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: 17258.ztvOpenMr. Eric Williamson Dear Mr. Williamson: This is in reply to your letter of February 16, 1998, with respect to rear deck spoilers incorporating center highmounted stop lamps (CHMSLs). The spoiler with its lamp is designed for installation on vehicles whose original CHMSL is located in the rear window. This raises the question of whether the original CHMSL should be disconnected when the spoiler incorporating the new one is installed. By way of background, and to be brief about it, modifications may be made to new vehicles before their initial sale as long as the vehicles remain in compliance with the Federal motor vehicle safety standards to which their manufacturers have certified them. Because the addition of a spoiler may partially block the light output and visibility of a CHMSL located in the rear window, resulting in a noncompliance with the Federal motor vehicle safety standard on lighting (Standard No. 108), we have advised that, under these circumstances, a second CHMSL should be added that meets original equipment requirements. When the second CHMSL is added, the original CHMSL then becomes merely a supplemental stop lamp. Supplementary lighting is permitted under Standard No. 108, provided that it does not impair the effectiveness of any lighting equipment required by Standard No. 108. We do not believe that a supplementary CHMSL in the rear window impairs the effectiveness of a spoiler-mounted CHMSL. This means that, under Standard No. 108, there is no Federal law requiring the original CHMSL to be disconnected. However, Standard No. 108 does not apply to the use of vehicles on the public roads. Some states may require the original CHMSL to be disconnected when a spoiler-mounted CHMSL is provided. We are sorry that we are unable to advise you on the laws of the individual states. We note your comment that the spoiler includes "a D.O.T. approved rear brake lamp." This phrase is often mistakenly used to indicate a lamp that is designed to conform to the requirements of Standard No. 108. We assume that you meant a center stop lamp that will comply with all requirements of Standard No. 108 when it is installed on the vehicle. D.O.T. itself has no authority to "approve" or "not approve" any item of equipment and the phrase "D.O.T. approved" has no meaning and should not be used. If you have any questions, you may refer them to Taylor Vinson of this Office (202-366-5263). Sincerely, |

ID: 8731Open Mr. Richard J. Dessert Dear Mr. Dessert: This responds to your petition of May 28, 1993, to the Administrator for a temporary exemption for low emission motor vehicles that you would like to produce. These vehicles would be purchased by the Los Angeles Department of Water and Power (LADWP). The response deadline for LADWP's Request for Proposal (RFP) was June 1, 1993. You have informed us that "As part of LADWP requirements for successful bidders, evidence of progress towards obtaining Federal Motor Vehicle Safety Standards certification may be provided through demonstration that an application was made with NHTSA for a temporary exemption from Federal Motor Vehicle Safety Standards." Because this matter affects LADWP as well as Sun Cycle Company, we are sending a copy of this response to the designated LADWP contact, Jeffrey S. Silverstone. The National Highway Traffic Safety Administration (NHTSA) did not receive your petition until June 8, and therefore had no chance to advise you with respect to it before the RFP deadline of June 1. We must inform you that the petition does not meet our procedural requirements and is not accepted for processing and action. There are several areas in which the petition is deficient. Most importantly, it appears to be a request for a blanket exemption from compliance with all applicable Federal motor vehicle safety standards. While the applicable law and regulation do not forbid this, you should know that the Administrator has never entertained a petition of this breadth and in all probability would never grant one. An applicant for a low-emission vehicle exemption must provide sufficient information upon which the Administrator may find that an exemption would not unduly degrade the safety of the motor vehicle, and that the exemption is consistent with the public interest and the objectives of the National Traffic and Motor Vehicle Safety Act. We do not believe that the Administrator could make the requisite findings to support a blanket exemption. It is NHTSA's policy to encourage manufacturers to manufacture conforming vehicles to the extent possible, and to narrow the scope of their requests for exemption. Low-emission vehicle petitions generally cover four to 14 standards. As part of your argument, you must set forth each individual standard from which you request exemption, and provide a detailed description of how your vehicle differs from a conforming