49. The driver of a school bus, when transporting a handicapped school child, shall
(1) assist the child in getting on and off the bus, where the child requires his assistance;
(2) immobilize the child’s wheelchair, if he has one, and ensure that the seat belt that must be worn by the child is buckled before continuing his route;
