TITLE: FMVSS INTERPRETATION

TEXT: This responds to the Alfred Teves GMBH (Teves) petition of April 9, 1976, for amendment of S5.2.1 of Standard No. 106-74, Brake Hoses, to eliminate the striping requirement in the case of hose used in assemblies that have "keyed" end fittings at both ends. We interprete "keyed" fittings to mean those that can be installed in only one (or possibly several) orientation(s) to the vehicle.

This is to advise you that the National Highway Traffic Safety Administration has determined to grant Teves' petition with regard to hose that is assembled into an assembly whose fittings permit their installation into the vehicle in only one orientation. Detailed reasons for the limitations expressed in this letter will accompany any notice that proposes this change.

You should understand that our commencement of a rulemaking proceeding does not signify that the rule in question will be issued. A decision as to the issuance of the rule is made on the basis of all available information in accordance with statutory criteria.

Your letter incorrectly characterized the amendment of S5.2.2 that was proposed in Notice 19 of docket 1-5 (40 FR 55365, November 28, 1975) and made final in Notice 21 (41 FR 28505, July 12, 1976). The amendment only stated that the labeling required on hose need not be present after the hose has become part of a brake hose assembly or after it has been installed in a motor vehicle. The conclusion in the second paragraph of your letter that ". . . brake hose does not require labelling according to S5.2.2. . ." is therefore incorrect.

With regard to your comments on Standard No. 116, Brake Fluids, I assume that you were referring to the agency's proposed definition of "brake fluid" published on December 5, 1975 (40 FR 56928). I also assume that the phrase "polychloroprene (CR) brake hose inner tube stock" in the proposed definition led you to conclude that only polychloroprene inner tube stock would be allowed for brake hose construction. This is incorrect. All of the materials specified in the definition, including SBR, EPR, CR, and NR, are considered suitable for use in brake hoses.

Sincerely,

April 9, 1976 PETITION

Ref.: Amendment to Standards FMVSS 106 49 CFR Part 571, Docket No. 1-5, Notice 19

In notice 19 DOT has proposed that S.5.2.2 should be altered, in that, the labeling information could be eliminated as soon as the brake hose becomes a brake hose assembly. According to S.5.2.1 the hose manufacturer was given the option to interrupt the 2 stripes by information according to S.5.2.2 and additional information.

We understand this DOT recommendation to mean that in future permanent brake assemblies do not require labelling information so long as the manufacturer documents all hoses before assembly. i.e the brake hose does not require labelling according to S.5.2.2 because the hoses are documented and can thereby always be identified

Notice 19 indicates that our interpretation in assuming the above is correct. Provided that our interpretation is correct then, we are in agreement with the proposed amendment and endorse it.

Although the deleting of S.5.2.2 for brake hoses used in permanent brake hose assemblies is apparent, the requirement S.5.2.1 which states: "each hydraulic brake hose shall have at least two clearly identifiable stripes" is still required for brake hoses not part of a brake hose assembly.

The stripes are a visible indication of hose twisting during assembly. We are convinced that the brake hose marking would be unnecessary if the brake hose assembly could, by mechanical means, be prevented from twisting during and after installation. This mechanical means would eliminate the necessity of having two marking stripes.

Taking into account the foregoing we petition that S.5.2.1. should be amended to require the two marking stripes only when this mechanical means is not a part of the brake hose assembly in both ends.

We propose that FMVSS 106 should be amended as follows:

S.5.2.1 Each hydraulic brake hose, with the exception of those brake hose assemblies which have keyed ends (preventing twisting during and after instalation), shall have at least two clearly identifiable stripes of at least one-sixteenth of an inch in width, placed on opp. . . .

This amendment would prevent the unnecessary duplication of safety requirements thereby keeping costs to a minimum.

Ref.: FMVSS 116 49 CFR 571 116 Docket No. 71-13

The formulation of the definition S.4. suggests that brake hose inner tube stock must be of polychloroprene (CR). We have been using SBR for our inner tubes for years with excellent results. Naturally they meet the USA Standard FMVSS 106 and also have US approval through AAMVA based on a certificate from the independent test laboratory "ETL".

As the US standards FMVSS 106 has never objected to our brake hose material with regards to its properties and suitability for use in its designed environment we fail to understand why SBR together with the other materials EPR, EPDM, buthyl etc. are not considered suitable for use as brake hose inner tube.

May we suggest therefore that the definition S4 be formulated in such a way that this point is more clearly defined. In our opinion this should be changed to cover all materials which have a stable resistance to brake fluid.

