Dear Mr. Beyer:

This responds to your FAX of September 22, 1992, to Taylor Vinson of this Office with reference to your request to become a Registered Importer ("RI"). We interpret your letter as seeking an opinion on your eligibility to submit an application to become an RI under 49 CFR 592.

Because of your representation of RIs, you are familiar with the record keeping mechanisms and other regulatory requirements of this agency. Your intent is to perform modifications on those Canadian vehicles which require only minor modifications, and you have a 3-car garage, tools including pneumatics, and storage space. You would have in your employ several people qualified to perform the modifications required. You are aware that, in promulgating Part 592, NHTSA specificaly rejected a proposal to allow RIs to designate agents to perform conformance work, thus you would not accept vehicles requiring major modifications, but would refer those to the other RIs.

Section 592.5 sets forth the requirements for registration as an RI. According to paragraph 592.5(a), "any person" may file an application. An application must contain the information specified by the subparagraphs of paragraph (a). We note no restrictions upon who is eligible to apply for RI status. We therefore see no legal impediment to your submitting an application under section 592.5.

The Office of Vehicle Safety Compliance (OVSC) has the authority to grant or deny applications for RI status. Your application must, therefore, contain arguments sufficient to convince OVSC of your ability to perform the limited modifications that you contemplate. We advise you, therefore, to set out with specificity in your application the Federal motor vehicle safety standards for which you have the capability to conform vehicles, and the standards for which you have not. We would like to make clear that, in the event a vehicle requires major modifications, our regulations would not allow you to bring the vehicle into partial conformance before transfering the vehicle to another RI for to complete the conformance process. An RI must certify the conformance work to NHTSA, and paragraph 592.6(e) requires the RI's certification to state that "it is the person legally responsible for bringing the vehicle into conformity." We interpret that as meaning that the certifier itself performed all the conformance work and did not resort to an agent.

Sincerely,

Paul Jackson Rice Chief Counsel

Evansville, IN 47711

Dear Mr. Thurman:

This responds to your letter of October 1, 1992 requesting information on whether certain modifications can be made to a van to make room for a wheelchair to enter the vehicle. You explained that you currently own a 1983 Ford van with a lift. The passenger seats behind the front seats were moved back in your 1983 van to make room for the wheelchair lift. You are currently trying to purchase a new Ford van with the same modifications but have been told that federal law no longer permits moving seats or safety belts. As explained below, there is no federal requirement that expressly prohibits moving seats or safety belts, provided that the relocated seats and belts continue to comply with the applicable safety standards.

Section 103 of the National Traffic and Motor Vehicle Safety Act (the Safety Act; 15 U.S.C. 1392) authorizes NHTSA to issue Federal Motor Vehicle Safety Standards for new motor vehicles and new items of motor vehicle equipment. Manufacturers are required to certify that their products meet all applicable safety standards. Thus, if a vehicle were originally manufactured in the manner you have described, the manufacturer would be required to certify that the vehicle complies with all applicable safety standards. If some party were to modify a vehicle along the lines described in your letter before the vehicle's first sale to a consumer like yourself, that party would be required to leave the original manufacturer's certification in place and add its own certification that the vehicle as altered continues to comply with all applicable safety standards.

Moving the rear seats and the seat belts for those seats could affect compliance with four safety standards: Standard No. 207, Seating Systems, Standard No. 208, Occupant Crash Protection, Standard No. 209, Seat Belt Assemblies, and Standard No. 210, Seat Belt Assembly Anchorages. Standard No. 207 establishes strength and other performance requirements for vehicle seats. Standard No. 208 sets forth requirements for occupant protection at the various seating positions in vehicles. Based upon the information in your letter, it appears that the vehicle you wish to have modified would be classified as a multipurpose passenger vehicle (MPV) for purposes of NHTSA's regulations. Standard No. 208 requires an MPV to have a lap/shoulder belt at every rear outboard seating position, and either a lap belt or a lap/shoulder belt at every other rear seating position. Standard No. 209 sets forth strength, elongation, webbing width, durability, and other requirements for seat belt assemblies. Standard No. 210 establishes strength and location requirements for seat belt anchorages.

