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.

ATTACHMT: MEMO DATED 7-7-87, FROM LACY H. THORNBURG & EDWIN M. SPEAS, TO ERIKA Z. JONES-NHTSA

TEXT: I am responding to your letter of July 7, 1987, where you ask for some assistance with an issue facing your State's public school systems. You stated that some school systems have purchased vans that do not meet Federal school bus specifications. The s chool systems use these noncomplying vans primarily to transport school teachers and administrators, but the vans sometimes are used to transport students to extracurricular activities.

You ask two questions. The first question is whether Federal law prohibits a school system from using a van to transport students to extracurricular activities if the van does not meet Federal school bus standards. The second question is whether the Se cretary of Transportation has adopted a regulation defining the term "significantly" as that term appears in 15 U.S.C. @ 1391(14).

The 1974 amendments to the National Traffic and Motor Vehicle Safety Act (Vehicle Safety Act or VSA) apply to any person manufacturing or selling a new "school bus." NHTSA defines "school bus" as a motor vehicle designed for carrying 11 or more persons, including a driver, and sold or introduced into interstate commerce for transporting students to and from school or school-related events. The VSA does not regulate the manner in which a person, including a school district, uses a vehicle it purchases. Therefore, the answer to your first question is that Federal law does not prohibit a school district from transporting students in a noncomplying vehicle.

On the other hand, the seller of these vans may have sold them in violation of Federal law if the seller had reason to know from factors such as the identify or activities of the purchaser that the purchaser intended to use or convert the vans to school buses. When NHTSA proposed to amend the definition of "school bus" in consequence of the 1974 VSA amendments, we anticipated that there may be circumstances in which a manufacturer has no reason to know that one of its dealers has sold one

of its vehicles as a school bus. The agency expressly stated in the preamble to the proposal that if a dealer knowingly sold any multipurpose passenger vehicle (MPV) or bus capable of being converted and used as a school bus to a school or a school bus contract operator, then the dealer would be responsible for certifying the vehicle's compliance with school bus standards. 40 FR 40854, September 4, 1975.

NHTSA maintains its long-standing position that the seller is the person in the chain of distribution most likely to know of a vehicle's intended use, and remains accountable for selling a vehicle as a school bus if the seller has reason to know whether the buyer intends such use. 40 FR 60033, December 31, 1975.

Your second question involves the term "schoolbus" as it is defined in the Vehicle Safety Act, @ 102(14) [15 U.S.C. @ 1391(14)]. That provision reads:

"'Schoolbus' means a passenger motor vehicle which is designed to carry more than 10 passengers in addition to the driver, and which the Secretary determines is likely to be significantly used for the purpose of transporting primary, preprimary, or se condary school students to or from such schools or events related to such schools." (Emphasis supplied.)

You ask whether the Secretary has adopted a regulation that defines the term "significantly" as it is used in this statutory provision. The answer is no. The question of whether a motor vehicle is "likely to be significantly used" for transporting stude nts is one that the agency finds appropriate to resolve case-by-case, focusing upon the intended use of the vehicle. However, in the final rule amending the definition of "school bus," the agency stated its view that "the Congressional emphasis on 'sign ificant use' of a vehicle (is) a direction to extend the school bus standards to all buses that transport students, whether or not it is their primary purpose." 40 FR 60033, 60034. Emphasis supplied. In expressing this view, NHTSA specifically rejected a Vehicle Equipment Safety Commission (VESC) suggestion that the agency find "significant use" only where a bus was to be used "primarily" for transporting students. Id. Emphasis supplied. Therefore, when the agency considers "significant use," the ques tion of whether a vehicle primarily transports school staff is not determinative.

I hope you find this information helpful.

    Dear Mr. Hoffman:



    This is in reply to your fax of July 25, 2000, with respect to the Funtech 50. You describe the vehicle as a "three-wheel motorcycle with two outrigger wheels (stabilizer wheels)."

    You write that "the stabilizer wheels are not in contact with the ground under normal driving conditions" although a wheel can momentarily touch the ground during a turn. You have asked for an interpretation that the Funtech 50 with its outrigger wheels is a "motor-driven cycle" as we define it.

