The present invention provides a system and method for degrading and
disabling a vehicle's engine throttle. The vehicle disable system
includes a throttle position sensor that generates a throttle position
signal, an electronic control module ("ECM") input connected to the ECM
on which the throttle position sensor provides the throttle position
signal to the ECM, and an override input that enables an idling signal to
be transmitted to the ECM instead of the throttle position signal. The
method of the present invention includes the steps of receiving an input
signal related to the state of the driver input mechanism, interpreting
the input signal, and at least one of degrading and disabling the
throttle based on the interpretation of the input signal.
