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.

TEXT: This is in reply to your letter of January 30, 1978, to Ms. Joan Claybrook, Administrator of the National Highway Traffic Safety Administration (NHTSA), concerning the seat belts in your Cougar automobile.

Your original letter of December 12, 1977, to Secretary Brock Adams, complaining about the seat belts in your automobile has been answered. A copy of our reply is enclosed to this letter and is still relevant to your problem.

As long as the lap-shoulder belt intersection is not less than 6 inches from the vertical centerline of the driver, any other location that is confortable and easy to use is allowable. We suggest that you again contact your dealer to determine if the belt arrangement can be modified to be better suited to your condition and yet have the belt configuration remain within the NHTSA requirements.

SINCERELY,

January 30, 1978

Honorable Joan Claybrook Department of Transportation

Dear Miss Claybrook:

I have been in correspondence with the Ford Motor Company concerning the inadequacies of the seat belts in their new cars, and especially the Cougar.

I am enclosing copies of correspondence that I have had with the Ford Motor Company and the Department of Transportation, and this latter has not been answered.

The present seat belt arrangement is almost impossible for a person of my age to use. If the attachment on the right side of the driver were six inches longer it would be easy to use. As it is, when I drive around town I am not using a seat belt, although I would prefer to use one. When I take longer trips, I use it and, if my wife is along, I have her assistance in attaching it. If she is not along, I struggle and struggle until finally I get it attached.

It is of interest to me that the Ford Motor Company blames the Department of Transportation for this inadequacy. I just can't believe it. If it is the fault of the Department of Transportation I hope the Department will correct it.

If the Department of Transportation can't help in this matter, then I plan to take it up with some member of Congress.

As you well know, we got rid of the interlock system. I think this can be corrected too.

VERY TRULY YOURS, Emil M. Mrak

The Honorable Brockman Adam The Secretary of Transportation

Dear Mr. Adams:

Sometime ago I wrote the Ford Company complaining about the inaccessibility of the short portion of the seat belt to a person who is up in years. I pointed out that because of the extreme difficulty of hitching these up, more and more people are failing to use seat belts. Furthermore, the twisting and squirning required could very well result in backbone injuries to elderly people.

I was astounded to receive a letter from the Ford Company indicating that the Federal Standards required such a belt. This is hard for me to believe. In any event, I would appreciate knowing if what they told me is the truth, and if it is, then, the truth, I would strongly recommend that this requirement be revised. If it is not a requirement, then I think the Ford Company should be told to take the blame off the Department of Transportation.

If Congressional help is needed to make such a change, I would be glad to pursue it.

I am enclosing copies of my letter to Mr. Wilson of the Ford Company and also his reply, which as (Illegible Words) astonished me.

VERY TRULY YOURS, Emil M. Mrak

TITLE: FMVSS INTERPRETATION

TEXT: This responds to your September 20, 1977, letter asserting that the Wisconsin requirement for minimum seat spacing does not conflict with the Federal requirement for maximum seat spacing found in Standard No. 222, School Bus Passenger Seating and Crash Protection.

Section 103(d) of the National Traffic and Motor Vehicle Safety Act of 1966 (the Act) (15 U.S.C. 1381 et seq.) specifies that no State shall have in effect a safety standard concerning an aspect of performance regulated by a Federal safety standard, unless the State standard is identical. The Act provides a limited exception to the above where a State or local municipality has a requirement which applies only to vehicles purchased for their own use and which imposes a higher standard of performance. Both Standard No. 222, which regulates maximum seat spacing, and the Wisconsin standard, which regulates minimum seat spacing, regulate the same aspect of performance. This position is supported by our statements in Notice 5 of Standard No. 222 (41 FR 4016) which expressed the opinion that seat spacing is the regulated aspect of performance (copy enclosed). Since your State standard is not identical to the Federal standard, it is the opinion of the NHTSA that it is preempted.

You should note that although you are not permitted to impose this State standard on all vehicles used in your State, the Federal government does not preclude you from purchasing any buses for your own use from among the several designs now in production. You could, therefore, purchase only those vehicles that afford you the minimum knee space you desire. You should note further that purchase for your own use has been interpreted to mean purchased by a contractor under contract to provide transportation for school children.

September 20, 1977

Joan Claybrook, Administrator NHTSA Office of the Administrator

Dear Ms. Claybrook:

Re: Letter to you from Mr. Robert Kurre, Wayne Corporation Date September 2, 1977

The State of Wisconsin stoutly defends it's position that there is no point of conflict between the FMVSS 222 relating to seat spacing and the Wisconsin Administrative Code, MVD 17.

FMVSS dictates a maximum space permitted (for compartmentalization) for persons riding in school buses. The Wisconsin rule states a minimum distance that is permissible.

The engineering staff at Wayne Corporation was aware of these two non-conflicting standards as of February 23, 1977. It appears to us that this should have been adequate lead time to design and test seats that can meet both the federal and state standard.

To emphasize this point, we have been advised by one manufacturer of school bus bodies that they are meeting both federal and Wisconsin standards on buses manufactured after April 1, 1977. It is the State of Wisconsin contention that it is merely a matter of proper design by the manufacturer to meet both requirements.