Yours faithfully -- ALFRED TEVES GMBH

TITLE: FMVSS INTERPRETATION

TEXT: This is in reply to your letter of April 4, 1974, concerning your request for an exemption from the roof emergency exit requirements (S5.2.1) of Motor Vehicle Safety Standard No. 217 (49 CFR 571.217). We had denied an earlier request on March 27, 1974, following your letter to us of February 13, 1974.

We must again deny your request. The Federal motor vehicle safety standards which apply to motor vehicles (some apply to equipment only) specify safety requirements which apply to vehicle types generally (passenger cars, trucks, buses, etc.) and must of necessity be based on the use to which such vehicle types are generally put. The NHTSA has determined through the administrative rulemaking process that buses, including buses for use in urban environments, must have a roof emergency exit when a rear exit can not be installed due to the configuration of the bus. In most cases, including many urban situations, the roof exit can be an important safety feature, particularly when the bus is overturned on a side. While we do not dispute the facts you present, we view the situation as unsual, and not a suitable basis for modifying a requirement applicable to every urban bus. Our regulations do not permit exemptions from requirements for buses sold to one party.

However, under the National Traffic and Motor Vehicle Safety Act (15 U.S.C. @@ 1391 et seq.) under which Standard No. 217 is issued, a vehicle need not conform to a Federal motor vehicle safety standard after its sale to its ultimate user. Consequently there is no Federal prohibition to your modifying or eliminating the roof exits in these buses if you wish, after you receive them from the manufacturer.

In reply to your letter dated March 27, 1974, N40-3 (MPP)

Subject: Roof emergency exit (S5.2.1) Motor Vehicle Safety Standard #217

I am sure that you are becoming increasingly familiar with problems of making buses safer; this has also been our prime concern. In your letter you stated in order that the requirements be modified, there must be a showing, that their cost is unreasonable in terms of the safety benefits achieved. Again we are not concerned with the cost ratio, safety is our and your prime concern. About the abuses which the buses are subject to, you must take into account exactly, that which is going on in the buses. Bus seats being torn off there mounting, then seat cushions being thrown out of the window, window frames being dismantled and thrown out, screws from internal panels being removed and panels thrown out of buses, glass being broken, whereby cost and replacing is almost impossible, seat being cut up so as to be unrecognizable.

You speak of possible alternative steps taken to develop designs that will minimize the tampering with. I would like at this time to say that it is my opinion, in order to achieve the safety that we are both looking for, we should first develop the means to modify this condition that I presently see as a very dangerous and hazardous condition. Visualize the roof hatch being opened and the pupils boosting each other thru this hatch. What do you think will happen when the driver discovers this? immediately he will hit the brake pedal and where do you think the pupils will wind up? also, think of the traffic following. The hitting of the brake pedal will not be deliberately on our drivers part.

In an accident such as a roll over the bus can land on one of four sides. If it lands right side up that is on four wheels, there will be one entrance and one exit door. Eight large picture frame windows, if it lands on the left side. It will have one entrance door and one exit door and four large picture frame windows. The entire front windshield and the entire rear windshield, which are set in rubber can be kicked out very readily in any of the four positions, making an opening large enough to walk out in a standing position, if it lands on the right side there are four large picture frame windows. Also remembering the front and rear windshields, the most important part to remember, is in a roll over the sides of the bus will be pushed in there by buckeling up the roof. Because of the structure of the vehicle which I believe will distort the roof hatch and make it inoperable. This has been proven to be a fact.

To give you a short resume of my experiences aroun buses, listed below are the following:

1. 42 years as Superintendent of all Equipment.

2. A graduate of Pratt Institute, Brooklyn, New York.

3. Triboro Coach Corporation operates 165 city coaches.

4. Varsity Transit Inc. which is a school bus operation only and operates 1,378 vehicles which includes 80 lift buses hydraulically operated for wheel chairs.

This resume is not intended to impress you, or that I am an authority on the subject, but rather to show that I am familiar with the importance of that which you seek.

TITLE: Re: Alternative To 9005 & 9006 Bulbs:

ATTACHMT: Attached to 1/27/95 letter from Philip R. Recht to Deborah K. Nowak-Vanderhoef (A43; Std. 108)

TEXT: General Motors Corporation (GM), in conjunction with Osram Sylvania Inc., has developed alternatives to two existing HB3 and HB4 (9005 and 9006) bulbs approved for automotive use in FMVSS 108, Lamps, Reflective Devices, and Associated Equipment. The alt ernative bulbs have a different base configuration than the currently approved bulbs, but in all other ways are identical. The alternative configuration would allow packaging flexibility while still maintaining all photometric/output characteristics of the currently approved 9005-6 bulbs.

Since the alternative bulbs improve packaging flexibility without affecting the output of the lamps, GM would like the alternative bulbs to be interchangeable with the currently approved 9005-6 bulbs. We request your Office's guidance as to the most app ropriate method for seeking approval of the alternative bulb configurations.

