ABSTRACT:
A protective guard is provided for a school bus. A series of telescoping members retracts along the front of the bus, and are in a compact form when the bus is moving. When the school bus stops two of the members telescope outwardly in series and extend across the lane of oncoming traffic. The members are so long and strong that any motorist attempting to pass the bus will damage his car. Flashing red lights are mounted on the extended members. The members are extended and retracted by a lead screw. The lead screw, when it extends the telescoping members, first drives the innermost member outwardly and away from the other movable member. The lead screw then engages the other movable member and drives it outwardly and it carries the innermost member to its ultimate extended position.
