A method for regulating the speed of a motor vehicle includes the steps of sensing an open door, verifying the authorization of a driver, and preventing the flow of fuel to the engine until an authorized driver has securely closed the vehicle doors. The method also includes the steps of sensing that the driver's seat belt is securely fastened and limiting the flow of fuel to thereby provide a relatively slow speed until the seat belt is fastened and thereafter limiting the flow of fuel to provide a second pre-selected speed. Further, the method includes the steps of overriding the second pre-selected speed and activating a vehicle's flashers when the second pre-selected speed is exceeded. Apparatus for accomplishing the method is also disclosed.
