What is the purpose of a green traffic light?

The purpose of a green traffic light is to indicate that vehicles are allowed to proceed through the intersection or continue along the road, assuming it is safe to do so. When the light is green, drivers have the right of way and can move forward without stopping, as long as the intersection is clear of other vehicles and pedestrians. This signal is crucial for maintaining the flow of traffic and ensures that drivers understand when it is appropriate to continue their journey safely.

In contrast, stopping vehicles is indicated by a red light, while a yellow light generally signals the need to prepare to stop. A green light does not serve as a warning for hazards; instead, it directs drivers to move ahead when conditions permit. Understanding the meaning of traffic signals, particularly the green light, is a fundamental aspect of safe driving practices.