The Wisconsin standard was developed because of the concern for adequate knee room in the seats. The federal standard has no minimum knee room, therefore, if a manufacturer wished to have, for instance only 20 inches of knee room, he could so produce a bus and not be in conflict with the federal standard. This is what we have prevented by the implementation of our minimum spacing measurement. We have observed buses built to less than the 24 inch minimum spacing and they are unacceptable for the cross section of pupil transportation in Wisconsin.

To carry this a bit further, the State of Wisconsin subscribes to the proposal that the federal government interpret the 20 inch measurement from the seating reference point be made at the closest point between the seat back rather than have this at the widest point.

We believe Mr. Kurre is in error by stating that the State of Wisconsin has a standard in conflict with a federal standard. We further believe that our 24 inch measurement is the extreme minimum that is necessary for transportation of any school children in Wisconsin

If I can supply you with additional information in this matter, please advise.

You first ask whether these buses must be painted yellow and have school bus lighting and markings. The answer to your question is yes. Any vehicle that transports 10 or more students to or from school or related events is a school bus and must have the painting, marking, and lighting of a school bus.

Your second question is whether smaller school buses (vans) are permitted to have van-type seats or must comply with the requirements of Standard No. 222, School Bus Passenger Seating and Crash Protection. A vehicle that transports 10 or more students must comply with all of the Federal school bus regulations, including the seating standard.

The question you raised was whether odometer disclosure statements have to be executed under section 580.4 and retained under section 580.7 of title 49, Code of Federal Regulations when the vehicle involved is a salvage vehicle.

If the vehicle is repairable and will subsequently be used as a motor vehicle, disclosure would have to be made. Likewise, the disclosure statements would have to be maintained if section 580.7 is adopted as a final rule. However, if the vehicle is so badly damaged that it cannot be returned to the road, it will have ceased to be a motor vehicle for purposes of the regulations. Disclosure would therefore not be required.

TITLE: FMVSR INTERPRETATION

TEXT: This responds to your February 23, 1978, letter asking whether the National Highway Traffic Safety Administration's (NHTSA) interpretation concerning the registration of passenger car tires can be applied to the registration of truck tires. In that interpretation, the NHTSA stated that it was permissible for a tire dealer to allow the tire purchaser to fill out the tire registration form and hand it back to the dealer.

The NHTSA's interpretation is applicable to both truck and passenger car tires. A truck tire dealer may permit a purchaser to fill out the required information rather than completing the registration form himself. However, this all must occur at the point of sale of the tire. The registration forms for both passenger car tires and truck tires are not permitted to be taken home or shipped with the tires to be completed by the purchaser and subsequently returned or mailed to the dealer. This would impair the benefit of mandatory tire registration and make it a voluntary program. This is not the intent of the regulation, and the NHTSA would not consider such a registration program to be in compliance with the tire registration regulation.

SINCERELY,

NATIONAL TIRE DEALERS & RETREADERS ASSOCIATION, INC.

Roger Tilton National Highway Traffic Safety Administration

Dear Mr. Tilton:

As you know, NHTSA has issued a interpretation of the regulations regarding tire identification and record keeping, which permits the tire dealer to hand to the consumer of passenger tires a form which the consumer may fill out at the dealers place of business.

Since a similar type of problem now exists in the sale of truck tires the question has been raised on registration there also.

It it permissible for a tire dealer, selling to a trucker, to give the trucker a form to fill out and return to the individual dealer? In some cases truck tires are shipped directly from the manufacturer to the trucker and the dealer may not have even a direct contact on every shipment.

Letting the cards accompany the tires or providing the registration cards to the trucker might be helpful. We would appreciate some guidance on this so we may advise our membership.

Gentlemen:

Euro-Tire, Inc. is a retailer of several brands of passenger car tires.

Because of the nature of our operation, the registration of D.O.T. tire identification numbers as required by law has become very time consuming and costly to us.

Since our operation is fully automated, it would be advantageous to us to record the required information for the various brands of tires we sell on one universal form rather than on the several different forms provided by our supplier-manufacturers or their agents.

Attached is a photocopy of the form we designed for this purpose. The sample typewritten information, namely, customer name and address, date of sale and brand name, will be computer printed.

We believe that our form meets all the informational and dimensional requirements of NHTSA's "universal format" and that it complies substantially with the layout of the "universal format".

We would appreciate your reviewing our form and advising us promptly as to whether or not is is an acceptable substitute for the several different forms provided by our suppliers for registration purposes.

Dear Mr. Abbott:

This is in response to your letter dated June 27, 1978, asking whether fog lamps mounted to the surface of a vehicle bumper are removed prior to testing for compliance with Part 581, Bumper Standard.

