Systems and processes for automatically bringing a vehicle into compliance with a regulation are provided in order to control for unusual situations, inexperience, reduced ability, and willful disregard by a vehicle operator. An inventive system includes a signal receiver for wirelessly receiving a signal directed specifically to the motorized vehicle while the vehicle is in operation. The signal pertains to a regulation and or emergency command. For example, a signal contains speed limit information and comparison of a parameter of vehicle operation with the requirements of the regulation allows determination of whether the vehicle is in compliance with the regulation. A signal may also include a command by an authority directing the vehicle to slow down or stop, such as in an emergency situation. Where the vehicle is not in compliance with the regulation or command, a control signal is sent to an effector to bring the vehicle into compliance.
