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.

Blakenship Director of CentiMile Programs Long Mile Rubber Company 155 South Court - Exchange Park P.O. Box 45228 Dallas Texas 75235; Dear Mr. Blakenship: This is in reply to your letter to Mr. Van Orden dated May 20, 1971. Tires retreaded prior to the effective date of the retreaded standar (January 1, 1972) are not permitted to contain the DOT symbol on the tire. If you have marked your matrices with the symbol, I suggest you buff the letters off the tire after it is retreaded, or remove the symbol from the matrix, or fill in that portion of the matrix.; The retreading of tires without the DOT markings before the effectiv date of the standard is permissible.; Sincerely, Lawrence R.

Pratte Manager Materials Engineering Pullman Trailmobile 200 East Randolph Drive Chicago IL 60601; Dear Mr. Pratte: This responds to Trailmobile's March 4, 1976, letter asking if trailer equipped with one or more axles that have a gross axle weight rating (GAWR) of 24,000 pounds or more is excluded from the requirements of Standard No. 121, *Air Brake Systems*.; Section S3. of Standard No. 121 provides in part that any vehicl manufactured before September 1, 1977, that has a GAWR for any axle of 24,000 pounds or more is excluded from the standard. The determination of GAWR is made by the vehicle manufacturer (49 CFR 571.3) and must be based on the capabilities of the axle system at 60 mph. Because the determination is made by the vehicle manufacturer, the NHTSA is unable to say that the components you mention in your letter would necessarily constitute an axle system with a GAWR of 24,000 pounds.; Yours truly, Frank Berndt, Acting Chief Counsel |

ID: aiam5077OpenMrs. Edna Sutlief Project Concern 504 Kansas Ave. Atchison, KS 66002; Mrs. Edna Sutlief Project Concern 504 Kansas Ave. Atchison KS 66002; "Dear Mrs. Sutlief: This responds to your request to the NHTSA's Aut Safety Hotline for information on Federal regulations concerning safety belts and tiedowns for vans used for transporting disabled and senior citizens. Your specific concerns relate to whether Federal law mandates safety belt use in these vans. I am pleased to have this opportunity to explain our laws and regulations to you. Federal laws administered by this agency regulate the manufacture and sale of new vehicles. It leaves the individual States free to address questions about the registration and operation of vehicles within their borders. Questions about whether persons are required to use their safety belts while riding in a motor vehicle relate to the operation of a vehicle, and are thus addressed by the individual States, not the Federal government. Accordingly, your question about whether passengers riding in your vans must use their safety belts is one that should be addressed to the State of Kansas. I note, however, that while the Federal government leaves these questions of requirements in this area to the individual States, this agency strongly encourages the use of safety belts by all persons in a vehicle every time they ride in a vehicle. In addition, if your organization is subject to the requirements of the Americans with Disabilities Act, regulations implementing that Act require installation of wheelchair securement devices and passenger seat belts and shoulder harnesses. For further information concerning the regulations implementing the Americans with Disabilities Act you should contact: Robert C. Ashby, C-50, Office of the General Counsel, Department of Transportation, 400 Seventh St. SW, Washington, DC 20590. It might be helpful for me to set out the Federal requirements for new motor vehicles. A provision of Federal law, the National Traffic and Motor Vehicle Safety Act (the Safety Act), authorizes this agency to issue Federal Motor Vehicle Safety Standards, which set performance requirements for new motor vehicles and items of motor vehicle equipment. It is a violation of Federal law for any person to manufacture or sell any new vehicle or item of motor vehicle equipment that does not comply with all applicable safety standards. Standard No. 208, Occupant Crash Protection, requires safety belts to be installed at 'designated seating positions.' The specified requirements for belt installation vary, depending on the particular vehicle type and seating position within the vehicle. However, Standard No. 208 would not require installation of a safety belt at a wheelchair securement location, because such a location would not be a 'designated seating position,' as that term is defined in 49 CFR 571.3. Furthermore, none of the other Federal motor vehicle safety standards require installation of, or set forth performance requirements for, wheelchair securement devices. If a safety belt is installed at a wheelchair securement location, either voluntarilly or pursuant to another state or federal requirement, the safety belt must comply with the requirements of Standard No. 209, Seat Belt Assemblies. Standard No. 209 sets forth strength, elongation, webbing width, durability, and other requirements for seat belt assemblies as separate items of motor vehicle equipment. The Safety Act also requires that manufacturers of 'motor vehicle equipment' notify purchasers and repair at no cost to the purchasers equipment that is determined to contain a defect related to motor vehicle safety. Wheelchair securement devices are items of 'motor vehicle equipment' within the meaning of the Safety Act. Hence, manufacturers of wheelchair securement devices are obliged to notify and remedy without charge any defects related to motor vehicle safety that occur in their products. You may also be interested to learn that this agency currently has a rulemaking pending to set forth performance requirements for wheelchair securement devices. While this proposal relates only to wheelchair securement devices installed in school buses, I am enclosing a copy of the notice of proposed rulemaking for your information. I hope you find this information helpful. If you have any other questions, please contact Mary Versailles of my staff at this address or by phone at (202) 366-2992. Sincerely, Paul Jackson Rice Chief Counsel Enclosure"; |

