Traffic Light

1. A Traffic Light is a type of signal which is used to regulate vehicles and maintain the flow of traffic in an organized manner. The system is usually designed in a vertical formation with LED lights in different colors i.e. red, green and yellow, and it is mounted on a signal pole.

2. This signal system is placed at the intersection of two roads or highways to control the traffic movement. The Red light indicates the stop signal, green for go, and yellow is used to indicate that the signal is about to change.

3. The Traffic Light System is designed to control the traffic in high-density roads and highways where the cars and other vehicles are not expected bend their speed according to the situation. By using this Traffic Light System, the risk of any fatal accidents can also be significantly reduced.

4. Since all vehicles expect to follow the same protocol, the vehicles can move smoothly without any confusion. This saves everyone from the potential accidents which can take place due to any miscommunication or disagreement among the drivers.
