TEXT: Dear Mr. Knauff:

This is an evaluation of your school bus rear warning lamp demonstration with a pop-flash option.

I initially expected that we would have a problem with high intensity flash washing out the red lens and appearing white. Technically this is what happens and if you concentrate on it, the flash can appear white. The flash duration however was so brief and when used in concert with red in the cycle did not appear white to me. That should clear one obstacle, as white is prohibited in this type of lamp. Dual day/night intensity should not be necessary as long as you stick with red lamps.

You should also not have to restrict the pop to less than every flash, but in any case you will have to locate the discharge bulb so that the parabolic reflector and lens of the host lamp project the energy at very nearly about the H-Y point. Any large amount that occurs down at a level so as to be observed by a passenger car operator less than, let us approximate, 200 feet away would probably be objectionable to some, depending upon a number of factors that I need not go into at this point.

Generally, we have a basic concept that a signal is either required or not permitted. This keeps messages clear between vehicle operators. In this case however, I believe that we can consider this option since it is only an appendage modification of an existing warning system.

When you clear this modification with the National Highway Traffic Safety Administration compliance office and with the Minnesota Department of Education student transportation office, we would need to have a look at the finished product and your test da ta for purposes of commissioner's authorization or commissioner's approval certification depending upon the marketing approach that is possible and that you wish to take.

TEXT: Dear Mr. Hitchcock:

Please be advised I represent the above named Defendant, who was charged with the violation of Section 321.424 of the Code of Iowa, which is Sale of Lights-Approval, which basically states that no person shall have for sale, sell or offer sale for use upon or as a part of the equipment of a motor vehicle, trailer, or semitrailer, or use upon any such vehicle any headlight, auxilary or fog lamp, rear lamp, signal lamp, or relfector, which reflector is required hereunder, or parts of any of the foregoi ng which tend to change the original design or performance, unless of a type which has been submitted to the director and approved by the director.

The bottom line herein is the above named Defendant had headlight covers such as described in the information I have enclosed, which is pages 210 and 211 from an auto parts catalog.

On September 23, 1988, I wrote to Ruth Skluzaceek, Director of Vehicle Registration Office, Lucas State Office Building, Des Moines, Iowa 50319 to inquire whether or not the headlight covers above described are approved by the State of Iowa, as Sectio n @ 321.428 of The Code of Iowa authorizes the Director to approve or disapprove lighting devices and to issue and enforce rules establishing standards and specifications for the approval of such lighting devices, their installation, adjustment and aimin g. This matter was taken up with the department on October 10, 1988, I received response from the Iowa Department of Transportation, Jody Johnson, Administrative Officer, Vehicle Registration, Motor Vehicle Division, citing Chapter 450 of the Iowa Admin istrative Code, Rule 450.1(321) which states that whenever the Code of Iowa requires the Department to establish standards for motor vehicle equipment or to approve types of motor vehicle equipment, the Department shall consider the item approved or stan dard established if it complies with applicable Federal Motor Vehicle Safety Standards and 49CFR Parts 501-590 (October 1, 1987), stating that the headlight covers in question met Federal Standards then they would qualify under Iowa Law.

Ms. Johnson further went on to suggest that I contact you concerning my question, a copy of Jody Johnson's letter of October 10, 1988, being enclosed for your reference.

Therefore, I am wondering as to whether or not these headlights or covers are approved by the U.S. Department of Transportation, National Highway Traffic Safety Administration Standards, and, if so, would you please be so kind as to set forth the fact these headlight covers are an approved device. If they are not so approved, please kindly so state.

I await your response.

Thank you very much.

Yours very truly,

ATTACHMT: LETTER DATED 06-2-88 RE DOT REQUIREMENTS FOR TESTING OF SEATS (AUTOMOTIVE, TRACK, BUS, MASS TRANSIT); [OCC-2136; VCC-201]

TEXT: This responds to your letter in which you made several observations about dynamic testing requirements generally in our safety standards. I am pleased to have this opportunity to explain those requirements for you.

You began by observing that this agency has been moving to replace static testing requirements (tests in which individual vehicle components are subjected to specified levels of slowly applied force in a laboratory test) with dynamic testing requirements (e.g., tests in which a vehicle is crashed into a barrier and anthropomorphic test dummies are used to measure the protection provided by the vehicle to occupants in a crash). You then suggested that there were several potential difficulties or misinte rpretations that could arise with dynamic testing.

