Abstract: A vehicular speed control system is provided including a radio transmitter for transmitting a speed signal indicative of an upper speed limit. Also included is a vehicle having a controller with a first mode of operation for allowing a user to control a speed of a vehicle and a second mode of operation for lowering the speed of the vehicle. The controller operates in the second mode of operation only during the receipt of a disable signal. The vehicle further includes a receiver for receiving the speed signal via free space, a vehicle speed sensor for detecting a current speed of the vehicle, and a comparator for transmitting the disable signal to the controller while the current speed is greater than the upper speed limit received via the speed signal.
