NHTSA Interpretation File Search

Overview

NHTSA's Chief Counsel interprets the statutes that the agency administers and the standards and regulations that it issues. Members of the public may submit requests for interpretation, and the Chief Counsel will respond with a letter of interpretation. These interpretation letters look at the particular facts presented in the question and explain the agency’s opinion on how the law applies given those facts. These letters of interpretation are guidance documents. They do not have the force and effect of law and are not meant to bind the public in any way. They are intended only to provide information to the public regarding existing requirements under the law or agency policies. 

Understanding NHTSA’s Online Interpretation Files

NHTSA makes its letters of interpretation available to the public on this webpage. 

An interpretation letter represents the opinion of the Chief Counsel based on the facts of individual cases at the time the letter was written. While these letters may be helpful in determining how the agency might answer a question that another person has if that question is similar to a previously considered question, do not assume that a prior interpretation will necessarily apply to your situation.

  • Your facts may be sufficiently different from those presented in prior interpretations, such that the agency's answer to you might be different from the answer in the prior interpretation letter;
  • Your situation may be completely new to the agency and not addressed in an existing interpretation letter;
  • The agency's safety standards or regulations may have changed since the prior interpretation letter was written so that the agency's prior interpretation no longer applies; or
  • Some combination of the above, or other, factors.

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). 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 unreasonably 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 developed 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 existence 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 - 40 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.

If you have any questions about the information provided above, please contact Dorothy Nakama of my staff at this address or at (202) 366-2992.

TITLE: NONE

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 dispensation 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. The 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 vehicle 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 inoperative" 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 crashes. 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 agency.

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 disconnecting 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 decision.

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" prohibition 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 the 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.

Mr. Byung M. Soh
Marketing Director
Target Marketing Systems, Inc.
P.O. Box 59483
Chicago, IL 60659-0483

Dear Mr. Soh:

This is in reply to your letter of June 20, 1988, with respect to two motor vehicle lighting products which you intend to import into the United States. You have asked "whether these devices require approvals from D.O.T."

First let me explain that the Department of Transportation does not "approve" or "disapprove" specific products. It does advise whether a product appears allowable under the National Traffic and Motor Vehicle Safety Act and the Federal Motor Vehicle Safety Standards.

Your letter does not indicate whether you wish to market these devices as original equipment to be installed before initial sale of a motor vehicle, by either its manufacturer or dealer, or whether you intend to market them solely through the aftermarket. I shall address each situation. The Federal motor vehicle safety standard that applies to original equipment is Standard No. l08 Lamps, Reflective Devices and Associated Equipment. Paragraph S4.1.3 of Standard No. l08 allows additional motor vehicle equipment provided that it does not impair the effectiveness of the lamps and reflectors required as original equipment. Effectiveness may be impaired if the device creates a noncompliance in the existing lighting equipment or confusion with the signal sent by another lamp, or functionally interferes with it, or modifies its candlepower to either below the minima or above the maxima permitted by the standard. In addition, a motor vehicle must remain in conformance with Standard No. l08 (and all other safety standards) until its first purchase for purposes other than resale. There is no Federal standard that applies to your devices as aftermarket equipment, but the National Traffic and Motor Vehicle Safety Act prohibits a manufacturer, distributor, dealer, or motor vehicle repair business from knowingly rendering inoperative, in whole or in part, original lighting equipment.

Your first device is called a "foglight converter." The advertising literature attached states that its function is to turn "the existing headlights...into foglights...." In our opinion, such a device would create a noncompliance with Standard No. l08 by rendering the headlamp function unavailable when the fog lamp converter is in use. We shall assume that the headlamp would be converted into a fog lamp meeting the specifications of SAE Standard J583 MAY8l Front Fog Lamps. None of the photometric test points of SAE J583 coincide with those specified for headlamps. Our further concern with this device is that a driver might fail to return to the headlamp mode from the fog lamp mode, and operate the vehicle with reduced frontal lighting.

The situation differs with respect to the aftermarket. Under the National Traffic and Motor Vehicle Safety Act, a manufacturer, distributor, dealer, or motor vehicle repair business may not perform modifications that render inoperative, in whole or in part, equipment such as headlamps added pursuant to a Federal safety standard. We believe that the installation of the converter could affect the operability of the headlamp within the meaning of the statutory prohibition. However, we note that the foglight converter is advertised as "easy for any driver to attach to any vehicle." As an owner is not a manufacturer, distributor, dealer, or motor vehicle repair business, the owner is not restricted under Federal law from modifications to his vehicle. He is, however, subject to the laws of the States in which his vehicle is registered and operated. We are not conversant with how State lighting laws might affect use of the foglight converter, and you may wish to obtain an opinion from the American Association of Motor Vehicle Administrators, 4600 Wilson Boulevard, Arlington, VA 22203.

