Abstract
A safety system which contains a crossing arm or the like which is mounted on a vehicle, such as a school bus, and normally carried at a retracted position adjacent the vehicle, and a sensor device for sensing the presence of children near the bus which operates in a coordinated fashion with the crossing arm. The sensor may operate either only when the crossing arm is in its retracted position or when the crossing arm is both in its retracted and operating positions.