Nodar Vice President and General Manager Engine Division McCulloch Corporation P.O. Box 92180 Los Angeles j California 90009"; Dear Mr. Nodar: This is in reply to your letter of March 28, 1979, asking for a interpretation of Federal Motor Vehicle Safety Standard No. 123 as it relates to a manual fuel shut off control design that McCulloch Corporation wishes to incorporate in a future model.; Table 1 of Standard No. 123 specified the following operating position for a manual fuel shut off control: 'Off' - control forward, 'On' - control downward, and 'Reserve' (if provided) - control upward. The control that McCulloch would like to provide is a simple on-off knob control that in plan view is perpendicular to the ground and operates from on to off when a seated operator rotates it to the right, or counter-clockwise, direction. The control would be identified by the words 'Fuel off' and an arrow pointing to the right.; In our opinion, the McCulloch control does not comply with Standard No 123. The safety rationale for NHTSA's operating position is expressed in the response to petitions for reconsideration of the rulemaking action that adopted it:; >>>'The NHTSA has determined that the control should be standardized b requiring its operation along a longitudinal rather than a transverse axis. In this location there is a greater likelihood that in the event of a crash the control will be carried by inertia to the off position, thereby shutting off the fuel' (37 FR 17474, Aug. 29. 1972).<<<; The McCulloch control possesses neither the control positions no identification specified by Standard No. 123, nor does it appear that, in a crash, inertia would carry it to an off position.; Sincerely, Frank Berndt, Acting Chief Counsel |

ID: aiam1034OpenMr. Robert E. Bauer, Harnischfeger Corporation, 4400 West National Avenue, Milwaukee, WI 52346; Mr. Robert E. Bauer Harnischfeger Corporation 4400 West National Avenue Milwaukee WI 52346; Dear Mr. Bauer: This is in reply to your letter of January 25, 1973, to Gordo Lindquist, Regional Administrator, NHTSA, asking whether Federal standards require the installation of seat belts on certain vehicles you manufacture. According to brochures you have submitted, these vehicles are your RH 25 3-cu. yd. heavy duty hydraulic shovel, R-150-1 15-ton hydraulic crane, W-350 35-ton hydraulic swinger crane, and T-150 15-ton fully hydraulic truck crane.; With reference to the first three vehicles, the RH 25, R-150-1 an W-350, the NHTSA does not consider these vehicles to be manufactured primarily for use on the public roads. Therefore, they are not 'motor vehicles' subject to regulation under the National Traffic and Motor Vehicle Safety Act of 1966. We view them as construction equipment whose use of the public roads is incidental to their primary work-performing purpose.; THe NHTSA believes, however, based on the information you hav submitted, that the T-150 hydraulic truck crane is a motor vehicle under the Safety Act, and a 'truck' under the motor vehicle safety standards. We base this determination on the vehicle's speed capability, that its manufacturer classifies it as a 'truck crane', and that its overall appearance appears to be that of a vehicle designed to be used on the highway. As a truck, the vehicle is required to be equipped with seat belts as specified in Motor Vehicle Safety Standard No. 208, Occupant Crash Protection (49 CFR 571.208, copy enclosed). It is required also to conform to safety requirements specified in other safety standards and regulations. Copies of the standards can be obtained as described in the enclosed, 'Where to obtain Motor Vehicle Safety Standards and Regulations'.; Our decision as to whether this vehicle is a motor vehicle is base only on that information which you have provided us. Other relevant factors which can be taken into consideration are set forth in the enclosed interpretation regarding mini- bikes. If you have further information which you believe we should also consider we will be glad to review it.; Sincerely, Lawrence R. Schneider, Chief Counsel |

