Abstract: A vehicle highly visible, convenient locking apparatus which locks all four wheels of a vehicle to prevent it from being driven or towed is disclosed. The apparatus which holds a brake pedal having a leg, close to a floor of a vehicle comprises: a mountable base having a lower side portion and an opposite side portion; and, a longitudinal member having a bottom end portion adapted to releasably engage in the opposite side portion of the base; a peddle holding/lock member carried by the longitudinal member. In use the base is mounted on the floor of the vehicle, beneath the brake pedal; the longitudinal member is releasably engaged in the base; the peddle is depressed, engaging the brakes; and the peddle holding/lock member is locked on the longitudinal member thereby holding the brake pedal in an engaged position and generally preventing the longitudinal member from turning.
