Traffic Control Signals
To control and regulate movement of traffic on junctions, the traffic control signals are used which we commonly known as Traffic Lights. There are three colours of traffic lights we usually see at the junctions which are Red, Amber and Green. Each light depicts a separate meaning which is required to be followed by all the road users. These are usually placed at intersections to control the flow of traffic coming from all directions. It is required that the vehicle should move according to the signals indicated by traffic lights. one must focus on the traffic light placed in front in the direction you are moving. Obeyance of traffic signals helps in managing and regulating the traffic, avoid traffic congestion and prevent road crashes. The junctions where traffic signals are installed are generally called as Traffic Controlled Junctions. The purpose of each traffic light is described hereunder:

Purpose of these lights is to warn the vehicle driver of probable dangers on the road. These signals are placed at medians, service road opening and where traffic merges from subsidiary road to a main road.
