ABSTRACT:
A housing contains a gate or arm to extend to the driver's side of a school bus to stop vehicular traffic at the back of the bus. The housing and the arm are located at the back of the bus by attaching it to the rear bumper of existing bus. For new buses, the housing can be built into the body of the bus on the driver's side near the rear. A stop sign, at eye level, is also extended from the driver's side of the bus. In a preferred embodiment, the sign is extended responsive to the opening of the passenger door on the school bus. As soon as the sign begins its outward movement, flashing lights are activated, a sound alarm is activated. After a short delay, the gate in the form of an arm is extended from the housing. To retrieve the arm and sign, the arm is brought in first and as soon as the arm is retracted it activates a limit switch which begins the sign retraction and when the sign is retracted a limit switch will deactivate the flashing lights and audible device.
