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. George J. Aumond
President
Intec Industries, Inc.
1025 S. Linwood Ave.
Santa Ana, CA 92705

Dear Mr. Aumond:

This responds to your request for an interpretation whether your company must assign new vehicle identification numbers (VINs) to used trailer chassis, under the facts described in your letter. If the trailers are modified in accordance with NHTSA's regulations on combining new and used components in trailer manufacture, the trailers would be considered used and the VIN assigned to each trailer may be retained.

Your letter states that Intec Industries is in the process of redesigning 40-foot shipping container chassis to "accommodate new laws pertaining to distribution of weight on bridges." You describe the changes as follows:

The modification is accomplished by modifying an existing 40' straight frame chassis, to accommodate one 20' container, with a 48,000 pound load, or, two empty 20' containers, or one 40' or 45' container with 48,000 pound loads. When completed, only the rear 10' of the 40' frame is not used. The compressed length of finished unit is 30'-0". All braking systems, wheels, tires, accumulation tanks, and fifth wheel components, are essentially left intact, and are incorporated into the new design.

In a telephone conversation with Dorothy Nakama of my staff, you stated that if possible, your company would like to retain the assigned VIN on the modified trailers. You further stated that after the changes are made, the gross vehicle weight rating and the gross axle weight ratings of each trailer chassis will remain the same. The distance between the wheels (on the same side of the vehicle) will be adjusted, so that the trailer chassis' load distribution will be in line with new bridge weight requirements.

NHTSA's regulations at 49 CFR 571.7(f) Combining new and used components in trailer manufacture apply to your company's trailer modifications. That regulation provides:

When new materials are used in the assembly of a trailer, the trailer will be considered newly manufactured for purposes of [the Federal Motor Vehicle Safety Standards] unless, at the minimum, the trailer running gear assembly (axle(s), wheels, braking and suspension) is not new, and was taken from an existing trailer -

(1) Whose identity is continued in the reassembled vehicle with respect to the Vehicle Identification Number; and

(2) That is owned or leased by the user of the reassembled vehicle.

Thus, if the trailers are modified under the conditions described in Section 571.7(f), the trailers would be considered used, and Intec Industries may continue to use the assigned VINs on the modified trailers.

Please note that in the modification process, your company must ensure that the certification labels (assigned pursuant to 49 CFR Part 567 Certification) remain on the trailers. Additionally, in order to avoid a violation of 49 U.S.C. 30112(b), when modifying the trailers, your company must not "knowingly make inoperative any part of a device or element of design installed on or in [those vehicles] in compliance with an applicable motor vehicle safety standard..."

I hope this information is helpful. If you have any further questions, please contact Dorothy Nakama at this address or at (202) 366-2992.

John Womack

Post Office Box 934
Des Moines, IA 50304-0934

Dear Mr. Allen:

Please pardon the delay in responding to your letter to this office in which you asked whether the processing equipment that your company produces for the aggregate industry is excluded from the antilock brake system (ABS) requirement of Federal Motor Vehicle Safety Standard (Standard) No. 121, Air brake systems. The answer is yes.

You stated that some of the equipment that you manufacture is wheel-mounted for ease of transport from the factory to the customer and by the customer between job sites as required. You explained that the equipment is not load-carrying since the equipment is the load. You stated that the equipment was designed to spend its entire life at mining or quarry sites and would probably spend less than one percent of its life on the road. You enclosed brochures depicting and describing the various lines of equipment that you manufacture, specifically alluding to your wheel-mounted portable Sand Washing-Classifying machine, wheel-mounted portable Sand Washer-Classifier-Dehydrator, and your portable wheel-mounted Log Washers.

Chapter 301 of Title 49, U.S. Code (hereinafter Safety Act) authorizes this agency to establish Federal motor vehicle safety standards applicable to new motor vehicles and new items of motor vehicle equipment. The Safety Act defines "motor vehicle" as:

[A] vehicle driven or drawn by mechanical power and manufactured primarily for use on the public streets, roads, and highways, but does not include a vehicle operated only on a rail line.

