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.

"Dear Mr. Kreutziger: This responds to your letter of January 3, 1995 telefaxed to Walter Myers of my staff in which you asked whether the bottom edge of a flip-up school bus seat, when in the vertical position, could extend past the rearward edge of a side emergency exit door a maximum of 3/4 inch. The short answer to your question is no. You enclosed with your letter a copy of Figure 5B of Federal Motor Vehicle Safety Standard (FMVSS) No. 217, Bus emergency exits and window retention and release, which shows the permitted positions of the seats forward and rearward of a school bus side emergency exit door. You drew in a depiction of the flip- up seat bottom showing the seat bottom extending into the access aisle a maximum of 3/4 inch. You stated that even with such intrusion, 11.75 inches of clear aisle space remains without obstruction of the door release mechanism. Paragraph S5.4.2.1(a)(2)(i) of FMVSS No. 217 provides that no seat or restraining barrier shall be installed within the area bounded by a vertical transverse plane tangent to the rearward edge of the door opening frame and a vertical transverse plane parallel to that plane at a distance of 30 centimeters forward of that plane. Paragraph S5.4.2.1(a)(2)(ii) then provides: A seat bottom may be located within the area described in paragraph (a)(2)(i) of this section if the seat bottom pivots and automatically assumes and retains a vertical position when not in use, so that no portion of the seat bottom is within the area described in paragraph (i) when the seat bottom is vertical. (See Figure 5B). (Emphasis added). This requirement for a specific minimum aisle space leading to side emergency exit doors on school buses was contained in the final rule issued by this agency on November 2, 1992 (57 FR 49413) to permit bus occupants unobstructed access to the emergency exit door. The language is very clear. No variation from that requirement is permitted. I hope this information is helpful to you. Should you have any further questions or need additional information, please feel free to contact Mr. Myers at this address or at (202) 366-2992. Sincerely, Philip R. Recht Chief Counsel";

Dear Mr. Cooke: Thank you for your letter of August 19, 1976, to Dr. James B. Gregory requesting information on aftermarket gas caps as they relate to compliance with Federal Motor Vehicle Safety Standard (FMVSS), No. 301. Your inquiry has been forwarded to this office for reply. Apparently your letter of May 26, 1976, was either lost or misdirected, as we can find no record of it in our files, and we sincerely apologize for this delay in responding to your inquiry.; The National Highway Traffic Safety Administration does not regulat vehicle fuel tank caps as such, however, FMVSS No. 301, Fuel System Integrity, specifies performance requirements to assure the integrity of the entire vehicle fuel system (which includes the fuel tank cap) in various crash modes.; Thus, if installation of your replacement cap is accomplished prior t the first purchase of the vehicle for purposes other than resale causing the vehicle's fuel system not to be in compliance with the applicable safety standard, the person installing the cap or offering the vehicle for sale would be in violation of S108(a)(1) of the National Traffic and Motor Vehicle Safety Act (Pub. L. 89-503). That would make the installer or seller subject to civil penalties of up to $1,000 for each violation.; Recent amendments to the Traffic Safety Act (Pub. L. 932-492) prohibi any manufacturer, distributor, dealer, or motor vehicle repair business from knowingly rendering inoperative, in whole or in 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 motor vehicle safety standard (S108(a)(2)(A)). Thus, it is illegal for any of the above named persons to install a fuel tank cap that he knows will cause the vehicle to be in non-compliance with the fuel system integrity standard. Federal Law does not, however, prohibit the owner of a vehicle from purchasing and installing a fuel tank cap of his choice on his own vehicle, even though he may compromise the Fuel System Integrity Standard.; We are interested in any information regarding safety problem associated with replacement gas caps as a basis for further action. If you could provide any such information, we would be most grateful.; Thank you for sharing your thoughts with us. Sincerely, Robert L. Carter, Associate Administrator, Motor Vehicl Programs;

Patricia Mandarino, President

Angel Guard

1049 Larkin Road

Spring Hill, FL 34608

Dear Ms. Mandarino:

This responds to your letter asking about the requirements of the National Highway Traffic Safety Administration (NHTSA) for the Angel Guard, an aftermarket product you have developed that would prevent children in child restraint systems from pressing a vehicles seat belt release button. As explained below, no Federal motor vehicle safety standard specifically applies to your product. However, as a manufacturer of motor vehicle equipment you have certain responsibilities under our laws.

