A speed governor, also known as a speed limiter, is a device installed in a vehicle to limit the maximum speed at which the vehicle can operate. This is often done for safety reasons, to prevent the driver from exceeding a certain speed limit set by the manufacturer or regulatory authorities. Speed governors are commonly found in commercial vehicles, such as trucks and buses, to ensure they do not exceed a safe speed limit.