Any manufacturer, distributor, dealer, or repair business that modifies a van for you along the lines described in your letter after you have purchased the van would be subject to the requirement of the Safety Act (at 15 U.S.C. 1397(a)(2)(A)) that:

No manufacturer, distributor, dealer, or motor vehicle repair business shall knowingly render inoperative, in whole or in part, any device or element of design installed on or in a motor vehicle . . . in compliance with an applicable Federal motor vehicle safety standard.

Since the rear seats and their safety belts are devices or elements of design installed in the van in compliance with applicable safety standards, this section prohibits any of the named commercial entities from making any modification or repair to the rear seats and/or their accompanying safety belts if such modification or repair would cause the vehicle no longer to comply with an applicable safety standard.

As you can see, there is nothing in Federal law that prohibits persons from moving rear seats and their accompanying safety belts. Instead, Federal law requires that modifications to a van that include moving the rear seats and the safety belts be done in such a way that the repositioned seats and safety belts continue to provide the safety protection mandated by the safety standards.

I hope you find this information helpful. If you have any other questions or need some additional information on this matter, please contact Mary Versailles of my staff at this address or by phone at (202) 366-2992.

Sincerely,

Paul Jackson Rice Chief Counsel ref:207#208#209#210 NCC-20:MVersailles:amb:62992:10/22/92 U:\NCC20\INTERP\208\7822.MLV cc: NCC-01 Subj/Chron, NCC-20 MV, NRM-01, NEF-01 Interps: 207, 208, 209, 210, Redbook (8)

Michael J. Vacanti
7533 W. 112th Street
Bloomington, MN 55438

Dear Mr. Vacanti:

This responds to your letter seeking information on how the laws and regulations administered by this agency would apply to a device you have designed. According to your letter, this device is an aftermarket accessory. The accessory is a polyurethane device that latches onto the lap/shoulder belt and changes the angle at which the shoulder belt crosses a child's torso. The device is intended to improve shoulder belt fit for children that have outgrown child safety seats. I am pleased to have this chance to explain our laws and regulations to you.

The National Traffic and Motor Vehicle Safety Act (15 U.S.C. 1381 et seq.; the Safety Act) authorizes this agency to issue motor vehicle safety standards for new motor vehicles and new items of motor vehicle equipment. We have exercised this authority to establish Standard No. 208, Occupant Crash Protection (49 CFR 571.208). This standard requires new motor vehicles to be equipped with safety belts and requires that those belts meet specified fit and comfort requirements, as set forth in S7 of the standard. However, Standard No. 208 does not apply to aftermarket items that seek to alter belt fit and/or comfort. Hence, you are not required to certify that this device complies with Standard No. 208 before offering the device for sale.

In addition, you are not required to get some sort of "approval" from this agency before offering this device for sale. NHTSA has no authority to "approve" motor vehicles or motor vehicle equipment, nor do we endorse any commercial products. Instead, the Safety Act establishes a "self- certification" process under which each manufacturer is responsible for certifying that its products meet all applicable safety standards. As stated above, this device is not subject to any safety standard, so you do not have to make any certification.

Although none of our safety standards directly apply to this device, there are several provisions in the Safety Act that are relevant. Manufacturers of motor vehicle equipment such as your belt positioning device are subject to the requirements in sections 151-159 of the Safety Act (15 U.S.C. 1411-1419) concerning the recall and remedy of products with defects related to motor vehicle safety.

