A system and methodology for monitoring and restricting the use of a mobile communication device while operating a moving vehicle is disclosed. The mobile communications device environmental/geometrical context and the vehicle environmental/geometrical context are self determined, shared and stored locally. This information context is used to restrict a mobile communication device communication channel when motion conditions have been met. Further methods are disclosed to allow the mobile communication device to function normally when local vehicle location and synchronization have been established or an emergency communication channel initiated.
