"Dear Mr. Martin: This is in regard to your letter of December 9, 1991 regarding school buses. Your three questions are addressed below. 1. (W)hat is the general rule to which states need to comply with regarding Federal school bus safety standards? What bus safety modifications would not be restricted by 15 U.S.C. 1392(d)? Section 103(d) of the National Traffic and Motor Vehicle Safety Act (the Safety Act, 15 U.S.C. 1392(d)) provides that: Whenever a Federal motor vehicle safety standard ... 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 of 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. Nothing in this section shall be construed to prevent ... any State or political subdivision thereof from establishing a safety requirement applicable to motor vehicles or motor vehicle equipment procured for its own use if such requirement imposes a higher standard than that required to comply with the otherwise applicable Federal standard. Section 103(d) preempts state requirements for school buses covering the same aspect of performance as an applicable Federal motor vehicle safety standard (FMVSS) that are different from the applicable FMVSS except to the extent that the requirements impose a higher level of performance and apply only to vehicles procured for the State's use. A state law imposing higher requirement would be preempted under 103(d) to the extent that the law requires all school buses manufactured for use in the state to comply with the law. The law would not be preempted to the extent that it applies to public school buses. The agency has previously interpreted the phrase 'vehicles procured for (the State's) own use' to include public school buses and school buses operated and owned by a private contractor under contract to transport children to and from public school. See, for example, February 20, 1987 letter to Mr. Martin Chauvin (copy enclosed). 2. Would Federal safety standards restrict a state from requiring safety belts on school buses? A state requirement that all school buses be equipped with safety belts regulates the same aspect of performance as the Federal standard for school bus occupant crash protection (FMVSS No. 222, School Bus Passenger Seating and Crash Protection) and would not be identical to that standard for large school buses (those with a gross vehicle weight rating (GVWR) over 10,000 pounds). FMVSS No. 222 requires school buses to provide passenger crash protection through a concept called 'compartmentalization.' Providing compartmentalization entails improving the interior of the school bus with protective seat backs, additional seat padding, and better seat spacing and performance. These interiors are intended to keep occupants in their seating area and protect them during a crash. FMVSS No. 222 requires the additional protection of safety belts at each passenger position in small school buses (10,000 pounds or less GVWR) because these buses experience greater force levels in a crash. A state requirement for safety belts on school buses would be identical to the level of performance required for small school buses, but would specify a different level of performance for large school buses. However, because the state requirement specifies a higher level of performance for large school buses than that required by FMVSS No. 222, Maine may require the installation of safety belts in school buses procured by the State or its political subdivisions, as long as the Federal requirements for compartmentalization are not compromised. 3. Could a school bus fleet modify the rear lighting configuration of their buses (8 light system) to reduce the potential for other vehicles rear-ending buses during poor visibility conditions, e.g., fog? ... The proposed change is to replace the white 8 inch back-up lights with 8 inch red sealed beam warning lights similar to the two at the upper level of the rear end of the bus. These would flash in an alternating criss-cross fashion when the bus is stopped loading or discharging students. The small white lights at the lowest level of the rear end of the bus would each be replaced with white, universal backup lights angled to also direct their beams at 45 degree angles out from the rear of the bus. The answer to your question is yes if the school district or its fleet contractor performs the modification itself. The National Traffic and Motor Vehicle Safety Act (the Safety Act, 15 U.S.C. 1381 et seq.) authorizes this agency to issue FMVSS applicable to new motor vehicles and new items of motor vehicle equipment. Section 108(a)(1)(A) of the Safety Act (15 U.S.C. 1397(a)(1)(A)) prohibits the sale for purposes other than resale of any new motor vehice or item of motor vehicle equipment unless it is in conformity with all applicable FMVSSs. After the first purchase of a vehicle in good faith for purposes other than resale, the only provision in Federal law that affects a vehicle's continuing compliance with an applicable safety standard is set forth in Section 108(a)(2)(A) of the Safety Act (15 U.S.C. 1397(a)(2)(A)). That section provides that: No manufacturer, distributor, dealer, or motor vehicle repair business shall knowingly render inoperative, in whole or in part, any device or element of design installed on or in a motor vehicle ... in compliance with an applicable Federal motor vehicle safety standard. This provision does not regulate in any manner how a vehicle owner can modify his or her vehicle. I note, however, that this agency encourages vehicle owners not to tamper with their vehicle's safety equipment if the modification would degrade the safety of the vehicle. In addition, it is possible that the modifications you describe could be made by one of the named commercial entities without violating the 'render inoperative' provision. The modification you describe affects two requirements of FMVSS No. 108, Lamps, reflective devices, and associated equipment. FMVSS No. 108 requires buses, including school buses, to have at least one backup light meeting the photometric and height requirements of SAE Standard J593c, February 1968. If the small white lights at the lowest level of the rear end of the bus comply with these requirements, the vehicle would continue to conform with this requirement. Section S5.1.4 of FMVSS No. 108 requires school buses to have a system of either four red or four red and four amber signal lamps which conform to SAE Standard J887, July, 1964. The modification you describe would add an additional two red signal lamps to the existing eight light system. Section S5.1.3 of FMVSS No. 108 states that '(n)o additional lamp, reflective device or other motor vehicle equipment shall be installed that impairs the effectiveness of lighting equipment required by this standard.' It is our opinion that the addition of two red signal lamps would not violate this provision. I hope this information is helpful.