In addition, use of your product could be affected by section 108(a)(2)(A) of the Safety Act (15 U.S.C. 1397(a)(2)(A)). That section prohibits manufacturer, distributors, dealers, and repair shops from knowingly "rendering inoperative," in whole or in part, any device or element of design installed on or in a vehicle in compliance with an applicable safety standard. There are two elements of design in a vehicle that might be "rendered inoperative" by the use of your belt positioning device. One is the occupant protection afforded by belts that meet the specified fit and comfort requirements. The other element of design that could be rendered inoperative by the use of your belt positioning device is the burn resistance required by Standard No. 302, Flammability of Interior Materials (49 CFR 571.302). The materials used in the interior of vehicles, including the seat belts, seat backs and cushions, trim panels, and headliner must comply with the burn resistance requirements of Standard No. 302 to reduce deaths and injuries in the event of a fire in the vehicle's interior. If your belt positioning device renders inoperative the belt fit and comfort requirements specified in Standard No. 208 or does not comply with burn resistance requirements, it could not be installed in a vehicle by any manufacturer, distributor, dealer, or repair shop.

I have enclosed a general information sheet for new manufacturers that gives a thumbnail sketch of NHTSA's regulations and provides information on how to obtain copies of those regulations.

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

Sincerely,

Paul Jackson Rice Chief Counsel

President
S.C.C. CARAT Inc.
109 Maple Avenue
Huntsville, AL 35801

Dear Mr. Scheys:

This responds to your letter of October 2, 1992, asking for an explanation of how this agency's regulations would affect two types of vehicle conversions your company plans to undertake.

In the first situation, a customer in California wishes to send two "U.S. spec" cars that he presently owns to Europe for a 39-inch stretch conversion. In the second situation, the customer would take delivery of a "U.S. spec car" in Europe, use it for tourist purposes, and leave it at your factory for conversion, and subsequent shipment to the United States. You also ask for "advice for the case where we have to convert a car into an armoured car." I am pleased to have this opportunity to explain our laws and regulations for you.

The National Traffic and Motor Vehicle Safety Act (the Safety Act) provides generally that no person shall manufacture, sell, or import into the United States any motor vehicle unless that vehicle is in conformity with all applicable U.S. motor vehicle safety standards and is covered by a manufacturer's certification to that effect. The certification requirements are set forth in 49 Code of Federal Regulations, Part 567. The certification requirements apply to persons and entities that perform some manufacturing or conversion activities to a vehicle before that vehicle's first sale for purposes other than resale. This means that the original manufacturer of a vehicle (Mercedes-Benz, for instance) must certify that each of its completed vehicles conforms to all applicable U.S. safety standard and permanently affix a label with that statement on each such vehicle. For the purposes of this letter, I am assuming that the cars you call "U.S. spec" cars are cars to which the original manufacturer has affixed its certification label.

If any party performs conversion operations on a certified vehicle before the initial purchase of the vehicle, the party would be an "alterer" and required to affix its own label identifying itself and certifying that the converted vehicle continues to conform to all applicable Federal motor vehicle safety standards. See 49 CFR 567.7. However, in the situations posited in your letter, the conversions to be performed in Europe by your company would be performed on vehicles after the first purchase of the vehicle for purposes other than resale. This agency does not require any certification to be made or certification label to be affixed by entities that perform conversions on vehicles after the first purchase of those vehicles. Thus, your company need not make its own certification nor affix its own label. Instead, your company must leave in place the original manufacturer's certification label.

The only provision in U.S. law that applies to conversion operations performed on vehicles after the first purchase in good faith for purposes other than resale is set forth in Title 15, United States Code, section 1397(b)(2). That section of the law forbids any "manufacturer, distributor, dealer, or motor vehicle repair business" from "knowingly rendering inoperative in whole or in part any device or element of design installed in accordance with a Federal motor vehicle safety standard." This means that your company must ensure that your conversion operations do not cause the converted vehicle to no longer comply with the U.S. motor vehicle safety standards. Pursuant to this responsibility, the agency would, for example, expect that, if the vehicle's weight ratings and tire inflation pressures shown on its original certification labels were no longer valid after conversion, a converter would install new labels showing the correct weight ratings and tire inflation pressures.

Assuming your company leaves the original manufacturer's certification label in place on the converted vehicles, the owner of the vehicles should not encounter any difficulties when the converted vehicles are imported into the United States. The importer would simply file a declaration stating that the vehicle conforms to the applicable safety standards and bears an original manufacturer's certification label to that effect, pursuant to 49 CFR 591.5(b).

