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: aiam4457OpenMartin Chauvin Chief, Carrier Safety Bureau State of New York Department of Transportation Albany, NY 12232; Martin Chauvin Chief Carrier Safety Bureau State of New York Department of Transportation Albany NY 12232; "Dear Mr. Chauvin: This is a response to your letter of last year wher you asked us to address a statement allegedly made by an unidentified school bus manufacturer that a school bus driver's seat equipped with an upper torso restraint or shoulder harness violates 'head impact protection' requirements contained in the Federal Motor Vehicle Safety Standards. I apologize for the delay in this response. Nothing in our Federal standards prohibits a manufacturer from installing a seat belt assembly that includes a lap belt and upper torso restraint at the driver's seat of a school bus. Standard 208, Occupant Crash Protection, specifies occupant protection requirements for the driver's seat of all buses. Section S4.4 of that standard gives a manufacturer the choice of equipping a bus driver's seat either with a complete automatic restraint system, a Type 1 seat belt assembly (which consists of a lap belt), or a Type 2 seat belt assembly (which consists of a lap and shoulder belt). There are no 'head impact protection' requirements in Standard No. 208 for the driver's seating position in a bus. Thus, the driver's seat of all buses may be equipped with a lap and shoulder belt if the manufacturer chooses to do so. Standard 222, School Bus Passenger Seating and Crash Protection, sets forth additional requirements for occupant crash protection for school buses. Section S5.3 of Standard 222 refers to a 'head protection zone,' and establishes head impact requirements within the head protection zones. However, the head protection zones are established with respect to passenger seats in the school bus. Standard 222 does not contain any head impact protection requirements for the driver's seat in school buses. I hope you find this information helpful. Sincerely, Erika Z. Jones Chief Counsel"; |

Trantham - General Manager Armstrong Ford Estate Golden Rock P.O. Box 339 Christiansted St. Croix United States Virgin Islands; Dear Mr. Trantham: This is in response to your letter of October 7, 1980, requestin information on the Federal odometer disclosure requirements.; The National Highway Traffic Safety Adminstration does not print form for the disclosure of odometer information. In states that are using their titles in lieu of the separate Federal form, the states provide the forms. In other states dealers generally have their own forms printed and individuals either use a dealer's form or simply write out the information on a sheet of paper.; I have enclosed a copy of the Federal regulations detailing the Federa odometer disclosure requirements. You may adopt that format or alter it to meet your specific needs as long as all of the information in it is included.; If you have any further questions, please do not hesitate to write. Sincerely, Shirley Ransom, Trial Attorney |

ID: aiam3238OpenMr. William N. Whitley, Vice President, Whitley & Whitley, Inc., 20600 Chagrin Boulevard, Tower East, Shaker Heights, Ohio 44122; Mr. William N. Whitley Vice President Whitley & Whitley Inc. 20600 Chagrin Boulevard Tower East Shaker Heights Ohio 44122; Dear Mr. Whitley: This responds to your February 8, 1980, letter asking whether th CarVan that you manufacture would be required to comply with Federal safety standards. The CarVan is designed to be mounted over the trunk of a car and weight approximately 80 pounds.; The CarVan is considered a piece of motor vehicle equipment fo purposes of compliance with the motor vehicle safety standards. Since it does not slide into the cargo area of a truck, however, it would not be considered a slide-in camper subject to Standard No. 126, Truck-Camper Loading. However, as a piece of equipment, it would be required to comply with Standard No. 205, *Glazing Materials*. I am enclosing an information sheet detailing where you can obtain a complete copy of all motor vehicle safety standards.; The agency notes that the CarVan would be installed in such a locatio that it would obscure the rear lights of the vehicle upon which it is mounted. The agency considers this to be very dangerous and concludes that you should adopt a tail light system for the CarVan. The Federal safety standard for lighting is Standard No. 108. Without a tail light system, the agency concludes that the installation and use of your CarVan would constitute a safety related defect, and we would exercise our authority to require any such defect to be remedied. We also note also that many States prohibit any device that covers the licence plates.; The agency would like to take this opportunity to correct som misinformation that was supplied to you an May 4, 1978, when we responded to your previous request for information on a camper that was designed to be loaded in a car's trunk.; In that letter, the agency stated that the camper would be required t comply with Standard No. 126. That statement is incorrect. Since your camper is designed for a passenger car and not a truck, it would not be required to comply with Standard No. 126. It would be subject to the other standard mentioned above for the CarVan. We regret any inconvenience our error may have caused you.; Sincerely, Frank Berndt, Chief Counsel |