49 U.S.Code 30102(a)(6).

In reviewing the information you provided, including your brochures, it is our opinion that the aggregate equipment that you described and as depicted in your brochures are not motor vehicles within the statutory definition. They are obviously designed to be used primarily off-road and although they are portable and therefore capable of being transported on-road from the factory to the customer and by the customer from one job site to another, their on-road use is only incidental and not the primary purpose for which the equipment was manufactured. Not being motor vehicles, therefore, your wheel-mounted items of equipment, such as your Sand Washing-Classifying machines, Sand Washer-Classifier-Dehydrators, and Log Washers are not required to comply with the Federal motor vehicle safety standards, including Standard No. 121.

Standard No. 121 (copy enclosed), requires trailers, among other vehicles, equipped with air brake systems to be equipped with ABS. Excluded from that requirement, however, is

Any trailer that has an unloaded vehicle weight which is not less than 95 percent of its GVWR.

49 CFR 571.121, paragraph S3(f).

Your information would indicate that the equipment in question would also meet this exclusion since, as mentioned above, the equipment is the load. Accordingly, even if your equipment were considered motor vehicles, they would still be excluded from the ABS requirement under this provision.

I hope this information is helpful to you. Should you have any further questions or need additional information, feel free to contact Walter Myers of my staff at this address or at (202) 366-2992, fax (202) 366-3820.

Purchasing Manager
Redneck, Inc.
2100 N. West By-Pass
Springfield, MO 66803


Dear Mr. Maison:

This replies to your letter of August 30, 1996, to Taylor Vinson of this Office, asking for an interpretation of the conspicuity requirements of Motor Vehicle Safety Standard No. 108.

You write that "the by-laws read that DOT-C is for the vehicles and trailers under 25,999 pounds require for that class. We would like to use these reflectors also for the DOT- C2, for the use on vehicles and trailers over 26,000 pounds."

We do not know the "by-law" to which you refer. Paragraph S5.7 of Standard No. 108 applies to all trailers of 80 or more inches overall width, and with a GVWR over 10,000 pounds. It does not distinguish between those over and under 26,000 pounds. Therefore, a trailer with a GVWR of 26,000 pounds must meet the same requirements of paragraph S5.7 as a trailer with a GVWR of 10,001 pounds.

We understand that you have discussed your problem with Pat Boyd, one of this agency's rulemaking engineers, and that your questions are: "What is the difference between DOT-C and DOT C-2" and "Does a reflex reflector have to be 2 inches wide, like reflective tape?"

Paragraph S5.7 permits a manufacturer to choose either reflex reflectors or reflective tape as the way to conform to the conspicuity requirements of Standard No. 108. "DOT-C" is the marking required for reflex reflectors, and is the reflector manufacturer's certification that the reflectors meet Standard No. 108 (Paragraph S5.7.2.3). "DOT- C2" is the marking required for reflective tape which has a width of not less than 50 mm (2 inches) and is the reflective tape manufacturer's certification that the tape meets Standard No. 108 (Paragraphs S5.7.1.3(d) and S5.7.1.5). Standard No. 108 does not require that reflex reflectors have a minimum width. Reflex reflectors are rated by the total light return per reflector, but reflective tape is rated by the light return per unit area. Standard No. 108 requires that one reflex reflector, meeting the DOT-C specification, have the same total light return as 100 mm of reflective tape meeting the DOT-C2 specification. We have seen reflex reflector bars 300 mm long certified to meet the DOT-C specification for each 100 mm segment. Standard No. 108 permits the use of these products even though they are only about 1 inch wide because they provide the same photometric performance as 300 mm of DOT -C2 reflective tape. I enclose a copy of the recent final rule which extended these requirements to truck tractors, and have circled language on p. 41357 which mentions this point.

I hope that this is responsive to your request. If you have any further questions, you may call Taylor Vinson at 202-366-5263.

Sincerely,

John Womack

Ms. Jo. Campfield
Vice President
Ultra Bond Licensing Corporation
2458 I-70 Business Loop, Ste. B-1
Grand Junction, CO 81501

Dear Ms. Campfield:

This responds to your request for an interpretation of this agency's laws that apply to your new product, EDGEGUARD, a clear material that is placed on the outer three inches or less of a windshield perimeter to prevent cracks. I apologize for the delay in responding.

As you are aware from past correspondence, the National Highway Traffic Safety Administration (NHTSA) has the authority to regulate the manufacture of new motor vehicles and motor vehicle equipment. NHTSA has promulgated Federal Motor Vehicle Safety Standard (FMVSS) No. 205, Glazing Materials, which specifies performance and location requirements for motor vehicle glazing. For windshields, Standard No. 205 specifies minimum levels of light transmittance (70 percent) and light stability; resistance to abrasion, delamination (humidity and boil tests), impact and penetration; and maximum levels of optical deviation and distortion. The various tests and criteria are contained in ANSI/SAE Z26.1, which is incorporated by reference in Standard No. 205.

