Abstract: A clearance enforcement system for a vehicle includes a transceiver to communicate over a data link that communicatively couples the vehicle to a control center external to the vehicle and a management unit configured to enforce a vehicle clearance policy. The vehicle clearance policy specifies that a vehicle must receive, in response to a clearance request message, an affirmative response message from a control center external to the vehicle, before executing a movement associated with the affirmative response message. The management unit enforces the vehicle clearance policy through a computer implemented method. The computer implemented method operates to first automatically determine within the vehicle when the vehicle is initiating the movement without having received the affirmative response and automatically alerting an operator of the vehicle that is initiating the movement without having received the affirmative response message.