By way of background information, NHTSA is authorized under the National Traffic and Motor Vehicle Safety Act (49 U.S.C. Chapter 301; Safety Act) to issue Federal motor vehicle safety standards that apply to the manufacture and sale of new motor vehicles and new items of motor vehicle equipment. NHTSA, however, does not approve motor vehicles or motor vehicle equipment or pass on the compliance of a vehicle or item of equipment outside the context of an actual enforcement proceeding. Instead, our statute establishes a self-certification process under which each manufacturer is responsible for certifying that its products meet all applicable safety standards. NHTSA also investigates safety-related defects. The following represents our opinion based on our understanding of the information provided by your letter.

Description of the Angel Guard

You enclose a sample of the Angel Guard and describe it as a seat belt release cover which deters small children from disengaging the seat belt which is holding their car or booster seat in place. The Angel Guard appears to be a plastic box-like cover. You state that the device is one piece-no moving parts, and would be secured on existing seat belt assembly systems in motor vehicles. You did not provide instructions on how the device is attached to the seat belt.



Discussion

There is currently no Federal Motor Vehicle Safety Standard (FMVSS) that applies to your product. FMVSS No. 209, Seat Belt Assemblies, sets forth requirements for new seat belt assemblies. Your product does not meet the definition of a seat belt assembly, so the standard would not apply. FMVSS No. 302, Flammability of Interior Materials, generally does not apply to aftermarket equipment items.

Although we do not have any standards that directly apply to your product, as a manufacturer of motor vehicle equipment, you would be responsible for ensuring that your product is free of safety-related defects (see 49 U.S.C. 30118-30121). I have enclosed an information sheet that briefly describes those responsibilities.

There are other requirements of this agency of which you should be aware. Section 30122 of 49 U.S.C. (Making safety devices and elements inoperative) prohibits commercial businesses from knowingly making inoperative devices or elements of design installed in a motor vehicle or on an item of motor vehicle equipment, such as a vehicle seat belt assembly, in compliance with the FMVSSs. There are several seat belt elements of design that could be affected by your product, which we will discuss below. The make inoperative provision does not apply to individual owners installing aftermarket equipment on their own vehicles. However, it is our policy to encourage vehicle owners not to tamper with or otherwise degrade the performance of safety systems.

Subparagraph (d) Buckle release of S4.3 Requirements for hardware, of FMVSS No. 209 requires the pushbutton release for any buckle on a seat belt to have a minimum area for applying the release force. Subparagraph (d) also requires the buckle to release when a specified maximum force is applied. It appears that, by design, your product would cover the button and not allow the buckle to release under the amount of force specified by FMVSS No. 209. If your device would interfere with the vehicles compliance with these requirements, commercial establishments installing your device on customers seat belt assemblies would be subject to fines for violating the make inoperative provision.

Manufacturers of devices that interfere with the operation of the seat belt release should carefully evaluate the effect of the product on the performance of vehicle safety belts. For example, you should ensure that your product would not interfere with seat belt retraction or release in an emergency, that any sharp edges that your product has would not cause deterioration of the seat belt webbing, that your product would not obscure the information required by FMVSS No. 209 to be labeled on the webbing, and that the buckle will be able to be released should emergency egress from the vehicle be necessary. Further, seat belt webbing is designed to have some "give" to help absorb crash forces. If your product were to present a design that could harm an occupant, it would raise safety concerns. Finally, you should be aware that originally-installed safety belts must meet the flammability resistance requirements of FMVSS No. 302. Again, we would encourage you to evaluate your product against the requirements of these standards.



State Law May Apply

Additionally, the States have the authority to regulate the use of vehicles, and may have restrictions on the use of devices that restrict the release of seat belt buckles. We suggest that you check with your attorney or insurance company about State law considerations.