NHTSA has stated in past interpretation letters that films such as the type your letter describes are not glazing materials themselves, and would not have to meet Standard No. 205. However, depending on who installs the glazing, installation of such films on new motor vehicles may be prohibited if, after installation, the vehicle glazing no longer meets the requirements of Standard No. 205, such as those for light transmittance, abrasion resistance and optical distortion.

A vehicle manufacturer or dealer placing your film on glazing in a new vehicle prior to sale of the vehicle must certify that the glazing continues to meet Standard No. 205. 49 U.S.C. Section 30112(a) prohibits any person from manufacturing for sale, offering for sale or selling any motor vehicle or equipment that fails to comply with applicable safety standards, including Standard No. 205. After the vehicle has been sold to the first purchaser, the owner may modify the vehicle as he or she pleases, subject to State requirements. Under Federal law, the owner could install your product on the vehicle whether or not such installation adversely affects the light transmittance and other properties of the vehicle's glazing. However, we urge consumers not to degrade the safety of their vehicles.

49 U.S.C. Section 30122(b) provides that a manufacturer, distributor, dealer or motor vehicle repair business "may not knowingly make inoperative" any device or element of design installed on or in a motor vehicle in compliance with an applicable motor vehicle safety standard. "Make inoperative" means to remove, disconnect or degrade the performance of a system or element of design installed pursuant to the FMVSSs. Thus, none of these persons may knowingly install your film on a vehicle for its owner if the installation would make inoperative the light transmittance or abrasion resistance of the vehicle glazing. Violations of this section may result in Federal civil penalties of up to $1,100 for each violation.

Because State law may affect the installation of your product on owners' vehicles, you should check the law in the States where you believe your product may be sold or installed for any applicable requirements.

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

TITLE: FMVSS INTERPRETATION

TEXT: This is in reply to your letter of November 23, 1982, to Mr. Elliott of this agency asking whether you may distinguish between U.S. and Japanese-manufactured lighting equipment subject to Federal Standard No. 108 by marking the lenses "U.S.A. DOT" and "JAPAN DOT", rspectively.

As you know, the National Highway Traffic Safety Administration has not adopted the SAE standard on equipment marking, J759c. This means that the only marking subject to Standard No. 108 is that which certifies compliance to all applicable Federal motor vehicle safety standards, the DOT symbol. We believe that the intended proximity of the words "Japan DOT" in your Japanese-manufactured equipment might create the impression that Stanley was certifying compliance to the requirements of the Japanese Ministry of Transport, rather than to those of the U.S. Department of Transportation. Therefore, we suggest that you place the word "Japan" at the end of the line rather than adjacent to the "DOT" symbol.

SINCERELY,

Dear Mr. Elliott,

We, Stanley Electric Co., Ltd. corporated in Japan (hereafter reffered to as STANLEY-JPN) have estblished Stanley Electric U.S. Co., Inc. corporated in London, Ohio (hereafter reffered to as STANLEY-US) with 100 % investments, and we are in process of preparing to start producing, beginning with the lighting equipments for 1984 model vehicles.

In the work we are proceeding, we are faced with a problem, the first case for us, which relates to the identification marking to be indicated on the lighting devices. So, we would like to ask you whether or not our view is right.

Honda Motor Co., LTD. (Japan) will manufacture the same type of vehicles both in Japan and in U.S.A (HONDA OF AMERICA). Therefore, their lighting devices of the same design will be manufactured by STANLEY-JPN and by STANLEY-US, and supplied to the Honda plant in each area.

Because these lighting devices are of the same design (STANLEY-JPN keeps the original drawings. And only STANLEY-JPN takes proceedings for their modifications.), we intend to indicate the same indentification making to the products made in Japan and made in U. S. A. However, in order to make a country of origin clear, it is our intention to add the marking "JAPAN" or U.S.A." to the identification marking, though it is not explained in Lighting Identification Code-SAE J759c.

