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: 07-26-01_Rubel_ltr_spwOpen Eric A. Rubel, Esq. Dear Mr. Rubel: This is in reply to your letter, written on behalf of DEKA Research and Development Corporation (DEKA), asking whether certain products would be considered "motor vehicles" subject to regulation by this agency. You generally described the products. You stated that the products in question, which to date have not been marketed or sold, would have either two or four drive wheels, would operate on battery power, and would be intended primarily for use on sidewalks. You also stated that the products could be described as low-speed electric personal assistive mobility devices, which are self-balancing, can operate on two non-tandem wheels, have an electric propulsion system, and have a maximum speed on a paved level surface of less than 20 mph, when powered solely by such a propulsion system and ridden by an operator who weighs 170 pounds. As you know, the National Highway Traffic Safety Administration regulates "motor vehicles." A "motor vehicle" is defined, in part, as one "manufactured primarily for use on the public streets, roads, and highways." 49 U.S.C. ' 30102(a)(6). Accordingly, only vehicles which are operated on the public streets, roads, and highways, as one of their primary uses, are considered to be motor vehicles. In determining whether a particular product is operated on the public streets, roads, and highways, as one of its primary uses, we consider a number of factors, including whether the vehicle can be licensed for use on public streets, roads and highways. If a vehicle cannot be so licensed, we consider whether the vehicle is, in fact, used on public streets, roads, and highways by a substantial number of people. Considering that the vehicles you describe are still in the planning stage (i.e., are not presently available for sale to the general public), no data are available concerning their actual use. In situations like this, where such data are unavailable, this agency has looked to the use patterns of vehicles similar to the ones in development. Given the general nature of the description, identifying like-vehicles is difficult. This problem is compounded by the fact that the vehicles DEKA is planning to manufacture appear to be unique. Nevertheless, we note that they have characteristics that, at least in some respects, are similar to those of motorized wheelchairs. This agency does not consider motorized wheelchairs to be "motor vehicles." They are not licensable and are not used on public streets, roads, and highways by a substantial number of people. Thus, they are not subject to this agency's safety regulations. Based on our understanding of the characteristics of the vehicles in question and on the assumptions that they would not be licensable and would be used in a fashion similar to motorized wheelchairs, we would not consider the vehicles to be "motor vehicles." If our assumptions about licensability and actual usage proved incorrect, we would reconsider this position. If you have any questions, you may contact Robert Knop of this Office at (202) 366-2992. Sincerely, John Womack ref:571 |

ID: 0705rOpen Mr. Jeffrey D. Shetler Dear Mr. Shetler: This responds to your letter of February 2, 1995, asking whether Safety Standards Nos. 108 and 123 permit a motorcycle turn signal pilot indicator to be green. You have noted that, under Table III of Standard No. 108, SAE J588 NOV84 is the appropriate standard that the National Highway Traffic Safety Administration (NHTSA) has incorporated by reference for motorcycle turn signal lamps. You have further noted that the SAE standard specifies requirements for turn signal pilot indicators if the front turn signal lamps are not readily visible to the driver. Finally, paragraph 5.4.3.3 of SAE J588 specifies that the indicator, if located on the outside of the vehicle, should emit a yellow-colored light. On the other hand, Standard No. 123, which specifies requirements for turn signal lamp identification, does not specify a color for turn signal pilot indicators. You believe that SAE J588 was written with passenger cars in mind and that its color and area requirements are specified because the location of an outside indicator lamp is further away than a lamp located inside the vehicle on the instrument panel. You also believe that Standard No. 123 does not need to address distance from the driver's eye because the turn signal lamp will always be within a reasonable distance from the driver's eye. Thus, you have concluded that any pilot lamp color would be acceptable. We have reviewed specifications of both the SAE and Standard No. 123. SAE J588 NOV84 Turn Signal Lamps for Use on