Abstract: A system and method for engine idle control enforcement is provided. According to one embodiment, a vehicle is monitored to determine whether it has moved a particular distance over a period of time or is moving at a particular speed. The monitoring can be accomplished using, for example, a GPS capable device. A determination can be made based on the vehicle distance or speed over a period of time as to whether the vehicle is in idle. When a determination is made that the vehicle is idle, an activation of one or more relay switches can occur to kill the engine and/or disable the starter. A park gear signal can be used as a safety mechanism to avoid killing the engine when the vehicle is determined to not be in park. In one embodiment, in order to reengage the vehicle's engine, the turnkey must be moved to the OFF position before turning the ignition ON.