Enclosed is the sample of your product that you sent us. If you have any further questions please call Ms. Dorothy Nakama of my staff at (202) 366-2992.

Sincerely yours,

Anthony M. Cooke

Dear Mr. Rogers: Thank you for your letter on your constituent's behalf to former Chie Counsel Frank Berndt asking several specific questions about our motor vehicle safety standards for school buses. I hope this information is helpful to you in responding to your constituent. If you or your constituent need further clarification about how our requirements apply in a specific situation, please let me know.; Your questions were as follows: >>>1. Can a vehicle designed, manufactured, and sold as a truck, eve be considered a 'school bus' unless remanufactured, modified, or converted by a manufacturer or a manufacturer's dealer or distributor and certified as a school bus?<<<; The answer to your question depends on whether you are asking about vehicle being considered a 'school bus' under State or Federal law. Under Federal law, which applies to the manufacture and sale of new motor vehicles, the answer is no. A vehicle is certified only once, when manufactured as a new vehicle. With the one exception discussed below, there is no provision in our statutes or regulations for recertification of a used vehicle which has been modified so that it falls into a different category of vehicles. The National Traffic and Motor Vehicle Safety Act and regulations issued thereunder require manufacturers to classify their new motor vehicles and certify that their vehicles meet all Federal motor vehicle safety standards applicable to the vehicle type. Those determinations are only made by the manufacturer at the time the vehicle is originally manufactured. Since both the physical attributes underlying the vehicle types and the applicable safety requirements differ from type to type, a vehicle can be classified only as a single type. Therefore, a new vehicle manufactured and sold as a 'truck' is certified as meeting our safety standards for trucks and cannot be certified also as a vehicle meeting safety standards for school buses.; Our regulations do not prohibit used trucks from being modified fo pupil transportation purposes. Since our certification requirements apply only to the manufacture or alteration of new motor vehicles, the person performing the modification does not recertify the vehicle as a 'school bus' unless the modification of the vehicle is so extensive as to constitute a manufacture of a new vehicle. For example, a used truck chassis lacking requisite systems required by our regulations might be combined with a new school bus body. The completed school bus would be considered newly manufactured, and would have to be certified as a 'school bus.'; Used trucks which have been modified to carry school children might b considered 'school buses' under State law. State definitions of school buses determine the applicability of school bus operational requirements to vehicles. If the modifications to a truck bring it within a State's definition of 'school bus,' then the vehicle would be considered a school bus under State law and would have to comply with State requirements for school buses in order to be properly used as a school bus in that State.; >>>2. Do Federal Motor Vehicle Safety Standards apply only t manufacturers, their dealers and distributors?<<<; The answer to your question is no, because our motor vehicle safet standards apply to anyone who manufactures, distributes or sells new motor vehicles. Federal law requires manufacturers of new school buses to certify that their vehicles comply with all applicable school bus safety standards. In addition, distributors and sellers of new school buses must ensure that only complying school buses are sold. While new school buses are typically sold by their manufacturers or manufacturers' distributors and dealers, the responsibility to sell complying school buses rests with any person selling new school buses.; The Vehicle Safety Act applies also to persons who perfor manufacturing operations on previously certified *new* vehicles prior to the vehicles' first purchase in good faith for purposes other than resale.; Such persons are considered 'alterers' under our regulations and ar subject to requirements that they certify compliance with Federal Motor Vehicle Safety Standards. Alterers who significantly affect the configuration of a new motor vehicle previously certified to applicable safety standards must certify that the new vehicle, as altered, conforms to all applicable safety standards affected by the alteration in effect on the date of manufacture of the original vehicle or on the date the alterations were completed.; In addition, the Vehicle Safety Act applies to commercial businesse performing operations on *new and used* motor vehicles. Section 108(a)(2)(A) of the Vehicle Safety