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.

ID: 2638yOpen Mr. William Waltz Dear Mr. Waltz: This is in reply to your letter of April 12, l990, stating that Wagner Division "would like to petition N.H.T.S.A. for a 'Determination of Inconsequentiality' for non-compliance." Specifically, Wagner wishes to manufacture round sealed beam headlamps (not "bulbs" as you call it) for Lectric Limited, a small parts business geared towards the antique automobile hobby. The headlamps are intended for use on "antique automobiles". We understand that term to mean any automobile manufactured in l940 and subsequent model years that was originally equipped with round sealed beam headlamps. Although the headlamps would be designed to conform to current specifications, those of SAE Standard J579c, the word "top" would be used on the 7-inch diameter headlamp instead of the designation "2CI" (you mean "2D1"), the numeral "1" for "1C1" on the single beam 5 3/4-inch diameter headlamp, and the numeral "2" for "2C1" on the dual beam 5 3/4-inch diameter headlamp. The lamps would not bear "DOT" identification. Lectric Limited is willing to "ink stamp" DOT, 2Dl, 1C1, and 2C1 "on either the face and or the rear" of each headlamp so that they would not be mistaken for those conforming to SAE J579a, and to print instructions for purchasers explaining the difference. Lectric Limited is also willing to insure that the headlamps are marketed only through antique auto specialty retailers. First, let me explain that your request cannot be considered as one for a determination of inconsequentiality. These determinations are made after-the-fact in order to determine whether a manufacturer must fulfill statutory obligations which include replacement, repurchase, or repair of the already-manufactured noncompliant product. What you seek is permission to produce motor vehicle equipment that fails to comply with labeling requirements. Unfortunately, the agency has no exemption provisions which can address this issue. We have authority to exempt manufacturers of motor vehicles from compliance for a temporary period, but we have no authority to exempt manufacturers of motor vehicle equipment, on either a temporary or permanent basis. Further, we cannot waive the marking requirements of sections S7.2 and S7.3 of Standard No. l08, even for the limited purpose and subject to the restrictions you discuss. After due consideration of the matter, we believe that you have no choice other than to conform to the marking requirements of Standard No. l08. Although neither the marking nor the performance of J579c headlamps replicates that of J579a headlamps, I hope that auto enthusiasts will be willing to accept the marking that goes with the improved performance. Sincerely,

ID: 2639oOpen Art Look, Marketing Executive Dear Mr. Look: Your letter of October 30, 1987, addressed to Administrator Diane Steed, was referred to me for reply. You are apparently seeking this Department's approval of your product which you describe as a new warning device for stopped motor vehicles. As explained below, we do not provide approvals for products. Your product is made of inflatable plastic material that you describe as "flexible and extremely durable." When a user inflates your device, the product takes the shape of a cone standing about 18" high. The pictures you enclose indicate that the inflatable part of the cone has three broad alternating stripes. Two of the stripes are orange, and a 6" "reflective" white stripe is sandwiched between them. Your cone sits on a non-inflatable, spherical, black base filled with "approximately" 3 lbs. of sand. You state that your device has many advantages over the warning device currently specified in Federal Motor Vehicle Safety Standard 125, Warning Devices. Among the advantages you list are that your device is "more visible at night, up to 1,000 ft. away;" that it "(is) not affected by winds up to 50 MPH;" and that if struck, it "will return to an upright position" without damaging the vehicle involved. You state your company's intention to package your device in a corrugated container with three inflatable cones to a kit, including both a "new-type double-action hand pump" and instructions for proper use of your device. Let me begin with some general information about this agency. The National Highway Traffic Safety Administration (NHTSA) is an agency of the Department of Transportation, and has authority under the National Traffic and Motor Vehicle Safety Act (the Safety Act) to issue safety standards applicable to new motor vehicles and certain items of motor vehicle equipment. However, NHTSA does not approve nor certify motor vehicles or motor vehicle equipment, or endorse any commercial product. Instead, the Safety Act establishes a "self-certification" process under which each manufacturer is required to certify that its products meet all applicable safety standards issued by this agency. Periodically, NHTSA conducts tests to determine whether vehicles or equipment comply with these standards, and may investigate alleged safety-related product defects. One of the safety standards issued by this agency is Standard 125, Warning Devices, which sets uniform