A safety bumper system provides both impact protection for a vehicle and its occupants, and also provides fire protection for one or more areas of the vehicle after an impact sufficient to collapse the bumper. A first embodiment comprises a safety bumper assembly for the front and/or rear of a vehicle having a movable outer bumper shell, which is affixed to an inner plate with a relatively fixed bumper support member of the vehicle structure in between the outer bumper shell and inner plate, with compression springs urging the outer shell to an extended position away from the bumper support member, and tension springs urging the inner plate toward the bumper support member. A collapsible bladder is positioned between the outer bumper shell and the fixed bumper support portion, and contains a fire suppressant with a nozzle extending from the bladder to one or more critical areas of the vehicle, e.g., fuel tank and engine. A second embodiment provides a slight contact front bumper which incorporates a pair of push buttons between the bumper and a liner bumper for signaling the driver via a dashboard buzzer or light.
