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 Sir:

At the request of the office of the Honorable Peter Peyser, M.C., we are writing this letter to you to explain the significance of certain items of information molded on the sidewall of new tires.

Part 574, Tire identification and recordkeeping (49 CFR 574), requires that each new tire to be sold in the United States have a serial number molded on one of its sidewalls. That number identifies the tire's manufacturer, date of manufacture, and size. This information is designed to ensure the proper identification of all tires subject to a recall by the manufacturer for correction of a safety-related defect or of a failure to comply with a safety standard. The serial number is not a guarantee of quality or of compliance with any safety standard.

Each new tire is also required by Federal Motor Vehicle Safety Standards Nos. 109, New pneumatic tires, and 119, New pneumatic tires for vehicles other than passenger cars (49 CFR 571.109 and 571.119), to have the symbol "DOT" appear on one of its sidewalls. This symbol is a certification by the tire's manufacturer that the tire fully complies with all requirements of the applicable safety standard. The symbol does not guarantee the quality of a tire in areas of performance unregulated by the safety standards.

Neither the serial number nor the DOT symbol constitute a representation that a tire is free from any safety-related defect.

If you have any questions regarding these matters, please contact me.

Sincerely,

Frank Berndt Chief Counsel June 2, 1982

Dear Mr. Woolley:

This is in reply to your letter of July 8, 1982, to Mr. Vinson of this office asking what you must do pursuant to Federal regulations as a manufacturer of taillamps for boat trailers.

The Federal motor vehicle safety standard you must consider is Standard No. 108, Lamps, Reflection Devices, and Associated Equipment. (Title 49, Code of Federal Regulations, S571.108) Under its terms, every vehicle taillamp must meet the requirements of SAE Standard J585e Tail lamps (Rear Postion Lamps), September 1977, and the SAE materials referenced in J585e, except that paragraph S4.1.1.12 of Standard No. 108 establishes alternative photometric equipment. The standard does not establish per se a minimum lens area for a taillamp. However, a vehicle manufacturer is required to ensure that when a tail lamp is installed, "the lamp must provide an unobstructed projected illuminated area of outer lens surface, excluding reflex," at least 2 square inches in extent, measured at 45 deg. to the longitudinal axis of the vehicle" (paragraph 4, J585e).

As a manufacturer, you are required to certify compliance of each taillamp with all applicable Federal motor vehicle safety standards, which may be by labelling the lamp with the symbol DOT, or by a statement on the lamp or on its shipping container (paragraph S4.7.2, Standard No. 108). You are also required to file an identification statement with the agency (49 CFR Part 566). In the event any taillamp fails to comply with Standard No. 108, or incorporates a safety-related defect, you must notify purchasers and remedy the problem in the manner specified by 49 CFR Part 577, after filing a report with the agency (Part 573).

You may obtain a copy of all Federal requirements by sending a check for $8 to the Superintendent of Documents, U.S. Government Printing Office, Washington, D.C. 20402 and asking for "Title 49 Code of Federal Regulations - Parts 400 to 999, revised as of October 1, 1981."

For further information on the SAE materials, write "Technical Division, SAE, 400 Commonweath Drive, Warrendale, PA 15096 (or call 412-776-4841). In addition to J585e, you will need copies of J575e Tests for Motor Vehicle Lighting Devices and Components, August 1970; J576d Plastic Materials for Use in Optical Parts Such as Lenses and Reflection of Motor Vehicle Lighting Devices, June 1976; and J578c Color Specification for Electric Signal Lighting Devices, June 1977.

JUL 26 1982

Mr. Bernard S. Horton 100 Memorial Drive Cambridge, MA 02142

Dear Mr. Horton:

This responds to your recent letter regarding the roof crush requirements of Federal Motor Vehicle Safety Standard No. 216. You ask why convertibles are excluded from the requirements of the standard, yet the BMW 318 which has a "targa" roof is not excluded.

Convertibles were excepted from Safety Standard No. 216 when the standard was first issued in 1971 because it was impossible for most convertibles to comply with the requirements. The legislative history of the National Traffic and Motor Vehicle Safety Act of 1966 (15 U.S.C. 1381, et seq.), which authorizes the issuance of our safety standards, clarifies that Congress did not intend for the safety standards that would be issued to effectively preclude any type of existing motor vehicle. If no exception had been provided, the requirements of Safety Standard No. 216 would have caused the production of convertibles to cease. For this reason alone, they were excepted from the requirements.

The agency has limited the convertible exception to vehicles for which it is truly impractical to comply. While our regulations do not include a formal definition of "convertible", the agency has stated that it considers a convertible to be a vehicle whose "A" pillar or windshield peripheral support is not joined with the "B" pillar (or rear roof support rearward of the "B" pillar position) by a fixed, rigid structural member. Therefore, passenger cars equipped with a "sun roof", "hurst hatch roof" or "targa roof" do not qualify as convertibles, because they have a fixed, rigid structural member in the described location. This interpretation applies, moreover, whether the rigid structural member joining the "A" and "B" pillars is a hidden reinforcing component or whether the structural member is part of the exterior roof panel.

