A fifth wheel release arrangement for releasing a trailer from a towing vehicle in response to a trigger signal. The arrangement comprises one or more externally threaded fasteners and one or more pinion nuts comprising internal threads for engaging the external threads on the threaded fasteners, thereby holding the fifth wheel in position with respect to a first bracket attached to a towing vehicle frame, wherein the externally threaded fasteners are arranged to be rotationally fixed when received by the pinion nuts. The pinion nuts further comprise external teeth for engaging a toothed rack, and the rack is movable by an actuator system, in response to the trigger signal, in a direction to rotate the pinion nuts, whereby the externally threaded fasteners are ejected from the pinion nuts upon moving the rack by the actuator system in the direction, thereby releasing the trailer from the towing vehicle.