We have several other comments as well. The literature you enclosed depicts the foglight converter attached to what appears to be the European-designed H-4 bulb. Standard No. l08 does not permit headlamps with H-4 light sources to be sold for use on 4-wheeled motor vehicles. In addition, the application of the device where motion is translated from the lamp's exterior to the interior by a linkage in the bulb base would affect compliance with the requirement that the bulb base withstand a pressure differential of l0 psi. Additionally, creating a hole or passage for a linkage has the potential of rendering the headlamp noncompliant with Standard No. l08's requirements for certain environmental tests, such as resistance to dust, corrosion, and humidity.

Your second device is a "headlamp intensity modulator," adjusting a headlamp beam "automatically from low to high beam through a middle beam." According to your literature, when a sensor notes the beams of an oncoming car 500 meters ahead the upper beam gradually passes through a middle beam and diminishes into a lower beam when the vehicles are 150 meters apart. This device is also advertised as capable of owner installation, and without the modification of any vehicle parts. The system appears to operate by a switch. This device directly conflicts with Standard No. l08, and its use would create a noncompliance with it. Headlamps are defined as producing upper and lower beams, and means must be provided for switching between these beams. Use of the device would alter upper and lower beam characteristics from those required by Standard No. l08, and in effect create an infinite number of beams while passing from a conforming upper beam at one extreme to a conforming lower beam at the other. This precludes its use as original equipment. We believe that its aftermarket legality would be limited. Although Federal law would not preclude an owner from installing it, the instructions are sufficiently complex that in our opinion many purchasers would seek help from a "dealer" or "motor vehicle repair business," which could not be legally given. There would also remain the question of legality with State laws.

These appear to be innovative devices and we regret that we cannot be more encouraging.

Sincerely,

Erika Z. Jones Chief Counsel

Fort Worth, TX 76117

Dear Ms. Stauffer:

This responds to your letter asking for interpretations regarding the permissibility of modifications which affect compliance with the Federal Motor Vehicle Safety Standards. I apologize for the delay in our response. You tell us that you are a modifier of vehicles for the disabled and sometimes must alter equipment for the use of your customers.

In general, repair businesses are permitted to modify vehicles without obtaining permission from the National Highway Traffic Safety Administration (NHTSA) to do so, but are subject to certain regulatory limits on the type of modifications they may make.

NHTSA is authorized to issue Federal Motor Vehicle Safety Standards that set performance requirements for new motor vehicles and items of motor vehicle equipment. Manufacturers are required to certify that their products conform to our safety standards before they can be offered for sale. If a certified vehicle is modified, other than by the addition, substitution, or removal of readily attachable components, prior to its first retail sale, the person making the modification is an alterer and is required to certify that, as altered, the vehicle continues to conform to all applicable safety standards. After the first retail sale, there is one limit on modifications made to vehicles. Manufacturers, distributors, dealers, and repair businesses are prohibited from "knowingly making inoperative" any device or element of design installed on or in a motor vehicle in compliance with an applicable safety standard. In general, the "make inoperative" prohibition would require a business which modifies motor vehicles to ensure that they do not remove, disconnect, or degrade the performance of safety equipment installed in compliance with an applicable safety standard. Violations of this prohibition are punishable by civil penalties of up to $1,100 per violation.

In situations where a vehicle must be modified to accommodate the needs of an individual with a particular disability, we have, where appropriate, been willing to consider certain unavoidable violations of the "make inoperative" prohibition as purely technical ones justified by public need, and issued a letter to that effect. However, it is often possible to make modifications in a way that does not degrade the performance of safety equipment installed in compliance with an applicable standard.

The situation currently before you concerns relocation of the center highmounted stop lamp (CHMSL), required by Standard No. 108, specifically on the 1997 General Motors G Van, on which you want to "raise the rear doors." As you understand it, "we can relocate the light as long as we reposition it in such a way that it is still visible for its intended purpose." You ask whether we can "clarify that in more detail."

Raising the CHMSL above its original location does not, by itself, create a compliance problem since Standard No. 108 sets no upper limit for the mounting height of CHMSLs. In its new location, however, the CHMSL must not be obscured or tilted; Lift-Aid must ensure that the lamp remains in compliance with the location, visibility, and photometric requirements of Standard No. 108. This means that, as relocated, the lamp(s) must remain on the vertical centerline not less than 34 inches above the road surface, and must not be obscured by any other motor vehicle equipment so that the photometric and visibility requirements of Standard No. 108 continue to be met. If this is insufficiently clear to you, you may FAX a photo of your intended location to us (FAX 202-366-3820)and we will be pleased to advise you further. You may also telephone Taylor Vinson of this Office (202-366-5263).