Act (copy enclosed) states, in part:>>>No manufacturer, distributor, dealer or motor vehicle repair 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, the requirements of our motor vehicle safety standards affec those aforementioned parties modifying or repairing new or used motor vehicles, by setting limits on the operations performed on those vehicles. Those persons are prohibited from either removing, disconnecting or degrading the performance of safety equipment installed in compliance with an applicable safety standard. There is no prohibition against an individual owner modifying his or her own vehicle.; >>>3. What is the difference between a tamperer and a modifier as the relate to Federal Motor Vehicle Safety Standards?<<<; Our regulations do not define the terms 'modifier' and 'tamperer. However, the terms are commonly used to describe persons who make changes to vehicles. The term 'modifier' is often used to describe persons making changes to new or used vehicles. As explained above, persons modifying a new motor vehicle prior to its first purchase are considered 'alterers' under our regulations and are subject to requirements that they recertify the vehicle. Commercial parties involved with modifying new or used vehicles are subject also to the 'render inoperative' prohibitions of Section 108(a)(2)(A).; 'Tamperers' often refer to persons modifying or removing safety system or equipment on used vehicles. Commercial parties involved in tampering are subject to the 'render inoperative' prohibitions of Section 108(a)(2)(A). Violations of section 108(a)(2)(A) are punishable by civil penalties up to $1,000 per violation. Again, our regulations do not apply to individual owners modifying their own vehicles. Such modifications, however, would have to comply with State law.; >>>4. Who can make the certification that a vehicle meets applicabl Federal Motor Vehicle Safety Standards?<<<; Under the Vehicle Safety Act, manufacturers of new motor vehicle certify that their vehicles comply with all applicable motor vehicle safety standards. As suggested above, 'alterers' are considered to be motor vehicle manufacturers and therefore are also subject to certification requirements. Alterers certify that the vehicle, as altered, conforms to applicable safety standards affected by the alteration.; >>>5. Does the date of manufacture of a vehicle determine the specifi Federal Motor Vehicle Safety Standards that the vehicle has to meet?<<<; In general, the answer to this question is yes. The date of manufactur is one factor determining applicability of our motor vehicle safety standards. Each motor vehicle manufactured on or after the effective date of a safety standard is subject to requirements of that standard if, of course, the standard applies to that vehicle type. However, as explained above, 'alterers' affecting compliance with Federal safety standards by their alteration may choose the completion date of the alterations as the date by which to certify.; >>>6. Are passenger restraint systems required on school buses with manufacture date prior to April 1, 1977?<<<; In 1974, Congress directed NHTSA to issue motor vehicle safet standards for various aspects of school bus safety. Pursuant to that mandate, we issued Standard No. 222, *School Bus Passenger Seating and Crash Protection*, which requires school buses to provide a passenger restraint system through a concept called 'compartmentalization.' The standard became effective on April 1, 1977, and applies to each school bus manufactured on or after that date. School buses manufactured prior to April 1, 1977, are not subject to compartmentalization requirements.; >>>7. Are there any Federal Motor Vehicle Safety Standards applicabl only to school buses prior to April 1, 1977?<<<; The answer is no. There are three safety standards that we issue exclusively for school buses, i.e., Standards No. 220, *School Bus Rollover Protection*, No. 221, *School Bus Body Joint Strength*, and No. 222, *School Bus Passenger Seating and Crash Protection*. Those standards became effective April 1, 1977.; >>>8. Do school buses manufactured prior to April 1, 1977, have to mee FMVSS No. 217 and FMVSS No. 222?<<<; Standard No. 217 became effective September 1, 1973. School buse manufactured on or after that date and prior to April 1, 1977, had to meet Standard No. 217 *if* push- out windows or other emergency exits were provided. Pursuant to the 1974 Congressional mandate, NHTSA amended Standard No. 217 to require school buses manufactured on or after April 1, 1977, to contain additional emergency exits and set special requirements for those exits.; Standard No. 222 became effective on April 1, 1977. School buse manufactured prior to that date do not have to meet that standard.; Again, please contact my office if you or your constituent have an further questions.; Sincerely, Erika Z.