For your information, I have enclosed a copy of an information sheet for new manufacturers that briefly explains our regulations and tells how to obtain copies of those regulations. I hope this information is helpful.

Sincerely,

Paul Jackson Rice Chief Counsel

Robert R. McAusland, P.E.
1311 N. 35th St.
Seattle, WA 98103

Dear Mr. McAusland:

This responds to your letter asking whether your design of an infant seat would comply with S5.2.4 of Federal Motor Vehicle Safety Standard No. 213, Child Restraint Systems. You state that your infant seat would have a frame made from 1/4 inch thick polyethylene sheet, and that all the edges of the frame are rounded to a radius of 1/8 inch. As discussed below, the design would not comply if the edges of the seat frame are contactable by the infant dummy's head or torso during the standard's dynamic test.

Some background information on Federal motor vehicle safety laws and regulations may be helpful. The National Traffic and Motor Vehicle Safety Act (15 U.S.C. 1381 et seq., Safety Act) authorizes this agency to issue safety standards applicable to new motor vehicles and items of motor vehicle equipment. NHTSA, however, does not approve motor vehicles or motor vehicle equipment, nor do we endorse any commercial products. Instead, the Safety Act establishes a "self- certification" process under which each manufacturer is responsible for certifying that its products meet all applicable safety standards. The following represents our opinion based on the facts set forth in your letter.

Standard No. 213 specifies requirements for child restraint systems used in motor vehicles and aircraft, to reduce the number of children killed or injured in motor vehicle crashes and in aircraft. S5.2.4, "Protrusion limitation," of Standard No. 213 states:

Any portion of a rigid structural component within or underlying a contactable surface, or any portion of a child restraint system surface that is subject to the requirements of S5.2.3 [the head impact protection requirements for infant seats], shall, with any padding or other flexible overlay material removed, have a height above any immediately adjacent restraint system surface of not more than 3/8 inch and no exposed edge with a radius of less than 1/4 inch. (Emphasis added.)

The term "contactable surface" is defined in S4 of the standard as "any child restraint system surface (other than that of a belt, belt buckle, or belt adjustment hardware) that may contact any part of the head or torso of the appropriate test dummy, specified in S7, when a child restraint system is tested in accordance with S6.1."

Under S5.2.4, any edges of a rigid structural component within or underlying a surface that can be contacted by the head or torso of the appropriate test dummy during Standard No. 213's dynamic test must have a radius of at least 1/4 inch. Since the frame edges of your infant seat have a radius of only 1/8 inch, the seat would not comply with S5.2.4 if the surfaces overlying those edges can be contacted by the infant dummy during the dynamic test.

You ask whether, since side loading is not specified in Standard No. 213, can you conclude that there is no way that the child's head or torso could contact the sides of the frame, i.e., that the surfaces overlying those edges cannot be contacted by the infant dummy during the dynamic test. We assume that you believe the infant's head and torso are unlikely to contact the frame's edges in the 213 dynamic test since, due to the forward motion of the test, the dummy's components are likely to move forward and rearward, rather than laterally.

I note that, for purposes of compliance testing, NHTSA would determine whether the surfaces are contactable surfaces for the purposes of S5.2.4 by observing a dynamic test, conducted according to the procedures in Standard No. 213. With respect to the issue of what information or analysis would be sufficient, for purposes of certification, for you to conclude that the surfaces overlying those edges cannot be contacted by the infant dummy during the dynamic test, manufacturers must have some basis for their certification that a product complies with all applicable safety standards. However, this does not necessarily mean that a manufacturer must conduct the specific tests set forth in an applicable standard. Certifications may be based on, among other things, engineering analyses, actual testing, and computer simulations.

You should be aware, however, that the direction of dummy movement during the Standard No. 213 dynamic test depends on many variables other than the direction of the test, such as the performance of the restraint's belt system. For example, in the event a child seat's upper torso restraint slipped off the dummy's shoulder in the dynamic test, the dummy could move laterally and strike the sides of the restraint system. You should consider all of the variables that could affect the dummy's performance when determining whether frame contact can occur.