I am sorry that you are unable to obtain the BMW 318, but this is primarily due to the fact that the manufacturer has chosen not to bring this model into compliance with Safety Standard No. 216. As you probably know, there are other models with "targa roofs" and "hurst roofs" that are in compliance with the standard and currently in use.

You also mention the fact that many vehicle custom shops cut one or more panels from vehicles to make them into convertibles or "targas". You state that there seems to be no prohibition to this. There are certain prohibitions, however. Section 108(a)(2)(A) of the Vehicle Safety Act specifies that 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 in compliance with a motor vehicle safety standard. This means that custom shops cannot cut panels from a used vehicle's roof if such operation would impair the vehicle's compliance with Safety Standard No. 216. Failure to observe this prohibition could result in civil penalties up to $1,000 for each violation. Please note, however, that the custom shops are not precluded by this section from totally removing a vehicle roof, thereby converting the vehicle into a convertible. The prohibition does not apply to such a conversion since the vehicle would not have had to comply with Standard No. 216 if it had originally been manufactured as a convertible.

I realize that these various distinctions may be confusing. If you have any further questions, please contact Hugh Oates of my staff at 202-426-2992.

Sincerely,

Frank Berndt Chief Counsel

Frank Berndt, Esq. Office of the Chief Counsel NATIONAL HIGHWAY TRANSPORTATION SAFETY ADMINISTRATION 400 7th Street S.W. Washington, D.C. 20590

Dear Mr. Berndt:

I am trying to determine why one automobile or another might or might not meet Standard 216 or some other standard for roof crush resistance.

Specifically, I have been interested in buying an Americanized version of a BMW 318 cabriolet. I am told that it can't be imported here because it doesn't meet roll-over or roof crush requirements. Yet, as indicated by the enclosed article, convertibles are becoming popular again. They, at least the soft top ones I've seen, have no roof crush resistance.

By my way of thinking, a cabriolet, which is often called a "targa" because it has a section of roof which can be removed, and perhaps a drop down back window behind a bar, should be safer than a soft top convertible. In fact, customizing shops offer the cutting of one or more panels from the many makes of cars to make them into convertibles or "targas". There seems to be no prohibition to this.

Can you clarify why the BMW Cabriolet, in the light of what is on our roads, seems to be singled out as unacceptable?

Thank you very much for your help.

The National Highway Traffic Safety Administration only requires that all vehicles be manufactured in compliance with the applicable motor vehicle safety standards. We have no requirement, nor do we know of any other Federal regulation, that would prevent Mr. Robinson from purchasing just the cab and chassis of a vehicle that he desires. When he adds his own utility body to the cab and chassis, he would become the final-stage vehicle manufacturer and would be required to certify that the completed vehicle complies with all applicable Federal safety standards. I am enclosing copies of the regulations pertinent to such an operation.

Dear Senator Pressler:

This responds to your July 23, 1982, letter enclosing correspondence from your constituent, Mr. Clyde Pritchard. Mr. Pritchard questioned the applicability of the National Highway Traffic Safety Administration's Standard No. 121, AirBrakes, to certain "heavy hauler trailers." He also questioned a portion of that standard that indicated that manufacturers of some vehicles may comply with the standard or, alternatively, with Part 393.43 of the regulations of the Bureau of Motor Carrier Safety (BMCS).

Only some types of heavy hauler trailers must comply with Standard No. 121. The applicability section of the standard states that a vehicle with a width in excess of 102 inches or a heavy hauler trailer with a gross vehicle weight rating (GVWR) in excess of 120,000 pounds need not comply with any of the requirements. Therefore, any vehicle designed by Mr. Pritchard falling within these categories would be excepted from the standard. A heavy hauler trailer with a width less than 102 inches and a GVWR less than 120,000 must comply with the standard.

Mr. Pritchard appears most interested in the specific requirements for parking brakes on heavy hauler trailers. Paragraph S5.6 of Standard No. 121 states that heavy hauler trailers shall comply with the requirements of Standard No. 121 for parking brakes or, alternatively, with BMCS regulation 393.43 for breakaway. Accordingly, the manufacturer of such a vehicle has the option of complying with either provision; parking brakes under Standard No. 121 or the breakaway and emergency braking section of the BMCS regulation. The citation in Standard No. 121 to BMCS regulation 393.43 is correct. The agency did not intend to permit optional compliance with BMCS regulation 393.41 as suggested by Mr. Pritchard. That regulation does not require separate brakes on trailers which the agency has always deemed necessary.

I hope this clarifies the air brake issue for your constituent. Please contact me if you need additional information.

TEXT: This is in reply to your letter of July 1, 1982, to Mr. Vinson of this office with regard to your "new motorcycle lighting system" and asking about possible conflicts with the Federal motor vehicle safety standards.