Vehicles subject to the requirements of Part 581 must comply with the protective criteria of section 581.5(c) (49 CFR 581.5(c)) when tested under the conditions stated in section 581.6 (49 CFR 581.6). The test conditions make no provision for removal of fog lamps prior to testing. As was the case under Federal Motor Vehicle Safety Standard 215, Exterior Protection, the Part 581 test procedures provide for removal only of trailer hitches before testing. With the added exception of license plate brackets, excluded from the requirements of Part 581 by interpretation (42 FR 24056; May 12, 1977), other equipment (including fog lamps) attached to the bumper system prior to sale of the vehicle to its first purchaser must meet the damage limitations of the standard.

Dear Mr. Levin:

Cars & Concepts, Inc. is preparing a prototype Dodge Omni "Rally" for a 1980 model year production program. It is proposed that Chrysler Corporation ship completed vehicles to one of our facilities where we would attach certain pieces of equipment comprising the "Rally" package. The vehicles would then be shipped back to Chrysler for distribution through their normal channels. Included in the "Rally" package is a pair of Cibie C-95 white fog lamps. These would be made inoperable for highway use by means of an easily removable fuse mounted to the instrument panel. The lamps would be mounted to the top surface of the bumper (to comply with certain state regulations) and closely enough to the vehicle centerline to avoid the normal beam path of the headlights. To avoid contact with the grille when the bumper is fully compressed, it will be necessary to mount the lamps close to the bumper face placing them in potential danger of being damaged in a 5 mph pendulum test. It is our understanding that under the provisions of FMVSS #215 such items were routinely removed before testing. We are concerned that the status of accessory lighting would change under FMVSS part 581 and would like a clarification of this.

Thank you for your assistance in this matter.

Mr. Robert J. Shirock Safety Director U.S. Army Tank-Automotive Material Readiness Command Department of the Army Warren, Michigan 48090

Dear Mr. Shirock:

This is in reply to your letter of November 13, 1978, to the Administrator questioning whether certain trucks procured by your Command comply with paragraph S4.5.4 of Federal Motor Vehicle Safety Standard No. 108.

That paragraph states "The stop lamps on each vehicle shall be activated upon application of the service brakes." You wrote that "when the hazard warning lights are activated the stop lamp cannot be activated upon application of the service brakes." The system you describe would be in compliance with Standard No. 108, if the stop lamps and signal lamps are optically combined, for the following reasons. Paragraph S4.4.1 allows combination of a stop lamp with a turn signal lamp (which provides the hazard warning signal). Paragraph 4.2 of SAE Standard J586c Stop Lamps, August 1970 (incorporated by reference in Standard No. 108 as the operative standard for stop lamps) requires that "When a stop signal is optically combined with the turn signal, the circuit shall be such that the stop signal cannot be turned on in the turn signal which is flashing."

This, of course, means that in a combination lamp the stop signal cannot be given while the hazard warning signal is being operated. If the Army deems it desirable it could require a different circuitry in combination lamps by which the stop lamps and hazard warning signal lamps could operate simultaneously, as military vehicles need not conform to Federal safety standards (49 CFR 571.7(c)).

Because several jurisdictions require slow-moving vehicles to use the hazard lamps while in motion, I am asking our Office of Rulemaking to review this prohibition. Thank you for bringing this matter to our attention.

Reference is made to FMVSS 108, paragraph S4.5.4.

Referenced paragraph states "The stop lamps on each vehicle shall be activated upon application of the service brakes."

Inspection of the lighting system in some commercial trucks recently procured by this Command disclosed that when the hazard warning lights are activated the stop lamp cannot be activated upon application of the service brakes.

While it is recognized that the primary purpose of hazard warning lights is to warn approaching traffic of a disabled vehicle, several states require the use of hazard warning signal for slow moving vehicles, i.e, NY Thruway, and Pennsylvania Turnpike. Application of the service brakes under this condition would not activate the stop lamps to warn following traffic.

Request this office be provided the DOT position as to whether or not the system described above meets the requirements of FMVSS 108, S4.5.4.

Dear Mr. Bally:

We understand that you are interested in an interpretation of the relationship of a rear lighting system, developed by your client Mr. Leno Bevilacqua, to Federal motor vehicle lighting requirements. As you described this device in your letter of September 29, 1978, to the Nevada Department of Highways:

"The device will project a green light for the vehicle which would be in a constant or accelerated speed, a yellow light for the vehicle in a decelerated moving state and a red light for the vehicle which would be stopping."

Federal Motor Vehicle Safety Standard No. 108, Lamps, Reflective Devices, and Associated Equipment, (49 CFR 571.108) neither requires nor expressly prohibits a lighting device of this nature as original equipment on motor vehicles. One section of the standard, however, S4.1.3, prohibits the installation of all original lighting equipment not mandated by the standard "that impairs the effectiveness of lighting equipment required by this standard." While we make no judgment with respect to Mr. Bevilacqua's 18-inch long 1 1/2 inch high rectangular device, I think it important to note that the agency's research into rear green signal lights indicate that there may be disadvantages rather than advantages to such a lighting system. One major disadvantage is the problem of confusing the unfamiliar colored rear lamps in urban environments having multicolored lights.

Standard No. 108 does not cover this device as an aftermarket item, and it would therefore be subject to regulation by the individual States.
