Dear Mr. Premo: This responds to your December 6, 1977, letter asking which portions o the roof and sidewall structure of your small bus must comply with the head impact requirements of Standard No. 222, *School Bus Passenger Seating and Crash Protection*.; In accordance with the head impact zone requirements outlined i paragraph S5.3.1.1 of the standard, the National Highway Traffic Safety Administration has determined that those portions of your bus constituting the bus sidewall and window structure are not required to comply with the head impact requirements. Only those portions of your bus which constitute part of the roof structure are included within the head impact zone requirements. We have marked in yellow on the enclosed drawing those areas that must comply with the head impact requirements.; Sincerely, Joseph J. Levin, Jr., Chief Counsel