You also asked about several other situations, identified below, and ask what the "proper documentation" would be.

  1. Removal of air bags from steering wheel at customer's request for the following reasons:
    1. Adding a spinner or driver knob to wheel that may rupture the air bag or that may become a projectile when air bag deploys.
    2. Occasionally we have to add a steering wheel column extension to bring the steering wheel closer than the normal position for persons with limited arm movement.

  2. Removal of the new female side seat belt pretensioner on the new 1997 Ford van in order to install a 6 way driver power seat base that enables a disabled person to transfer into the driver seat.
  3. Occasionally we have to move the rear sofa back to make room for the wheelchair lifts which also affects the seat belts.

If you believe that certain modifications must be made to accommodate the needs of an individual with a particular disability, and that the modifications cannot be made without violating the "make inoperative" provision discussed above, you may write to us and request a letter stating that we will not enforce that provision. The letter should identify the specific facts at issue and why you cannot avoid violating that provision. It should also demonstrate the that proposed modifications minimize the safety consequences of the noncompliances. I note that the modifications you have identified 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.

With respect to removing an air bag because a spinner or driver knob has been added to the wheel, I note that it is not clear that it is desirable to remove an air bag in the situation you describe. I have enclosed for your information a copy of a recent report titled "Air Bag Interaction with and Injury Potential from Common Steering Control Devices."

I hope this information is helpful. If you have any further questions, please feel free to call Edward Glancy of my staff at (202) 366-2992.

Mr. Richard P. Cuvala
Trix Mfg. Co. Inc.
500 W. Irving Pk. Rd.
Bensenville, IL 60106

Dear Mr. Cuvala:

This responds to your letter of September 10, 1995, concerning "conference and display vehicles" you have been asked to manufacture for a client. The vehicles used are cargo vans with a gross vehicle weight rating of 9200 pounds. You convert the cargo area of the van to a product display and conference area. Your letter contained an illustration of the vehicle, indicating an L-shaped seating area behind the driver and front passenger seats. Your letter states that this area is not intended for transport of people. You asked whether such a vehicle must comply with "seating and occupant orientation and restraint directives." As explained below, the seats in such a vehicle would have to comply with federal standards on seats and seat belts if the modification is done prior to the first retail sale of the vehicle.

By way of background information, the National Highway Traffic Safety Administration (NHTSA) is authorized to issue Federal Motor Vehicle Safety Standards that apply to the manufacture and sale of new motor vehicles and new items of motor vehicle equipment. NHTSA does not approve or certify any vehicles or items of equipment. Instead, each manufacturer is required to certify that its motor vehicles comply with all applicable Federal safety standards prior to their sale or import. NHTSA's certification regulations are set forth in 49 CFR Part 567.

Conversion Prior to Sale

Your letter does not state whether the conversion of the cargo area of these vehicles is done before or after the first retail sale of the vehicles. Prior to the first retail sale of a vehicle, the vehicle is considered to be "new." If the conversion is done prior to the first retail sale, your company would be considered an "alterer" under our regulations. A person who alters a previously certified new vehicle also must certify that the altered vehicle complies with all applicable standards (49 CFR '567.7).

The seats in a new vehicle must comply with federal regulations if they are "designated seating positions." A "designated seating position" is defined in 49 CFR 571.3 as:

any plan view location capable of accommodating a person at least as large as a 5th percentile adult female, if the overall seat configuration and design is such that the position is likely to be used as a seating position while the vehicle is in motion.

While you indicate that the vehicles are not intended to transport people except in the front seats, the design of the seating area is similar to other vehicle seats. Therefore, it appears from their design that these seats are likely to be used and are therefore designated seating positions.

NHTSA has exercised its authority to establish five safety standards which could be relevant to seats in these vehicles: Standard No. 207, Seating Systems (49 CFR 571.207), Standard No. 208, Occupant Crash Protection (49 CFR 571.208), Standard No. 209, Seat Belt Assemblies (49 CFR 571.209), Standard No. 210, Seat Belt Assembly Anchorages (49 CFR 571.210), and Standard No. 302, Flammability of Interior Materials (49 CFR 571.302).