If the modifications to a truck bring it within a State's definition of 'school bus,' then the vehicle would be considered a school bus under State law and would have to comply with State requirements for school buses in order to be properly used as a school bus in that State.; >>>2. Do Federal Motor Vehicle Safety Standards apply only t manufacturers, their dealers and distributors?<<<; The answer to your question is no, because our motor vehicle safet standards apply to anyone who manufactures, distributes or sells new motor vehicles. Federal law requires manufacturers of new school buses to certify that their vehicles comply with all applicable school bus safety standards. In addition, distributors and sellers of new school buses must ensure that only complying school buses are sold. While new school buses are typically sold by their manufacturers or manufacturers' distributors and dealers, the responsibility to sell complying school buses rests with any person selling new school buses.; The Vehicle Safety Act applies also to persons who perfor manufacturing operations on previously certified *new* vehicles prior to the vehicles' first purchase in good faith for purposes other than resale. Such persons are considered 'alterers' under our regulations and are subject to requirements that they certify compliance with Federal Motor Vehicle Safety Standards. Alterers who significantly affect the configuration of a new motor vehicle previously certified to applicable safety standards must certify that the new vehicle, as altered, conforms to all applicable safety standards affected by the alteration in effect on the date of manufacture of the original vehicle or on the date the alterations were completed. In addition, the Vehicle Safety Act applies to commercial businesses performing operations on *new and used* motor vehicles. Section 108(a)(2)(A) of the Vehicle Safety Act (copy enclosed) states, in part:; >>>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, the requirements of our motor vehicle safety standards affec those aforementioned parties modifying or repairing new or used motor vehicles, by setting limits on the operations performed on those vehicles. Those persons are prohibited from either removing, disconnecting or degrading the performance of safety equipment installed in compliance with an applicable safety standard. There is no prohibition against an individual owner modifying his or her own vehicle.; >>>3. What is the difference between a tamperer and a modifier as the relate to Federal Motor Vehicle Safety Standards?<<<; Our regulations do not define the terms 'modifier' and 'tamperer. However, the terms are commonly used to describe persons who make changes to vehicles. The term 'modifier' is often used to describe persons making changes to new or used vehicles. As explained above, persons modifying a new motor vehicle prior to its first purchase are considered 'alterers' under our regulations and are subject to requirements that they recertify the vehicle. Commercial parties involved with modifying new or used vehicles are subject also to the 'render inoperative' prohibitions of Section 108(a)(2)(A).; 'Tamperers' often refer to persons modifying or removing safety system or equipment on used vehicles. Commercial parties involved in tampering are subject to the 'render inoperative' prohibitions of Section 108(a)(2)(A). Violations of Section 108(a)(2)(A) are punishable by civil penalties up to $1,000 per violation. Again, our regulations do not apply to individual owners modifying their own vehicles. Such modifications, however, would have to comply with State law.; >>>4. Who can make the certification that a vehicle meets applicabl Federal Motor Vehicle Safety Standards?<<<; Under the Vehicle Safety Act, manufacturers of new motor vehicle certify that their vehicles comply with all applicable motor vehicle safety standards. As suggested above, 'alterers' are considered to be vehicle manufacturers and therefore are also subject to certification requirements. Alterers certify that the vehicle, as altered, conforms to applicable safety standards affected by the alteration.; >>>5. Does the date of manufacture of a vehicle determine the specifi Federal Motor Vehicle Safety Standards that the vehicle has to meet?<<<; In general, the answer to this question is yes. The date of manufactur is one factor determining applicability of our motor vehicle safety standards. Each motor vehicle manufactured on or after the effective date of a safety standard is subject to requirements of that standard if, of course, the standard applies to that vehicle type. However, as explained above, 'alterers' affecting compliance with Federal safety standards by their alteration may choose the completion date of the alterations as the date by which to certify.; >>>6. Are passenger restraint systems required on school buses with manufacture date prior to April 1, 1977?<<<; In 1974, Congress directed NHTSA to issue motor vehicle safet standards for various aspects of school bus safety. Pursuant to that mandate, we issued Standard No. 222, *School Bus Passenger Seating and Crash Protection*, which requires school buses to provide a passenger restraint system through a concept called 'compartmentalization'. The standard became effective on April 1, 1977, and applies to each school bus manufactured on or after that date. School buses manufactured prior to April 1, 1977, are not subject to compartmentalization requirements.; >>>7. Are there any Federal Motor Vehicle Safety Standards applicabl only to school buses prior to April 1, 1977?<<<; The answer is no. There are three safety standards that we issue exclusively for school buses, i.e., Standards No. 220, *School Bus Rollover Protection*, No. 221, *School Bus Body Joint Strength, and No. 222, *School Bus Passenger Seating and Crash Protection*. Those standards became effective April 1, 1977.; >>>8. Do school buses manufactured prior to April 1, 1977, have to mee FMVSS No. 217 and FMVSS No. 222?<<<; Standard No. 217 became effective September 1, 1973. School buse manufactured on or after that date and prior to April 1, 1977, had to meet Standard No. 217 *if* push- out windows or other emergency exits were provided. Pursuant to the 1974 Congressional mandate, NHTSA amended Standard No. 217 to require school buses manufactured on or after April 1, 1977, to contain additional emergency exits and set special requirements for those exits.; Standard No. 222 became effective on April 1, 1977. School buse manufactured prior to that date do not have to meet that standard.; Again, please contact my office if you or your constituent have an further questions.; Sincerely, Erika Z.