    For purposes of our jurisdiction, as defined in 49 CFR 571.3(b), a "motorcycle" is "a motor vehicle with motive power having a seat or saddle for the use of the rider and designed to travel on not more than three wheels in contact with the ground." I enclose copies of letters of January 3, 1995, to James D. Murphy, Jr., and June 11, 1986, to Terry W. Wagar providing interpretations that two-wheeled vehicles with outrigger wheels used to provide stability in turns are considered to be "motorcycles." When outrigger wheels serve the same stabilizing purpose on a three-wheeled vehicle such as the Funtech 50, we also consider such a vehicle to be a "motorcycle."

    A "motor-driven cycle" is defined as "a motorcycle with a motor that produces 5-brake horsepower or less." Your letter does not identify the Funtech 50's engine. If it produces 5-brake horsepower or less, the vehicle would be a "motor driven cycle; otherwise," the Funtech 50 is a "motorcycle."

    You also asked for clarification that a three-wheeled motorcycle "can have either two wheels at the front and one wheel at the rear, or, one wheel at the front and two wheels at the rear." We

    confirm your understanding that both configurations are acceptable; the regulatory definition of motorcycle does not specify how three wheels must be arranged.

    If you have further questions, you may phone Taylor Vinson of this Office (202-366-5263).

Chillicothe, MO 64601

Dear Mr. Miller:

This responds to your request for an interpretation regarding the removal of seats from a new 15-passenger Ford E350 Club Wagon, for possible sale to a school. You ask whether the van must meet Federal school bus standards if seats are removed, reducing seating positions to fewer than 10. Our answer is that if the seats were permanently removed prior to the vehicle's sale, the van would not be a "school bus" subject to our school bus standards. However, the vehicle would be considered to be a multipurpose passenger vehicle (MPV) and subject to standards for MPVs.

Your letter states that a "School of Vocational Education" in your area would like the Club Wagon. In a telephone conversation with Dorothy Nakama of my staff, you explained that high school aged students attend the School of Vocational Education ("the School"), and get credit towards high school diplomas for attending the School.

By way of background, the National Highway Traffic Safety Administration (NHTSA) is authorized to issue and enforce Federal motor vehicle safety standards applicable to new motor vehicles, including school buses. In 1974, Congress enacted legislation directing NHTSA to issue safety standards on specific aspects of school bus safety.

Our statute at 49 U.S.C.30112 requires any person selling or leasing a new vehicle to sell or lease a vehicle that meets all applicable standards. Under our regulations, a "bus" is any vehicle, including a van that has a seating capacity of 11 persons or more. Our statute defines a "school bus" as any bus which is likely to be "used significantly" to transport "preprimary, primary, and secondary" students to or from school or related events. 49 U.S.C. 30125. Therefore, a 15-passenger van that is likely to be used significantly to transport students is a "school bus."

Because the School of Vocational Education instructs high school students, NHTSA considers it a "school." If a new 15-passenger Club Wagon is sold or leased to transport students of the School (e.g., leased on a regular or long term basis), the vehicle must meet NHTSA's school bus standards. Conventional 15-passenger vans do not have the safety features necessary for them to be certified as school buses. Therefore, a conventional Club Wagon thus cannot be sold or leased, as a new vehicle, to the School for pupil transportation.

As for removing seats from the van, in an interpretation letter of April 2, 1996 to the Michigan State Police (copy enclosed), NHTSA addressed the issue of dealers reducing seating capacity on a bus to fewer than 11 positions. NHTSA stated the following (see page 3):

If a dealer permanently reduces the seating capacity of a bus to less than 11, the modified vehicle is no longer a "bus." Because the dealer would not be selling a bus, the requirement to sell a school bus does not apply. However, a dealer modifying a new vehicle in this manner would have other responsibilities as a vehicle "alterer" under our regulations (49 CFR 567.7). The dealer would be changing the vehicle's classification to that of a multipurpose passenger vehicle (MPV), and would have to certify that the vehicle complies to the MPV standards.

The letter also addresses several hypothetical situations where dealers lease or sell passenger vans with 5, 8 or 12 seating positions to schools.