ID: aiam4007OpenMr. Fernando Benabbi, Ditta Alice, Via Trieste 18, 20146 Milano, Italy; Mr. Fernando Benabbi Ditta Alice Via Trieste 18 20146 Milano Italy; Dear Mr. Benabbi: Thank you for your letter of June 3, 1985, asking about compliance o the child seat, 'Titti,' manufactured by Bizzi in Milan, with Federal Motor Vehicle Safety Standard No. 213, *Child Restraint Systems*. You state in your letter that you plan to export these child seats to the United States.; This agency administers the National Traffic and Motor Vehicle Safet Act of 1966, as amended, 15 U.S.C. 1391, *et seq*. (the Act). Unlike the type-approved or homologation process used in Europe, we have a self-certification process in the United States. Under the Act, manufacturers are responsible for certifying that items of motor vehicle equipment, such as child seats, which are made by them, comply with the requirements of any applicable safety standard. For this reason, the agency does not approve equipment items prior to their sale.; Each child restraint system, such as the 'Titti' child seat, must b labeled and certified according to the requirements of S5.5 of Standard No. 213. The label which you enclosed does not state, as required by S5.5, that 'THIS CHILD RESTRAINT SYSTEM CONFORMS TO ALL APPLICABLE FEDERAL MOTOR VEHICLE SAFETY STANDARDS.' The label should be changed to meet the requirements of S5.5. If the manufacturer chooses, he may, but is not required to, certify that the child restraint also complies with the provisions of section S8 and state on the label: 'THIS RESTRAINT IS CERTIFIED FOR USE IN MOTOR VEHICLES AND AIRCRAFT.'; In your letter and on the label you enclosed there is the followin reference: 'ATG CALSPAN No. 7174-1.' This may refer to a contract between the manufacturer, Bizzi, and Calspan to test the child restraint for compliance with Standard No. 213. You can write to Calspan to inquire about any testing at the following address:; >>>Ms. Barbara Kelleher, Arvin-Calspan, Inc., Advanced Technolog Center, 4455 Genesee Street, Buffalo, New York 14225<<<; Please note that Calspan's test may not cover requirements of Standar No. 213 regarding webbing abrasion, flammability, or hardware corrosion, for example. Testing by Calspan or any other testing laboratory does not relieve the manufacturer from its responsibility of certifying the equipment item.; Under the Vehicle Safety Act and our regulations, manufacturers hav the responsibility to conduct notification and remedy campaigns for safety related defects or noncompliances in their products (VSA SS151-159). The Vehicle Safety Act defines a manufacturer as; >>>any person engaging in the manufacturing or assemblying (sic) o motor vehicles or motor vehicle equipment, including any person importing motor vehicles or motor vehicle equipment for resale.<<<; In the event that neither the importer nor the actual manufacturer me an obligation imposed on a 'manufacturer' by the Act or our regulations, the agency would consider taking enforcement action against both parties. Any such obligation, however, may be satisfied by either party.; In addition, there are two other regulations which affec manufacturers. Those regulations require manufacturers to provide the agency with certain identifying information (49 CFR Part 566), and, in the case of foreign manufacturers, to designate an agent for the service of process (49 CFR Part 551).; A copy of Standard No. 213, the Vehicle Safety Act, Part 566, Part 551 and an instruction sheet for new manufacturers is enclosed.; I hope this information is helpful to you. Sincerely, Jeffrey R. Miller, Chief Counsel |

ID: aiam4729OpenMr. Kenneth E. Tompor Auto Brokers & Leasing LTd. 4140 S. Lapeer Road (M24) Pontiac, MI 48057; Mr. Kenneth E. Tompor Auto Brokers & Leasing LTd. 4140 S. Lapeer Road (M24) Pontiac MI 48057; "FAX: 313-373-0565 Dear Mr. Tompor: This is in reply to your FAX o April 26, l990. You would like a statement from this agency, for purposes of litigation that commences on May 1, that a l985 Ferrari 288 GTO cannot be legally imported into the United States. Pursuant to amendments made to the National Traffic and Motor Vehicle Safety Act (15 U.S.C. 1381 et seq.) by P.L. 100-562, the Imported Vehicle Safety Compliance Act of l988, a motor vehicle not originally manufactured to conform to the Federal motor vehicle safety standards, cannot, subject to the exception noted below, be imported permanently into the United States on and after January 31, l990, unless the Administrator of the National Highway Traffic Safety Administration has determined that it is capable of being readily modified to conform to all applicable Federal motor vehicle safety standards, or that its safety features comply with or are capable of being modified to comply with all such applicable standards. The Administrator has made no determination with