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.

You asked whether the lessor or the lessee is the proper person to sign the original title application and odometer disclosure in a state such as Washington, which shows the lessee as the registered owner on the title and requires the lessee to sign the title application at the dealership. You also noted that in most cases the yearly license renewal is mailed to the lessee, and that the registered owner or lessee is liable in any legal action involving the vehicle. Mr. Morse's response, that the lessee is the person who is responsible for acknowledging receipt of the odometer disclosure when the lessee is considered by the state to be the registered owner of the vehicle, is correct. If you have any further questions about the Federal odometer disclosure law, please write to this office at the above address, or call Eileen Leahy, an attorney on my staff, at 202-366-5263. |

Dairymple, Safety Standard Engineer, NHTSA TITLE: NONE ATTACHMT: ATTACHED TO 5/1/95 LETTER FROM JOHN WOMACK TO CHARLES TUCKER (A43; Std. 208; VSA 108(a)(2)(A)) TEXT: Dear Ms. Gayle D. Dairymple, I asked the company that is making the modifications to my van, Fitzpatrick Enterprises, and they said I need to get a letter from you stating they are allowed to replace the factory installed steering wheel with the smaller ASTECH steering wheel with out an air bag. The EGB II with the ASTECH steering wheel is the only way I will be able to drive. Steve Manson, from Fitzpatrick Enterprises, Columbus, Ohio, asked me to write you and ask for permission to have my van modified with a smaller ASTECH steering wheel which does not have an airbag. Because my Range-Of-Motion (ROM) is limited from Mult iple Sclerosis, the smaller steering wheel improves my ability to drive safely. Because RSC is doing the modification and the RSC policy is that, "all vehicles they modify must have an air bag", I will have to pay for the small steering wheel without an airbag. Fitzpatrick needs your written permission to install the steering wh eel that is best and safest for me, but doesn't come with an air bag. With the standard size steering wheel that came on the van, I have to move my arm too much for me to steer, and although "it's" a perfectly good steering wheel, it's too awkward for m e and isn't safe for me to drive with anymore. The people in Ohio connected with my case, who can verify my need for a smaller steering wheel, and who have evaluated me, and have stated and written to me, that I will be a safe driver with the ASTECH steering wheel are: 1. Bob Farrell - at RSC ins pected my van and made recommendations, 2. Terrie Jones - at RSC is my counselor, 3. Dan Cox - at OSU did the clinical evaluation and the driver evaluation, 4. Dr. Kotil Rammohan & Dr. Joanne Lynn - at OSU Hospital are my doctors. A complete list wit h more names and addresses on page two. IN CONCLUSION, I AM ASKING YOU FOR A LETTER THAT STATES: FITZPATRICK ENTERPRISES IS ALLOWED TO MODIFY MY VAN, WITHOUT PUTTING IN AN AIRBAG. Please call me if there is any other information about my [Illegible Words] you need and I can supply you with. I will be very happy to do whatever I can as it [Illegible Words] years since I've had a vehicle I can drive.

ID: nht95-2.90OpenTYPE: INTERPRETATION-NHTSA DATE: May 19, 1995 FROM: John Womack -- Acting Chief Counsel, NHTSA TO: Donnell W. Morrison TITLE: NONE ATTACHMT: ATTACHED TO 4/25/95 LETTER FROM DONNELL W. MORRISON TO PHILIP R. RECHT TEXT: Dear Mr. Morrison: This is in reply to your letter of April 25, 1995, asking for a clarification of the letter of April 10 to you from the former Chief Counsel, Philip Recht. He explained Standard No. 108's requirements for the location of rear lighting on wide vehicles. As the letter stated, identification lamps are to be mounted "as close to the top of the vehicle as practicable." You speak of having seen "semitrailers on the highway with all the rear lights at bed level" including clearance and identification lamps. As the letter also stated, the determination of practicability is initially that of the manufacturer, to be made in its certification that the vehicle meets all applicable Federal motor vehicle safety standards. NHTSA will not question that determinatio n unless it appears clearly erroneous. Without further information on the semitrailers you saw, we cannot judge whether mounting the clearance and identification lamps at bed level was a clearly erroneous determination by the trailer's manufacturer. There are some configurations where there is no header on which to mount lamps and the top of the doors approaches the top of the vehicle. In those configurations, we would not contest the manufacturer's determination that mounting the lamps at bed level was "as close to the top of the vehicle as practicable." On the other hand, the semitrailers you saw might have failed to conform to Standard No. 108. I hope that this clarifies the matter for you. If you have any further questions you may call Taylor Vinson of this Office (202-366-5263). |

