This invention provides a safety arrangement for a dumping vehicle which may include a bumper movable to energize a brake actuator, the bumping being retractable upon tilting of the dumping bed. Modified bumper mounting arrangements are provided for various kinds of vehicles. A latching relay may be included to cause the brake actuator to hold the brakes locked, irrespective of disengagement of the obstruction. The bumper may include a pneumatic chamber with a flexible wall, with a pressure-operated switch for operating the brake actuator. Also, an exteriorly actuated switch may be used in a two-man operation in lieu of a bumper.