ID: aiam4236OpenMs. Robin Leeds, Executive Director, Connecticut Operators of School Transportation Association, 133 Jerome Avenue, Burlington, CT 06013; Ms. Robin Leeds Executive Director Connecticut Operators of School Transportation Association 133 Jerome Avenue Burlington CT 06013; Dear Ms. Leeds: This responds to your letter concerning the height of front bumpers o school buses. According to your letter, school bus regulations for the state of Connecticut require front bumpers on all school buses to be located 18 inches from the ground. Since the bumpers on standard chassis are placed several inches higher than this, your bus body dealers must remove the bumpers and reposition them, add an additional piece to the existing bumper to make the bottom edge lower, or use an alternate bumper. I regret the delay in answering your letter.; You are interested in a revision to Connecticut's requirements fo school bus bumpers, which would require a bumper height that corresponds to the height used by chassis manufacturers, thereby avoiding the need to reposition or replace original bumpers. However, the state Department of Motor Vehicles believes that the 18 inch height, corresponding to the height of a passenger car bumper, is safer since it prevents the override of an automobile. You asked three questions related to this issue, which I have addressed below.; I would like to begin with some background information on our bumpe standard. The National Highway Traffic Safety Administration (NHTSA) issued its Part 581 Bumper Standard pursuant to the Motor Vehicle Information and Cost Savings Act (the Cost Savings Act) and the National Traffic and Motor Vehicle Safety Act (the Vehicle Safety Act). The standard establishes requirements for impact resistance in low-speed front and rear collisions and includes a bumper height requirement. The bumper height requirement prevents override in collisions with other vehicles subject to the standard.; The standard applies to 'passenger motor vehicles other tha multipurpose passenger vehicles.' The term 'passenger motor vehicles other than multipurpose passenger vehicles' generally corresponds to passenger cars. Title I of the Cost Savings Act specifically excludes trucks and larger buses from any bumper standards and allows multipurpose passenger vehicles (MPV's) to be exempted from the bumper standard. I believe you are interested in the large, standard school buses to which the standard does not apply.; You first asked whether it would be safer if school bus bumpers wer kept at the position originally utilized by the chassis manufacturer. We are not aware at this time of any indications that it is safer to retain the bumper in its original position. However, NHTSA does not have sufficient data at this time to evaluate the safety effects of lowering the bumper. Chassis manufacturers may have considered practical reasons for positioning their bumpers in the manner they have done, since trucks and buses sometimes require greater ground clearance than passenger cars to negotiate ramps and to clear obstacles associated with off-road operation.; Your second question asked whether repositioning or replacing th bumper would affect compliance of the school bus with our motor vehicle safety standards. As you might know, persons altering a new vehicle prior to its first sale are considered vehicle alterers under NHTSA's certification regulation. Part 567.7 *Requirements for Persons who Alter Certified Vehicles*, requires alterers to certify that the vehicle, as altered, complies with all applicable safety standards.; A dealer that modified the bumper of a school bus, prior to its firs sale, would thus be required to certify that the school bus, as altered, complies with all applicable safety standards. A violation of the Vehicle Safety Act would occur if an alterer modified the school bus in such a way that the vehicle no longer complied with an applicable standard. Since the school bus's continued compliance with applicable safety standards depends on many factors, such as the design of the school bus and the nature of work performed on the vehicle, dealers modifying school bus bumpers might want to contact the vehicle manufacturer to learn if any standards might be affected by the lowering of the bumper and obtain any information needed to make the required certification.; Your third question asked 'What, if any, liability is incurred by dealer who removes the original bumper and repositions or replaces it? And if there is an implied liability, how can the dealer protect himself?' Violations of Vehicle Safety Act provisions are punishable by civil fines of up to $1000 per violation, with a maximum fine of $800,000 for a related series of violations. A dealer altering a school bus can protect itself from such liability by ensuring that it complies with all relevant Federal requirements.; The issue of possible liability in tort is a matter of state law rathe than Federal law. Therefore, we suggest that you consult a local attorney on this question.; I hope this information is helpful. Please contact my office if yo have further questions.; Sincerely, Erika Z. Jones, Chief Counsel |