performance requirements for certain devices that are designed to be carried in a motor vehicle and used when needed to warn approaching traffic when the vehicle is disabled and stopped in or by the side of the road. The Standard applies to any such device that does not have a self-contained energy source (such as a battery). Your product falls under this Standard. Thus, it must meet the requirements of Standard 125, such as those on configuration, color, and reflectivity. Failure to comply with a standard renders the manufacturer subject to a civil penalty of $1,000 for each violation and a maximum penalty of $800,000 for a series of violations. In addition, the Safety Act requires a manufacturer to recall and remedy or replace a noncomplying item of motor vehicle equipment. As the above discussion suggests, you do not need approval from NHTSA or any other agency in the Department of Transportation to market your product. However, you do need both to ensure that your product meets Standard 125's requirements and to certify compliance. Our preliminary review of your product indicates that you may not be able to make that certification. For example, it appears that your product may not comply with the color, reflectivity, configuration, and stability requirements of Standard 125. If your product fails to meet these or other Standard 125 requirements, you cannot legally market it as a warning device. I hope you find this response helpful. Sincerely,

ID: 2639yOpen AIR MAIL Mr. Wayne Brush Director, Material Management Conceptor Industries, Inc. 521 Newpark Blvd. P. O. Box 149 Newmarket, Ontario Canada L3Y 4X7 Dear Mr. Brush: Thank you for your letter to Mr. Clive Van Orden of our Office of Vehicle Safety Compliance seeking an interpretation of this agency's requirements for a vehicle identification number (VIN), as set forth in 49 CFR Part 565, Vehicle Identification Number - Content Requirements, and Standard No. 115, Vehicle Identification Number - Basic Requirements (49 CFR 571.115). You stated that your company plans to modify vans manufactured by General Motors (GM) to produce electric powered vehicles for sale in the United States. You asked whether these vehicles may use the GM world manufacturer identifier (WMI), as well as a check digit, model year identification, and production sequence codes assigned by GM, and use an X as the engine type code to show that the vehicles were actually manufactured by your company. As explained below, the answer to your question is no. S4.1 of Standard No. 115 reads as follows: Each vehicle manufactured in one stage shall have a VIN that is assigned by the manufacturer. Each vehicle manufactured in more than one stage shall have a VIN assigned by the incomplete vehicle manufacturer. Vehicle alterers, as specified in 49 CFR 567.7, shall utilize the VIN assigned by the original manufacturer of the vehicle. As described in your letter, Conceptor Industries plans to produce completed electric powered vehicles by using an assemblage of motor vehicle equipment produced by GM, including frame and chassis structure, steering, suspension, and braking systems. However, the assemblage provided to your company by GM would not include a power train. The absence of a power train means that this assemblage would not be an "incomplete vehicle," as that term is defined in S3 of Standard No. 115, so the Conceptor electric vehicles would not be considered to be manufactured in more than one stage. Your company would not qualify as a vehicle alterer, based on the information provided in your letter, because GM would not have already certified the vehicles modified by your company. Thus, the electric powered vehicles produced by Conceptor would be considered to be vehicles manufactured in one stage, and the VIN for these vehicles would have to be assigned by Conceptor, the manufacturer of these vehicles. Part 565 specifies the format and content of the VIN that Standard No. 115 requires your company to assign to its electric powered vehicles. In relevant part, 49 CFR 565.4 provides that: The VIN shall consist of four sections of characters which shall be grouped accordingly: (a) The first section shall consist of three characters which occupy positions one through three (1-3) in the VIN, This section shall uniquely identify the manufacturer, make and type of the motor vehicle if its manufacturer produces 500 or more motor vehicles of its type annually. If the manufacturer produces less than 500 motor vehicles of its type annually, those three characters, along with the third, fourth, and fifth characters of the fourth section shall uniquely identify the manufacturer, make and type of the motor vehicle. * * * Under the approach suggested in your letter, GM would be identified as the manufacturer of the vehicle by the first three characters of the VIN, and the eighth character would indicate that Conceptor was the actual manufacturer. This approach would be plainly inconsistent with the requirements of 565.4 quoted above, because the regulation requires the first three characters in the VIN to identify the vehicle manufacturer. Your company is the manufacturer of these vehicles, not GM, so your company must be identified by the