First, you asked which of the several standardized human physical dimensions should be used to determine if a vehicle complies with our safety standards that refer to a specified percentile child or adult. For instance, section S7.1.1 of Standard No. 20 8, Occupant Crash Protection (49 CFR @ 571.208) requires the lap belt portion of a seat belt assembly to adjust to fit persons whose dimensions range from a 50th percentile 6 year old child to a 95th percentile adult male, while the shoulder belt portion of a seat belt assembly must adjust to fit persons whose dimensions range from a 5th percentile adult female to a 95th percentile adult male.

When our regulations refer to a specific size for a vehicle occupant, the regulations also clearly specify the dimensions and weights of the vehicle occupants to which we are referring. Section S7.1.3 of Standard No. 208 sets forth the critical weights and dimensions of all vehicle occupants referred to in that standard. The critical weights and physical dimensions for all of the anthropomorphic test dummies used to measure compliance with our safety standards are set forth in 49 CFR Part 572, Anthrop omorphic Test Dummies.

Second, you noted that testing facilities will conduct crash testing, but will not certify those results. This practice on the part of the testing

facilities is consistent with the requirements of the National Traffic and Motor Vehicle Safety Act (the Safety Act; 15 U.S.C. 1381 et seq.). Section 114 of the Safety Act (15 U.S.C. 1403) explicitly requires every manufacturer to certify that each of i ts vehicles or items of equipment conforms to all applicable safety standards. Hence, regardless of how a testing facility presents test results to a manufacturer, it is the manufacturer of the product, not the testing facility, that is statutorily resp onsible for certifying that each of its products complies with all applicable safety standards.

Third, you stated that "laws requiring certification usually do not require the actual crash test to be performed." You are correct to the extent that you are suggesting that the Safety Act does not require manufacturers to conduct any testing before cer tifying that its product complies with all applicable safety standards. The Safety Act requires only that the manufacturer exercise due care in certifying its products compliance with the safety standards. It is up to the individual manufacturer in the first instance what data, test results, computer simulations, engineering analyses, or other information it needs to enable it to certify that each of its products comply with all applicable safety standards.

However, for purposes of enforcing the safety standards, this agency conducts spot checks of products after they have been certified by the manufacturer. NHTSA purchases the products and tests them according to the procedures specified in the applicable standard. If the standard specifies a crash test, NHTSA conducts the crash test according to the specified procedures.

Fourth, you asked how you could obtain a copy of the Society of Automotive Engineers (SAE) Recommended Practice J833. This and all other SAE materials can be obtained by writing to: Customer Service Department, Publications Group, SAE, 400 Commonwealth Drive, Warrendale, PA 15096-0001. The SAE's Customer Service Department can also be contacted by telephone at (402) 776-4970.

Fifth and finally, you suggested that the formula used to calculate the head injury criterion (HIC), set forth in sections S6.1.2 and S6.2.2 of Standard No. 208, is relatively complex, so the HIC could be miscalculated. It is true that any mathematical calculation can be performed incorrectly. Nevertheless, the formula for calculating the HIC yields only one correct result for any set of variables. This agency has not experienced any difficulties in calculating the proper HIC from any test results, a nd is not aware of any difficulties that have been encountered by any manufacturers in making such calculations. Hence, we do not believe there are any problems associated with the HIC formula.

I hope this information is helpful. If you have any further questions or need additional information in this area, please feel free to contact me.

TEXT: Dear Mr. Momboisse:

Your letter of May 19, 1988, to the General Counsel of the Department of Transportation has been forwarded to this Office for reply. You request a waiver "exempting the Hummer vehicle from the Federal Motor Vehicle Safety Standards (FMVSS) when purchase d directly from the manufacturer, AM General Corporation."

This response is based upon the information contained in your letter, and upon information my staff has obtained in telephone conversations with Ed Butkera of AM General Corporation, manufacturer of the Hummer, relating to its compliance with the Federal motor vehicle safety standards, and Gary Runyon of the Border Patrol, relating to the mission of that agency and the role the Hummer plays in it. According to our information, the Hummer is a vehicle which was developed specifically for, manufactured f or, and sold exclusively to, the U.S. Army. The Border Patrol has bought Hummers from the Army because of certain features it finds advantageous in its operations, and its expanded missions involving interdiction of drugs. The principal reasons for you r request are (1) that the Border Patrol desires to buy Hummers equipped with an assembly line addition (a central tire inflation system) is not incorporated on the Hummers sold to the Army, and (2) that, by buying directly from AM General Corporation, t he Border Patrol will save $ 5,000 per vehicle, as the price of Army Hummers reflects the added expense of amortized development costs.

