An interlock for the throttle and parking brake of a vehicle for retaining the engine at a predetermined speed until the parking brake is released. Includes a fluid supply conduit connected to the parking brake actuating mechanism. The supply of fluid to the parking brake actuating mechanism is controlled. The parking brake is maintained in the brake engaged position in the absence of fluid supply to the brake actuating mechanism. A linkage is interposed between a first member connected to a vehicle operated control mechanism, and a second member connected to an engine speed control mechanism. The link has a first operating mode for effectively connecting the first and second operating members in a second operating mode for effectively disconnecting the first and second operating members. The first member is placed in its first operating mode when fluid is supplied to the parking brake and is placed in second operating mode when the supply of fluid is discontinued.