one. You must also provide reasons why an exemption from each standard for which request is made would not unduly degrade the safety of the vehicle, something more than the general statement you have made that the first prototypes will "substantially comply with all the safety standards." Finally, you must present your views why an exemption is in the public interest and consistent with the objectives of the Safety Act. When we have received a petition from you that fulfills these requirements, we shall be pleased to accept it for consideration and public comment. As the vehicle you intend to manufacture is completely unknown to NHTSA, your new petition should also contain photographs or descriptive literature illustrating it. Our closing comment is that you or the LADWP may be unclear about vehicle certification. A manufacturer does not "obtain" certification from NHTSA. The Safety Act establishes a self-certification scheme under which the manufacturer certifies its vehicles after satisfying itself that it conforms to the standards, aside from those from which it may have been exempted. It does not have to have permission from NHTSA to do so. You intend to test the vehicles, and such testing could provide substantiation for your certification of compliance, or, alternatively, substantiation to NHTSA that an exemption would not unduly degrade the vehicle's safety. If you have any questions about this matter, you may refer them to Taylor Vinson of this Office (202-366- 5263). Sincerely,
John Womack Acting Chief Counsel cc: Jeffrey S. Silverstone Los Angeles Department of Water and Power Attn: Electric Vehicle RFP P.O. Box 111 Los Angeles, CA 90051-0100 ref:555 d:1/11/94

ID: 1983-3.38OpenTYPE: INTERPRETATION-NHTSA DATE: 12/21/83 FROM: AUTHOR UNAVAILABLE; Frank Berndt; NHTSA TO: Mr. Jeff S. Brantner TITLE: FMVSS INTERPRETATION TEXT: This responds to your letter of November 9, 1983, to the Urban Mass Transit Administration, which was forwarded to this agency for reply, concerning legal requirements regulating window stickers. The following discussion addresses the Federal requirements applicable to sticker or other films applied to glazing materials in motor vehicles. The National Highway Traffic Safety Administration has the authority to govern the manufacture of new motor vehicles and motor vehicle equipment. Pursuant to the National Traffic and Motor Vehicle Safety Act, 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 (70 percent in areas requisite for driving visibility, which includes all windows in passenger cars) and abrasion resistance. The agency has stated in past interpretations that films such as the type referred to in your letter are not glazing materials themselves, and would not have to comply with Standard No. 205. However, installation of such films on new motor vehicles would be prohibited if the vehicle glazing no longer complied with the light transmittance or abrasion requirements of the standard. If a vehicle manufacturer or a 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. Section 108(a)(1) prohibits any person from offering for sale or selling any motor vehicle or equipment that fails to comply with applicable safety standards. After a new vehicle has been sold to the consumer, he may alter his vehicle as he pleases, so long as he adheres to all State requirements. Under Federal law, the owner could install the film on glazing in his vehicle whether or not such installation adversely affected the light transmittance and abrasion resistance of his vehicle's glazing. It should be noted, however, that section 108(a)(2)(A) of the National Traffic and Motor Vehicle Safety Act 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. "Render inoperative" means to remove, disconnect or degrade the performance of a system or element of design installed pursuant to the Federal safety standards. Thus, none of those persons may knowingly install a film on a vehicle for its owner if that act would render inoperative the light transmittance or abrasion resistance of the vehicle glazing. Whether this would be the case would have to be determined by the person making the installation. Violation of this section can result in Federal civil penalties up to $ 1,000 for each violation. Please contact Stephen Oesch of my staff if you have any further questions (202-426-1834). SINCERELY, Arthur E. Teele Jr. Urban Mass Trans. Admin. November 9, 1983 Dear Mr. Teele. I have designed an automobile sticker that I feel is very catchy and will hopefully be on the rear windows of a large number of vehicles. I do have a question though, regarding the legal size of a window sticker. My tentative design is three (3) inches high by sixteen (16) inches wide. I feel that the width is not as critical as the heighth as far as a visability restriction is concerned, yet I would like to keep it legal in order to avoid any trouble. I will appreciate any help that you can give me, since this means a great deal to me. Thank you, in advance, for your time and effort. Jeff Brantner |

