Abstract An alarm effective to indicate that a vehicle parking brake is off when the driver moves from the driving position, if at that time, the parking brake is not on. A pressure sensitive means, mounted for example in the base of the driver''s seat, is operatively connected to an alarm so that a signal is issued by the alarm upon movement from the driving position, with the proviso that means are provided for making the alarm insensitive to such movement if the parking brake is on. The alarm is an auxiliary electrical circuit connected in parallel with the ignition system. A switch is provided for selectively and simultaneously opening and closing the vehicle electrical system and the auxiliary circuit, so that the auxiliary circuit can be deenergized, and, if deenergized, the ignition system is deenergized and remains deenergized until the alarm system is activated by closing of the switch.
