There is provided in a motor vehicle a time delay operating circuit breaker interposed in the grounding path of the ignition coil with a normally open contact set of a relay in parallel with the circuit breaker. The relay can only be energized if, after the ignition key switch is closed, a concealed switch is momentarily closed. Otherwise, the circuit breaker will after a given time open and no current can flow through the coil so that the vehicle will stop if running.