This agency has jurisdiction over "motor vehicles" as that term is defined by 15 U.S.C. 1391(3). If a vehicle is not a "motor vehicle," then the Federal motor vehicle safety standards do not apply to it. The exclusion of military vehicles from applicab ility of the safety standards in 49 C.F.R. 571(a), which you quoted, is operative only if those vehicles would otherwise be "motor vehicles" required to comply with the standards.

2

Under 15 U.S.C. 1391(3), a "motor vehicle" is "any vehicle driven or drawn by mechanical power manufactured primarily for use on the public streets, roads, and highways. . . ." The agency has interpreted this definition to exclude such vehicles as minibi kes, golf carts, all-terrain vehicles, single seat racing cars used on closed courses, airport crash and rescue vehicles, and farm tractors. On the other hand, the agency has included in the definition farm trailers which haul produce over the public ro ads to processing centers, stock cars modified for racing unless such modifications are so extensive that the vehicle can no longer be licensed for use on the public roads, and vehicles capable of use both on rails and the public roads.

You have informed us that the Hummer will "generally only be used on public highways to travel between stations and assigned duty areas." However, you have also informed us that this will constitute approximately 30% of its operational time. Were we to c onsider this factor alone, we could not conclude that the Hummer was not a "motor vehicle." However, there are further factors that make the proper classification of the Hummer a close question. The Hummer was developed as a vehicle for military operati ons and not for civilian applications, its manufacturer does not advertise or sell it for civilian purposes, and its configuration is such that it probably could not be licensed for use on the public roads without modification of some of its original mil itary specifications.

Resolution of this question is not necessary since the mission and method of operation of the Border Patrol provide a separate basis for concluding that the Hummers to be purchased by the Border Patrol are not subject to the FMVSS. We understand that on e of the missions of the Border Patrol is to act as an agency of national security in protection of the country's borders to ensure that persons and goods enter and exit only through official Customs and Immigration stations, and that this role has becom e of paramount importance in the "war against drugs." In this enforcement effort, the Hummers of necessity carry firearms such as the M-14 and M-16 rifles which the Army Hummer carries, can be equipped with military communications equipment enabling them to serve as command posts, and carry certain military equipment used for electronic interception and sensing movement. It further appears that in this mission the Border Patrol is not only equipped like a component of the Armed Forces of the United Sta tes, but also is trained and functions in many respects that are similar to such a component. Accordingly, for the purposes of applying the exclusionary phrase of 49 CFR 571.7(a), it is appropriate to regard the Border Patrol as being akin to a componen t of the Armed Forces of the United States. In consideration of the foregoing, the National Highway Traffic Safety Administration has concluded that AM General Corporation will not be in violation of the

3

National Traffic and Motor Vehicle Safety Act if it manufacturers and sells Hummers to the Border Patrol for its use as described in your letter.

Maserati Automobiles Incorporated (MAI) requests an interpretation of the requirements in S.4.1.3. of FMVSS 208 concerning the minimum annual production of passenger cars that must be equipped with passive restraints. More specifically, because the s tandard applies only to vehicles produced for sale in the U.S. and because, under Section 108 (b) (5) of the Safety Act, the standard does not apply to vehicles intended solely for export, MAI assumes that if, during a "phase-in" period, vehicles that we re previously imported into the U.S. by MAI are exported to Canada (where we have one dealer) would be deducted from the U.S. production total to arrive at the base figure to which the phase-in percentage would apply.

We would greatly appreciate your confirming this interpretation as soon as possible, so that we can report under 49 CFR Part 585.

TEXT: This responds to your letter asking for further clarification of a March 1, 1985 letter to you from the Chief Counsel of this agency. Your company is marketing a process in which parallel grooves are ground into the lower portion of the windshield of ve hicles. In our March 1, 1985 letter to you, we set forth a general description of the requirements that would apply if the process were used on new vehicles or new windshields sold as an item of replacement equipment, and those requirements that would a pply if the process were used on vehicles that had already been sold to the first purchaser or windshields that were already installed in vehicles. Your letter explains that your company now uses this process only on vehicles that have already been sold to a first purchaser and windshields already installed in vehicles. You asked for clarification of several issues in your letter.

1. Your company has obtained test reports from two laboratories on the process of grinding these parallel grooves into the lower portions of windshields. One of these reports specifically states that windshields with these grooves fully comply with all requirements of Standard No. 205, Glazing Materials (49 CFR $ 571.205). You asked whether the steps your company has taken are "sufficient to show compliance with Standard No. 205."

Response: The National Traffic and Motor Vehicle Safety Act (15 U.S.C. 1381 et seq.) does not permit this agency to assure any person or entity that its products or processes comply with all applicable requirements or to "approve" some product or process . Instead, section 114 of the Safety Act (15 U.S.C. 1403) requires the manufacturer itself to certify that its products comply with all applicable safety standards.