Standards Nos. 207, 208, 210, and 302 apply, with certain limited exceptions not relevant to your conversion, to vehicles and not directly to items of equipment. Standard No. 207 establishes requirements for seats, their attachment assemblies, and their installation to minimize the possibility of their failure in a crash. Standard No. 207 does not require a specific orientation for seats. However, some of the requirements are different for side- and rear-facing seats like those illustrated in your attachment.

Standard No. 208 specifies seat belt requirements for seating positions in vehicles. For the seats in the rear of your vehicles, Standard No. 208 would require lap belts at each designated seating position. Standard No. 210 specifies performance requirements for seat belt anchorages. Standard No. 302 specifies burn resistance requirements for materials used in the interior of motor vehicles. Standard No. 302 would affect not only the seats, but also installation of other materials in these vehicles.

Standard No. 209 applies to seat belt assemblies as separate items of motor vehicle equipment, regardless of whether the belts are installed as original equipment in a motor vehicle or sold as replacements. Thus, the manufacturer is required to certify that the seat belts comply with Standard No. 209. If you do not manufacture the seat belts yourself, you should install only belts certified by their manufacturer. This is true regardless of whether the conversion occurs before or after the first sale of the vehicle.

Conversion After Sale

If the conversion is done on a used motor vehicle, you do not have to certify that the vehicle complies with Standards Nos. 207, 208, 210, and 302. However, 49 USC '30122 provides, in pertinent part:

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 vehicle safety standard. . . .

Thus, you could not convert these vehicles if the conversion affected a device or element of design, installed prior to sale, so as to cause the vehicles to no longer comply with any of the safety standards.

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

FROM: AUTHOR UNAVAILABLE; Frank Berndt; NHTSA

TITLE: FMVSS INTERPRETATION

TEXT:

Dear Mr. Rudd:

This responds to your recent letter on behalf of your constituent, Mrs. Jan Wilson, asking whether Federal law restricts motorists from having darkly tinted films installed on the window of their automobiles.

The National Highway Traffic Safety Administration has authority to govern the manufacture of new motor vehicles and motor vehicle equipment. We have promulgated Federal Motor Vehicle Safety Standard No. 205, Glazing Materials, which specifies performance and location requirements for glazing used in vehicles. These requirements include specifications for minimum levels of light transmittance. Seventy percent transmittance is required in all areas requisite for driving visibility, which includes the windshield and all windows in passenger cars. This specification for light transmittance precludes darkly-tinted windows in new automobiles.

The agency has stated in past interpretations that solar films are not glazing materials themselves, and would not have to comply with Standard No. 205. However, use of such films on motor vehicles in certain cases would be prohibited if the vehicle glazing no longer complied with the light transmittance requirements of the standard (most of these films do reduce light transmittance below 70%). If a vehicle manufacturer or dealer places the film on glazing in a vehicle prior to sale of the vehicle, that manufacturer or dealer has to certify that the glazing continues to be in compliance with the requirements of Standard No. 205 (i.e., has to certify that the glazing still has transmittance of at least 70%).

Regarding vehicles that have already been purchased, section 108(a)(2)(A) of the National Traffic and Motor Vehicle Safety Act (15 U.S.C. 1381) provides that no manufacturer, distributor, dealer or motor vehicle repair business shall knowingly render inoperative any device or element of design installed on or in a motor vehicle in compliance with an applicable motor vehicle safety standard. Thus, none of those persons may knowingly install a solar film on a vehicle for its owner if the vehicle glazing would no longer meet the light transmittance requirements of Standard No. 205. Whether this would be the case would have to be determined by the person making the installation. Violation of this provision could subject the manufacturer, distributor, dealer or motor vehicle repair business th civil penalties up to $1,000 for each violation.

Please note, however, that under Federal law the vehicle owner may alter his or her vehicle as is desired. This agency does not govern use of vehicles by owners; this is left to the States. Thus, under Federal law, an owner could install solar film on his or her vehcile whether or not such installation affected compliance with Standard No. 205.

In summary, Federal law does not preclude Mrs. Wilson from having darkly tinted film on her passenger car, provided she installed the film herself. However, if a manufacturer, dealer, distributor or motor vehicle repair business (including an auto tint shop) installed the film for Mrs. Wilson, they are in violation of Federal law if the glazing no longer meets the 70% light transmittance requirements of Standard No. 205. The State of California is, of course, free to prohibit vehicle owners from operating vehicles with darkly tinted glazing in its jurisdiction.