The following is an example:

For products made in Japan : "STANLEY 043-6371 SAE AIST 80 JAPAN DOT"

For products made in U.S.A.: "STANLEY 043-6371 SAE AIST 80 U.S.A. DOT"

Please let us know whether or not the above view has no problem.

Mr. Bruce Henderson Automobile Importers of America, Inc. 1735 Jefferson Davis Highway, Suite 1002 Arlington, Virginia 1002 Dear Mr. Henderson:

This is in reply to your letter to Mr. Vinson of this office, in which you asked for an interpretation of Motor Vehicle Safety Standard No. 108. Specifically, you would like to know whether a supplementary turn signal unit may be added to each front fender near the wheel well of a vehicle already equipped with a turn signal system meeting Standard No. 108. You also asked whether there were any restrictions on the mounting height of such a lamp.

Standard No. 108 allows lighting equipment additional to that required by the standard provided that it does not impair the effectiveness of the lighting equipment that the standard requires (paragraph S4.1.3). The supplementary turn signal unit that you describe would appear to enhance the effectiveness of the required turn signals rather than detract from them. There is no requirement that equipment, added at the option of the manufacturer, meet the specific requirements of the standard applicable to identical or similar items of equipment; i.e., the supplementary unit is not legally required to have the same flash rate as the primary turn signals, nor is it subject to the same mounting height restrictions. Obviously, if these specifications are met, supplementary equipment is less likely to impair the effectiveness of the required equipment within the meaning of S4.1.3.

As you are no doubt aware, some manufacturers are wiring their front side marker lamps to flash with the turn signals. This type of supplementary system is acceptable to us.

I hope that this answers your questions.

Dear Mr. Vincent:

We would like to request all interpretation of the application of Federal Motor Vehicle Safety Standards (in particular, FMVSS 108) in the following case:

A passenger car complies fully with the requirements for turn signals in FMVSS 108. Is it permissable to add a "turn signal repeater lamp" to each front fender near the wheel well? This repeater lamp would indicate to a vehicle in an adjacent lane an intention to change lanes. The vehicle would continue to to meet requirements in FMVSS 108 for rate of flash, bulb burnout indications, etc.

If the use of such turn signal repeaters in addition to the "four-corner" signal lamps is permissible, is there any restriction on the mounting height - maximum or minimum?

Thank you for your attention and assistance in this matter.

Mr. T. Chikada Manager, Automotive Lighting Engineering Control Dept. Stanley Electric Co., Ltd. 2-9-13, Nakemeguro, Meguro-ku Tokyo 153, Japan

Dear Mr. Chikada:

This is in reply to your letter of March 13, 1987, with respect to the mounting height of driving lamps and front fog lamps. Noting that these lamps are not equipment required by Federal Motor Vehicle Safety Standard No. 108, you have asked whether they need to be mounted within the range of height which the standard prescribes for headlamps, or may they be mounted, for example, at a height lower than 22 inches such as in the front bumper.

Any lamp that is not required by Standard No. 108 may be added to a motor vehicle and located wherever it appears suitable, provided that the lamp at its location does not impair the effectiveness of lighting equipment required by the standard. Headlamps , parking lamps, and turn signal lamps are the lighting equipment required by Standard No. 108 on the front of a passenger car, and any other four-wheeled vehicle of less than 80 inches overall width. Although Standard No. 108 imposes a minimum mounting height of 22 inches on headlamps, it allows parking lamps and turn signal lamps to be mounted as low as 15 inches above the road surface, which means that they could be mounted in the front bumper, or otherwise close to the mounting location of fog lamps and driving lamps. Therefore, compliance with paragraph S4.1.3 of Standard No. 108 would require a manufacturer of a vehicle equipped with fog and driving lamps to ensure that they do not impair the effectiveness of the headlamps, turn signal lamps, and parking lamps.

Because fog lamps and driving lamps are not covered by Standard No. 108, the individual States may have their own restrictions on the mounting height of these lamps. We regret that we are unable to advise you on these laws. However, the American Associat ion of Motor Vehicle Administrator (AAMVA), 1201 Connecticut Ave., N.W., Washington, D.C., may be able to advise you.

Dear Ms. Jones,

Re : Mounting height of auxiliary driving lamps and front fog lamps

We have a question on mounting height of driving lamps and front fog lamps.

Do they need to be mounted within the range of height which is required for headlamps in FMVSS No. 108?

Although they help the function of headlamps, they are not required lighting equipments in FMVSS No. 108.