Dear Mr. Alexander: This responds to your March 20, 1984, letter to the National Highwa Traffic Safety Administration (NHTSA), concerning the Federal school bus safety standards administered by this agency. You asked three questions regarding passenger seating in school buses and the classification of vehicles as school buses.; Specifically, your questions asked: >>>(a) There are 9 students plus the driver, for a total of 10 people in a school bus. For purposes of the definition of a school bus, is the driver a passenger?<<<; Section 571.3 of the Code of Federal Regulations defines a 'school bus as a bus that transports children to or from school or related events. Our regulations further define 'bus' as a vehicle designed for carrying more than 10 persons. The driver is considered a 'person' under our regulations. Thus, it may be useful to remember that any vehicle that carries more than 10 *persons* is a bus. Your vehicle which seats 9 students plus the driver, for a total of 10 persons, would not be considered a school bus.; >>>(b) If a van is originally designed for 11 passengers plus a drive and, because the definition of a school bus, the school system desires to alter the number of seat spaces by removing seats so that the van will accommodate 9 pupils plus the driver, will this alteration in any way conflict with the definition of vehicle capacity? (I would assume that any structural changes would place liability in the event of accident attributable to that alteration on the local school system making the change.) <<<; In asking whether the alteration will 'conflict with the definition o vehicle capacity,' we assume that you are asking whether removing the seats of the vehicle changes the classification of that vehicle as a bus. Your letter is not clear whether it is a dealer who will be modifying the vehicle prior to its sale to the school system, after its sale to the school system, or whether the school itself will be modifying the bus after purchasing the vehicle. We will address these situations in our answer.; Altering an 11-passenger van by removing some of its seats so that i would no longer be of a passenger capacity that would classify it as a bus is, in theory, permissible. If a dealer makes such a modification before the vehicle is sold to you, it must attach an alterer's label in accordance with Part 567.7, *Certification*, of our regulations. Since the dealer would be changing the vehicle type from a bus to a multipurpose passenger vehicle, it must make sure that the vehicle complies with all of the standards applicable to that new vehicle type. This might be difficult since some different standards apply to multipurpose passenger vehicles than apply to buses.; If the modifications to the vehicle are made by a business such as garage after you purchase the vehicle, the persons modifying the vehicle must not knowing (sic) render inoperative the compliance of your vehicle with any applicable safety standard. Section 108(a)(2)(A) of the National Traffic and Motor Vehicle Safety Act prohibits motor vehicle manufacturers, distributors, dealers and repair businesses from rendering inoperative equipment or designs that are incorporated in motor vehicles in compliance with the Federal motor vehicle safety standards. This means that a person in any of the above categories would not be permitted to destroy the vehicle's compliance with any safety standard by the removal of the seat.; The prohibition against rendering inoperative does not apply to a owner, such as a school or a state, which modifies its own vehicles. A school modifying its own vehicles need not assure that the vehicles comply with the Federal school bus safety standards. However, you are correct in assuming that your school could incur substantial tort liability in the event of an accident involving a vehicle that was not in compliance with the appropriate safety standards. This matter should be discussed with your insurance company and attorney. You should further determine whether your State law would prohibit the use of these vehicles to transport school children.; >>>(c) On a 60-passenger school bus, all of the seats except the thre rows in the front are removed. Each seat is 39 inches in width and is used to accommodate two high school pupils. The vehicle color is something other than yellow. A floor-to-ceiling barrier, with an emergency opening, is installed behind the three rows of seats. Supplies, materials, tools, equipment, etc., are transported in the rear of the vehicle with up to 12 youngsters plus the driver in the front portion. Given that all these factors exist at one time, will this vehicle be in conflict with any federal standards? If so, which ones?<<<; There are several areas of school bus safety which could be affected b the proposed modification of the vehicle. Since the vehicle will be carrying more than 10 persons, it is categorized as a bus, and classified by its use as a school bus. A threshold issue related to the question you asked concerns, again, the possibility that removing the bus seats will render inoperative the vehicle's compliance with the Federal school bus safety standards. The issue depends on whether it is a garage-type business that will be altering the bus, or the school. Modification of a safety system so that it no longer complies with all applicable safety standards in effect on the date of the vehicle's manufacture would be a violation of Section 108(a)(2)(A). As discussed earlier, this prohibition does not apply to an owner, such as a school or a state, which modifies its own vehicles. A school may make any modification that it chooses to its buses. Such action does not violate the Vehicle Safety Act or render the school subject to any penalty under the Act.; However, as you know, private liability might occur if th modifications took the vehicle out of compliance with the safety standard and a student was subsequently injured in one of the buses. Accordingly, the modifications you make should not negatively affect the compliance of your vehicle with the safety standards.; The removal of the bus seats does not appear likely to affect adversel your vehicle's compliance with the Federal safety standards. Those standards do not require the installation of any specific seats or any specified number of seats in school buses. Instead, the standards specify that certain requirements must be met for any seat that is installed. Therefore, if the bus complied with the requirements of the Federal school bus safety standards before its alteration, the proper removal of the seats would not affect the vehicle's compliance.; You propose to install a floor-to-ceiling barrier in the vehicle behin the three rows of seats. Your letter does not describe this barrier in detail, but states that it contains an emergency opening. We are concerned that this barrier would render the vehicle in noncompliance with the requirements for emergency exits found in FMVSS No. 217, *Bus Window Retention and Release*.; Standard No. 217 regulates the number and size of school bus emergenc exits and requires that the release mechanisms of those exits be readily accessible. The purpose of these requirements is to provide an easily operable, unobstructed school bus emergency exit. In the past, the agency has preempted a State requirement for a safety chain that would have been placed across an exit, because we viewed the chain as providing an obstruction to the opening. We have also interpreted the Standard to prohibit a ramp used for transporting the handicapped when the ramp partially blocked the rear emergency exit when it folded into the bus. Your letter did not describe in detail the floor-to-ceiling barrier in your bus and we are unable to form an opinion as to the compliance of the altered vehicle with Standard No. 217. However, if the barrier provides an impediment to the emergency exit then the alteration might conflict with FMVSS No. 217. Further, if the barrier conflicted with Standard No. 217, then it could not be added as aftermarket equipment by any manufacturer, dealer, or repair business, without rendering inoperative the compliance of the bus with the safety standard.; Finally, you indicated that the school bus would be a color other tha yellow. Highway Safety Program Standard No. 17 formerly permitted school vehicles carrying 16 or less students to or from school (i.e., 'Type II' school vehicles) to be marked, painted, and lighted in one of two ways. The buses could be either marked, painted, and lighted as school buses, or marked painted, and lighted differently than school buses. However, all school buses now must have the lighting of a school bus required under Federal Motor Vehicle Safety Standard No. 108, *Lamps, Reflective Devices, and Associated Equipment*. since all school buses must have the lighting of a school bus, under Highway Safety Program Standard No. 17 they also must have the painting and marking of a school bus.; Sincerely, Frank Berndt, Chief Counsel