You also wish to know whether the van has to meet school bus standards if seating capacity were reduced to 10 or fewer and you obtained a letter from the School stating that it will never transport more than 10 people. As explained above, with seating capacity reduced to less than 11 persons, the vehicle would be subject to the MPV standards. In any event, you appear to be asking whether a school's assurances that it will not carry more than 10 persons in a vehicle enables you to sell non-school buses to the school. The answer is no. A vehicle is a bus depending on whether it is designed for carrying more than 10 persons. The number of persons actually carried in the vehicle has no effect on its classification. Thus, a letter from the school will have no effect on your responsibilities, described in the April 1996 letter, to sell complying vehicles.

I hope this information is helpful. If you have any further questions, please feel free to contact Dorothy Nakama of my staff at this address or by telephone at (202) 366-2992.

Frank Seales, Jr.

Dr. Eng. Eugenic Alzati General Director Ferrari S.p.A. 41100 Moodena Viale Trento Triesta, 31 ITALY

This responds to your letter to Mr. Steed, the Administrator of this agency, asking that Ferrari be allowed to petition for a low volume exemption from the generally applicable passenger automobile fuel economy standards. Ferrari had filed a petition asking such a request for its 1978 model year vehicles, but was ruled ineligible for a low volume exemption because Ferrari was controlled by Fiat, S.p.A. Now that Fiat has stopped importing vehicles into the US, you stated your belief that Ferrari is in the same position as Naserati, which has been ruled eligible to apply for low volume exemption. I need some further information to determine if Ferrari should be considered eligible to film a petition for a low volume exemption.

By way of background, section 502(c) of the Motor Vehicle information and Cost Savings Act (the Act) (15 U.S.C. (2002)(c) provides:

On application of a manufacturer who manufactured (whether or not in the US) fewer than 10,000 passenger automobiles in the second model year proceding the model year for which the application is made, the Secretary may, by rule exempt such manufacturer from (the generally applicable fuel economy standards).

To determine whether Ferrari manufactures fewer that 10,000 passenger automobiles, it is necessary to interpret and apply sections 501(9) and 503(c) of the Act. Section 501(9) specifies: the term "manufacturer" (sic) (except for purposes of section 502(c)) means to produce or assemble in the customs territory of the US, or to import." Section 503(c) reads as follows:

(c) Any reference in this part to automobiles manufactured by a manufacturer shall be deemed-- (1) to include all automobiles manufactured by persons who control, are controlled by, or are under common control with, such manufacturer; and (2) to exclude all automobiles manufactured (within the meaning of paragraph (1) during a model year by such manufacturer which are exported prior to the expiration of 30 days following the end of such school year.

As you noted in your letter, this agency has determined that Naserati is eligible to file a petition for a low volume exemption under section 502(c) of the Act, even though that company is under common control with Nuova Innocenti, S.p.A., which manufactures more than 10,000 passenger automobiles annually. This petition was allowed because NHTSA believes that the term "manufacture" in section 503(c) means to produce or assemble in the US, or to import into the US. Since none of the Nuova Innocenti automobiles are imported into the US, NHTSA concluded that only Naserati's worldwide production should be counted to determine whether that company was eligible for a low volume exemption.

Your situation is potentially similar to the Maserati situation, if the current importers of what formerly were the Fiat X1/9 and Spider 2000 were not found to be under the control of Fiat S.p.A. To make this determination, I will need answers to the following questions:

1. State whether Fiat S.p.A. owns any stock in either industrie Pininfarina S.p.A. or Carrozeria Bertone. If so, please state the extent of such holdings (both in number of shares and the percentage of total shares outstanding).

2. State whether the models which are sold in the US by Pininfarina and Bartone are sold in any other countries. If so, please state whether those models are marketed as Fiats, or whether they are marketed as Pininfarinas and Bartones.

3. State whether the components used by Pininfarina and Bartone when assembling these automobiles are manufactured by those companies or by another company. If any of the components are manufactured by Fiat S.p.A. or any of its subsidiaries, please identify and list each of these components.

4. Your letter had a Feb. 14 l983 letter from Fiat of North America to the Environmental Protection Agency attached thereto. On page 2 of that letter, the following sentence appears: "We would also like to advise you that we will officially be helping Industrie Pininfarine S.p.A. and Carrozeria Bertone in dealing with certification matters in accordance with instructions received from them and Fiat Auto S.p.A." Please detail any and all assistance Fiat of North America currently provides to Pininfarine and Bertone, what assistance was formerly provided, and when the official assistance was ended, if it has been ended.

