic Safety Administration 400 Seventh St., S.W. Washington, D.C. 20590

Dear Mr. Berndt:

Recently, our Sales Manager, Mr. Michael Groff, had the pleasure of meeting with Mr. Robrt N. Williams of your organization in regard to Federal Motor Vehicle Safety Standard 301-75, and Mr. Williams suggested that we address this letter to you.

Meyer Products, Inc. is a manufacturer of snow plows and salt spreaders for installation on or use in conjunction with motor vehicles, and we have been concerned about the effect of FMVSS 301-75 upon our business and that of our distributors.

In attempting to determine what, if any, action we should be taking with respect to FMVSS 301-75, we have examined a letter dated July 16, 1976, from Robert L. Carter, Associate Administrator for Motor Vehicle Programs of the National Highway Traffic Safety Administration, to Jeep Corporation, which states that snow plows "would be removed by the NHTSA prior to testing for conformity to Standard No. 301-75." As you will appreciate, a snow plow assembly consists of many components other than the moldboard that actually contacts and moves the snow. It has been our interpretation that no part of the snow plow assembly, including mounting components, was to be attached to a vehicle for purposes of teting the vehicle for compliance with FMVSS 301-75, and Mr. Groff has reported to us that our interpretation was orally confirmed by Mr. Williams.

In order to better asdsure our distributors that the installation of Meyer Products snow plows by them will not require them to retest the vehicles and will not result in their violating the National Traffic and Motor Vehicle Safety Act of 1966, as amended, or the regulations promulgated pursuant thereto, we would appreciate your sending us a leter confirming our understanding as recited above.

Since winter and the snow season have already arrived, it is imperative that we advise our distributors with respect to FMVSS 301-75 immediately, and we, therefore, request and thank you for your prompt response to this letter.

Sincerely yours,

MEYER PRODUCTS, INC.

TITLE: FMVSS INTERPRETATION

TEXT: This is in response to your letter of September 24, 1975, in which you ask whether it is permissible to test certain 1978 vehicles for compliance with Standard No. 301, Fuel System Integrity, with open vapor vent tube pressure relief valves.

The Federal motor vehicle safety standards do not specify the tests which you must perform. They do specify the conditions and procedures under which the National Highway Traffic Safety Administration (NHTSA) will conduct its compliance testing. S7.1.1 and S7.1.2 of Standard No. 301 specify that the vehicle's fuel system shall contain Stoddard solvent rather than fuel and, by implication, that the engine shall not be running. If, as you indicate, one consequence of the engine's not running is that a certain pressure relief valve in the vapor vent tube is closed, then that valve must remain closed during the NHTSA's compliance testing; the existing standard could not be interpreted otherwise. Although in an actual collision any rollover would probably occur immediately after the initial impact, in some accidents vehicle occupants would be trapped for some period of time after rollover. Therefore, we do not consider that this interpretation creates, as you suggest, an artificial condition by subjecting the fuel tank to a potential vapor pressure build-up during preparation for the rollover test.

Sincerely,

September 24, 1975

James B. Gregory -- Administrator, National Highway Traffic Safety Administration

Dear Dr. Gregory:

Re: Request for Interpretation in Relation to Conducting FMVSS 301-75 Tests with Proposed 1978 Evaporative Emission System

In preparing for compliance with 1978 California SHED evaporative emission requirements (presently under consideration by EPA for application in all areas), Ford Motor Company (Ford) is considering modifications to the fuel tank vapor venting system. At this time, Ford's primary design direction for certain of its 1978 vehicles is to incorporate a pressure relief valve in the vapor vent tube between the fuel tank vapor separator/rollover valve and the carbon canister (see Attachment).

When the engine is operating, this pressure relief valve will be open and the fuel tank will vent in a normal manner through the carbon canister. When testing according to the procedure set forth in FMVSS 301-75, the pressure relief valve would be closed, contrary to its normal open position when the engine is operating, and such closure would prevent venting of vapor from the fuel tank into the carbon canister. As a result, vapor pressure could build up within the fuel tank during FMVSS 301-75 testing, and indeed would do so if the fuel tank were exposed to elevated ambient temperatures during the substantial time period (in some instances several hours) required to ready the test vehicle for the rollover test following an impact test. If such pressure built up, it (taken together with the hydrostatic pressure of the Stoddard solvent in the tank) might force open the vacuum/pressure valve in the fuel tank cap and permit leakage through that valve (cap).

