Vehicle Speed limiter or Speed governor is a device used to restrict the top speed of the vehicle for security reasons, widely used in public service vehicles (buses, school buses) and heavy goods vehicles. Normally speaking, the vehicle is already equipped with an onboard speed limit system prevent the vehicle exceeding certain speed. However in reality usage, the traffic might get dangerous with the pre-controlled speed, especially for school buses, public buses, and heavy construction trucks. Then external speed limiter (speed governor) is needed to ensure the public security.

There are mainly 2 types of vehicle throttle: Electronic throttle and mechanical throttle. Speed limiter is also divided into 2 types: Electronic throttle Speed limiter and Mechanical throttle Speed limiter. The throttle is a mechanism used to control the inlet gases so as to increase or decrease vehicle speed. Typically, the throttle is a butterfly value placed on the entrance of the intake manifold in a fuel-injected engine or in the carburetor in a carbureted engine. Usually the throttle valve is connected and controlled with a throttle pedal in vehicles.