first three characters of the VIN. Furthermore, 565.4(b) provides that the eighth character in the VIN shall uniquely identify specified attributes of the vehicle, not identify the manufacturer. Hence, the approach suggested in your letter would not comply with this agency's VIN requirements. Additionally, you informed Dorothy Nakama of my staff in a July 3, 1990 telelphone conversation that, at least in the initial years of your company's production of these vehicles, the annual production will be less than 500. If this is the case, you should note that 565.4(a) requires your company to use not only the first three characters of the VIN to uniquely identify the manufacturer, make and type of the motor vehicle, but also the 12th, 13th, and 14th characters of the VIN as well to make this unique identification. I hope this information is helpful. If you have any further questions or need any additional information, please feel free to contact Dorothy Nakama of my staff at this address or by telephone at (202) 366-2992. Sincerely,

ID: 2640oOpen Mr. Toshio Maeda Dear Mr. Maeda: This is in reply to your letter of June 30, 1987, asking for an interpretation of paragraph S4.1.1.36(b)(3) of Motor Vehicle Safety Standard No. l08. That paragraph specifies in pertinent part that a replaceable bulb headlamp shall be designed to conform to Section 6.1-Aiming Adjustment Test, of SAE Standard J580 AUG79 Sealed Beam Headlamp Assembly. Section 6.1.1 states that "when the headlamp assembly is tested in the laboratory, a minimum aiming adjustment of +/-4 deg. shall be provided in both the vertical and horizontal planes." You have asked whether the aiming adjustment is to be achieved by the headlamp assembly, or by both the headlamp assembly "and by the headlamp when it is mounted on the vehicle." SAE J580 applies to the design of headlamp assemblies, including the functional parts other than the headlamps, such as aiming and mounting mechanisms and hardware. The assembly may include one or more headlamps. Although the headlamp assembly is tested in the laboratory, its design must be identical to the headlamp assembly used on the vehicle. Thus, if the aiming adjustment requirement is met by the headlamp assembly in the laboratory, it should also be met when the assembly is installed on the vehicle. An individual headlamp installed on the vehicle need not meet the aiming adjustment test unless that headlamp is part of a headlamp assembly comprising only one headlamp. I hope that this answers your question. Sincerely,

ID: 2640yOpen Mr. Ron Boucher Dear Mr. Boucher: Thank you for your letter asking whether the products you plan to market would comply with the laws and regulations administered by this agency. As explained below, the laws and regulations administered by this agency would not be applicable to these products. Enclosed with your letter were two brochures describing the "Signal Flash" personal identification lights. The brochure included pictures and descriptions of several different types of battery-powered lights that are small enough to be carried on one's person, and include straps that make them suitable to be carried on one's arm, around one's wrist, or inserted into a life preserver. The brochures describe these "Signal Flash" lights as suitable for use in "diving, mountaineering, jogging, sailing, windsurfing, cycling, fishing, car breakdown, life jacket, etc." The National Traffic and Motor Vehicle Safety Act (the Safety Act) authorizes this agency to regulate "motor vehicles" and items of "motor vehicle equipment." Section 102(4) of the Safety Act (15 U.S.C. 1391(4)) defines "motor vehicle equipment", in part, as: any system, part, or component of a motor vehicle as originally manufactured or any similar part or component manufactured or sold for replacement or improvement of such system, part, or component or as any accessory, or addition to the motor vehicle... Your "Signal Flash" lights are plainly not a "system, part, or component of a motor vehicle as originally manufactured," nor are they a "similar part or component manufactured or sold for replacement or improvement" of an original equipment part of a motor vehicle. The issue is whether these lights would be considered an "accessory" within the meaning of the Safety Act. In determining whether an item of equipment is considered an "accessory," the agency applies the relevant statutory language and the two following criteria: first, whether a substantial portion of the expected uses of the item are related to the operation or maintenance of motor vehicles, and second, whether the item is intended to be used principally by ordinary users of motor vehicles. In evaluating the first criterion, the product literature enclosed with your letter emphasizes the versatility of these personal identification lights. While these lights occasionally may be used in connection with a motor vehicle breakdown or repair, most of the suggested uses involve sports activities that have nothing to do with a motor vehicle. Thus, a substantial portion of the expected uses of the light would not appear related to the operation or maintenance of a vehicle, so these "Signal Flash" lights would not be considered items of "motor vehicle equipment." This conclusion means that the "Signal Flash" lights are not subject to any of the laws and regulations administered by this agency. You may wish to consult the U.S. Consumer Product Safety Commission to learn if they have any requirements applicable to these lights. That agency protects the public against unreasonable risks of injury from consumer products. You may write to the Consumer Product Safety Commission at 5401 Westbard Avenue, Bethesda, MD 20207, or contact them by telephone at (301) 492-6580. I hope this information is helpful. If you have any further questions or need any additional information, please feel free to contact Dorothy Nakama of my staff at this address or by telephone at (202) 366-2992. Sincerely,

