ABSTRACT:
A valve is coupled with a brake line of a vehicle for causing or maintaining vehicle brake application. A switch coupled with a vehicle door regulates operation of the valve. When the vehicle door is open, the switch signals the valve to cause or maintain brake application. A timer coupled with the valve maintains the valve in an applied condition for a predetermined period of time after the door has been closed to allow disembarking passengers adequate time to move away from the vehicle. A sensor may be coupled with the vehicle for determining vehicle speed and preventing operation of the valve when the vehicle is traveling above a predetermined speed.