Your device is an "aftermarket accessory" light which may be mounted to a motorcycle helmet, and which is integrated by a cord into the motorcycle's headlighting system, providing an auxiliary beam of light in conjunction with the beam of light projected by the main headlamp.

Federal Motor Vehicle Safety Standard No. 108, Lamps, Reflective Devices, and Associated Equipment, is the standard on vehicle lighting and lighting equipment while Standard No. 218, Motorcycle Helmets, is the other standard of relevance. Neither standard directly addresses an aftermarket device such as yours and as your lamp is intended to be installed by the helmet owner, it does not appear to conflict with any other regulatory prohibition of this agency. It would, therefore, be subject to regulation by the individual States in which the device is worn.

We see nothing in your correspondence that legally qualifies as "sensitive proprietary information", and our interpretation will be given its usual circulation.

SINCERELY,

Taylor Vincent Chief Counsel DOT/NHTSA

July 1, 1982

Dear Sir;

Enclosed you will find a description of a new motorcycle lighting system and a copy of the utility patent protecting it.

At the suggestion of Dr. Carl Clark, NHTSA inventor contact, at our meeting of 4/15/82 at DOT, I am contacting you in order to clarify any possible areas of conflict with existing Federal regulations that this system presents.

One possible conflict that was discussed concerned Motor Vehicle Safety Standard Number 218 with regard to motorcycle helmets. Paragraph S5.5 states that "Rigid projections outside any helmet's shell shall be limited to those required for operation of essential accessories, and shall not protrude more than 0.19 inch." As evidenced by the enclosed descriptive material. the system clearly employs a detachable helmet mounted light source whose housing projects substancially beyond the 0.19 inch limit.

This helmet light is an aftermarket accessory which is detachably installed by the operator by means of Velcro- like, 3M Dual Lock self adhesive fasteners. This mounting system is to be engineered so as to allow the helmet light accessory to shear away from the helmet surface upon application of a force substantially less than that which might cause injury. Indeed, the only somewhat permanent projections applied to the helmet itself are the three self adhesive strips of Dual Lock fastener which engage three complimentary strips on the underside of the helmet light. These strips don't project more than 0.19 inch.

As there are not currently any standards directly regarding a helmet mounted light as described, which integrates with the standard lighting system, and may be mediated by a photo electric dimming system to prevent the blinding of oncoming drivers, I would appreciate your opinion as to whether standard headlamp regulations apply.

Dr. Clark has seen the product and is most aware of the properties it exhibits. Any questions you may have may be directed either to Mr. Clark or this office. Your opinions on the above points are of significant commercial interest to us, and your earliest consideration would be appreciated. Please treat everything exclusive of the patent itself as sensitive proprietary information.

Dear Mr. Clark:

This responds to your March 23, 1982, letter asking whether it is permissible to install side-facing seats in school buses designed to transport the handicapped. The answer to your question is yes.

Standard No. 222, School Bus Passenger Seating and Crash Protection, specifies the requirements for school bus passenger seats and, in general, requires those seats to be forward facing. However, the definition of "school bus passenger seat" in section S4 of the standard excludes seats installed to accommodate handicapped or convalescent passengers as evidenced by installing those seats longitudinally. Therefore, seats installed in the buses to which you refer in your letter need not comply with the school bus seat requirements if they are designed to accommodate the handicapped and are side facing.

We caution, however, that side-facing seats afford less protection than forward facing seats. Accordingly, only those seats necessary to accommodate the handicapped should be altered in this manner.

You have asked whether the vehicle would comply if the lower mounted set were removed and an amber reflex reflector placed on each side of the fender as far forward as practicable.

The answer is yes. The mounting height of 81 1/2 inches does not exceed the limit of 83 inches imposed by Table II of Standard No. 108. In addition, the lamps appear to meet the two further requirements that they be located as far apart as practicable and at the same height.

Subject: Federal Motor Vehicle Safety Standard Number 108 Lamps, Reflective Devices and Associated Equipment

Gentlemen:

Enclosed please find two photographs of a 1982 Kenworth, Model W900. You will note from the photographs that two sets of turn signals are on the vehicle, one set on the hood and another set on the bottom of the mirror brackets.

On the vehicle shown, which is typical of the Model, the center of the fender mounted signals are approximately 58 1/2" above the road surface and approximately 83" apart.

The center of the mirror mounted turn signals are approximately 81 1/2" above the road surface and approximately 110" apart.

Our question concerns Federal Motor Vehicle Safety Standard Number 108(571.108), specifically, Table II, "Location of Required Equipment", "Turn Signal Lamps". Considering the dimensions above, would the vehicle be in conformance with the Standard if only the mirror mounted turn signals were installed on the vehicle and an amber reflex reflector placed on each side of the fender as far forward as practicable?

We would appreciate your consideration and reply to this matter at your earliest opportunity.

Yours truly, Ronald E. DeVolder -- Vice President