respect to the l985 Ferrari 288 GTO. However, no such determination is necessary if the following criteria are met at the time of importation. The importer's assigned place of employment was outside the United States as of October 31, l988, and (s)he has not had an assigned place of employment between that time and the entry of the motor vehicle. The importer has not previously imported a motor vehicle into the United States before October 31, l988, that was not in compliance with all applicable Federal motor vehicle safety standards. The importer had acquired (or had entered into a binding contract to acquire) the motor vehicle before October 31, l988. The vehicle must be entered not later than October 31, l992. Only if an importer meets these criteria may (s)he at the present time legally import a nonconforming l985 Ferrari 288 GTO into the United States (subject, of course, to the obligation to bring it into compliance with the safety standards after its entry). Sincerely, Stephen P. Wood Acting Chief Counsel"; |

ID: aiam3516OpenMr. Thomas D. Turner, Blue Bird Body Company, P.O. Box 937, Fort Valley, GA 31030; Mr. Thomas D. Turner Blue Bird Body Company P.O. Box 937 Fort Valley GA 31030; Dear Mr. Turner: This responds to your letter of October 26, 1981, requesting severa interpretations of the requirements of Standard No. 201, *Occupant Protection in Interior Impact*. The answer to each of your questions is discussed below.; Your first question concerned section 3.3 of the standard, which amon other things, requires that an 'interior compartment door assembly located in...a side panel adjacent to a designated seating position...' must remain closed when tested under certain conditions. You stated your belief that the requirement only applies to interior compartment doors located within the head impact area, defined in Part 571.3 of Title 49. You asked if the area adjacent to a designated seating position is to be determined by projecting laterally from the head impact area for a designated seating position to the side panel next to it.; The impact protection requirement for interior compartment doors wa added to the standard on October 25, 1968 (33 FR 15794). As explained in that notice, a copy of which is enclosed, the agency specifically denied requests to limit the interior compartment door requirement to doors located in the head impact area. The requirement is designed to provide protection to the head and other portions of an occupant's body that can be thrown against an interior compartment door opened by inertial forces in a crash. To accomplish the purpose of the standard, any interior compartment door, defined in Part 571.3 of Title 49, that is located in a side panel and is next to a designated seating position is covered by the requirements of section 3.3 of the standard.; You also asked how the term 'instrument panel' is defined for th purposes of section 3.3 of the standard. You are correct that the term refers to the panel below the windshield which is used to mount the speedometer, other gauges, etc. For the reasons discussed in response to your first question concerning S3.3, any interior compartment door on the instrument panel is covered by the requirements of section 3.3, not just those located in the head impact area.; You also asked about the requirements of section 3.3.1 of the standard You state that section 3.3.1 allows the use of either option (b) or (c) to show compliance. Your statement is not correct. Section 3.3 of the standard requires more than compliance with either option (b) or (c) of section 3.3.1. Section 3.3 requires interior compartment doors to remain closed when 'tested in accordance with either S3.3.1(a) and S3.3.1(b) or S3.3.1(a) and S3.3.1(c).'; You also state that you interpret option (c) of section 3.3.1 to be horizontal inertial load of 30g in a longitudinal direction which would simulate a forward 30 mile per hour flat barrier impact. Your interpretation is correct. Section 3.3.1(c) provides that an interior compartment door latch must be subject to 'a horizontal inertia load of 30g in a longitudinal direction in accordance with the procedures described in section 5 of SAE Recommended Practice J839b, 'Passenger Car Side Door Latch Systems,' or an approved equivalent.' The purpose of the requirement is to impose loads similar to the loads experienced by a door latch tested in the 30 mile per hour forward barrier crash required by section 3.3.1(b) of the standard.; You further state that the loading applied in accordance with sectio 3.3.1(c) should be a forward deceleration inertia loading. Your interpretation is not correct. To ensure that the requirements of sections 3.3.1(b) and 3.3.1(c) are equivalent in stringency, the agency believes that the 30g inertia load requirement of section 3.3.1(c) must take into account the distortion and deformation that would occur in a 30 mile per hour barrier impact. Therefore, the 30g inertia load must be applied in both the forward and rearward direction. Likewise, the 10g inertia load requirement of section 3.3.1(a) must be applied in both the inboard and outboard direction.; Your final question concerned the requirements of section 3.5.1 of th standard, which specifies that armrests must comply with at least one of three options. Section 3.5.1(c) specifies that one option is providing an armrest which has 'Along not less than 2 continuous inches of its length...when measured vertically in side elevation... at least 2 inches of coverage within the pelvic impact area.' You are correct that an armrest complying with section S.3.5.1(c) can be made of any material, as long as it meets the dimensional requirements set by that section.; If you have any further questions, please let me know. Sincerely, Frank Berndt, Chief Counsel |