ID: 2643oOpen Mr. Billy S. Peterson Dear Mr. Peterson: This is in reply to your letter of September 23, 1987, with respect to positioning of rear mounted lamps and reflectors in accordance with Federal Motor Vehicle Safety Standard No. l08. Your client has designed a vehicle in which the backup lamps and rear reflex reflectors would be mounted on the deck lid, and you have asked whether there are any current or contemplated prohibitions that would preclude this design. The lamps in question will be mounted on a rigid part of the vehicle as required by paragraph S4.3.1 of Standard No. l08, and the deck lid will be closed and the lamps and reflectors in full view under normal operating conditions. The visibility requirements of lamps and reflectors in Standard No. l08 are predicated on the normal driving or closed deck lid position. Since the use of motor vehicles, including driving with deck lids open or otherwise having the lamps and reflectors obscured by a particular load on the vehicle is under the jurisdiction of the individual States, we do not anticipate rulemaking on this subject. Thus this design is not prohibited by Standard No. l08. Sincerely,

ID: 2644oOpen C.D. Black, Engineering Manager Dear Ms. Black: This is in reply to your letters of June 8 and October l7, 1987, with respect to an electrically-operated headlamp leveling system that Jaguar intends to offer on passenger cars beginning with the l989 model year. Such a device is required by EEC regulations. You have informed us that the system does not allow lamps to be adjusted above the "zero" position, only downward to compensate for rear end loading of the vehicle. There is no provision for automatic return to the "zero" position when the engine is turned off. Further, there will be no indication to the driver from the vehicle instrumentation that re-aim is necessary when the headlamps are adjusted downward. You have concluded, for the six reasons given in your letter of June 8 that "no aspect of FMVSS l08 . . . is contravened by this proposed installation." The sole restriction that Standard No. l08 imposes upon an item of motor vehicle equipment not covered by the standard but which a manufacturer wishes to add to a vehicle as original equipment is that it not impair the effectiveness of the lighting equipment that the standard requires (S4.l.3). If a manufacturer concludes that the unrequired equipment would not impair the effectiveness of the required lighting equipment, it may certify that the vehicle complies with Standard No. 108. Based on our understanding of your system, it does not appear to impair the effectiveness of the required equipment. However, we urge you to consider the possible consequences if the driver forgets to return the system to the "zero" position from either of the two adjustment positions. These possibilities are a concern because the system does not automatically return to that position, and no warning is provided to the driver that the headlamps are not in their original design position. On the other hand, if properly used, the system could enhance headlighting effectiveness by ensuring that the headlamp provides the same lighting performance under all conditions of vehicle load. We hope the information is helpful. Sincerely,

ID: 2645oOpen Mr. Edgar G. Meyer Dear Mr. Meyer: This responds to your November 24, l987 letter asking about the applicability of Federal Motor Vehicle Safety Standard No. 302, Flammability of Interior Materials, to the manufacture of automobile seat cushions and seat backs. Specifically, you asked whether it would be permissible if the fabric (i.e., felt) from which the seat cushions and seat backs would be manufactured were made from "old clothes and rags." Standard No. 302 neither specifies nor prohibits any particular type of raw material used to manufacture seat backs and seat cushions. The felt must meet the flammability requirements of the standard if it is used for cushions and seat backs for new motor vehicles. Also, felt used to manufacture seat cushions and seat backs for new and used motor vehicles must contain no safety related defects. The National Traffic and Motor Vehicle Safety Act and NHTSA regulations require manufacturers of new motor vehicles to certify that their vehicles comply with all applicable Federal motor vehicle safety standards, including Standard No. 302. Standard No. 302 specifies burn resistance requirements for materials used to manufacture