Motor Vehicles Less Than 2032 MM in Overall Width is incorporated by reference in Standard No. 108, and, under Table III, is the standard specified for motorcycle turn signal lamps. Because paragraph S5.1.1 of Standard No. 108 does not contain a section modifying the applicability of J588 to motorcycles, all the requirements of J588 apply to motorcycles, including turn signal pilot indicators and their color. All that Standard No. 123 does, through Table III, is to specify the shape of the turn signal indicator. It is silent as to the color of the indicator. We believe that you are correct in your conclusion that J588 was not written with motorcycles in mind, at least for two-wheeled motorcycles such as Kawasaki makes. Two colors are prescribed by SAE J588, the choice of which depends on the location of the indicator. Under paragraph 5.4.3.2, a green-colored light "with a minimum area of 18 sq. mm." must be used "if the illuminated indicator is located inside the vehicle." Under 5.4.3.3 a yellow-colored light with "a minimum projected illuminated area of 60 sq. mm." must be used "if the illuminated indicators are located on the outside of the vehicle, for example on the front fenders." Since two-wheeled motorcycles do not have enclosed cabins, all references to "inside" and "outside" the vehicle are inapposite. Since you brought this matter to our attention, we have conducted an informal survey of the color of turn signal indicators on motorcycles sold in the United States. We find that the predominant color is amber, though Harley-Davidson, accounting for 12% of the market, uses green. We view the use of either color as in accord with J588. Therefore, if Kawasaki wishes to change its indicator color from amber to green, it will not violate Standard No. 108 by doing so. As J588's color specifications are coupled with those for the minimum illuminated area of the display, and you have not raised the question of an appropriate size for a green turn signal indicator, we call your attention to paragraph S5.2.2 of Standard No. 123 which requires that the display for turn signal lamps and other equipment "be visible to a seated operator under daylight conditions." If you have any further questions, Taylor Vinson of this office will be glad to answer them for you (202- 366-5263). Sincerely,
John Womack Acting Chief Counsel ref:108 d:5/3/95

ID: 0722Open Herr Tilman Spingler Dear Herr Spingler: We have received your FAX of February 15, 1995, asking whether a proposed design "for a lens-reflector-joint can be considered as conforming to the appropriate definition in FMVSS 108." The agency does not advise manufacturers whether particular designs are regarded as "conforming." That determination is to be made by the manufacturer in certifying that its product conforms to all applicable Federal Motor Vehicle Safety Standards. However, we can provide you with an interpretive guideline. Section S4 defines a "replaceable bulb headlamp" as a headlamp "comprising a bonded lens reflector assembly and one or two replaceable light sources." The intent of the definition was that the lens and reflector assembly be an indivisible unit upon manufacture of the headlamp. This means that, if a lens is broken, the entire lens reflector assembly must be replaced. If your design is such that the lens cannot be removed from the reflector assembly for replacement, it would appear to meet the definition in S4. As you are well aware, NHTSA granted your company's petition for rulemaking, and, in November 1994, proposed an amendment of the definition of "replaceable bulb headlamp" that would allow a replaceable lens if the headlamp incorporates a vehicle headlamp aiming device conforming to S7.8.5.2. Comments were due on this proposal February 21, 1995. In due course, after review of the comments, NHTSA will decide whether it will pursue further rulemaking or terminate the rulemaking action. Sincerely,
Philip R. Recht Chief Counsel ref:108 d:3/8/95

ID: 0761Open Mr. Chong D. Lee Dear Mr. Lee: This is in reply to your FAX of February 28, 1995, asking several questions about the importation and sale of an aftermarket airbag. The airbag "comes in assembly with a steering wheel" and is intended for installation in vehicles not originally equipped with a driver's airbag. You have asked the following questions: "a) Whether such a product as described is legal for U.S. sale." There is no Federal prohibition per se against the sale of aftermarket airbags. However, pressure vessels and explosive devices for use in airbag systems must comply with section S9 of Standard No. 208, even if they are aftermarket equipment. Therefore the manufacturer of these items (or the importer, who is defined as a "manufacturer" under our statute) must certify that they comply with the requirements of S9 of Standard No. 208. S9 prescribes performance requirements that are found in 49 CFR secs. 173 and 178, regulations of another Administration of the Department of Transportation. We suggest that you write the Associate Administrator for Hazardous Materials Safety, Research and Special Programs Administration, 400 7th Street, Washington, D.C. 20590 for an opinion as to whether other of its regulations apply to your product or its movement in interstate commerce. As to whether the laws of the individual States regulate the sale of aftermarket airbags, you should write, for an opinion, the American Association of Motor Vehicle Administrators, 4600 Wilson Boulevard, Arlington, Va. 22203. "b) Legal procedures, testing or submissions required to certify the product for U.S. sale." The requirements for compliance with S9 of Standard No. 208 are set forth in 49 CFR secs. 173 and 178. When the manufacturer who is responsible for certifying compliance is satisfied that the equipment, in fact, does conform, it certifies the product. At that point, pressure vessels and explosive devices that are part of an airbag assembly, if not manufactured in the United States, may be imported into this country. A state is not permitted to have performance requirements for pressure vessels and explosive devices that differ from those of S9, but it may have a standard requiring identical performance, and, if so, they may ask for documentary assurance of compliance. "c) Applicable Federal law (e.g. FMVSS 208)." See replies to your previous questions. You should also note that an aftermarket airbag is "motor vehicle equipment" within the meaning of the U.S. Code. Therefore, if the air bag contained a defect (either in manufacture, design, or performance) that relates to motor vehicle safety, the manufacturer would be required to conduct a recall campaign to notify owners and to remedy the defect free of charge. One Federal law does bear upon the installation of the airbag. It is a violation of 49 U.S.C. 30122 if a manufacturer, distributor, dealer, or motor vehicle repair business replaces a piece of original equipment that was necessary for compliance with a Federal motor vehicle safety standard, if the replacement part creates a noncompliance with that standard. The design of the steering wheel may affect compliance with Federal Standards Nos. 203 Impact protection for the driver from the steering control system and 204 Steering control rearward displacement. We recommend that you satisfy yourself that installation of the airbag will not affect the previous ability to comply, of the vehicle in which it is installed, before marketing the product. "d) Actions or registrations required to reduce legal risks." We are not in a position to advise you on matters that do not relate to Federal laws that we administer. We recommend that you consult a private attorney on these matters. "e) Any other information of which we should be aware." You should encounter no difficulties in importing the airbag and steering wheel under our importation regulation, 49 CFR Part 591 as long as any components that are required to comply with S9 of Standard No. 208 are certified as meeting that standard. I am enclosing an information sheet that outlines the various laws and regulations that we administer pertaining to motor vehicles and equipment with the thought that you might find it helpful. Sincerely, Philip R. Recht Chief Counsel Enclosure ref:208 d:4/10/95

ID: 0784Open Mr. Marshall S. Reagle Dear Mr. Reagle: This is in reply to your recent FAX to Pat Boyd of this agency asking for a confirmation of an interpretation of certain reflex reflector requirements of Motor Vehicle Safety Standard No. 108, specifically S5.7.2.1(b) and (c). For your future reference, requests for interpretation should be addressed to the Chief Counsel. You state that Mr. Boyd informed you that "any retro- reflector would have to be made in intervals of 4 inches" with the 0 degree at the two-inch mark, and that the reflective reading would have to comply with S5.7.2.1(b) or (c). He also informed you that, regardless of whether the segment was 4, 8, or 12 inches in length, the agency will test in 4-inch segments. This is correct. According to paragraph S5.7.2.2(a) and (b) of Standard No. 108, each reflector shall be installed "with the center of each reflector not more than 100 mm from the center of each adjacent reflector." As 100 mm is approximately 4 inches, this effectively limits the size of a reflector to a maximum length of 4 inches. However, this does not prohibit the mounting of two or three adjacent reflectors in "segments" of 8 or 12 