Such leakage would not occur in an accident involving a rollover because, in such a situation, vapor pressure would not build up in the fuel tank, and therefore, the vacuum/pressure valve in the cap would not open. Any rollover of the vehicle that may occur would happen immediately after the collision, before vapor pressure build-up. Hence the vacuum/pressure valve (cap) would remain closed after rollover. More particularly, just before the accident, the vapor vent tube pressure relief valve would be open, preventing vapor pressure build-up.

Accordingly, Ford proposes to perform tests relating to compliance with FMVSS 301-75 with the vapor vent tube pressure relief valve open, the better to simulate actual usage conditions. Before testing in this manner, Ford would appreciate receiving assurance from the Administration that it regards as appropriate the maintaining open of this pressure relief valve during rollover tests, and would conduct in that manner its rollover tests of those Ford vehicles equipped with such a valve.

As you are undoubtedly aware, in addition to design and development work, a test program required to obtain emission certification covers a period of many months. Therefore, since Ford has only a limited time in which to develop a 1978 evaporative emission system complying with the SHED requirements, an early response to this letter is urgently requested.

Respectfully submitted,

J. C. Eckhold -- Director, Automotive Safety Office, FORD MOTOR COMPANY

Dear Mr. Moore: This responds to your letter of July 31, 1995, wit respect to lens area requirements of amber turn signal lenses. You believe that 'by reducing the minimal area of the Amber Turn Signal light lens from 12 square inches to approximately 8 square inches or 6 square inches the U.S. would have more practical rules for U.S. Exports at no expense to Safety. You ask that, 'If NHTSA's Legal Council feels this error should be corrected through the Petitioning Process, I ask that this writing be considered a `Petition for Change of FMVSS; "108 Request''. Standard No. 108 contains two relevant regulations, on applicable to vehicles whose overall width is less than 80 inches, and one to those whose overall width is 80 inches or more. Under paragraph S5.1.1.26(a), the functional lighted lens area of a single turn signal lamp of either red or amber on a vehicle whose overall width is less than 80 inches shall be not less than 50 square centimeters. This is approximately 8 square inches. Therefore, no rulemaking is required to implement your recommendation. The standard that applies to turn signal lamps on vehicles whose overall width is 80 inches or more is SAE Standard J1395 APR85, incorporated by reference in Standard No. 108. Under its paragraph 5.3.2, the functional lighted lens area of a single turn signal lamp shall be at least 75 square centimeters, or approximately 12 square inches. Therefore, rulemaking is required to implement your recommendation. We are transmitting your letter to our Office of Safety Performance Standards for consideration as a petition for rulemaking to change the minimum lens area requirement for turn signal lamps on large vehicles from 75 to 50 square centimeters. On September 4, 1995, I determined that your letter met our procedural requirements for a petition. Accordingly, the Office of Safety Performance Standards will inform you not later than January 1, 1996, whether your petition has been granted. If you have any questions, you may refer them to Taylor Vinson of this Office (202-366-5263). Sincerely, John Womack Acting Chief Counsel";

Could you please be so kind and answer me some questions about the FVMSS 108 and the CAC Title 13, Article 9.

The amended FMVSS 108 says: S7.7.3 When a headlamp system is tested in a laboratory, the range of its vertical aim shall not be less than +/- 4 degrees ... S7.7.4 When a headlamp system is tested in a laboratory, the range of its horizontal aim shall not be less than +/- 2.5 degrees ... CAC says: The range of adjustment from the specified aim the lamp shall be at least +/- 4 degrees in both the vertical and horizontal directions. So my questions are: Does this mean that our headlamps still must have an adjustment range of +/- 4 degrees in horizontal direction, although the FMVSS 108 has been changed? Is it possible that the CAC meanwhile has been amended according to the FMVSS 108? Is it true that the CAC doesn't differ between auxiliary lamps and headlamps (in opposite to the FMVSS 108 that is only valid for headlamps)? Thanking you very much in advance for your actions.
