The purpose of this legislation is to enhance the safety of children traveling on school buses by requiring the Secretary of Transportation to develop new federal standards for seat belts on these vehicles. The main objective is to ensure that all new school buses are equipped with appropriate seat belts, specifically lap/shoulder belt systems, which are considered to provide the best protection for passengers. Key provisions of the legislation include a mandate for the Secretary of Transportation to publish a notice of proposed rulemaking within 180 days of the law being enacted.