I also note that manufacturers of motor vehicles and motor vehicle equipment are subject to the defect provisions of the National Traffic and Motor Vehicle Safety Act. Infant restraints are involved in real-world crashes other than the frontal impacts simulated in Standard No. 213. If data indicated that a child seat exposed occupants to an unreasonable risk of injury, such as sharp edges resulting in injuries in a side crash, the agency might conduct a defect investigation which could lead to a safety recall.

Enclosed is an information sheet which provides additional information for new manufacturers of motor vehicles and motor vehicle equipment. If you have further questions, please call Ms. Deirdre Fujita of my staff at (202) 366- 2992.

Paul Jackson Rice Chief Counsel

P.O. Box 52025
Phoenix, AZ 85072-2025

Dear Mr. Gayer:

This responds to your letter asking whether certain trailers, manufactured in 1989, were required to comply with Federal Motor Vehicle Safety Standard No. 121, Air Brake Systems. (49 CFR 571.121). You explained that you disagree with statements by the trailers' manufacturer that "these trailers do not need to comply with `121,' because they are `Heavy Haul Trailers.'" You further stated that the trailers may not comply with certain provisions in Standard No. 121, including the reservoir requirements in S5.2.1.1 and S5.2.1.5.

I note that we previously responded to a similar letter from Salt River Project concerning certain trailers manufactured in 1987. Our letter (copy enclosed) was sent to Mr. Derral T. Crance on April 3, 1989. We explained that heavy hauler trailers are not excepted from Standard No. 121 unless they have a GVWR of more than 120,000 pounds. Since you indicated that the trailers of current concern have a GVWR of 68,000 pounds, they would not be excepted from the standard as heavy hauler trailers. Moreover, the trailers do not appear to come within any of the other exceptions to Standard No. 121.

Standard No. 121 does, however, include a number of special provisions for heavy hauler trailers, including exceptions from certain requirements. Of particular note, S5.6 sets forth a number of specific parking brake requirements but permits heavy hauler trailers to meet the requirements of either that section, or, at the option of the manufacturer, the requirements of 49 CFR 393.43. Part 393 requires commercial motor vehicles to be equipped with various types of equipment, including brakes. Specifically, section 393.43 addresses brake requirements in breakaway and emergency braking situations.

Heavy hauler trailers manufactured in 1989 were generally subject to sections S5.2.1.1 and S5.2.1.5 of Standard No. 121, the provisions about which you specifically asked. Under S5.2.1.1, a reservoir was required to be provided that is capable of releasing the vehicle's parking brakes at least once and that is unaffected by a loss of air pressure in the service brake system. Under S5.2.1.5, each service reservoir was required to be protected against loss of air pressure due to failure or leakage in the system between the service reservoir and its source of air pressure by check valves or equivalent devices.

Notwithstanding the general applicability of S5.2.1.1, certain heavy hauler trailers which complied with the requirements of 49 CFR 393.43 instead of the specific parking brake requirements set forth in S5.6 would not have had to comply with S5.2.1.1. This is so because the vehicle is not required to have parking brakes. However, a braking system is required which applies automatically and promptly upon breakaway from a towing vehicle. Such a vehicle would also be required to carry sufficient chocking blocks to prevent movement when parked, as required by 393.41.

Since your letter suggests that you purchased trailers that may not have complied with Standard No. 121, I have referred the matter to our Office of Vehicle Safety Compliance for appropriate action.

I hope this information is helpful. If you have any further questions about NHTSA's safety standards, please feel free to contact Marvin Shaw of my staff at this address or by telephone at (202) 366-2992.

Mr. T. Kouchi Director & General Manager Automotive Equipment Development & Administration Dept. Stanley Electric Co. Ltd. 2-9-13, Nakameguro-ku, Meguro-ku Tokyo 153, Japan

Dear Mr. Kouchi:

This responds to your letter of October 8, 1992, with respect to photometric test methods for a center high-mounted stop lamp using light emitting diodes (LEDs) as light sources.

