What does a green light in traffic signals signify?

A green light in traffic signals signifies that vehicles can proceed through the intersection or continue moving in the direction indicated by the signal. This is a fundamental aspect of traffic control systems, designed to regulate the flow of traffic and ensure safety on the roads. When drivers see a green light, it is an indication that they have the right of way, provided that it is safe to do so, allowing for the smooth movement of vehicles.

Understanding the meaning of a green light is essential for safe driving, as it informs drivers that they can continue their journey without stopping unless there are specific circumstances, such as pedestrians crossing or emergency vehicles approaching. This is critical for maintaining traffic flow and reducing the likelihood of congestion at intersections.