seat cushions and seat backs on new passenger cars, multipurpose passenger vehicles, trucks and buses. Thus, any person manufacturing a new vehicle with seat backs and seat cushions made from the felt material you described must ensure that the seat backs and cushions possess the burn resistance characteristics required by Standard No. 302. If the felt can meet those requirements, it may be used in new motor vehicles in satisfaction of Standard No. 302, regardless of the felt's raw materials. The felt manufacturer should also be aware that the Vehicle Safety Act requires all vehicle and equipment manufacturers to ensure that their products contain no defects relating to motor vehicle safety. If it were determined by the manufacturer or this agency that the seat cushions and seat backs had a safety related defect, all purchasers of the vehicle containing the defective equipment would have to be notified and the defective item repaired or replaced without charge. If the felt material is used to manufacture items of motor vehicle equipment that are sold to vehicle owners for use in used vehicles (i.e., vehicles previously purchased in good faith for purposes other than resale), the felt need not meet Standard No. 302. In general, it would not violate Standard No. 302 to add aftermarket seat cushions to used vehicles, even if the addition of the seat cushions caused the vehicles to no longer comply with the standard. This general rule is, however, limited by the application of the provisions of section l08(a)(2)(A) of the Safety Act. That section specifies: "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 or item of motor vehicle equipment in compliance with an applicable Federal motor vehicle safety standard ..." The flammability resistance of the original vehicle is an element of design installed in a motor vehicle in compliance with Standard No. 302. Thus, any person in the aforementioned categories that installed a seat cushion which did not comply with the flammability resistance requirements of Standard No. 302 would be rendering inoperative that element of design, and thereby violating a section l08(a)(2)(A). Section l09 of the Act specifies a civil penalty of up to $l,000 for each violation of section l08. Again, the manufacturer of the aftermarket seat cushions would be obligated to recall and remedy cushions that are determined to contain a safety related defect, even if the cushions were installed by the vehicle owners themselves. You asked about other Federal laws that might have a bearing on the manufacture of the felt material. You might wish to contact the Occupational Safety and Health Administration at (202) 523-8148 and the Environmental Protection Agency at (202) 475-8040 for information about the applicability of any of their statutes and regulations. Sincerely,

ID: 2646oOpen The Honorable Leon E. Panetta Dear Mr. Panetta: This responds to your inquiry on behalf of Dr. Courtney F. Morgan, a constituent of yours. Dr. Morgan has purchased a 1987 model year Saab. The particular version of the model he saw at the dealership was equipped with manual lap/shoulder safety belts. However, the actual car that was delivered to Dr. Morgan was equipped with automatic safety belts. Dr. Morgan feels that the automatic belts are "hazardous and cumbersome," and asked what he must do in order to remove the automatic belts and have manual safety belts installed in place of the automatic belts. I am pleased to have this opportunity to explain our law and regulations to you. Pursuant to the National Traffic and Motor Vehicle Safety Act in 1966 (the Safety Act; 15 U.S.C. 1381 et seq.), a Federal safety standard on occupant crash protection was issued in 1967 requiring the installation of manual safety belts in all new passenger vehicles. Although these manual safety belts have shown their effectiveness as safety devices, only a relatively small number of motorists used their manual belts. As recently as 1984, only 12.5 percent of front seat occupants wore their manual belts. Because so few people used their manual safety belts, the Department issued the first requirement for automatic restraints in passenger cars in 1970, and it was scheduled to take effect in 1973. That implementation date was delayed for a variety of reasons. On June 24, 1983, the Supreme Court of the United States found our decision to repeal the requirement for automatic restraints was "arbitrary and capricious," and ordered us to reconsider the decision (Motor Vehicle Manufacturers Association v. State Farm Mutual Automobile Insurance Co., 463 U.S. 29). Against this background, former Secretary of Transportation Dole issued a final rule amending the Federal safety standard on occupant crash protection on July 17, 1984. That decision, which promotes both automatic restraints and State safety belt use laws, provides a comprehensive approach designed to save as many lives as possible as quickly as possible. We believe that effectively enforced State laws requiring the proper use of the manual safety belts that are in most cars on the road today offer our best opportunity to save lives today at virtually no cost to the consumer. The decision also reflects our belief in