BACKGROUND

The currently approved 9005-6 bulbs have bases that form right angles (see attachment 1). This configuration provided the most appropriate means of meeting automotive packaging considerations when these bulbs were originally approved.

Since then, however, aerodynamics and styling have dramatically affected the construction of the front of vehicles. In some instances it has become very difficult to package the currently approved 9005-6 bulbs. In addition, the bulbs can be difficult t o access for replacement.

It occurred to GM and Osram Sylvania that the situation could be improved with a simple modification to the existing 9005-6 bulbs. By straightening the base of these bulbs (see attachment 2), while keeping all other design criteria the same, the packagi ng could be improved without affecting any performance characteristics of the bulbs.

Since the new configurations are identical with the currently approved bulbs in all ways other than the bases, GM believes it appropriate to allow them to be interchangeable with the existing 9005-6 bulbs. This would further enhance packaging flexibilit y by allowing alternative configurations which might be better suited to late program design changes.

The alternative bulbs will have little or no affect on the consumer. A vehicle will come equipped with one of the bulb configurations, and the operator's manual will reference the appropriate configuration. If the alternative bulb is inadvertently purc hased for replacement, it could be used in all cases except in the highly unlikely circumstance that the vehicle packaging is so restrictive as to prevent the bulb from being inserted. Once inserted it is designed to perform identically to the bulb that has been replaced, regardless of the configuration of the base. In the unlikely case that the bulb could not be inserted because of restrictive packaging, the owner would need only to return the inappropriate bulb for the bulb approved for his or her v ehicle - a situation that exists today.

To further minimize any confusion on the part of the consumer, we would recommend that the alternative bulbs have a unique identifier to distinguish them from the current bulbs. This could easily be accomplished by adding a character to the codes of the existing bulb. For example, HB3S and HB4S could be used to identify the alternative bulb configurations of HB3 and HB4.

APPROVAL PROCESS

GM believes there are three possible methods that could be used for seeking approval of the 9005-6 bulb alternative configurations. They are

1. Seek approval of the alternative configuration through 49 CFR Part 564.

The language of Part 564 suggest that we would be unable to maintain interchangeability between alternative configurations and the currently approved 9005-6 bulbs. We understand these provisions were adopted to prevent interchangeability between bulb s with different photometric output, since such interchangeability could have drastic effects on headlamp beam patterns. This, however, is not the case with the alternative bulbs GM proposes. Except for the bases, they are identical in all respects to the currently approved 9005-6 bulbs. Therefore, there is no photometric difference between the two sets of bulbs, and hence, no safety concern.

Still, the wording in Part 564 would suggest that the alternative bulbs we developed would require a new or different connector than 9005-6. We do not believe that this is appropriate in this instance, and seek clarification of whether Part 564 direc tly applies to this circumstance.

2. Petition for FMVSS 108 rulemaking to allow new bulb configurations as alternatives to the currently approved 9005-6 bulbs.

While this appears to be a valid method for obtaining approval of the proposed configurations, it is our understanding that NHTSA is planning to transfer all bulb specifications from the body of FMVSS 108 into Part 564. Therefore, we believe that the agency may not welcome a petition to amend FMVSS 108 to comprehend additional bulbs (or new bulb configurations).

3. Request that the currently approved 9005-6 bulbs be placed in Part 564 with the alternative configurations included on the drawing. Attachment 3 contains a draft of what the drawings might look like.

Please confirm which method the agency believes is most appropriate for seeking approval of the new alternative bulbs which, as described above, except for their bases perform identically to the currently approved 9005-6 bulbs.

Dear Senator Graham:

On October 6, 1994 I wrote to you about the proposed bill before the Senate in Puerto Rico, with the regards to the importation of used tires.

In these days of the N.F.T.A. and G.A.T.T. agreements it seams that the new tire manufacturers are pressing for a restraint of trade by pressing for the passage of this bill.

We have contacted the U.S. Department of Commerce they in turn have directed us to the National Highway Safety & Traffic Administration. We had written them on November 6, but as of today we have not gotten any response. We would like to get a copy of the laws regarding tire tread depth here in the U.S. and in Puerto Rico and we would like to know if they have jurisdiction in Puerto Rico. We need your help in getting this vital information.

If this bill passes it will surely mean the end of our industry in Puerto Rico

Dear Dr. Martinez:

Used Tire International, INC. is an Exporter of Quality Used Tires Worldwide. There is a very serious situation that has arisen in Puerto Rico in regards to the importation of Used Tires, a proposed bill is before the senate there that would require all Used Tires being imported to have a minimum 5/32" tread depth and a tax of $ 10.00 each. The tread depth of 5/32" is 3/32" more than the 2/32" that is required by U.S. law. Does the NHTSA have jurisdiction over these laws in Puerto Rico or does the Pue rto Rican Senate control the regulations over highway safety.

