Traffic Signals

Traffic signals are helpful to road users, providing information and help to enhance traffic safety and prevent accidents through to the control movement of vehicles and pedestrians at intersections. A good driver must know what each light means and how to proceed when faces them in any situation.

Traffic signs should be sited at the correct distance at side of roads with a clear message, avoiding the reflection in certain zones. Driving knowledge at this point considers three standards of round lights: red, yellow and green; but many countries also use single flashing lights and colored arrows.

Basic Traffic Signals