DATE DETAILS

1/3/83 Mrs. Wilson is the daughter of Saxton Pettit whom she says was a very good friend of the Congressman. He used to own the Basket House in Scottsdale. Mrs. W. said the Basket House was America's largest basket store. Her father is now deceased. Mrs. Wilson would like the Congressman' help in acquiring a special pass to enable her to drive from Arizona to California with tinted windows on her car. Apparently Mrs. W. goes through an extension of UCLA for medical treatment. She was stopped on the highway and given a citation for driving in California with tinted windows as the law in California is such that you cannot drive with tinted windows if they don't comply with the designated degree of tint. The ticket amount is $75. She said she called the courthouse in California and explained her situation and asked for a special pass to drive in California. She doesn't think she should have to take off the tint just to drive in California. She said she was told that she could remove the tint, but still have to pay the citation or she would have to drive with her windows rolled down while in California. She thinks these answers are absurd and she doesn't think it fair that she was slapped with such a high fine without even getting a warning first. She said the highway patrolman told her he was just doing his job. She tried to explain that she was unaware of the law and that she only travels to California for treatment. Mrs. W. also said her lawyer tried to talk to the courthouse, but to no avail. I explained to Mrs. W. that this is a state law of California and that there is nothing the Congressman can do as he handled matters on the federal level. I said she would have to comply with our laws. She then said that the highway patrolman told her that this is a federal law. I said I didn't think so, but would forward this to our W.O. for verification. I also suggested she write the Cong. a letter asking him to contact the State of California as it is policy to have a request such as that in writing. She said she is a very sick woman, and doesn't want to take the time and effort if she doesn't have a valid case.

Ms. Susan Reilly Reilly Manufacturing P.O. Box 51 Mt. Vernon, Iowa 52314

Dear Ms. Reilly:

This responds to your letter asking whether a motorcycle helmet fastener your company produces, called "Alpha Clip," complies with Federal requirements.

By way of background information, this agency does not give approvals of vehicles or equipment. The National Traffic and Motor Vehicle Safety Act places the responsibility on the manufacturer to ensure that its vehicles or equipment comply with applicable standards.

Safety Standard No. 218, Motorcycle Helmets, includes various minimum performance requirements for motorcycle helmets. The only requirement directly relevant to your fastener is the retention test, which is set forth at section S5.3. The letter you enclosed from the University of Southern California suggests that the clip passes that test.

I would note that Standard No. 218 only applies to new motorcycle helmets and not to replacement equipment for motorcycle helmets. Thus, unless your clip was sold as part of a new motorcycle helmet, the requirements of Standard No. 218 would not be directly applicable. (Please note, however, that the agency discourages helmet users from modifying their helmets. Section S5.6.1 of the standard requires that the following instruction be placed on helmets: "Make no modifications..")

I would also note that should a safety-related defect be discovered in your device, whether by the agency or by yourself, you as the manufacturer would be required under sections 151 et seq. of the Act to notify owners, purchasers, and dealers and provide a remedy for the defect. These provisions apply regardless of whether the device is covered by a safety standard. A copy of the Act is enclosed.

Dear Mr. Berndt:

At the advice of Mr. Gilky of the NHTSA Safety Compliance Office I am writing for your judgement as to the compliance of our Motorcycle Helmet Fastener to Federal requirements. We believe the "Alpha Clip" meets all requirements and is a safe and reliable product. I have included the clip, packaged for mail order, for your review. As of now, we market only the clip, not O-rings or helmets, and the consumer is responsible for installation.

I have also included a copy of a (unreadable) of U.S.C.. He then tested our fastener as a public service. Since receiving his letter we've added a plastic vinyl cap fitted to the hook, creating an interference fit.

Other recent information is as follows: 1 The hook is designed to fold in within itself when tension is released (we are in the process of moving the design patented)

2. Made of nickel plated (unreadable) steelwire of .142 +.005 - .000 inches dia. Length .900 I .020 in., width l.l90 I .020 in., width .702 I .010 Weight .

3. Has a deformation point of 600 pounds tensile

4. Does not protrude from the helmet

5. Installs directly to helmet strap - nothing is removed from the helmet.

I have also sent a clip and information to Mr. B. Roven, Coordinator of Motorcycle Safety for the Iowa DOT, if you wish to contact him for comment. Please let us know your judgement on our clips compliance as soon as possible.

Thank you for your time and cooperation.

Sincerely, Susan Reilly

Mr. Steve Reilly RR 2 Mount Vernon, IA 52314

Dear Steve,

Thank you for sending your new retention clip to us for evaluation. Professor Hurt asked me to run some tests on it and give you some comments.

The beauty of your clip design is that it could be retrofitted to most helmets providing a much more convenient method of fastening than conventional D-rings.