If this proposed Bill is passed this would mean the end of the Used Tire industry on the island. This is an industry that many people count on there because many people cannot afford to purchase new tire which I will add some new tires only have 4/32" t read. To inact a law that would require a Used Tire to have more or as much tread as a new tire would further hurt our industry.

ATTACHMT: Attached to letter dated 11/5/93 from Judith Jurin Semo to John Womack (OCC 9287)

TEXT:

This responds to your request for NHTSA's determination that certain former East German military trucks, ZIL model 131, are not motor vehicles, and exempt from the Federal Motor Vehicle Safety Standards (FMVSS). We are unable to make such a determination. As explained below, a ZIL model 131 truck imported into the United States is considered a "motor vehicle" for purposes of the National Traffic and Motor Vehicle Safety Act (Safety Act) (15 U.S.C. 1391 et seq.), and is subject to the FMVSS.

Your letter explained that a client plans to import over 500 ZIL model 131 trucks into the U.S. Apparently, your client plans to modify the trucks in the U.S. to use for nonmilitary purposes. Your client intends to send most of the modified trucks to buyers in other countries, but plans to sell some of the trucks in the U.S. Your letter states: "... (S)ome ZIL vehicles may be modified to meet DOT/NHTSA and EPA standards in order to satisfy those buyers who require vehicles conforming to those standards."

Under the Safety Act, any "motor vehicle," whether new or used, that is imported into the United States for sale in this country must be brought into conformity with all FMVSS that applied at the time of its manufacture. The question that must be answered is whether the ZIL 131 trucks, at the time of importation, would be considered "motor vehicles."

"Motor vehicle" is defined at section 102(3) of the Safety Act (15 U.S.C. 1391(3)) as:

(A)ny vehicle driven or drawn by mechanical power manufactured primarily for use on the public streets, roads, and highways, except any vehicle operated exclusively on a rail or rails.

NHTSA has interpreted this language as follows. Vehicles that are equipped with tracks or are otherwise incapable of highway travel are not motor vehicles. Further, vehicles designed and sold only for off-road use (such as airport runway vehicles and underground mining devices) are not considered motor vehicles, even though they may be operationally capable of highway travel. Vehicles that have an abnormal body configuration that readily distinguishes them from other highway vehicles and a maximum speed of 20 miles per hour (mph) are not considered motor vehicles, because their use of the public roads is intermittent and incidental to their primary intended off-road use.

On the other hand, vehicles that use the public highways on a necessary and recurring basis are motor vehicles. For instance, a utility vehicle like the Jeep is plainly a motor vehicle, even though it is equipped with special features to permit off-road operation. If a vehicle's greatest use will be

off-road, but it will spend a substantial amount of time on-road, NHTSA has interpreted the vehicle to be a "motor vehicle." Further, the agency has determined that a vehicle such as a dune buggy is a motor vehicle if it is readily usable on the public roads and is in fact used on the public roads by a substantial number of owners, regardless of the manufacturer's stated intent regarding the terrain on which the vehicle is to be operated.

Applying the above criteria, and based on the information in your letter, the ZIL model 131 trucks are motor vehicles. You state that potential U.S. buyers would require vehicles that meet the FMVSS. This suggests that U.S. vehicle owners intend to use the ZIL model 131 trucks as they would other motor vehicles, on the public roads. Judging from your photographs, the trucks do not have abnormal body configurations that distinguish them from other vehicles on the road. You stated that the trucks have a top speed of almost 50 miles per hour, a speed suitable for public roads. These facts suggest that the ZIL model 131 truck is designed and intended to be routinely used on the public roads, and should be classified as a motor vehicle.

Assuming your client is still interested in importing the ZIL 131 trucks for resale in the U.S., the Imported Vehicle Safety Compliance Act requires that the agency determine that the vehicles are capable of conversion to meet the FMVSS, and that the trucks be imported by a "registered importer." The agency makes determinations upon the basis of a petition by the manufacturer or registered importer (or upon its own volition). A "registered importer" is one whom NHTSA has recognized as capable of converting vehicles to meet the FMVSS. If you would like further details on eligibility determinations and import procedures, please let us know and we shall be pleased to provide them.

The Safety Act also addresses trucks your client wishes to import into the U.S. for modification for export. Under section 108(b)(3) of the Safety Act, the FMVSSs do not apply to vehicles intended solely for export. Thus, trucks brought into the U.S. for modification for export are not subject to the FMVSSs. Under 49 CFR S591.5, the importer would file a declaration under S591.5(c), that the vehicle does not comply with all applicable Federal motor vehicle safety, bumper, and theft prevention standards, but is intended solely for export.