ID: aiam4379OpenMr. Walter Mayr, The Austrian Trade Commission, 1875 Connecticut Avenue, N.W., Suite 1114, Washington, DC 20009; Mr. Walter Mayr The Austrian Trade Commission 1875 Connecticut Avenue N.W. Suite 1114 Washington DC 20009; Dear Mr. Mayr: This responds to your August 5, 1987 letter to my office and August 1 telephone conversation between Ms. Schott of your staff and Ms. Hom of mine, concerning our regulations for motor vehicles. You enclosed a brochure from the Austrian firm, Reformwerke Wels, describing a 'public utility vehicle.' Subsequently, Ms. Schott indicated in her telephone call that Reformwerke Wels has informed her that the vehicles in question have a top speed of 15.53 miles per hour (mph). Based on this information, you asked whether the vehicle is a 'motor vehicle' for the purposes of our regulations. The answer is no.; Under a longstanding policy, the National Highway Traffic Safet Administration has regarded vehicles *not* to be 'motor vehicles' within the meaning of the National Traffic and Motor Vehicle Safety Act, and therefore not subject to our motor vehicle safety standards, if they (1) have an unusual body configuration which sets the vehicles apart form typical highway traffic, and (2) have a maximum attainable speed of 20 mph or less. The utility vehicles manufactured by Reformwerke Wels meet these criteria. Thus, the vehicles are not 'motor vehicles' under our regulations and the manufacture of those vehicles is not regulated by this agency.; You might wish to contact the Consumer Product Safety Commission t learn if they have any Federal safety regulations applicable to the type of utility vehicle manufactured by Reformwerke Wels. Their address is: Office of the General Counsel, U.S. Consumer Product Safety Commission, 1111 18th Street, N.W., Washington, DC 20207. Telephone: (202) 492-6980.; Please contact us if we can be of further assistance. Sincerely, Erika Z. Jones, Chief Counsel |

ID: aiam1481OpenMr. William J. Cicero, Supt. of Maintenance, Triboro Coach Corporation, 85-01 24th Avenue, Jackson Heights, NY 11369; Mr. William J. Cicero Supt. of Maintenance Triboro Coach Corporation 85-01 24th Avenue Jackson Heights NY 11369; Dear Mr. Cicero: This is in reply to your letter of April 4, 1974, concerning you request for an exemption from the roof emergency exit requirements (S5.2.1) of Motor Vehicle Safety Standard No. 217 (49 CFR 571.217). We had denied an earlier request on March 27, 1974 following your letter to us of February 13, 1974.; We must again deny your request. The Federal motor vehicle safet standards which apply to motor vehicles (some apply to equipment only) specify safety requirements which apply to vehicle types generally (passenger cars, trucks, buses, etc.) and must of necessity be based on the use to which such vehicle types are generally put. The NHTSA has determined through the administrative rulemaking process that buses, including buses for use in urban environments, must have a roof emergency exit when a rear exit can not be installed due to the configuration of the bus. In most cases, including many urban situations, the roof exit can be an important safety feature, particularly when the bus is overturned on a side. While we do not dispute the facts you present, we view the situation as unusual, and not a suitable basis for modifying a requirement applicable to every urban bus. Our regulations do not permit exemptions from requirements for buses sold to one party.; However, under the National Traffic and Motor Vehicle Safety Act (1 U.S.C. SS1391 *et seq.*) under which Standard No. 217 is issued, a vehicle need not conform to a Federal motor vehicle safety standard after its sale to its ultimate user. Consequently there is no Federal prohibition to your modifying or eliminating the roof exits in these buses if you wish, after you receive them from the manufacturer.; Sincerely, Robert L. Carter, Associate Administrator, Motor Vehicl Programs; |

