The school bus remains the safest form of surface transportation in the United States. It is far safer than the automobile, truck, public bus, or train. School buses are designed and manufactured specifically for the safety and protection of pupil passengers. Manufacturers must conform to a host of federal standards and certify that each school bus meets all federal and state standards.
The school bus is made up of a straight-body truck chassis with a school bus body mounted on two I-beams. Each area of the school bus body is constructed of a skeletal system beneath the finish and trim elements. The framing elements are heavygauge steel collision beams covered by heavy-gauge steel plates. Emergency personnel have to be specially trained in extrication due to this skeletal framework and the safety cushion built around the pupils.