Standard No. 205 requires that the windshields installed in new vehicles and new windshields sold as replacement equipment to meet certain performance requirements, and requires the windshield to be certified as complying with those requirements. You ha ve stated that your company's process of grinding grooves into windshields will not be used on new

vehicles or new windshields. Standard No. 205 does not require that windshields be certified as continuing to comply after being treated by aftermarket processes, such as your company's grooving process. Accordingly, if your grooving process is used on ly in aftermarket applications, your company is not required to certify that those windshields continue to comply with Standard No. 205 after grooves have been ground into the windshield. However, continued compliance with Standard 205 is important, for a different reason, discussed below.

Even though Standard No. 205 does not directly apply to your process, and your company does not have to certify continued compliance with Standard No. 205, section 108(a)(2)(A) of the Safety Act (15 U.S.C. 1397(a)(2)(A)) does impose an obligation on manu facturers, distributors, dealers, and repair businesses including your licensees, with respect to aftermarket processes. That section provides: "No manufacturer, distributor, dealer, or motor vehicle repair business shall knowingly render inopperative i n whole or in part any divice or element of design installed on or in a motor vehicle . . . in compliance with an applicable Federal motor vehicle safety standard . . ."

In this case, a number of elements of design have been installed in the windshield of motor vehicles in compliance with Standard No. 205, including impact and penetration resistance, optical deviation limitations and limitations on visual distortion. If grinding grooves into the windshield by means of your company's process would cause the windshield to no longer comply with these or some other requirements of Standard No. 205, grinding the grooves into the windshield would be a violation of the "rende r inoperative" provision of the Safety Act.

The Safety Act imposes a responsibility on manufacturers, distributors, dealers, and repair businesses to ensure, in the first instance, that none of the aftermarket operations they perform will result in a violation of the "render inoperative" provision . NHTSA reexamines the initial determinations made by any of these parties only in the context of an enforcement proceeding. If your company has concluded that the test reports enclosed with your letter show no "rendering inoperative" when grooves are ground into windshields, NHTSA will not express any view on that conclusion unless and until the agency begins some enforcement proceeding to examine this grooving process.

In keeping with this statutory scheme, neither our March 1, 1985 letter nor this letter expressed any agency opinion as to whether dealers using your company's process to grind grooves into windshields of vehicles would or would not render inoperative th e windshield's compliance with Standard No. 205. Instead, both these letters are intended only to alert your company to the elements of design that might be rendered inoperative by grinding grooves in windshields by your process.

2. Would it be possible for your company to indicate on the windshields in which you grind these grooves that your company has "shown compliance with Standard No. 205," for example, by affixing a clear sticker to that effect?

Response: As explained above, only new windshields or windshields installed in new vehicles must be certified as complying with Standard No. 205. There is no requirement that windshields subjected to

aftermarket processes be certified as still complying with the standard. If your company voluntarily chooses to provide some indication of continuing compliance, it is free to do so. NHTSA has long said that the only restriction on voluntary markings i s that those markings must not obscure or confuse the meaning of any required markings on the product. Assuming that your voluntary markings will not obscure or confuse the meaning of the required markings on the windshield, the voluntary marking would not violate any Federal requirements. You should be aware, however, that some State laws restrict stickers and other items placed on automobile windshields.

3. Is your company required to show continuing compliance with Standard No. 212, Windshield Mounting (49 CFR $ 571.212) for vehicles whose windshields have grooves ground in accordance with your company's process?

Response: The vehicle manufacturer is responsible for certifying that each of its new vehicles complies with the requirements of Standard No. 212. There is no obligation for any person that performs aftermarket operations on the vehicle or its windshiel d to certify continuing compliance with Standard No. 212.

As explained above, the only requirement applicable to aftermarket operations on a vehicle is that manufacturers, distributors, dealers and repair businesses are prohibited from "rendering inoperative" a vehicle's compliance with any safety standard, inc luding Standard No.212. Standard No. 212 requires a vehicle to retain a specified percentage of the windshield periphery. To avoid violating the "render inoperative" prohibition, I suggest that you carefully examine the process by which grooves are gro und into windshields and determine whether the installation of those grooves in accordance with your company's process would result in the vehicle no longer complying with Standard No. 212. Your company is obliged to determine that this grooving process will not result in a rendering inoperative violation with respect to Standard No. 212. As explained above, NHTSA will not express any views about your company's determination except in the context of an enforcement proceeding.

I hope this information is helpful. Please let me know if you have any further questions on this subject.