inches, whether separately or in a housing. As Mr. Boyd informed you, each discrete 4- inch segment must comply with paragraph S5.7.2.1(b) or (c). Paragraphs S5.7.2.1(b) and (c) specify reflectivity values for red and white reflex reflectors respectively "at any light entrance angle between 30 degrees left and 30 degrees right, including an entrance angle of 0 degrees," as well as "any light entrance angle between 45 degrees left and 45 degrees right." Your drawing of a 4-inch reflector correctly depicts the 0 degree light entrance angle at the 2-inch mark, in the center of the reflector. However, SAE Standard J594f, Reflex Reflectors, January 1977, incorporated by reference in Standard No. 108, requires the measurement of the other light entrance angles also with respect to the center of the reflector, rather than with respect to the ends as pictured in your drawing. If you have any further questions, you may call Taylor Vinson of this Office (202-366-5263). Sincerely, Philip R. Recht Chief Counsel ref:108 d:4/17/95

ID: 0787Open Mr. Dirk du Plooy Dear Mr. du Plooy: We have received your letter of March 6, 1995, to Joe Pesci of this agency, asking his assistance "in acquiring information about U.S. laws on motorcycle trailers." You understand that "there could be a number of different U.S. states with different laws, but the most generally accepted standard" is what you are seeking in drafting legislation legalizing motorcycle trailers. Any trailer that is manufactured for sale in, or imported into, the United States must comply with all applicable Federal motor vehicle safety standards. These standards are issued by this agency. Several of them apply to trailers. As we have no separate category of "motorcycle trailer", these standards would apply to any trailer manufactured for the purpose of carrying one or more motorcycles. Here are the requirements that apply to trailers. A trailer with a hydraulic brake system must be equipped with brake hoses, brake hose assemblies, and brake hose end fittings that meet Standard No. 106, and with brake fluid that complies with Standard No. 116. Lighting equipment and reflectors must be installed pursuant to Standard No. 108. Each trailer must have a Vehicle Identification Number attached, in accordance with Standard No. 115 to facilitate any recall campaigns for safety purposes. Standards Nos. 119 and 120 apply to tires and rims used on trailers. Finally, at the end of the manufacturing process, the manufacturer must affix a permanent label which certifies that the trailer complies with the safety standards. Because these Federal standards apply throughout the United States, I believe that they meet your request for information on "the most generally accepted standard." Under our laws, if any State has its own standard covering any aspect of performance that is covered by one of the Federal standards listed above, that State standard must be identical to the Federal one. So, to that extent, State regulation of motorcycle trailers should be identical to the Federal requirements. However, States may impose their own standards in areas that are not covered by the Federal standards. For example, this agency has no requirement covering strength of trailer hitches, or that trailers be equipped with mud flaps. Therefore, a State could adopt standards in these areas. We are not conversant with State laws for motorcycle trailers, and cannot advise you about them. If you wish further information on such laws, we recommend that you write the American Association of Motor Vehicle Administrators, 4600 Wilson Boulevard, Arlington, Va. 22203. I am enclosing for your information a pamphlet on our regulations that we provide to prospective trailer manufacturers. We shall be pleased to answer any further questions you may have. Given the distance between us, you may wish to communicate by FAX. Our number is 202-366-3820. Sincerely,
Philip R. Recht Chief Counsel Enclosure ref:571 d:4/10/95

ID: 0788Open Mr. Dietmar K. Haenchen Dear Mr. Haenchen: This responds to your letter of March 6, 1995, asking for an interpretation of the license plate requirements of Standard No. 108. SAE J587 OCT81 is the SAE standard that has been incorporated by reference into Standard No. 108 for license plate lamps. You ask for confirmation of your interpretation that "paragraph 6.1 of SAE J587, which relates solely to the mounting angle of the license plate and not to the performance of the license plate lamp, is not included in the requirements of FMVSS 108." This paragraph requires that, when the license plate lamp is mounted on the vehicle, the angle between the plane of the license plate and the plane on which the vehicle stands will be 90 degrees plus