5. Indicate whether Fiat currently provides any engineering, design, or servicing advice or assistance to Pininfarine and Bertone in connection with the 21/9 or Spider 2000 models. If so, indicate the motors and frequency of such assistance.

The agency will make a prompt determination of Ferrari's eligibility to file for an exemption under section 502(c) of the Act when we receive your answers to these questions. Sincerely, Frank Berndt, Chief Counsel

This responds to your August 22, 1986, letter to former Chief Counsel Jeffrey Miller concerning our regulations for school bus manufacturing. You asked whether the National Highway Traffic Safety Administration (NHTSA) has certified and approved the "Asia Smith Chassis" for school buses. You stated that you need a copy of the certification because Oklahoma requires chassis to be approved by the state Board of Education before they can be sold in Oklahoma.

I would like to begin by clarifying that NHTSA does not certify or approve motor vehicles or motor vehicle equipment. This agency regulates motor vehicle safety under the National Traffic and Motor Vehicle Safety Act. That Act establishes a "self-certification" process under which each manufacturer is responsible for certifying that its products meet all applicable safety standards. This process requires each manufacturer to exercise due care in selecting and conducting the mathematical calculations, computers simulations or testing that form the basis for that certification. Manufacturers certify their school buses by attaching a label to their vehicles in accordance with our certification procedures. The agency periodically tests vehicles and equipment for compliance with applicable safety standards.

A school bus manufacturer who installs a school bus body on a new chassis (such as an Asia Smith chassis) is required by our certification regulations (49 CFR 567 and 568) to certify the completed vehicle to Federal motor vehicle safety standards for school buses. Those regulations require the chassis manufacturer to furnish information which assists the vehicle manufacturer in making that certification. When certifying its school buses, the manufacturer affirms that the vehicle, including the chassis, conforms to all applicable Federal motor vehicle safety standards, including school bus safety standards.

You indicated that Oklahoma requires school bus chassis to be approved by the state before their sale. I am concerned with this requirement because its imposition could be preempted by operation of the Vehicle Safety Act. The first sentence of section 103(d) of the Safety Act states: Whenever a Federal motor vehicle safety standard established under this title is in effect, no State or political subdivision of a State shall have any authority either to establish, or to continue in effect, with respect to any motor vehicle or item or motor vehicle equipment any safety standard applicable to the same aspect of performance of such vehicle or item of equipment which is not identical to the Federal standard.

For your information, I have enclosed a copy of a Federal Register notice issued by the agency concerning the issue of preemption and pre-sale state enforcement of safety standards (47 Fed. Reg. 884; January 7, 1982). The notice discusses NHTSA's position that Federal law preempts state requirements which prescribe the sale of equipment certified to a Federal motor vehicle safety standard unless the equipment is also approved by the State. We believe that Oklahoma's requirement for approval of school bus chassis is analogous.

As I understand Oklahoma's requirement, it imposes requirements which have the effect of proscribing the sale of certified school buses unless their chassis are also approved by the State. Apparently, school buses manufactured with chassis lacking state approval may not be sold in Oklahoma. Even though the vehicle has been certified as meeting all preempted because it imposes burdens differing in a significant respect from the Federal regulatory scheme.

I hope this information is helpful. If you wish to further discuss the preemption issue or have any other questions, please do not hesitate to contact us.

Sincerely,

Dear Mr. Miller:

The August/September 1986 issue of School Bus Fleet magazine has an article about Asia Smith Chassis for school buses. They are marketed by Asia Smith Motor Inc. of Plaistow, New Hampshire.

My question to you is, has this chassis been certified and approved for sale in the United States? If it has been certified, where can I receive a copy of the certification showing that it meets all the federal minimum standards. It is imperative that this information be disseminated to us as our State Board of Education must approve all chassis manufacturers after they receive federal approval.

Thank you in advance for this vital information.

Sincerely,

Melvin Krewall Administrator Transportation Section Finance Division MK:bam