So we understand that they can be mounted in the lower position than 22 inches, the lower required height of headlamps; for example, into the front bumper, the height of which is less than 22 inches.

We would like to have your confirmation on this matter. We are looking forward to your reply.

ATTACHMT: LETTER DATED 04/20/88 TO ERIKA Z. JONES FROM GEORGE ZIOLO RE HEADLAMP COMBINATIONS-REQUEST FOR CLARIFICATION, FMVSS 108; OCC - 1932;

TEXT: Dear Mr. Ziolo:

This is in reply to your letter of April 20, 1988, asking about the acceptability under Safety Standard No. 108 of modifying imported vehicles so that they are equipped with two Type 2D1 and two Type 1C1 headlamps. You have been informed by the agency's Office of Vehicle Safety Compliance that this is impermissible "because they are 'nonconforming' 'headlight systems'." You disagree because you believe that the minimum requirements of the Standard are satisfied by the Type 2D1 lamps, and that "S4.4 app ears to permit such a combination."

Paragraph S4.4 is not applicable to the situation you present as it refers to combinations of lamps serving different functions; in your discussion, the lamps serve the identical function of headlighting. Given the fact that the Type 2D1 sealed beam 7" diameter headlamps fulfill the headlighting requirements of the Standard, your question must be viewed as whether a supplement to the headlighting system is permissible under Standard No. 108.

Paragraph S4.1.3 of Standard No. 108 permits the addition of nonrequired lighting equipment provided it does not impair the effectiveness of the equipment that the standard requires. The two Type 1C1 5 3/4" diameter sealed beam lamps in a four lamp head lighting system form the major portion of an upper beam headlighting system. The two Type 2D1 lamps in a two lamp headlighting system form the whole of an upper beam headlighting system. Thus, a vehicle furnished with the systems you posit would be equ ipped with more than one upper beam headlighting system. The Type 2D1 system must be designed to conform to the photometric requirements of SAE Standard J579c DEC79 "Sealed Beam Headlamp Units for Motor Vehicles." The SAE Standard establishes at two tes t points, H-V and 4 D-V, maximum allowable candela of 75,000 and 5,000 respectively for each Type 2D1 headlamp. This means that the maximum allowable candela for headlighting systems at these test points is 150,000 and 10,000 candela. The Type 1C1 head lamps will also be designed to conform to SAE J579c. Corresponding maxima at test points H-V and 4 D-V for Type 1C1 systems are 60,000 and 5,000. Thus, a vehicle equipped

with the lamps you have described could emit a total of 270,000 candela at test point H-V (when only 150,000 is permitted), and 20,000 at 4D-V (when only 10,000 is allowable).

Agency research has shown that candela readings in excess of 150,000 greatly increase the potential for glare with little increase in seeing ability. This glare would be visible both to the driver of an oncoming car, and the driver of the modified vehic le itself through creation of a "veiling" glare. The addition of the Type 1C1 headlamps would therefore impair the effectiveness of the Type 2D1 headlighting system, and is forbidden by S4.1.3.

We appreciate your interest in safety.

ATTACHMT: Attached to report entitled NHTSA Office of Vehicle Safety Compliance Reports Accepted During September 90 for Test Program 90

TEXT:

We have received the (unsigned) petition of SportsCar America, Inc., for a temporary exemption from Motor Vehicle Safety Standard No. 208, on grounds of substantial economic hardship, and are returning all copies to you for the reasons stated below.

SportsCar America wishes to undertake the importation and sale of passenger cars produced in Brazil. Pursuant to an "Exclusive Distribution Agreement" ("the Agreement") with Alfa Metais Veiculos Ltda. of Brazil, which you enclosed, it has imported a pro totype vehicle for study, with reference to its status of conformance with the U.S. vehicle safety and emission standards.

The proper petitioner for this exemption is Alfa Metais Veiculos Ltda., identified in the Agreement that you attached as the "Manufacturer." Under Section 1 of the Agreement, SportsCar America is to return the prototype to the Manufacturer with "those mo difications necessary in order to meet the emission and safety standards necessary for the importation" of the cars, and the Manufacturer will then use it as a model for the production of vehicles for sale in the United States. Under 49 CPR Part 567, th e Manufacturer must also attach its certification of compliance to the completed vehicle before its shipment to the United States. Part 555 restricts petitions for temporary exemptions to Manufacturers of motor vehicles.

