A GPS speed limiter is a speed limiter integrated with GPS to do vehicle speed limit and real-time location monitoring for fleet management. It is a governor used to limit the top speed of a vehicle. For some classes of vehicles and in some jurisdictions they are a statutory requirement, for some other vehicles the manufacturer provides a non-statutory system which may be fixed or programmable by the driver

A vehicle GPS tracker is a device that can be installed in a car to track its location and movements. It can be used to monitor the location of a vehicle in real-time, as well as to keep track of its speed and direction. The GPS tracker can be widely used on cars，trucks,motorcycles,schoolbus,and is to give drivers and passengers security and protection

Special sensors in the vehicle detect the speed it is going with. Then, this information is sent to the electronic control unit (ECU). When the set speed is reached, the ECU restricts the flow of air and fuel to the engine. That way, the top speed of your vehicle is limited and you are not able to exceed it.