ID: aiam3146OpenMr. Robert C. Schultz, 5115 N. Mulligan, Chicago, IL 60630; Mr. Robert C. Schultz 5115 N. Mulligan Chicago IL 60630; Dear Mr. Schultz: This is in response to your letter to the Secretary of Transportatio regarding the transportation of diesel fuel in the trunk of an automobile in plastic auxiliary tanks. You asked whether it is permissible to permanently install a plastic auxiliary diesel fuel tank in the trunk of a four door passenger car. You also noted the availability of 5.5 gallon plastic utility containers that can be used as auxiliary tanks. From your description I gather that these types of containers are not attached to the vehicle's fuel system.; From your letter I got the impression that you are asking whether an law administered by this agency would prohibit an individual from using either of these types of tanks in his private automobile. With respect to small tanks that are not connected to the automobile's fuel system, this agency administers no law that would prevent an individual from carrying such a tank in his automobile. However, please note that this is a very dangerous practice that can lead to fires and explosions potentially harmful or fatal not only to the driver and passengers of the vehicle carrying such a tank but also occupants of other nearby vehicles. I have enclosed a copy of a press release that the Department of Transportation issued this Spring, which describes the dangers associated with carrying gasoline, but which is also applicable to carrying diesel fuel. As noted in the press release this agency strongly discourages the use of portable fuel containers.; There is no law administered by this agency which would bar a individual from installing a plastic auxiliary fuel tank in his or her own automobile or from using such a tank once installed by the individual of by a commercial installer. However, there are legal obligations imposed by the statutes and regulations under which we operate that would apply to the manufacturers and installers of such tanks. Since I am unsure as the exact scope of your inquiry I will summarize these below.; The National Traffic and Motor Vehicle Safety Act, as amended 1974 (the Act) authorizes the National Highway Traffic Safety Administration (NHTSA) to issue motor vehicle safety standards applicable either to entire vehicles or to equipment for installation in vehicles. Safety Standard No. 301-75, *Fuel System Integrity*, is a vehicle standard which applies to certain vehicles, including passenger cars, that use fuel with a boiling point above 32 degrees F. Under the standard's requirements, no part of a vehicle's entire fuel system can have fuel spillage beyond certain specified amounts during barrier crash tests. Specific performance requirements for individual components of the fuel system, such as the fuel tank, are not currently included in the standard. With the advent of high density polyethylene (plastic) fuel tanks, however, the current 'system' performance requirements might not be sufficient to ensure the integrity of vehicle fuel systems. For this reason, the agency has published an Advance Notice of Proposed Rulemaking concerning the advisability of establishing performance standards for plastic tanks (44 FR 33441, June 11, 1979, copy enclosed).; Despite the inapplicability of Safety Standard No. 301-75 to thei manufacture, auxiliary fuel tanks must be designed and manufactured for safety. A manufacturer of auxiliary fuel tanks, is subject to the defects responsibility provisions of the Act (sections 151 *et seq*.). Upon discovery of a safety-related defect by the Secretary of Transportation, the NHTSA Administrator, or the manufacturer itself, the manufacturer would be required to notify vehicle owners, purchasers, and dealers and remedy the defect.; If a manufacturer, distributor, dealer, or motor vehicle repai business installed an auxiliary fuel tank in a new vehicle, prior to its first purchase in good faith for purposes other than resale, that person or entity would be a vehicle alterer under NHTSA regulations. As an alterer, that person or entity would be required by 49 CFR 567.7 to affix an additional label to the vehicle stating that, as altered, the vehicle conforms to all applicable Federal motor vehicle safety standards--including Safety Standard No. 301-75. Should a noncompliance or safety- related defect be discovered in such a vehicle, as a result of the modification, the alterer would be required to notify vehicle owners, purchasers, and dealers and to remedy the defect.; If a manufacturer, distributor, dealer, or motor vehicle repai business installed an auxiliary gasoline tank in a used passenger vehicle, that person or entity would not be required to attach an alterer's label. However, section 108(a)(2)(A) of the Act would apply. Section 108(a)(2)(A) provides in relevant part that:; >>>No manufacturer, distributor, dealer, or motor vehicle repai business shall knowingly render inoperative, in whole or part, 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 . . .<<<; Thus, if one of the named entities added an auxiliary tank to a use passenger vehicle manufactured in compliance with Safety Standard No. 301-75 and other standards, and in the process knowingly rendered inoperative the compliance of the fuel system or another system, that person or entity would be in violation of section 108(a)(2)(A).; I hope that you will find this response helpful and have not bee inconvenienced by our delay in sending it to you. If you have any further questions please feel free to address them to Ms. Debra Weiner of my office (202-426-2992).; Sincerely, Frank Berndt, Chief Counsel |
