Abstract
A dockboard having movable cross-traffic legs associated therewith, and a latch mechanism which automatically engages and holds the cross-traffic legs in a retracted position when the dockboard is being actively utilized for loading or unloading a truck. The latch mechanism is automatically unlatched following removal of the truck bed from beneath the ramp so that the legs are returned to their active position for supporting the ramp flush with the dock.