or minus 15 degrees. You believe that "license plate mounting for visibility is a matter of concern for State law enforcement agencies and Volkswagen is not aware of any State laws that make reference to SAE J587 or that specify the mounting angle of the license plate." However, you acknowledge "that paragraphs 6.5 and 6.6 of SAE J587 specifying the angle of incidence of the lamp to the plate at a minimum of 8 degrees is part of FMVSS 108 and is intended to assure that the lamp illuminates the license plate." You believe "that a design which meets the 8 degree requirement and in which the plate is mounted so as to be clearly visible to an observer at the rear of the vehicle meets the intent and requirements of State laws and FMVSS 108, even if the angle of the plate itself is 15 degrees from the vertical." We cannot agree with your interpretation. Tables I and III have incorporated SAE J587 in its entirety, and there is no exclusion of paragraph 6.1 in Standard No. 108. To be sure, a plate may continue to be visible when it is mounted more than 15 degrees from the vertical, but the 15 degree limitation of paragraph 6.1 is necessary to ensure its legibility as well. The fact that the States and the Uniform Vehicle Code are silent on the point is legally irrelevant. If a State has a license plate mounting requirement, 49 U.S.C. 30103 requires it to be identical to the Federal requirement. If you have any further questions, you may refer them to Taylor Vinson of this Office (202-366-5263). Sincerely, Philip R. Recht Acting Chief Counsel ref:108 d:4/24/95

ID: 0789bOpen Mr. Jeffrey Echt Dear Mr. Echt: We have received your letter of March 10, 1995, asking whether it is permissible under Standard No. 108 to use the hazard warning lamps as a deceleration warning system. Paragraph S5.5.10(a) states that "Turn signal lamps, hazard warning signal lamps, and school bus warning lamps shall be wired to flash." With this in mind, "and the fact that hazard warning indicators are commonly used to warn high-speed trailing traffic that a leading vehicle or vehicles are moving slowly or stopped", you have asked: "1. Would a device which automatically activated a vehicle's hazard warning system at the onset of high, braking induced deceleration and deactivated the hazard warning system upon release of the brake pedal (following automatic activation) be permissible under FMVSS 108? This assumes that the device will not prevent activation or cause deactivation of the hazard warning system if the mandatory vehicular hazard warning signal operating unit has been activated by the driver." Heretofore, the agency's opinion letters on deceleration warning systems have covered those that operate through lamps that are steady burning in use (to Norman H. Dankert on June 3, 1990, and to Bob Abernethy on September 7, 1990), or through original equipment lamps that are additional to those required by the standard (letter of July 30, 1993, to the Commonwealth of Virginia). In those instances, we have advised that a deceleration warning system must be steady burning in use. Your question raises the issue of whether a flashing deceleration warning system is acceptable if it operates through original equipment lamps that are intended to flash when they are used. Flexible asked a similar question with respect to a supplementary lighting system. We advised it (letter of December 8, 1986) that simultaneous use of flashing and steady-burning lamps have the potential for creating confusion in vehicles to the rear and impairing the effectivess of the required stop lamps within the meaning of S5.1.3 (the provision of Standard No. 108 that governs the permissibility of supplemental original lighting equipment). We believe that the same conclusion also applies to wiring the hazard warning system to operate as a high deceleration warning system as well. Thus, we do not view this system as permissible under Standard No. 108. Obviously, complying vehicles are manufactured so that it is possible for a driver to simultaneously activate the hazard warning system and stop lamp system. However, we believe that this happens infrequently, and when it does, it is a conscious choice of the operator and not of a system. Because of the conclusion we have reached above, your second question is moot. Sincerely,
Philip R. Recht Acting Chief Counsel ref:108 d:4/24/95

