Abstract: A spring-loaded lever assembly for engaging an ignition related cam or slide for preventing the return of a key and ignition to a key release position, without previously setting the parking brake. For dash-mounted ignitions, a cylinder related cam is engaged via a spring-loaded lock lever head and cable actuated lock lever handle. For column ignitions, the cable actuated lock lever handle and head act in concert with a key actuated linear slide. A buzzer and warning light, in turn, warn of the failure to set the parking brake.