ID: nht95-2.91OpenTYPE: INTERPRETATION-NHTSA DATE: May 19, 1995 FROM: Milford R. Bennett -- Director, Safety Affairs, Safety & Restraints Center, General Motors; Signature by F. Laux TO: John Womack, Esq. -- Acting Chief Counsel, NHTSA TITLE: Subject: Request for FMVSS 205 Interpretation; USG 3183 ATTACHMT: ATTACHED TO 9/19/95 LETTER FROM JOHN WOMACK TO MILFORD BENNETT (A43; REDBOOK 2; STD. 205) TEXT: Dear Mr. Womack: The purpose of this letter is to request an interpretation of FMVSS 205. Specifically, General Motors seeks the agency's concurrence that a vehicle equipped with a particular rear window sunshade meets the light transmissibility requirements of FMVSS 205 . General Motors plans to offer a rear window sunshade in a near-future Cadillac model. The sunshade is a screen-like device that significantly reduces the light and heat load entering through the backlite. In its raised position, the sunshade covers app roximately 90% of the backlite area, and the light transmissibility through the combined backlite and sunshade is less than 70%. In its retracted position, the sunshade is stowed in the panel shelf area below the backlite, such that no portion of the bac klite is obscured. A driver operated switch on the instrument panel is used to electrically raise and lower the sunshade. FMVSS 205 requires a minimum of 70% light transmissibility through glazing that is requisite for driving visibility. The agency has historically interpreted the backlite of passenger cars to be requisite for driving visibility. General Motors seeks the Chief Counsel's interpretation that the proposed sunshade comports with the transmissibility requirements of FMVSS 205. Our reasons for believing that a vehicle equipped with the sunshade would continue to comply with FMVSS 205 are summarized as follow s: * The rear window sunshade would have no adverse effect on motor vehicle safety. As with conventional windshield sunvisors, drivers can be expected to utilize the sunshade in a way that will maximize, rather than diminish, driving safety and comfort. Wi th the sunshade in its raised position, trailing vehicles and other objects are readily visible through the screen mesh. Driver and passenger side outside rearview mirrors further provide for rearward visibility, comparable to other passenger carrying v ehicles (light trucks, vans, multipurpose passenger vehicles) which are not required by FMVSS 205 to have 70% light transmittance in the backlite area. * The sunshade is not glazing material, nor is it in contact with glazing material. FMVSS 205 states that: "This standard specifies requirements for glazing materials for use in motor vehicles and motor vehicle equipment." * The rear window sunshade is fully analogous to conventional windshield sunvisors. In both cases, the driver-selectable device can be positioned in a way that reduces effective transmissibility below 70%, and then easily stowed when not needed to resto re full transmittance. * There is a well established international precedent for rear window sunshades. European and Japanese regulatory authorities have explicitly recognized and accepted these devices. General Motors is aware of previous Chief Counsel interpretations stating that the transmissibility requirements of FMVSS 205 must be met with a rear window sunscreen in position. (Reference Ms. Erika Jones letter to Mr. T. E. McConnell dated September 22, 1986, and Ms. Erika Jones letter to Ms. Susan B. House dated December 22, 1985.) We believe there is a critical distinction between the products the agency has previously commented on and the rear window sunshade GM contemplates. Specifically, the e arlier products were apparently tinting materials applied to the backlite, or shade devices that physically contacted the backlite via attaching hardware. By virtue of being in physical contact with the backlite, these earlier sunscreening products coul d be interpreted as being part of the backlite. The rear window sunshade GM plans to install will not be attached to the backlite in either the raised or stowed position, and therefore is clearly not part of the backlite glazing subject to FMVSS 205. We would appreciate a favorable response at the agency's earliest convenience. In order to accommodate our product plans for the sunshade device, we would like to obtain a response by July, 1995, if possible. If there is any additional information we ca n provide to help expedite the agency's review, please contact Mr. Philip Horton (810-947-1738), Mr. Richard Humphrey of our Washington office (775-5071), or me (810-947-0149). Thank you. |

