Road Speed Breaker

A speed breaker is a hump surface across the roadway having a rounded shape with width greater than the wheel base of most of the vehicles using the road.Speed breakers commonly referred to as speed humps or speed bumps are traffic calming devices commonly installed to reduce speed-related accidents. They are a great example of an improved driving experience for road users while reducing costs and improving the environment at the same time.Speed breakers are used to slow down traffic near schools, hospitals so that children can cross the road more easily or senior citizens can cross at ease. They are also placed near toll booths and entry points of bridges or narrow roads, to ensure that motorists reduce their speed.By definition a circuit breaker is an electrical safety device, a switch that automatically interrupts the current of an overloaded electric circuit, ground faults, or short circuits. Circuit breakers "trip", shut off, current flow after protective relays detect a fault.