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

ATTACHMT: 9/01/95 (est.) letter from Dorothy Jean Arnold, M.D., to Safety Administration

TEXT: This responds to your letter asking whether the air bags in your car can be disconnected. You explained that you are physically impaired by the effects of osteomyelitis, a disease of the bones; cannot use a seatbelt with comfort; and were "granted dispe nsation from such usage several years ago." In a telephone conversation with Richard Reed of this agency, you indicated that you are 74 years old 45 feets three inches tall, and must sit close to the steering wheel because of your medical condition.

As explained below, our answer is that NHTSA will not institute enforcement proceedings against a repair business that disconnects an air bag on your vehicle to accommodate your condition.

Standard No. 208, Occupant Crash Protect [Illegible Word] requires that cars be equipped with automatic crash protection at the front outboard seating positions. The air bags in your car were installed as one means of complying with that requirement. T he removal or deactivaxion of one of those air bags by a vehicle dealer is governed by a provision of Federal law, 49 U.S.C. @ 30122. The section provides that provi

A manufacturer, distributor, dealer, or motor vehicle repair business may not knowingly make inoperative any part of a device or element of design installed on or in a motor vehicle or motor vehicle equipment in compliance with an applicable motor vehicl e safety standard.

However, in limited situations in which a vehicle must be modified to accommodate the needs of a person with a particular disability or a person's special medical needs, NHTSA has in the past stated that it would consider violations of the "make inoperat ive" prohibition as purely technical ones justified by public need, and that it would not institute enforcement proceedings.

I would like to caution you that both safety belts and air bags are very important items of safety equipment. Safety belts are the primary means of occupants restraint, and work in all types of crashes. NHTSA estimates that in 1994, safety belts saved almost 9,200 lives and prevented more than 211,000 moderate to critical injuries. The combination of wearing safety belts and having an air bag installed at a seating position provides vehicle occupants with maximum safety protection in all types of cra shes. Also, air bags are designed to offer some protection even when safety belts are not used. Since 1987, air bags are estimated to have saved 911 lives.

NHTSA strongly encourages vehicle occupants to wear their safety belts, since we are concerned about the much higher safety risk faced by unbelted occupants. We understand, however, that you cannot wear your safety belt for medical reasons, and that you are concerned about a possible safety risk from the air bag in such a situation.

While air bags have an impressive overall performance record and are designed to provide some protection even for unbelted occupants, NHTSA has become aware of situations in which current air bags have undesired side effects. These include situations in which an air bag appears to have contributed to serious injuries and even death to vehicle occupants, in minor-to-moderate severity crashes. Information indicates that an air bag might pose a risk of serious injury to unrestrained small statured and/or older people, in particular. I note that NHTSA has recently issued a request for comments (copy enclosed) concerning the agency's actions to minimize the adverse side effects of air bags and to invite the public to share information and views with the a gency.

Since your disability prevents you from wearing your safety belt, and given your age and size, the disability places you in a situation where there may be a risk of serious injury from the air bag. While this particular risk can be addressed by disconne cting the air bag, there are trade-offs: Disconnecting the air bag subjects you to a higher risk in crashes, especially higher-speed crashes, where the air bag would provide protection. We urge you to carefully weigh the trade-offs in making your decisi on.

If you decide that the risk to you from the air bag offsets the potentially life-saving benefits of the air bag, and you wish to have your air bag deactivated, we would regard the deactivation a purely technical violation of the "make inoperative" prohib ition justified by public need. Accordingly, we would not institute enforcement proceedings against any person listed in section 30122 who deactivated the air bag. I would recommend that the manufacturer of the vehicle and/or air bag be consulted on th e safest way to disconnect the air bag. I also note that the air bag should only be disconnected from a position where you would be seated. In addition, I strongly encourage you to ensure that every person in your vehicle who can use his or her safety belt does so.

I want to add a caution. The purpose of the "make inoperative" prohibition is to ensure, to the greatest degree possible, current and subsequent owners and users of your vehicle are not deprived of the maximum protection afforded by the vehicle as newly manufactured. Accordingly, if you were to sell your vehicle later, we urge that the air bag be reactivated for the subsequent driver.

I hope that this letter resolves your problem. If you have any other questions, please contact Edward Glancy of my staff at this address or by phone at (202) 366-2992.

TEXT: Dear Mr. Bode:

This responds to your letter concerning whether 49 U.S.C. @@ 30101 et seq. (formerly the National Traffic and Motor Vehicle Safety Act) requires a motor vehicle manufacturer to ensure that its vehicle continues to comply with applicable Federal motor veh icle safety standards (FMVSSs) after the first retail purchase of the vehicle.