The first test I did was to use your clip on a complete helmet for the actual DOT retention test. Enclosed is that portion of the standard. I used an Electro E3 which has an extremely strong retention system. This choice of helmets made your part the weak link. With the Reilly clip in place, the test result was 0.54 inch elongation @ 300 lbs., about normal for an Electro. The clip showed no deformation at this load.

Taking the entire system up in loading, the strap began to slip at 640 lbs. when the unwelded ends of the clip deformed. This load at failure is typical for many helmets that pass the DOT requirements.

The problem that your design has is answered by many industrial safety codes that require a safety snap latch on all hooks. This spring-loaded device swings inward when engaging the hook and then returns to block the throat of the hook creating a closed loop. Bell Tourlite bicycle helmets use a somewhat similar hook with a safety latch made by Fastex. A less satisfactory solution would be to close up the radius of the hook bend to create an interference fit onto the D-ring.

Please feel free to send out any future revisions to us for evaluation. As with the better mousetrap, the world is ready for a better helmet retention strap fastener.

TITLE: FMVSS INTERPRETATION

TEXT:

Dear Mr. Dorgan:

This responds to your letter to Secretary Dole, raising concerns expressed to you in a letter signed by Mssrs., Rick Herbel and Douglas Glove, two of your constituents. These gentlemen asked why school districts are not permitted to purchase vans which do not satisfy the comprehensive school bus safety standards, when such vans would "be used only for hauling cheerleaders, supplies and etc." These gentlemen noted that the capacity of these vans would be from 10 to 15 people, and that they would be more economical to use than a full-size school bus. As is more fully explained below, the answer is that the National Traffic and Motor Vehicle Safety Act, as amended (hereinafter referred to as "the Act"), together with the comprehensive safety standards for school buses (which the Act required this agency to issue) require that all vehicles designed to carry more than 10 persons which are significantly used to transport school students must be certified as meeting those safety standards. Ordinary passenger vans are not certified as doing such, and therefore cannot be so used.

In 1974, Congress passed the School Bus and Motor Vehicle Safety Amendments (Pub. L. 93-492; hereinafter referred to as "the Amendments"). The Amendments added to the Act the following definition of a school bus; "a passenger motor vehicle which is designed to carry more than 10 passengers in addition to the driver, and which...is likely to be significantly used for the purpose of transporting primary, preprimary, or secondary school students to or from such schools or events related to such schools; ..."(15 U.S.C. 1391(14)). Those Amendments also provided that, not later than 15 months after they were enacted, the National Highway Traffic Safety Administration had to promulgate minimum performance standards for specified aspects of safety performance. The Amendments specified further that these standards "shall apply to each school bus and item of school bus equipment which is manufactured in or imported into the United States on or after April 1, 1977." (15 U.S.C. 1392(i)(1)(B)).

Prior to this Congressional action, many school districts had used so-called "activity buses" to transport students to and from extra-curricular activities. The activity buses were used because they were said to be more comfortable, more prestigious, and so forth. The floor debates on the Amendments show that Congress was aware of the practice of using these activity buses, yet chose to specify a broad definition of school bus. Congress took this step to require vehicles used solely for extracurricular activities to meet the same safety standards as those used to transport the children to and from school. This decision was based partly on the fact that 150 children were killed in 1971 in school bus accidents (see 120 Cong. Rec. H8120, daily ed., August 12, 1974). The statistics since the Amendments were passed indicate that Congress' goal of greatly reducing these facilities has been accomplished by the school bus safety standards promulgated by this agency. In 1981, the last year for which complete statistics are available, there were 10 fatalities in school bus accidents.

There are two courses of action open to your constituents if they wish to purchase vans for extracurricular activities. First, they could purchase a smaller 9-passenger van, because these vehicles would not be considered school buses under the Congressional definition, which applies only to vehicles carrying more than 10 passengers. Second, they can purchase 15 passenger vans which have been modified and certified as complying with the school bus safety standards. A number of companies will make the necessary modifications to these vans so that they can be certified as complying with those standards.

If you have any further questions on this subject or need any further information, please do not hesitate to contact me.

Oct. 24, 1983

Representative Byran Dorgan Washington, DC

Dear Representative Dorgan,

We have a question on Federal Regulations on why School Districts can not purchase a van type vehicle from a local dealer without meeting full bus specifications when the van would be used only for hauling cheerleaders, supplies and etc. The capacity is from 10 to 15 people and this includes the driver. This is more economical for a school to be able to handle a small group of people say 5 or 6 than to have to use a bus which gets poor mileage and cost considerably more to drive. Can the school purchase a van for small groups and hauling supplies and is this permissible in the regulation?

