A safety circuit for an electronic throttle control for internal combustion engines, especially for a so-called electronic accelerator system in motor vehicles which include a brake pedal, a set value transmitter coupled to an accelerator, an electronic circuit that acts on a stepping motor, and a clutch interposed between the stepping motor and a throttle actuated by the stepping motor, with the throttle being coupled to an idle return device. The clutch is adapted to be engaged when the accelerator and brake pedal are not simultaneously actuated and when the gas pedal is actuated alone or together with the brake pedal. The clutch is adapted to be disengaged when the brake pedal alone is actuated.
