Abstract: An illustrated view of a system for providing enhanced vehicle tracking devices communications. The system provides an activation by alert systems on a vehicle in which it is installed, for example: school bus flashing lights or school zone flashing lights. For police and emergency vehicles, the system is useful for selection of severity of the event such as traffic stop, minor accidents, major accidents, active emergency—avoid area, etc. Further, the system is useful in communicating with existing vehicle alert systems, such as ON-STAR®, or navigation systems indicating the type of alert, severity of the alert, location of the alert and detours resulting from the alert.
