Dear Ms. Amster: This responds to your June 20, 1977, letter concerning Federal schoo bus safety standards. Your letter was forwarded to us by Ms. Margaret Costanza, Assistant to the President, since these standards are promulgated by the National Highway Traffic Safety Administration (NHTSA).; As you may know, several new school bus safety standards are applicabl to school buses built after April 1, 1977. These standards were established in accordance with a directive from Congress in the Motor Vehicle and School Bus Safety Amendments of 1974 (Pub. L. 93-492). Congress enacted that directive after determining that school buses deserved additional safety protection to prevent deaths and reduce injuries.; In your letter, you contend that our standard pertaining to school bu seating (Standard No. 222) requires seat spacing that is too small for older school children. It is our understanding after extensive consultations with bus manufacturers that the new school bus seat spacing requirements result in seat spacing that is essentially equivalent to seat spacing in buses manufactured prior to April 1. Therefore, most new school buses should be manufactured similar to older buses as far as seat spacing is concerned. Some school buses, however, may have slightly reduced seat spacing. We are aware of concerns expressed about reduced seat spacing in some new buses. We are not convinced that the problem originates from the requirements of Standard No. 222, however. Currently, we are examining buses manufactured in accordance with the requirements of the standard to determine whether a modification of the standard is necessary.; Maximum seat spacing has been controlled in buses to provide for th passive restraint of school bus occupants. The seat backs in the new buses are designed to absorb the force of children colliding with them during a crash. If seat spacing were increased, the seats in these buses would not be capable of absorbing sufficient impact force to protect children in accidents. The NHTSA adopted the passive restraint approach to school bus safety in response to public comments claiming that to require only seat belts in school buses would not be sufficient since the belts might not be used by many children. Accordingly, to provide a significant increase in occupant protection, the agency adopted the passive restraint approach to school bus seat safety.; In a final question in your letter, you ask about the costs an benefits of the new school bus safety standards' requirements. The agency has estimated that the total industry cost of compliance with those standards is approximately $40 million annually. The benefits should include a reduction in the number of deaths and injuries resulting from school bus accidents.; If I can be of further assistance to you, do not hesitate to contac me.; Sincerely, Joan Claybrook