Thank you,

    Terex-Demag GmbH & Co. KG
    Dinglerstr. 24
    D-66482 Zweibrcken
    GERMANY


    Dear Mr. Molinari:

    This responds to your request for an interpretation concerning whether Terex-Demag products that your company imports into the United States are "motor vehicles". You asked four questions, which are addressed below.

    You specifically asked that we address whether the Terex-Demag AC 80-2 All Terrain Mobile Crane is a "motor vehicle". You have enclosed brochures (with photographs and diagrams) describing the AC 80-2, as well as brochures for a number of other products.

    By way of background information, the National Highway Traffic Safety Administration (NHTSA) administers the laws under which the Federal motor vehicle safety standards (FMVSSs) are promulgated.

    You first question was whether the Terex-Demag AC 80-2 All Terrain Mobile Crane is considered a "motor vehicle". In response, we note that NHTSAs statute at 49 U.S.C. Section 30102(a)(6) defines the term "motor vehicle" as follows:

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

    We have issued a number of interpretations of "motor vehicle". We have stated that vehicles equipped with tracks, agricultural equipment, and other vehicles incapable of highway travel are not motor vehicles. We have also determined that certain vehicles designed and sold solely for off-road use (e.g. , airport runway vehicles and underground mining vehicles) are not motor vehicles, even if they may be operationally capable of highway travel. Finally, we have concluded that items of mobile construction equipment that use the highways only to move between job sites and that typically spend extended periods of time at a single site are not motor vehicles. However, we do consider vehicles that use the public roads on a necessary and recurring basis to be motor vehicles. If a vehicle is a "motor vehicle," it must comply with all applicable FMVSSs in order to be imported into the United States (49 U.S.C. 30112(a)).

    Based on the brochure provided with your letter, we believe the Terex-Demag AC 80-2 All Terrain Mobile Crane is substantially similar to the mobile cranes that were the subject of our interpretation letters of March 11, 1999, to Mr. Chun Jo and of October 20, 2003, to Mr. Michael E. Ogle. As in the cases of the products at issue in these letters, for the Terex-Demag AC 80-2 All Terrain Mobile Crane, the use of the highway appears to be merely incidental and not the primary purpose for which it was manufactured. Therefore, we do not consider the Terex-Demag AC 80-2 to be a "motor vehicle".

    I note that while you indicated in your letter that you were particularly concerned about the AC 80-2, you enclosed literature about other products. For the same reasons discussed in the previous paragraph, it is our opinion that the other cranes for which you provided individual brochures, specifically, the AC 500-2, AC 250-1, AC 140, AC 200-1, AC 55, AC 40 City, and AC 30 City are not considered to be "motor vehicles".

    Your second question was whether, if the Terex-Demag products are not motor vehicles, they can legally operate on the highway or any other road without "DOT stamps". I note that you stated in your letter that you are having difficulty obtaining 20.5" tires that have the DOT stamp on them. I will therefore assume that you are asking whether your products may legally operate on the highway if they have tires that are not marked "DOT". The marking of "DOT" on a tire constitutes certification by the manufacturer that the tire meets applicable FMVSSs. If a vehicle is not a motor vehicle, our regulations would not apply to the vehicle, and it would not be required to have tires that met the FMVSSs. The vehicle could, however, be subject to state regulations.

    Your third question concerned our October 20, 2003, letter to Mr. Ogle. You ask if there has been a change in the legal position taken in our interpretation letter to Mr. Ogle.

    As you are aware, we noted to Mr. Ogle that our interpretations on mobile construction equipment are based on a court decision issued in 1978. We further stated:

    Subsequent legal developments make the holding of that court decision open for reassessment. Moreover, some mobile construction equipment may be using the public roads with greater frequency than the equipment the court decided were not motor vehicles subject to our jurisdiction. At some point in the future, we may revisit the issue of whether certain mobile construction equipment should be considered motor vehicles. However, if we were to take such action, we would announce it publicly, and address such issues as what standards should apply to the vehicles and what effective date is appropriate.

    As of this writing, we have not revisited the issue of whether mobile construction equipment such as that manufactured by Terex-Demag should be considered motor vehicles. Thus, the October 20, 2003 interpretation letter to Mr. Ogle remains unchanged.

    Your fourth question is whether there are State laws that "could also warrant the need for DOT stamps on tires of non-motor vehicles". I will assume that in this question, you ask whether there are State laws that require non-motor vehicles to have tires that are certified as meeting NHTSA FMVSSs for tires. You would need to consult the State laws of each of the fifty states to determine the answer to this question.

    The enclosed letter of August 16, 2004, to Kelly A. Freeman, Esq. provides additional guidance in determining when products used in construction may be "motor vehicles".