ID: nht95-2.92OpenTYPE: INTERPRETATION-NHTSA DATE: May 22, 1995 FROM: Giuseppe Di Vito -- Societa Italiana Vetro S.p.A., Sede E Stabilimenti TO: Chief Counsel, NHTSA TITLE: Re: Request for legal interpretation, FMVSS 205. ATTACHMT: ATTACHED TO 8/4/95 LETTER FROM JOHN WOMACK TO GIUSEPPE DI VITO (A43; STD. 205; REDBOOK 2) TEXT: Dear Sir, INTRODUCTION Siv hereby request an interpretation for the testing of a Glass-Plastic glazing item 15A, FMVSS 205. We respectfully request the NHTSA's response at the soonest possible date. PURPOSE We ask by this letter for your interpretation involving testing of glazing item AS 15A, Glass Plastic (Annealed Glass-Plastic for use in all position in a Vehicle except for Windshield). We request an interpretation of whether or not test no.5 (bake ANSI Z.26.1-1977) may substitute test no. 4 (boil, ANSI Z26.1-1977) for certification of compliance of that glazing. BACKGROUND BMW requested our company to develop a security glazing made of: 1. Door glass: Glass - Polyurethane - Polycarbonate, as per enclosed sketch no. 1. 2. Rear Quarterlite: Glass - Polyvinylbutirale, as per enclosed sketch no. 2. Both these glass plastic parts have an internal safety spall shield to protect occupants against facial injuries coming form glass particles when the side window is broken or in case of accident. This product meets all the ECE R 43 compliance tests, whi ch include a 100 degrees C (212 degrees F) bake test. The product meets all the applicable test of FMVSS 205 except test n degrees 4 (boil test), which is not compatible with adhesion of the internal spall shield. This type of glazing will be installed on a limited number of 1996 BMW cars to be sold in Europe and USA. BMW and SIV believe that this spall shield is an important safety innovation, whose absence would not allow introduction of these side windows into the USA. We expect your urgent answer and thank you in advance. Attachment Bar graphs - security glazing (omitted). |