You specifically ask about FMVSS No. 124, "Accelerator Control Systems," and its application to a 1988 Dodge Ram 50 pickup truck. It appears from the questions you ask that corrosion developed inside the carburetor of the pickup truck at some point duri ng the life of the vehicle, such that the carburetor would not return to idle in accordance with the requirements of Standard No. 124.

You asked us to "confirm the accuracy" of a number of statements. Your first statement, concerning the application of the FMVSSs generally, is as follows:

As we understand it, former @ 108(a) (1) (A) of the National Traffic and Motor Vehicle Safety Act, 49 U.S.C. @ 30112(a), prohibits any person from manufacturing, selling or introducing into commerce any new motor vehicle unless the vehicle is in conformi ty with all applicable FMVSS. However, the Safety Act further provides that the requirement that a vehicle comply with all applicable FMVSS does not apply after the first purchase for purposes other than resale, i.e., the first retail sale of the vehicl e. Safety Act former @ 108 (b) (1), 49 U.S.C. @ 30112 (b) (1). After the first retail sale, the only provision in the Safety Act that affects a vehicle's continuing compliance with an applicable FMVSS is set forth in former @ 108(a) (2) (A), 49 U.S.C. @ 30122(b), which prohibits certain persons from knowingly rendering inoperative a device installed in a motor vehicle in compliance with an applicable FMVSS.

Your general understanding is correct. However, a manufacturer has responsibilities in addition to those in @ 30112, that may bear upon on "continuing compliance" of its vehicle. Under @@ 30118-30122 of our statute, each motor vehicle manufacturer must ensure that its vehicles are free of safety-related defects. If NHTSA or the manufacturer of a vehicle determines that the vehicle contains a safety-related defect, the manufacturer must notify purchasers of the defective vehicle and remedy the problem free of charge.

This is not to say that the development of the corrosion in the carburetor necessarily constitutes a safety-related defect. Rather, we acknowledge the possibility of such a finding in certain circumstances, such as where the corrosion developed unreason ably quickly in the vehicle and the problem was such that it could lead to crashes involving injuries or fatalities.

State law could also be relevant to this issue. For example, as part of its vehicle inspection requirements, a State could require that the accelerator control systems on vehicles "continue to comply" with the requirements of Standard No. 124.

With the above discussion in mind, I will now address your other four questions on Standard No. 124.

Question 1. We ask that NHTSA confirm that FMVSS 124 is a standard that a given vehicle must comply with only at the time of the first retail sale of the vehicle.

As explained in our answer above, your understanding is correct with regard to our requirements (49 U.S.C. @ 30112). There may be State requirements that apply.

Question 2. We ask NHTSA to confirm that if a carburetor installed in a 1988 Dodge Ram 50 pickup truck met all the requirements of FMVSS 124 at the time of the truck's first retail sale, but, after the sale, due to in-service conditions, corrosion develo ped inside the carburetor so the carburetor would not return to idle in accordance with the requirements of S5.1, S5.2, and S5.3 of FMVSS 124, that circumstance would not render the vehicle in violation of FMVSS 124.

Your understanding is essentially correct. As permitted by Federal law, Chrysler sold the truck based upon its own certification of compliance with FMVSS No. 124. That corrosion developed in the system may or may not be relevant with respect to the exi stence of a safety-related defect.

Question 3. We ask NHTSA to confirm that all of the performance standards imposed by FMVSS 124 are contained in S5.1, S5.2 and S5.3 of FMVSS 124 and that S2 headed PURPOSE does not impose any separate regulatory obligation beyond those contained in S5.

While your understanding is essentially correct, note that Standard No. 124 and other motor vehicle safety standards are minimum performance standards.

Question 4. We ask you to confirm that the performance standard set forth in FMVSS 124 does not contain any requirement relating to durability or corrosion resistance.

Standard No. 124 does not specify a test for corrosion resistance. It is unclear what you mean by "durability." The requirements of the standard must be met when the engine "is running under any load condition, and at any ambient temperature between - 4 0 degrees F. and + 125 degrees F. . ." (S5) In addition to the performance regulated by Standard No. 124, each manufacturer must ensure that its motor vehicle does not have a safety-related defect.

Washington, D.C. 20044-0407

Dear Ms. Semo:

This responds to your request for NHTSA's determination that certain former East German military trucks, ZIL model 131, are not motor vehicles, and exempt from the Federal Motor Vehicle Safety Standards (FMVSS). We are unable to make such a determination. As explained below, a ZIL model 131 truck imported into the United States is considered a "motor vehicle" for purposes of the National Traffic and Motor Vehicle Safety Act (Safety Act)(15 U.S.C. 1391 et seq.), and is subject to the FMVSS.