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

William E. Otto, Esq.

Sebring & Associates

2735 Mosside Boulevard

Monroeville, PA 15146

Dear Mr. Otto:

This responds to your letter asking two questions about the requirements of Federal Motor Vehicle Safety Standard (FMVSS) No. 111, Rearview Mirrors, regarding outside rearview mirrors.

By way of background, the National Highway Traffic Safety Administration (NHTSA) is authorized to issue FMVSSs that set performance requirements for new motor vehicles and items of motor vehicle equipment (see 49 U.S.C. Chapter 301). NHTSA also investigates safety-related defects. The agency does not provide approvals of motor vehicles or motor vehicle equipment.  Instead, manufacturers are required to self-certify that their products conform to all applicable safety standards that are in effect on the date of manufacture. NHTSA selects a sampling of new vehicles and equipment each year to determine their compliance with applicable FMVSSs.  If our testing or examination reveals an apparent noncompliance, we may require the manufacturer to remedy the noncompliance, and may initiate an enforcement proceeding if necessary to ensure that the manufacturer takes appropriate action.

In your letter, you ask about an outside drivers side rearview mirror that would contain two parts. You state that on the right portion of the mirror, a section of the mirror would contain a FMVSS No. 111-compliant flat mirror, while the left portion of the mirror would contain a curved or aspheric component. You also suggested that this additional section may cause the mirror to extend farther than the widest part of the vehicle body. You ask two questions relating to this design, which are restated below.

Q1. You ask whether a single drivers side mirror containing both a flat portion and curved or aspherical portion located to the left of said flat portion would be permitted by S5.2.1 of Standard No. 111, provided that the flat portion of the mirror otherwise complies with Section S5.2.1.

Our answer is yes. FMVSS No. 111, S5.2.1, Field of view, states that [e]ach passenger car shall have an outside mirror of unit magnification, which requires a flat mirror. However, if this requirement is met, there is no specific prohibition on additional mirrored surfaces, which can be convex or aspheric.

In a previous letter of interpretation from 1995, NHTSA answered a similar question in the affirmative. In that letter, we stated, [v]ehicle manufacturers may install mirror systems that combine a portion of the mirror with a straight angle with a portion of the mirror that is at a slight variance, provided that the straight mirror portion by itself complies with the requirements in FMVSS No. 111 that are applicable to the vehicle on which the mirror system is installed.[1] Similarly, in a 1998 letter, NHTSA stated that [v]ehicle manufacturers may install mirror systems that combine flat and convex mirrors on their new vehicles, provided that the flat mirror portion by itself meets FMVSS No. 111 requirements applicable to the vehicle on which the mirror system is installed.[2]

Therefore, assuming your drivers side flat mirror meets the field of view requirements, we can confirm that an additional aspheric portion would not be prohibited.

Q2. You ask whether a drivers side mirror which protrudes farther than the widest part of the vehicle body is permitted under S5.2.2 of FMVSS No. 111, if the extent of the protrusion is limited to the minimum necessary to accommodate a mirror which exceeds the requirements of Section S5.2.1 by the following characteristics: (1) the flat portion of the mirror complies with the requirements of Section S5.2.1 and (b) a curved or aspheric portion of the mirror located to the left of the flat portion of the mirror results in an increase in the field of view.

Assuming that the aspheric portion of your mirror produces a field of view that exceeds S5.2.1, our answer is yes. Paragraph S5.2.2 reads, in part, neither the mirror nor the mounting shall protrude farther than the widest part of the vehicle body except to the extent necessary to produce a field of view meeting or exceeding the requirements of S5.2.1. (Emphasis added.) S5.2.2 as originally adopted (then S3.2.1.2) specified that neither the mirror nor the mounting shall protrude farther than the widest part of the vehicle body, except to the extent necessary to meet the requirements of the field view requirements (32 FR 2408, 2413). Shortly thereafter, the exception was expanded to include the words meeting or exceeding in an early amendment to the standard (32 FR 5498, April 4, 1967, copy enclosed). Since the exception was revised to accommodate mirrors and mountings that produce a field of view exceeding the requirements of S5.2.1, we believe a protrusion to accommodate that part of the mirror is permitted. However, this exception does not extend to protrusions beyond the widest part of the body to accommodate items such as decorations or lights near that part of the mirror. Moreover, the mirror and mounting must be free of sharp points or edges that could contribute to pedestrian injury, as specified elsewhere in S5.2.2.



I hope this answers your questions. If you have any further questions, please contact Ari Scott of my staff at (202) 366-2992.

Anthony M. Cooke
