School bus crossing arm

Pedestrian safety device

A school bus crossing arm is a safety device intended to protect children from being struck while crossing in front of a school bus. Typically, school bus crossing arms are wire or plastic devices which extend from the front bumper on the right side of the bus when the door is open for loading/unloading and form a barrier. The devices force children, who need to cross the road, to stand several feet in front of the bus itself before they can begin to cross the road. This ensures that the bus driver can see them as they cross, avoiding a common blind spot immediately in front of the bus, closest to the bumper. The crossing arm retracts flush against the bumper while not activated, such as when the bus is in motion.