ID: nht95-2.94OpenTYPE: INTERPRETATION-NHTSA DATE: May 24, 1995 FROM: John Womack -- Acting Chief Counsel, NHTSA TO: Terry M. Habshey -- Oxytire Incorporated TITLE: NONE ATTACHMT: ATTACHED TO 3/6/95 LETTER FROM TERRY M. HABSHEY TO PHILIP RECHT (OCC 10785) TEXT: Dear Mr. Habshey: This responds to your March 6, 1995 letter to Philip Recht, our former Chief Counsel, and your telephone conversations with Walter Myers of my staff in which you requested a "new D.O.T. number." As discussed below, we are unable to provide you a tire man ufacturer's identification mark since the operations you perform on tires are not sufficient to make you the manufacturer of the tires. You explained that your company is a global exporter of tires, particularly to third world countries, but that you intend to distribute tires domestically in the future. You stated that you obtain new tires from different manufacturers consisting of ori ginal equipment overruns, blems, etc., and that by a new process you intend to remove "most" of the information from the tire sidewalls. The new process includes removing a thin layer of rubber from the tire sidewall, then vulcanizing a layer of new rubb er onto the sidewall. The new layer will contain a new "registered" trade name, logo, and "identifying marks along with the size, safety information, mounting instructions, maximum and minimum inflating instructions, etc." You emphasized that all tires will be new and meet "all minimum standards established by the Department of Transportation." Before addressing your request, let me first provide some background information. Chapter 301 of Title 49, U.S. Code (hereinafter Safety Act), authorizes the National Highway Traffic Safety Administration (NHTSA) to issue Federal motor vehicle safety st andards (FMVSS) applicable to new motor vehicles and new items of motor vehicle equipment sold in or imported into the United States. Tires are considered motor vehicle equipment. The Safety Act establishes a self-certification system in which manufact urers certify that their products comply with all applicable FMVSSs effective on the date of manufacture. In the case of tires, manufacturers reflect that certification by molding the letters "DOT" into or onto the sidewalls of all their tires manufactu red for sale in the United States. The FMVSSs are not applicable to tires intended solely for export, labeled for export on the tires and on the outside of the container, and exported. See 49 U.S.C. @ 30112(b)(3); 49 Code of Federal Regulations (CFR) 571.7(d)). Accordingly, you are free to export any tires you want, whether or not they comply with the FMVSSs and after whatever modifications you make to them. That is not the case, however, with tires distributed for sale in the United States. FMVSS No. 109, New pneumatic tires and FMVSS No. 110, Tire selection and rims, specify performance standards and labeling requirements for new passenger car tires and r ims. FMVSS No. 119, New pneumatic tires for vehicles other than passenger cars and FMVSS No. 120, Tire selection and rims for motor vehicles other than passenger cars, specify performance standards and labeling requirements applicable to tires and rims for vehicles other than passenger cars. 49 CFR Part 574, Tire identification and recordkeeping, requires new tire manufacturers to permanently mold into or onto one tire sidewall a tire identification number (TIN) and specifies methods by which new tire manufacturers and new tire brand name owners shall maintain records of tire purchasers. 49 CFR Part 575.104, Uniform tire quality grading standards (UTQGS), requires new motor vehicle and new tire manufacturers and brand name owners to provide informat ion to consumers concerning the relative performance of passenger car tires in the areas of treadwear, traction, and temperature resistance. The UTQGS grades are also required to be molded into or onto the tire sidewall. The labeling requirements specified in the regulations referred to above apply to the actual tire manufacturers and/or brand name owners, and the required information, including the DOT symbol and the TIN, must appear on all new tires before they can be sold to their first retail purchasers. A tire distributor or dealer cannot legally remove any of the required information from new tire sidewalls. The required information on new tires is intended for safety purposes, purchaser information, and to enab le this agency to identify the manufacturer in the event of a noncompliance or defect in a tire line or lot. A "manufacturer" is defined in 49 U.S.C. @ 30102(a)(5) as one who manufactures or assembles motor vehicles or equipment or one who imports motor vehicles or equipment for resale. The operations you describe would not be sufficient to make you the manufa cturer of the tires in question. According to your letter, you would, for marketing reasons, remove a thin layer of the surface area of the sidewalls of the tires so that most of the existing information is removed. You would then apply a new thin laye r of rubber containing new information. Your operations would thus not be changing the basic tire as such but simply changing the labeling. A change in labeling would not change who manufactured the tire. Thus, since you would not be a manufacturer of tires, you may not obtain a manufacturer's identification mark in accordance with 49 CFR @ 574.6. Only tire manufacturers or retreaders may obtain that mark. 49 U.S.C. @ 30122(b) prohibits manufacturers, distributors, dealers, and/or motor vehicle repair businesses from knowingly making inoperative any part of a device or element of design installed on or in a motor vehicle or item of equipment in compliance with applicable FMVSSs unless that individual reasonably believes that the vehicle or equipment will not be used when the device or element is inoperative. Thus, removal of the labeling information required to be marked on tire sidewalls in accordance w ith the standards and regulations discussed above could be a violation of @ 30122(b), which could subject the violator to civil penalties of up to $ 1000 per violation, or up to $ 800,000 for a series of related violations. In summary, the Safety Act does not apply to tires intended solely for export. Thus, those tires are not required to comply with any FMVSSs. However, all new or retreaded tires sold or imported into the United States for sale must comply with all applic able FMVSSs and regulations as discussed above. Distributors and dealers may not remove any of the labeling information required to be marked on new tires by the actual manufacturers and/or brand name owners of those tires. Removal of that information c ould make inoperative an element of design on those tires, which could constitute a violation of 49 U.S.C. @ 30122(b). I hope this information is helpful to you. Should you need additional information or have further questions, please feel free to contact Mr. Myers at this address or at (202) 366-2992. |

