All school buses shall have a driver's seat equipped with a one-piece high back, suspension seat designed to minimize the potential for head and neck injuries in rear impacts, providing minimum obstruction to the driver's view of passengers, and meeting applicable requirements. The driver contact area of the cushion and seat back shall be made of soil and wear resistant material. Seat shall be squared and centered ± 1/2 inch behind the steering wheel with a backrest a minimum distance of 11 inches behind the steering wheel. Seat shall be securely mounted to ensure minimal flexing of the seat and the floor panel(s). A Type A bus may have manufacturer’s standard seat.
