speed governor is a device designed to control and limit the maximum speed of a vehicle or machine. It works by regulating the fuel supply, engine power, or electronic controls to ensure that the set speed limit is not exceeded. Speed governors are commonly installed in commercial vehicles, buses, trucks, and fleet vehicles to improve road safety, reduce accidents caused by overspeeding, and enhance fuel efficiency. They also help organizations comply with government transport regulations. Modern speed governors often include electronic systems that provide accurate speed control, reliability, and easy monitoring, making them an essential component for safe and responsible vehicle operation
