A device for the control of the traveling speed of a motor vehicle with an electrical controller applied by an actual speed signal and a desired speed signal, an output stage which contains a servo-motor being in operative connection with an element, preferably the throttle valve, which element influences the ratio of the fuel-air mixture that is supplied to the vehicle engine, and the output stage being electrically connected to a first switch which is coupled to the foot brake to switch the output stage into an inoperative condition if the foot brake is actuated. An additional switch which is actuatable by output stage, which switches are disposed in an electrical control circuit (which circuit influences the rotational speed of the engine) are embodied such that if the brake is actuated and if the output stage is outside the idling position the control circuit is controlled in the sense of a reduction of the rotational speed.
