Description: This notice from the Department of Transportation, denies a petition for rule-making filed by Physicians for Automotive Safety (PAS), asking this agency to mandate the installation of seat belts on all school buses. NHTSA believes that the currently mandated occupant protections in school buses provide an adequate level of safety protection, and that seat belts would not raise the level of protection for the occupants unless States and local jurisdictions were willing to take steps to ensure that the seat belts were actually used.