Your letter explained that a client plans to import over 500 ZIL model 131 trucks into the U.S. Apparently, your client plans to modify the trucks in the U.S. to use for nonmilitary purposes. Your client intends to send most of the modified trucks to buyers in other countries, but plans to sell some of the trucks in the U.S. Your letter states: "... [S]ome ZIL vehicles may be modified to meet DOT/NHTSA and EPA standards in order to satisfy those buyers who require vehicles conforming to those standards."

Under the Safety Act, any "motor vehicle," whether new or used, that is imported into the United States for sale in this country must be brought into conformity with all FMVSS that applied at the time of its manufacture. The question that must be answered is whether the ZIL 131 trucks, at the time of importation, would be considered "motor vehicles."

"Motor vehicle" is defined at section 102(3) of the Safety Act (15 U.S.C. 1391(3)) as:

[A]ny vehicle driven or drawn by mechanical power manufactured primarily for use on the public streets, roads, and highways, except any vehicle operated exclusively on a rail or rails.

NHTSA has interpreted this language as follows. Vehicles that are equipped with tracks or are otherwise incapable of highway travel are not motor vehicles. Further, vehicles designed and sold only for off-road use (such as airport runway vehicles and underground mining devices) are not considered motor vehicles, even though they may be operationally capable of highway travel. Vehicles that have an abnormal body configuration that readily distinguishes them from other highway vehicles and a maximum speed of 20 miles per hour (mph) are not considered motor vehicles, because their use of the public roads is intermittent and incidental to their primary intended off-road use.

On the other hand, vehicles that use the public highways on a necessary and recurring basis are motor vehicles. For instance, a utility vehicle like the Jeep is plainly a motor vehicle, even though it is equipped with special features to permit off-road operation. If a vehicle's greatest use will be off-road, but it will spend a substantial amount of time on-road, NHTSA has interpreted the vehicle to be a "motor vehicle." Further, the agency has determined that a vehicle such as a dune buggy is a motor vehicle if it is readily usable on the public roads and is in fact used on the public roads by a substantial number of owners, regardless of the manufacturer's stated intent regarding the terrain on which the vehicle is to be operated.

Applying the above criteria, and based on the information in your letter, the ZIL model 131 trucks are motor vehicles. You state that potential U.S. buyers would require vehicles that meet the FMVSS. This suggests that U.S. vehicle owners intend to use the ZIL model 131 trucks as they would other motor vehicles, on the public roads. Judging from your photographs, the trucks do not have abnormal body configurations that distinguish them from other vehicles on the road. You stated that the trucks have a top speed of almost 50 miles per hour, a speed suitable for public roads. These facts suggest that the ZIL model 131 truck is designed and intended to be routinely used on the public roads, and should be classified as a motor vehicle.

Assuming your client is still interested in importing the ZIL 131 trucks for resale in the U.S., the Imported Vehicle Safety Compliance Act requires that the agency determine that the vehicles are capable of conversion to meet the FMVSS, and that the trucks be imported by a "registered importer." The agency makes determinations upon the basis of a petition by the manufacturer or registered importer (or upon its own volition). A "registered importer" is one whom NHTSA has recognized as capable of converting vehicles to meet the FMVSS. If you would like further details on eligibility determinations and import procedures, please let us know and we shall be pleased to provide them.

The Safety Act also addresses trucks your client wishes to import into the U.S. for modification for export. Under section 108(b)(3) of the Safety Act, the FMVSSs do not apply to vehicles intended solely for export. Thus, trucks brought into the U.S. for modification for export are not subject to the FMVSSs. Under 49 CFR 591.5, the importer would file a declaration under 591.5(c), that the vehicle does not comply with all applicable Federal motor vehicle safety, bumper, and theft prevention standards, but is intended solely for export.

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

John Womack Acting Chief Counsel

TEXT: Dear Mr. Vinson:

Southwest Research Institute (SwRI) has been asked to help determine the desirability of adding a "deceleration" or "pre-braking" warning light to the light configuration which is normally used on automobiles. As presently envisioned, this light woul d be amber in color and would be illuminated when the driver removes pressure from the accelerator pedal sufficiently to cause the automobile speed to start to decrease, due to the effect of engine compression, and would be extinguished automatically whe never the driver reapplies pressure to the accelerator pedal.

SwRI considers that a "deceleration light" of this type has the potential to reduce the incidence of automobile rear-end collisions (see Attachment 1) and that this potential is maximized if the light is located in as conspicuou a location as possible . The "best" location is considered to be immediately adjacent (or as close as possible) to the location of the "high-mounted stoplamp" since this location appears to offer the highest degree of visibility and would also serve to attract attention to th e high-mounted stoplamp area.