Dear Mr. Smallwood: This is in reply to your letter of April 26, 1979, with respect to you wish to import used truck tire casings for the purposes of recapping. You have been advised in a telephone conversation with our Office of Vehicle Safety Compliance that there are two ways to do this: the casings must bear DOT markings, or be accompanied by some proof that they were manufactured before March 1, 1975, the effective date of the truck tire standard, Federal Motor Vehicle Safety Standard No. 119. So believe that this is impossible and have requested our advice.; There is an additional solution whose feasibility we will leave to you determination. While Section 108(a)(1)(A)(15 U.S.C. 1397(a)(1)(A)) of the National Traffic and Motor Vehicle Safety Act, as we interpret it, prohibits the importation of used truck tires that do not comply with Standard No. 119, Section 108(b)(3) (15 U.S.C. 1397 (b)(3)) allows their importation under bond 'to insure that any such [tire] will be brought into conformity with any applicable Federal motor vehicle safety standard' (The corresponding provision of the importation regulation is 19 CFR 12.80(b)(i)(3)). Since the agency presently has no standard that applies to the retreading of truck tires, the applicable standard would be that in effect when the tires was new - Standard No. 119. Thus, if Montgomery Tires Service can demonstrate that its retreaded truck tires conform to Standard No. 119, and are willing to affix a DOT symbol to each tire as certification of that fact, your casings may enter the country under bond as provided for in 19 CFR 12.80 (b) (i) (3), releasable when upon an affirmation of compliance to Standard No. 119.; Sincerely, Frank Berndt, Chief Counsel

