S.C. Code § 56-5-5010
No person shall sell any new motor vehicle nor shall any new motor vehicle be registered unless such vehicle is equipped with safety glass wherever glass is used in doors, windows, and windshields. The foregoing provisions shall apply to all passenger-type motor vehicles, including passenger buses and school buses. But in respect to trucks, including truck tractors, the requirements as to safety glass shall apply to all glass used in doors, windows, and windshields in the drivers' compartments of such vehicles.
The Department of Motor Vehicles shall not register any motor vehicle which is subject to the provisions of this section unless it is equipped with an approved type of safety glass, and the department may thereafter suspend the registration of any motor vehicle so subject to this section which it finds is not so equipped until it is made to conform to the requirements of this section.