ID: aiam1464OpenMr. R. Debesson, General Secretary, European Tyre and Rim Technical Organisation, Avenue Brugmann, 32, 1060 Bruxelles, BELGIUM; Mr. R. Debesson General Secretary European Tyre and Rim Technical Organisation Avenue Brugmann 32 1060 Bruxelles BELGIUM; Dear Mr. Debesson: This is in reply to your Submission Nos. 78 and 79, of February 1 1974, and February 19, 1974, respectively. In Submission No. 79 you request that several corrections be made to the Tables of the Appendices of Standard Nos. 109 and 110 as they appeared in the *Federal Register* on November 1, 1973 (38 FR 30234). In Submission No. 78 you request new additions to the Tables.; You request in Submission No. 79 that Footnote No. 1 of Table I-S an I-T in standard No. 109 be corrected. A correction of those footnotes was published in the *Federal Register* on February 5, 1974 (39 FR 4578), and we enclose a copy. You also request that in Table I-C of Standard No. 109 the test rim width for the 165-15 tire size designation be changed to 4 1/2 inches. That correction was published in the *Federal Register* of November 13, 1973 (38 FR 31309), copy also enclosed.; You further request that Table I-D be corrected by changing the tes rim width of the 145-10 tire size designation to 4 1/2 inches, by changing the minimum size factor of the 230-15 tire size designation to '37.30,' and by changing the test rim width of the 165-400 tire size designation to '4.65.' Our review of previous publications show these three items and we will publish a correction regarding them. You also request changed in several load inflation values in Tables I-H and I-N. The November 1, 1973, publication is incorrect with respect to these load values as well, and we will publish a correction regarding them.; We cannot, however, grant your request that we correct in Table I-F th 16 psi (from '705 to '760') for the 5.60 R 15 and 5.90 R 13 tire size designations without first receiving a formal submission from E.T.R.T.O. requesting the change. The 705-pound load is a carryover from earlier Tables, and we cannot conclude that the Table as published on November 1 is in error. Accordingly, if you wish the load value to be modified to 760 pounds you must request such a change in accordance with the abbreviated rulemaking procedures published in the *Federal Register* on October 5, 1968 (33 FR 14964). Upon receipt and approval of E.T.R.T.O.'s submission, we will make the requested change in the subsequent quarterly amendment to the Tables.; You ask in Submission No. 78 that we add to Table I-H the 165 SR 1 tire size designation and the alternate rim size 500b. No amendment is necessary to include the 165 SR 13 tire size designation in Table I-H. Tire size 165 R 13 is listed, and Footnote 1 of the Table allows the 'S' to be placed adjacent to the 'R.' We will, however, add the 5.00B rim as an alternative rim size for the 165 R 13 tire size designation in the next quarterly amendment to the Tables.; We are pleased to be of assistance.

Before discussing the substantive issues raised in your letter, I would like to respond to your request that NHTSA not publicly disclose the details of this product. We hereby grant this request. Your letter, which contains the details of this product will not be made available to the public. As Steve Kratzke of my staff explained to you in a telephone conversation on September 19, all of our interpretation letters are available to the public. Thus, this letter will be publicly available. However, I will not discuss any specific features of your product in this letter. Your letter indicated that your proposed product would alter the alignment of the shoulder belt to increase comfort for the person wearing the shoulder belt. This agency has discussed the legal requirements that might apply to devices that realign the shoulder belt in a February 11, 1988 letter to Mr. Roderick Boutin. I have enclosed a copy of that letter for your information. You should also note that your proposed product would be considered 'motor vehicle equipment,' within the meaning of the National Traffic and Motor Vehicle Safety Act of 1966. I have enclosed an information sheet for new manufacturers of motor vehicle equipment that briefly explains the responsibilities imposed on such manufacturers, and tells how to get copies of the relevant laws and regulations.