Dear Mr. Carnahan: This responds to your May 10, 1979, letter asking about modification of buses to reduce seating capacity so that they no longer must comply with school bus safety standards.; First, let me clarify several points. In applying motor vehicle safet standards, we define a 'school bus' as a bus that transports children to or from school or related events. Our regulations further define 'bus' as a vehicle designed for carrying more than 10 persons. The phrase 'more than 10 persons' includes the driver. Accordingly, any vehicle that transports 11 people is a bus.; Your first problem appears to involve how to determine whether vehicle is designed to carry more than 10 persons. You indicate, for example, that some manufacturers have attached labels to their vehicles stating that they are designed to transport 15 passengers. However, some of the vehicles only have 8 or 9 seats. The National Highway Traffic Safety Administration measures vehicle capacity by the number of designated seating positions. Therefore, a vehicle that has 8 designated seating positions is not a bus. Such a vehicle would be a multipurpose passenger vehicle. If you are unsure of the vehicle type, refer to the vehicle certification label located on the door pillar post or on the inside of the door. That label lists the vehicle type as established by its manufacturer.; Any vehicle that is sent from its manufacturer and certified i compliance with multipurpose passenger vehicle (MPV) standards may be used to transport school children. These vehicles, since they are not buses, need not comply with the school bus safety standards. On the other hand, any vehicle that is certified as a bus, but not a school bus, should not be used to transport school children.; You ask whether a bus can be modified by removing seats so that i would no longer be of a passenger capacity that would require it to comply with the school bus safety standards. In theory such a modification is permissible. If a dealer makes such a modification, it must attach an alterer's label in accordance with Part 567.7, *Certification*, of our regulations. Since the dealer would be changing the vehicle type (from bus to MPV), it must make sure that the vehicle complies with all of the standards applicable to the new vehicle type. This might be difficult since some different standards apply to multipurpose passenger vehicles than apply to buses. However, it is conceivable that the initial vehicle manufacturer might be able to assure the dealer that the vehicle was built in compliance with all necessary standards. In such a case, the dealer could attach a label, and the vehicle would be properly certified.; If a school modifies its own vehicles, it need not attach a label Also, it need not assure that the vehicles comply with any standards. In the event of an accident, however, a school could incur substantial liability if it were operating a vehicle that was not in compliance with the appropriate safety standards.; In your final question you ask what agency enforces the standard against dealers and manufacturers. The National Highway Traffic Safety Administration enforces all of the motor vehicle safety standards.; Sincerely, Frank Berndt, Chief Counsel