This location appears to have already been considered by NHTSA for this purpose, since it is mentioned as a consideration in FMVSS No. 108 on page PRE 137, and the principle is in widespread use on schoolbuses which use a manually activated flashing a mber light to warn that the red stop lights are about to be turned on and that all traffic must stop.

A review of FMVSS No. 108 (Lamps, Reflective Devices, and Associated Equipment) has failed to locate any requirement which would preclude locating an additional light adjacent to the high-mounted stoplamp; however, this type of requirement was conside red at one time (FMVSS 108, pages PRE 132-133 and PRE 135) and SwRI would like to find out if any requirement exists now, or is contemplated for the future, which would prevent the use of this location.

If I can provide further information or answer any questions which might expedite the answer to this question, please call (512) 522-3017.

Sincerely,

DECELERATION LIGHT MAXIMUM BENEFIT SITUATIONS The following three categories of driving situations are considered to be the situations in which deceleration lights would be of maximum benefit in reducing rear-end collisions.

HEAVY TRAFFIC (High speed/high traffic density with decreased vehicle separation distances)

High traffic density, with the associated decrease in visibility and increased need for enhanced reaction time, leads to a situation where reaction times become additive and eventually reach the point where a following driver is placed in a situation where his vehicle has exceeded its physical capability of stopping in time to avoid an accident. Deceleration lights offer the potential for minimizing this progressive lengthening of reaction time and thereby permitting long strings of cars to stop saf ely. Deceleration lights would also provide valuable information about adjoining lane driver intentions, particularly in lane change situations where an apparent opening in an adjoining traffic lane may be about to vanish if the driver of the vehicle at the front of the opening has decided to slow down and has taken his foot off the accelerator preparatory to stepping on the brakes.

MERGING TRAFFIC (Converging situations between vehicles entering or leaving limited access roadways)

A particularly volatile and rapidly changing situation occurs when two streams of traffic merge and the driver of the vehicle with the right-of-way is often forced to guess whether or not a merging driver is going to yield, speed up, or slow down. Th is guess is made harder by the fact that most drivers control their merging maneuver by use of the accelerator pedal only, and thus leave only the rate-of-change of their speed as a clue to their intentions. The driver with the right-of-way is almost al ways driving the faster, overtaking, vehicle and would be able to see a deceleration light which could furnish valuable clues about the other driver's intentions. A deceleration light would also furnish valuable information to drivers following the vehi cle with the righ-of-way if that driver decides to "let up on the gas" and give a merging vehicle more room to complete the merging maneuver.

DECREASED TRACTION (Braking situations where low traction may cause skids or other loss of control situations if brakes are applied too heavily)

Many drivers fail to realize the need for increased spacing between car during slippery conditions (rain, snow, ice, etc.). At the same time most drivers are taught that the proper way to slow down in slippery conditions is to let up on the accelerat or and allow the vehicle to decelerate gradually. This combination is likely to cause accidents involving following cars which do not realize that they are following a car which is slowing down until it is too late for them to make a controlled stop. A deceleration light would provide this information for following drivers and allow them to initiate their own stop, or speed reduction, in time to remain in control.

ATTACHMT: ATTACHED TO 8/21/95 LETTER FROM HUGH J. BODE TO JOHN WOMACK

TEXT: Dear Mr. Bode:

This responds to your letter concerning whether 49 U.S.C. @@ 30101 et seq. (formerly the National Traffic and Motor Vehicle Safety Act) requires a motor vehicle manufacturer to ensure that its vehicle continues to comply with applicable Federal motor vehicle safety standards (FMVSSs) after the first retail purchase of the vehicle.

You specifically ask about FMVSS No. 124, "Accelerator Control Systems," and its application to a 1988 Dodge Ram 50 pickup truck. It appears from the questions you ask that corrosion developed inside the carburetor of the pickup truck at some point during the life of the vehicle, such that the carburetor would not return to idle in accordance with the requirements of Standard No. 124.

You asked us to "confirm the accuracy" of a number of statements. Your first statement, concerning the application of the FMVSSs generally, is as follows:

As we understand it, former @ 108(a) (1) (A) of the National Traffic and Motor Vehicle Safety Act, 49 U.S.C. @ 30112(a), prohibits any person from manufacturing, selling or introducing into commerce any new motor vehicle unless the vehicle is in conformity with all applicable FMVSS. However, the Safety Act further provides that the requirement that a vehicle comply with all applicable FMVSS does not apply after the first purchase for purposes other than resale, i.e., the first retail sale of the vehicle. Safety Act former @ 108 (b) (1), 49 U.S.C. @ 30112 (b) (1).