Your letter presents certain procedures and asks for associated revisions in Federal Motor Vehicle Safety Standard No. 108. After review, we have come to the conclusion that your method of proposed testing is allowable under Standard No. 108, but more stringent than what the standard requires.

In the section of your letter called "BACKGROUND", you state that you usually follow the technical guidance of SAE J1889 as a standard practice for LED lighting devices. There is no requirement in Standard No. 108 or in any of the SAE standards incorporated by reference in Standard No. 108 that requires you to follow the test methodology of J1889. Thus, when you say that you "must always allow a margin of the same percentage when designing initial light output of the lamp, which necessitates increase in the number of LEDs used, lamp size, product cost, and, therefore, user's expense", you are placing a burden upon yourself that does exist under J1889, but one which is not necessary for designing for compliance with Standard No. 108.

You have proposed a solution for the problem you have created by following J1889, and you provide three specific reasons in support. The third reason is based upon your interpretation of SAE J575's warpage test, under which you test operating cycles of 5 minutes on and 5 minutes off. However, you reference a version of J575 which does not apply to center high-mounted stop lamps. Paragraph S6.1 of Standard No. 108 specifies that J575e, August 1970, applies to high-mounted stop lamps designed to conform to SAE Recommended Practice J186a. SAE J575, August 1970, simply specifies that the device is to be operated in the test in the same manner as it will be operated in service, far different than the cycle method you employ.

Thus, you have requested that we revise Standard No. 108 by adding a new provision that center high-mounted stop lamps shall be energized for a minimum of 5 minutes before measurement of photometric minima. We note that nothing prohibits you from testing in such a manner, but we believe that an amendment of this nature is not required because the present allowable method of testing does not call for it.

You have asked for our comments on four steps of photometric measurement, and our permission to follow them. There is no reason you may not follow them, if you wish, but they are unnecessary to design for compliance under Standard No. 108.

I hope that this is responsive to your questions.

Dear Ms. Stewart:

This responds to your letter of October 16, 1992, to this office regarding the installation of a "silent monitor" on school buses. You stated in your letter that you made a presentation to Mr. Maurice Hicks and Mr. Rich Van Iderstine of this agency at a meeting on October 2, 1992, and you asked how our standards apply to installation of this device on school buses.

You described the silent monitor as a six-inch cube of welded steel designed to house a video camera to monitor the interior of school buses. You explained that the device is installed in the interior access panel above the bus windshield facing the passenger compartment. The box protrudes into the interior of the bus by three to four inches. The front of the box, which swings open for installation of a video camera, contains a reflective solar glass window to prevent glare on the inside of the box.

By way of background information, NHTSA does not provide approvals of motor vehicles or motor vehicle equipment. Under the National Traffic and Motor Vehicle Safety Act (Safety Act), it is the responsibility of the manufacturer to ensure that its motor vehicles or equipment comply with applicable Federal safety standards. The following represents our opinion based on the facts provided in your letter.

NHTSA does not have any safety standards specifically covering silent monitors. However, it is possible that the installation of a silent monitor could affect the compliance of a vehicle with some safety standards.

All new motor vehicles manufactured for sale in the United States must be certified by their manufacturers as complying with the applicable Federal motor vehicle safety standards. If your silent monitor is installed in a new school bus prior to its first sale to a customer, the person making the installation would be considered a vehicle alterer. Under our certification regulation (49 CFR Part 567), a vehicle alterer must certify that the vehicle as altered continues to comply with all applicable Federal motor vehicle safety standards.

Manufacturers, distributors, dealers, or motor vehicle repair businesses modifying a used vehicle are prohibited by Section 108(a)(2)(A) of the Safety Act from knowingly rendering inoperative any safety device or element of design installed on or in a motor vehicle or item of motor vehicle equipment in compliance with an applicable Federal motor vehicle safety standard. Thus, if your silent monitor is installed in a used school bus, any businesses, including your own, making such installations cannot render inoperative the vehicle's compliance with any of our standards.