ID: aiam4109OpenMr. Arnold Spencer, P.O. Box 516, Rockledge, FL 32955; Mr. Arnold Spencer P.O. Box 516 Rockledge FL 32955; Dear Mr. Spencer: This responds to your March 11, 1986 letter to this office askin several questions about the applicability of our school bus regulations to vans. In a March 5 telephone conversation with Ms. Hom of my staff, you explained your concern with Florida's position against use of conventional vans on school-related activities. While you were aware that it would be more appropriate to discuss your suggestions for changing Florida's laws with state officials, you requested us to clarify our regulations for school buses. Your letter included several specific questions about our school bus requirements.; From the correspondence enclosed with your letter, we understand tha Florida's concern over school bus safety resulted in a prohibition against school boards' condoning the transportation of students to school related events in vans that do not meet Federal or State school bus safety standards. This prohibition applies to school-owned vehicles as well as to vehicles owned by parents wishing to transport their children to extracurricular activities. Florida does not prevent parents from transporting children in their vans if the transportation is not sponsored or required by the school board and if parents assume responsibility for carrying school children.; Before I respond to your specific questions, some background discussio on our school bus regulations would be helpful. The National Traffic and Motor Vehicle Safety Act authorizes NHTSA to regulate the manufacture and sale of all new motor vehicles, including school buses. Under the Vehicle Safety Act we issued comprehensive motor vehicle safety standards for various aspects of school bus safety, including emergency exits, seating systems, windows and windshields, and fuel systems. Under Federal law, a 'school bus' is defined as a bus (i.e., a motor vehicle designed to carry 11 or more persons, driver included) sold for purposes that include carrying students to or from school or related events (common carriers in urban transportation excluded). Federal law requires all manufacturers to certify that each new school bus complies with our school bus safety standards and requires persons selling new school buses to ensure that only certified vehicles are sold. Any person who fails to comply with the requirements of the Vehicle Safety Act is subject to civil penalties under the Act.; In addition, NHTSA has a separate set of recommendations for stat pupil transportation programs which was issued under the Highway Safety Act. Those recommendations are found in Highway Safety Program Standard No. 17, *Pupil Transportation Safety* (copy enclosed), and include guidelines for school bus identification, maintenance, and driver training. Each state determines how it will include Program Standard No. 17's guidelines in its highway safety program, and individual states have chosen to adopt some or all aspects of the standard. Florida state officials would be able to explain state implementation of Program Standard No. 17, if you are interested in further information.; Your first question asked whether we have any regulation that prohibit parents or booster club members from transporting children or students to school sponsored events in their own vehicles.; The answer to your question is no. As explained above, our requirement apply to the manufacture and sale of new motor vehicles. Manufacturers of new school buses certify their vehicles to our school bus safety standards and persons selling new school buses sell only complying school buses. NHTSA does not regulate users of motor vehicles, such as schools, parents, or any other vehicle owner, and we have no prohibition against vehicle owners using their own vehicles to transport school children to school-related events. However, states have authority to set requirements for vehicles used to transport school children. If Florida wishes to sanction use of only complying school buses to transport its school children, it may do so. Its recommendation that school boards not condone transporting school children in noncomplying vehicles is consistent with our belief that school buses certified to our school bus safety standards are the safest means of transportation for school children.; Your second question asked whether NHTSA has any regulation applicabl to state boards of education or booster club members when they purchase or lease a bus or multipurpose passenger vehicle for carrying school children to school-related events.; The answer to this question is no. As explained in our response to you first question, NHTSA's requirements apply to persons selling or leasing new school buses for school-related events, not to purchasers or users of school buses. However, I would like to emphasize that Federal law requires dealers who know that a new bus will be used to transport students to school-related events to sell complying school buses. The Safety Act's prohibition against selling new noncomplying vehicles or introducing them into interstate commence (sic) also requires dealers who *lease* new buses for school-related events to lease complying school buses.; Your next several questions concerned NHTSA's definitions fo 'passenger vehicles,' and 'conventional vans' of varying passenger capacities.; We assume that by 'passenger vehicle' you are referring to a 'passenge car.' NHTSA's definitions section of our motor vehicle safety standards, found at Title 49 of the Code of Federal Regulations (CFR) Part 571.3, defines a 'passenger car' as: 'a motor vehicle ... except a multipurpose passenger vehicle, designed for carrying 10 persons or less.'; You asked for our definition of a 'conventional van' and also asked ho we would classify a passenger van that carries 10 or fewer persons. Vans designed to transport passengers are classified by us as either multipurpose passenger vehicles (MPV's) or buses, depending on the number of persons they are designed to carry. A van which carries 10 or fewer persons and is constructed either on a truck chassis or with special features for occasional off- road operation is considered an MPV.; A 'bus' is defined by us as a motor vehicle designed for carrying mor than 10 persons. Thus, a van designed to carry more than 10 persons is considered a bus. New buses, including the 11 to 15 passenger vans you referred to, sold to carry school children must comply with our school bus safety standards.; Your final question concerned the applicability of our school bu regulations to privately-owned family vehicles used by parents to carry their children to or from school. NHTSA does not consider those vehicles subject to our school bus safety standards. The House Committee Report on the Vehicle Safety Act amendments directing NHTSA to issue school bus safety standards stated that '(p)rivate motor vehicles used to carry members of the owner's household or other students in a carpool arrangement' were among the types of motor vehicles not meant to come within the scope of the amendments. (House Report 93-1191, page 42.) Therefore, persons selling new buses or any other type of vehicle for family use would not be under an obligation to sell complying school buses.; I hope this information clarifies our requirements for school buses Congressman Bill Nelson's office contacted us by letter dated March 4, 1986, with respect to your inquiry. I will send the Congressman a copy of this response for his information.; Please contact my office if you have any further questions. Sincerely, Erika Z. Jones, Chief Counsel |