the value of automatic occupant protection systems, such as air bags and automatic belts, by requiring all new cars to have automatic protection starting with the 1990 model year. The automatic protection requirements are phased in during the preceding three model years, beginning with 10 percent of each manufacturer's 1987 model year cars. Each manufacturer must equip 25 percent of its 1988 model year cars with automatic occupant protection systems, and 40 percent of its 1989 model year cars with automatic occupant protection systems. However, if the Secretary determines not later than April 1, l989, that State belt use laws have been enacted that meet certain criteria and that are applicable to two-thirds of the U.S. population, then the automatic restraint requirements will be rescinded. The following prohibition appears in section 108 of the Safety Act: "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 Federal motor vehicle safety standard ..." In this case, the automatic safety belts in Dr. Morgan's Saab are a "device or element of design installed in a motor vehicle in compliance with an applicable Federal motor vehicle safety standard." Removal of the automatic belts would render them inoperative. Therefore, Federal law prohibits Saab, any other manufacturer, and any distributor, dealer, or motor vehicle repair business from removing the automatic safety belts from Dr. Morgan's car. Please note that this Federal prohibition does not prevent Dr. Morgan himself from removing the automatic belts from his car. However, we encourage vehicle owners not to tamper with the occupant crash protection systems installed in their vehicles. If Dr. Morgan were to remove the automatic belts himself and improperly install manual safety belts, he would be putting himself and other vehicle occupants at substantially greater risk of injury in a crash. Please thank Dr. Morgan for informing us of his views on this subject. We welcome the interest of all concerned citizens on this important subject and I appreciate this opportunity to advise you of our efforts to improve occupant crash protection for all Americans. Sincerely,

ID: 2647oOpen Mr. Allan J. Lameier RE: A. Lameier 513-684-3915 Dear Mr. Lameier: This is in response to your letter requesting clarification concerning the classification of a Davey mobile compressor. You state that the manufacturer of the compressor indicates that the wheeled compressor need not comply with Standard No. 108, Lamps, reflective devices and related equipment, because the compressor is not a trailer. Based on the information provided with your letter, we believe that the compressor is not a motor vehicle and is therefore not subject to the requirements of Standard No. 108 or any other Federal motor vehicle safety standards. By way of background, our agency is authorized, under the National Traffic and Motor Vehicle Safety Act of 1966 (Safety Act; 15 U.S.C. 1381 et seq.) to issue safety standards applicable to new motor vehicles and items of motor vehicle equipment. The National Highway Traffic Safety Administration (NHTSA) does not approve motor vehicles or motor vehicle equipment. Instead, the Safety Act establishes a "self-certification" process under which each manufacturer is responsible for certifying that its products meet all applicable safety standards. A "trailer" is defined at 49 CFR /571.3 as "a motor vehicle with or without motive power, designed for carrying persons or property and for being drawn by another motor vehicle." The mobile compressor shown in the brochure enclosed with your letter appears to be designed for carrying property (the compressor) and for being drawn by a motor vehicle. The answer to your question of whether this compressor is a trailer, then depends on whether the compressor is a "motor vehicle" within the meaning of the Safety Act. Section 102(3) of the Safety Act (15 U.S.C. 1391(3)) defines a "motor vehicle" as any 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. We have interpreted this language as follows. Vehicles such as forklifts and mobile construction equipment which are sold primarily for off-road use, but which incidentally use the public roads to travel from one job site to another, are not considered motor vehicles. On the other hand, vehicles which regularly use the public roads and stay off-road for only limited periods of time are motor vehicles and are subject to our safety standards. The agency has previously concluded in a July 1, 1980 letter to Mr. E.C. Elliott (copy enclosed) that his company's portable air compressors were not motor vehicles, based on statements that these devices spend the bulk of their useful lives on construction sites and are seldom drawn over public roads by mechanical power. If the Davey portable compressors are used in the same fashion as the compressors discussed in the July 1, 1980 letter, we believe that the Davey compressors were properly classified by the manufacturer as something other than a "motor vehicle". This means that the Davey compressors are not subject to any of the Federal motor vehicle safety standards. I hope this information has been useful. My apologies for the delay in responding to your letter. Sincerely,
