Abstract
A school bus has a stop sign hinged on an electrical actuator assembly that is attached to the side of the bus. The actuator assembly includes an electric motor that pivots the hinged stop sign from a stored position adjacent the bus to an operative position extending outwardly of the bus in perpendicular fashion and back to the stored position and an electrical control unit that includes Hall effect sensors for controlling the electric motor. These and other components are protected in an outer sealed housing that has a removable cover to facilitate installation and repair. Installation and repair is further enhanced by a removable inner housing sub-assembly that carries the electric motor and the electric control unit and that provides additional protection for these two components. The school bus also has a crossing arm hinged on an identical electrical actuator assembly, that is attached to the front bumper of the bus near the passenger doors.