ID: nht90-2.39OpenTYPE: Interpretation-NHTSA DATE: May 2, 1990 FROM: Stephen P. Wood -- Acting Chief Counsel., NHTSA TO: Earl W. Dahl -- Goodyear Tire & Rubber Company.,Vice President TITLE: None ATTACHMT: Attached to letter dated 1-31-90 To Stephen P. Wood and From Earl W. Dahl; Also attached to letter dated 5-31-89 To Garry Gallagher and From Erika Z. Jones TEXT: This responds to your letter seeking an interpretation of 49 CFR 574,Tire Identification and Recordkeeping. Specifically, you asked whether an additional symbol, which is intended to identify more precisely the year of manufacturer, is permitted to be in cluded in the tire identification number. As explained below, the answer is yes. The purpose of the tire identification requirements is to facilitate the effective recall of tires from the public if the tires are found not to comply with the applicable safety standards or if the tires contain a safety related defect. Section 574.5 re quires that each tire be marked with the tire identification number. In particular, it requires that the fourth grouping contain three numerals of which the first two identify the week of the year and the third numeral identifies the year of manufacture. You believe that this requirement may lead to confusion because the third numeral, e.g. "9", could refer to more than one year, e.g., 1979 or 1989. Accordingly, you state that your company would like to be able to distinguish the year of manufacture in an interval longer than one decade. To do this, you would like to add a symbol immediately following the fourth grouping of the tire identification number to identify that this tire was produced in the decade 1990 through 1999. Standard No. 109, New pneumatic tires (49 CFR S571.109) and Standard No. 119, New pneumatic tires for vehicles other than passenger cars (49 CFR S571.119) together with Part 574 require that, certain information be labeled on the sidewalls of each tire s ubject' to the standards. In a May 31, 1988 letter to Mr. Garry Gallagher of Metzeler Motorcycle Tire (copy attached), the agency explained that The agency has frequently stated in past interpretations that the purpose of these labeling requirements is to provide the consumer, in a clear and straightforward manner, with technical information for the safe use of the tires. (These standards) permit tire manufacturers to label additional information on the sidewall on the tires, provided that the additional information does not obscure or confuse the meaning of the required information, or otherwise defeat its purpose. Applying this standard to the question you have asked, we believe that the additional symbol, an isosceles right triangle, is not prohibited from appearing on the sidewall of your company's tires. As explained above, the labeling requirements are intende d to provide information about the tire, including the year of manufacture, in a clear and straightforward manner. Because the suggested symbol does not appear to introduce additional information that might obscure or confuse tbe meaning of the required information or otherwise defeat its purpose, the agency has determined that marking a tire with an isosceles right triangle after the tire identification code is not prohibited. |

ID: nht95-2.57OpenTYPE: INTERPRETATION-NHTSA DATE: April 27, 1995 FROM: Mayo D. Tubbs -- Visionary Lighting Systems TO: Philip Recht -- Acting Deputy Administrator, NHTSA TITLE: Revised High-Technology Lighting System for the Trucking Industry ATTACHMT: ATTACHED TO 6/9/95 LETTER FROM JOHN WOMACK TO MAYO D. TUBBS -- (A43; STD. 108) TEXT: Dear Mr. Recht: I was disappointed to ascertain from your correspondence dated April 13, 1995 that my color selection of Aviation Green for the strip lighting system would not conform to Standard No. 108. While I feel strongly that the unique green color would incre ase drivers' visual acuity and enhance identification of trailers in low light and inclement weather conditions, the system is not limited to the color green. Subsequent discussions with Mr. Taylor Vinson concerning the use of amber and red colored stri p lights indicate the system may comply with Standard No. 108 if these colors were utilized in lieu of green. Attachment A provides color locations of the strip lights. Selection of the proper red and amber colors will conform to CIE 1931 and 1976 UCS Chromaticity Diagrams. Amber will be in the 580 nanometer range while red will be in the 610 nanometer range. All other system specifications remain the same as the original design. Light output will be in the 4fL range, the system power input requirement will be less than 1 amp D.C. and the physical shape of the lights will be the same. The inherent safety f eatures of the previously submitted lighting system will apply to red and green strip lights also. Concerning the