We also note that manufacturers of motor vehicle equipment have responsibilities under the Safety Act regarding safety defects. Under Sections 151, et seq., of the Safety Act, such manufacturers must notify purchasers about safety- related defects and remedy the product free of charge.

In order to determine how installation of your silent monitors could affect the compliance of school buses with applicable Federal safety standards, you should carefully review each standard, including but not limited to those addressing school bus body joint strength, crash protection, and windshield intrusion. In that regard, I am enclosing for your information a fact sheet entitled Information for New Manufacturers of Motor Vehicles and Motor Vehicle Equipment, and a booklet entitled Federal Motor Vehicle Safety Standards and Regulations.

As indicated above, you stated that your silent monitor would be installed in the interior access panel above the bus windshield facing the passenger compartment. Given the added weight that would be on the panel, we suggest that you carefully evaluate whether additional securement of the panel is needed to ensure that the panel and silent monitor do not come loose during a crash. We also note that the silent monitor appears to have sharp edges. You may wish to consider adding padding to prevent injury to an occupant who comes in contact with the monitor.

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

Post Office Box 35833
Tucson, AZ 85740-5833

Dear Mr. Motzkin:

This responds to your letter of October 14, 1992 regarding Federal requirements pertaining to brake specifications. In particular you asked whether there are any regulations requiring automotive brake drums and rotors not to be milled beyond manufacturer specifications, and whether manufacturers are required to stamp their specifications on brake drums and rotors. I am pleased to have this opportunity to explain our law and regulations for you.

The National Traffic and Motor Vehicle Safety Act of 1966 (Safety Act) authorizes the National Highway Traffic Safety Administration (NHTSA) to issue Federal motor vehicle safety standards for new motor vehicles and new motor vehicle equipment. All motor vehicles and items of motor vehicle equipment manufactured or imported for sale in the United States must comply with all applicable safety standards. This agency does not provide approvals of motor vehicles or motor vehicle equipment. Under the Safety Act, the manufacturer is responsible for certifying that its motor vehicles or equipment meet applicable standards.

NHTSA has issued a number of safety standards which specify performance requirements for new motor vehicle brake systems and certain new brake equipment. The standards do not require manufacturers to stamp specifications on drums or rotors, although it is common practice for manufacturers to do so.

The Federal motor vehicle safety standards do not apply to a motor vehicle after its first sale to a consumer. However, manufacturers, distributors, dealers, or motor vehicle repair businesses modifying a used vehicle are prohibited by section 108(a)(2)(A) of the Safety Act from knowingly rendering inoperative any safety device or element of design installed on or in a motor vehicle or item of motor vehicle equipment in compliance with a safety standard. The milling or turning of brake drums and rotors is typically performed during the course of repairing a used vehicle with worn brakes. We do not believe that the "render inoperative" provision would ordinarily be relevant to such a situation.

The states may regulate the repair of motor vehicles. We suggest you investigate the laws of Arizona to see whether they affect your situation.

I hope this information is been helpful. If you have any further questions about NHTSA's safety standards, please feel free to contact David Elias of my staff at this address or by telephone at (202) 366-2992.

Dear Mr. Nielsen:

This responds to your letter of October 21, 1992, to Walter B. McCormick, Jr. (the General Counsel of this Department). You have written for "further explanation of S5.3.1.1.1 in FMVSS 108."

You have heard that there is an additional interpretation with respect to the location of clearance lamps on boat trailers whose overall width is 80 inches or more, which would allow mounting of these lamps in accordance with a sketch that you enclosed, and you ask for confirmation of this interpretation.

We are unaware of any interpretation of this nature. The requirements for the provision and location of clearance lamps on wide boat trailers remain those set forth in Tables I and II of Standard No. 108, with the exceptions set forth in paragraphs S5.1.1.9, S5.3.1.1.1, and S5.3.1.4.

Sincerely,

Paul Jackson Rice Chief Counsel