This pillow is designed specifically for use with booster car seats to provide support and comfort while the child is sleeping. Approximately one year ago, I spoke with you on the phone regarding Federal regulations governing the flame retardancy of the fabric used to manufacture our product. At that time, your response was that there are no codes to govern this accessory. We are now taking this product to the marketplace. Specifically, our local Wal-Mart store has purchased our pillow, however, we need to provide them with your response to us in writing. Would you please direct your reply to NiMi Manufacturing, Inc. so that we may provide retailers such as Wal-Mart with a copy. Their only concern was regarding the regulations of flame retardancy. I certainly appreciate the time you have taken to talk with me, and the cooperation you have shown. NiMi is a very, very small business. Needless to say, your help and expediency is greatly appreciated, especially now that a major retailer is carrying our product. Perhaps we won't be small too much longer! Please call me at (615) 636-5337 when you receive this. I'll be glad to answer any further questions you may have. Thanks again. Attachment Brochure omitted. |

ID: nht95-2.96OpenTYPE: INTERPRETATION-NHTSA DATE: May 25, 1995 FROM: John Womack -- Acting Chief Counsel, NHTSA TO: Stuart Sacks -- Tradepro, Inc. TITLE: NONE ATTACHMT: ATTACHED TO 1/25/95 LETTER FROM STUART SACKS TO PHILIP R. RECHT TEXT: Dear Mr. Sacks: This responds to your letter to Mr. Philip Recht, our former Chief Counsel, in which you stated that you are considering importing tires from the Hangzhou General Rubber Factory, which has been assigned NHTSA manufacturer identification number 7D. You s tated that the tires do not display the "molded D.O.T. code numbers," and that Federal motor vehicle safety standard (FMVSS) No. 119, New Pneumatic tires for motor vehicles other than passenger cars (49 CFR 571.119), "clearly does not require [DOT code n umbers] for non-passenger tires." Your reading of FMVSS No. 119 is not correct. I assume from your letter that you are considering importing only non-passenger car tires. This letter, then, will address only the labeling requirements for non-passenger car tires under FMVSS No. 119 and 49 CFR 574. I further assume that by "DOT code numbers" you mean the tire identification number (TIN) required by 49 CFR 574.5. 49 U.S. Code @ 30112 provides that no person may sell in or import into the United States any new motor vehicle or new item of motor vehicle equipment that does not comply with all applicable FMVSSs. With respect to non-passenger car tires, which are it ems of motor vehicle equipment, section S6.5 of FMVSS No. 119 requires specific items of information to be marked on the tire sidewalls. Those markings must be no less than 0.078 inch high and must be "raised above or sunk below the tire surface" a speci fied distance. Among other things, the markings must include the TIN (S6.5(b)). Paragraph S6.5(b) of FMVSS No. 119 requires the TIN to comply with part 574. Part 574.5 requires that the TIN be permanently molded into or onto tire sidewalls as specified in Figure 1 of Part 574, and specifies what information the TIN must contain. Th e TIN can be branded into or onto the sidewalls of retreaded tires after the fact, but not new tires. On new tires, the TIN must be molded into or onto the tire sidewalls by the original manufacturer. I hope this information is helpful to you. Should you have any further questions or need additional information, please feel free to contact Walter Myers of my staff at this address or at (202) 366-2992. |

Of course the Retention Test is for the straps that hold the helmet on the head. I c annot find any specifications as to what kind or how much material is to be used in the manufacturing of said helmets. Also, there is no specific language to the effect the helmet may not be covered with materials such as wigs, caps, cloth, etc. Theref ore, would you please clarify the following points for me: 1. Is the Penetration Test (S7.2) for testing the penetration of the outer shell? 2. Is the Impact Attenuation Test (S7.14) for testing types of impact material to prevent head injuries? 3. Is the Retention Test (S7.3) for testing straps that retain the brim of the helmet onto the head? 4. Are there any specifications in FMVSS218 as to what type and how much material can be used in the manufacturing of helmets? 5. Are there any stipulations in FMVSS218 that you cannot decorate a helmet with any material (leather, cloth), wigs, flowers, decals, hats, etc.? I look forward to your reply; thank you for your assistance in this matter. |