ID: 0797Open Mr. Bill Lieb Dear Mr. Lieb: This is in reply to your letter of February 27, 1995. You report that "a manufacturer of sealed beam automotive head lamps . . . was told by [an adhesive supplier]. . . that D.O.T. 'approval' is required prior to changing the adhesive used on head lamps." Subsequently, you were told by Blane Laubis of this agency "that D.O.T. does not test, approve, or specify any adhesives, but just verifies that the completed unit meets the prescribed standards, and passes the appropriate tests." You ask if this is correct. Mr. Laubis is correct. Federal Motor Vehicle Safety Standard No. 108 Lamps, Reflective Devices and Associated Equipment establishes requirements that must be met by sealed beam headlamps. As you learned in your review, Standard No. 108 contains no specifications for adhesives. This means the manufacturer may choose the adhesive that appears best suited to ensuring that its particular sealed beam headlamp complies with the performance requirements of Standard No. 108. The approval of the agency is not required. The agency frequently buys and tests all types of headlamps as part of its compliance enforcement program. I hope that this letter is sufficient for your purposes. Sincerely,

ID: 08-000151 to Trinity-NobleOpenNovember 10, 2008 Mr. Joseph Brennan President Trinity-Noble LLC 12 Scarlet Oak Drive Doylestown, PA 18901 Dear Mr. Brennan: This responds to your letter asking about the Federal motor vehicle safety standards (FMVSSs) in connection with a product you have developed called Celltinel. According to your letter, this device would disrupt cell phone signals while the vehicle engine is running. You stated that it could be used to prevent the use of cell phones during driving by school bus drivers and also by teenage drivers. In a telephone conversation with Dorothy Nakama of my staff, you explained that you plan to market the Celltinel both as original equipment for new motor vehicles and as after-market equipment. You also explained that since it would be hard-wired into the motor vehicle, the product is not portable. You asked whether the product would interfere with any motor vehicle safety equipment on board a bus or car. The issues raised by your letter are addressed below. By way of background information, Congress has authorized the National Highway Traffic Safety Administration (NHTSA) to issue FMVSSs applicable to new motor vehicles and items of motor vehicle equipment. NHTSA, however, does not approve or endorse motor vehicles or motor vehicle equipment. Instead, the statute establishes a "self-certification" process under which each manufacturer is responsible for certifying that its products meet all applicable safety standards. Your device would be considered to be an item of motor vehicle equipment. None of our safety standards would apply directly to your product. However, if a device such as the Celltinel was installed as original equipment on a new vehicle, the vehicle manufacturer would be required to certify that, with the device installed, the vehicle satisfies the requirements of all applicable FMVSSs. If the device was added to a previously certified new motor vehicle prior to its first sale, the person who modified the vehicle would be an alterer of a previously certified motor vehicle and would be required to certify that, as altered, the vehicle continued to comply with all of the safety standards affected by the alteration. In addition, manufacturers, distributors, dealers, or motor vehicle repair businesses modifying a new or used vehicle are prohibited by 49 U.S.C. 30122 from knowingly making 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 FMVSS. Manufacturers of motor vehicle equipment are subject to the requirements of 49 U.S.C. 30118-30121 concerning the recall and remedy of products with safety related defects. In the event the manufacturer or NHTSA determined that your product contains a safety-related defect, the manufacturer would be responsible for notifying purchasers of the defective equipment and remedying the problem free of charge. See also 49 CFR Part 573, Defect and Non-Compliance Responsibility and Reports. In your letter, you asked whether your product would interfere with any motor vehicle safety equipment on board a bus or car. We are not able to provide analysis in this area, but would encourage you to carefully analyze this issue. We also suggest that you consider the devices effect on the ability to place 911 emergency calls from vehicles, which may be necessary when the engine is running. Finally, I note that because your product would use a weak disruptive signal to jam cell phones, laws enforced by the Federal Communications Commission may apply. I hope this information is helpful. I am also enclosing a fact sheet entitled Information for New Manufacturers of Motor Vehicles and Motor Vehicle Equipment. If you have any further questions, please feel free to contact Ms. Dorothy Nakama at this address or by telephone at (202) 366-2992. Sincerely yours, [signed by Stephen P. Wood for] Anthony M.