Although you identify SportsCar America as the "distribution agent", we have no record that the Manufacturer has filed the designation of agent pursuant to 49 CPR 551.45 that is required of Manufacturers offering their products for importation and sale i n the United States. Presumably Alfa Metais would wish to appoint SportsCar America as its agent. Once it has done so, SportsCar America may submit the petition on behalf of the Manufacturer. The production and financial data (in dollars, please) must be those of the Manufacturer. However, we regard as relevant to conformance arguments the efforts that SportsCar America intends to make during the time a possible exemption is in effect, as outlined in your petition.

Noting your requests for confidential treatment of information, we are returning all copies of your petition, with our comments. Generally, the agency does not like to accord confidential treatment to all financial data submitted. At a minimum, it woul d like to include in its notice asking comments from the public a dollar amount of the cumulative net profit or loss experienced by the Manufacturer in the three years preceding the filing of the petition. Similarly, it would like to publish a dollar fi gure in discussing the effects of a denial of the petition on

the petitioner. The purpose of this is our policy that if the public is to make an informed comment on the issue of whether compliance would cause a Manufacturer substantial economic hardship, the public should have access to much the same data as is av ailable to the agency in its determination.

If you would like clarification of any of these matters, Taylor Vinson of this Office (202-366-5263) will be happy to provide them.

ATTACHMT: ATTACHED TO LETTER DATED 08/24/89 EST; FROM JEFFREY R. MILLER -- NHTSA TO MICHAEL E. KASINER -- NATIONAL TRUCK EQUIPMENT ASSOCIATION; REDBOOK A34, STANDARD 204; LETTER DATED 08/01/89 FROM MICHAEL E. KASTNER -- NATIONAL TRUCK EQUIPMENT ASSOCIATI ON; TO SAMUEL K. SKINNER -- DOT, OCC 3809; LETTER DATED 08/26/87 FROM ERIKA Z. JONES -- NHTSA TO TAK FUJITANI

TEXT: Dear Mr. Chairman:

Thank you for your letter, co-signed by other members of the Senate Commerce Committee, concerning the issuance of certain safety standards for light trucks and vans ("LTV's"), including sport utility vehicles. I share your interest in ensuring that occ upants of these vehicles are well protected. As I stated in my confirmation hearing, I place a high priority on the safety of all our transportation systems including motor vehicles used for personal travel. I wish to assure you that the Department is moving expeditiously to improve vehicle safety, including rulemaking for additional LTV safety standards.

The Department has carefully reviewed those passenger-car safety standards which do not currently apply to LTV's, as evidenced by our reports to Congress in May 1987 and April 1988. As noted in those reports, we are committed to prompt rulemaking action s and decisions. Specifically, the Department's National Highway Traffic Safety Administration (NHTSA) has already issued Notices of Proposed Rulemaking (NPRM) to require both head restraints and rear-seat lap/should belts in LTV's, and an Advance Notice of Proposed Rulemaking to require side-impact protection in LTV's. In addition, NHTSA is currently preparing an NPRM to establish a minimum roof-crush resisance standard for LTV's.

In each of these four areas -- head restraints, side-impact protection, roof-crush resistance, and rear-seat lap/shoulder belts -- I expect to begin discussions within the Administration during the next 90 days on our recommendations for the next rulemak ing actions to be taken. These discussions will also address an NPRM to require automatic occupant protection for LTV's. I will advise you of the conclusion of these discussions.

NHTSA is also analyzing the research on how to enhance brake light performance on these vehicles, and expects to make a decision on requiring additional stop lamps by the end of the summer. Lastly, NHTSA has already granted a petition for rulemaking to d evelop a rollover protection standard and has a comprehensive data collection and research program under way to provide the basis for an effective regulation. Most of that research should be completed by year's end, and I assure you that we will not tol erate delays in the research schedule.

We note that the Department has initiated these and other vehicle safety rulemaking proceedings under the National Traffic and Motor Vehicle Safety Act, which provides a solid, effective, legal framework for these activities. Therefore, we do not believe that specific legislative mandates and timetables for LTV rulemaking projects are necessary or appropriate.

In closing, I appreciate your concern for improving the safety of vehicles and highway travel. Please be assured that this Department will continue to take whatever actions are needed to assure further progress in highway safety.

Sincerely,