physical locations of the strip lights and the possible interference with the conspicuity reflective tape along the sides and rear of the trailer. I understand that covering or partial obscuration of the reflectivity tape will decrease tape effectiveness and consideration will be given in selecting proper areas of strip light installation. Mr. Taylor noted that new production trailers must have the reflective tape installed at the top, rear of the trailer in accordance with S5.7. Mo st trailers provide sufficient area to accommodate both the tape and the strip lights. If not, then no lights would be installed in this area. Attachment B provides additional information. It is my understanding that if a trailer manufacturer installs the three identification lights at the top, rear of the trailer, then the clearance lights can be installed at the bottom of the trailer. If the identification lights are mounted at the b ottom of the trailer, then the clearance lights must be at the top, rear. See attachment C. To provide a better understanding of this technology and the proposed lighting system, I can provide an on-site demonstration for the NHTSA and for George Parker of the Office of Research and Development. I hope that this information concerning the revised lighting system will provide your office wilh sufficient data to evaluate the system and rule that it is in compliance with the requirements of 49 U.S.C. 30112(a). Thank you for your time and consideration and I look forward to receiving your letter. (Attachments A-C omitted.) |

ID: 24579OpenMr. Tom Peterson Dear Mr. Peterson: This responds to your letter dated June 18, 2002, concerning a King Heavy Equipment Military Trailer Model GTS 100 which Oshkosh Truck imported on June 30, 1999, as a prototype trailer for testing and training purposes. The trailer was imported under a Temporary Import Bond, which has had two annual extensions. The 3-year limit is June 30, 2002. You would like to keep the trailer in the U.S. for further testing and training, and suggested that it might be "reclassified to off-road usage only." You indicated in a telephone conversation with a member of my staff that the further testing and training would relate to military use. As discussed below, while we doubt the vehicle could be considered an off-road vehicle,[1] we believe, based on the facts provided in your letter, that the trailer can remain in the U.S. under 49 CFR 571.7(c). According to your letter, the trailer in question was designed and built in the UK strictly for military usage. Oshkosh Truck designed the trailer specifically to operate with the Oshkosh M1070 Heavy Equipment Transporter (HET) tractor for carriage of main battle tanks up to 72 tons in weight, or to carry two lighter armored vehicles up to 36 tons each. Oshkosh Truck won a bid to build 92 UK HET tractor/trailer combinations and the trailer was built as a prototype as part of the building process. Since the trailer has been in the United States, it has been hauled on a commercial double-drop trailer to various proving grounds, including the Aberdeen proving grounds in Maryland, for testing purposes. Under 49 CFR 571.7(c), no Federal motor vehicle standard applies to a vehicle or item of equipment manufactured for, and sold directly to, the Armed Forces of the United States in conformity with contractual specifications. In a letter to Oshkosh Truck dated July 3, 1986, we stated that while this exception applies only to vehicles manufactured for sale, the agency had no objection to limited use on the public roads of nonconforming prototype vehicles that have been developed expressly for sale to the Armed Forces of the United States. We believe the situation you describe is sufficiently close to that described in 571.7(c) and our July 3, 1986, letter that the prototype King Heavy Equipment Military Trailer Model GTS 100 can remain in the U.S. under that section. I emphasize, however, that this opinion is limited to the specific factual situation involving this vehicle and should not be considered as precedent as to how we might treat other situations. I note that we would not apply this section to individuals importing surplus military vehicles. I hope this information is helpful. If you have any further questions, please feel free to contact Edward Glancy of my staff at 202-366-2992. Sincerely,
[1] According to information provided with your letter, in designing the vehicle, attention was paid "to meet existing and known future transport legislation to meet the anticipated peacetime movement requirements." More specifically, the semi-trailer was designed to meet European requirements for the movement of heavy loads with the ability to negotiate compliant surfaces and maintain a degree of "off-highway" capability. (Emphasis added.) Thus, while Oshkosh Truck may not plan to use this particular trailer on the U.S. highways, it does not appear to be an off-road vehicle. |
