Over speeding causes the maximum accidents. Thus, the solution lies in controlling over speeding of transport vehicles thereby inducing discipline amongst drivers through the use of technology. Speed Governor is a device whose primary function is to control the speed of the engine in order to limit the vehicle speed to the pre-specified value. The product operates without effecting driving characteristics. It limits speed but leaves engine power intact. Besides improving road safety tremendously, it is an investment that results in fuel savings, reducing pollution, engine, brake and type wear. This device is mandated by GOI for all the transport and tourist vehicles.
