These provisions apply to all passenger-type motor vehicles, including passenger buses and school buses. With respect to trucks, including truck tractors, the requirements as to safety glazing material apply to all glazing material used in doors, windows, and windshields in the driver's compartments of the vehicles.

(2) The term “safety glazing materials” means glazing materials constructed, treated, or combined with other materials to reduce substantially in comparison with ordinary sheet glass or plate glass the likelihood of injury to persons by objects from exterior sources or by these safety glazing materials when they may be cracked or broken.
