What does a traffic signal with a green arrow indicate?

A traffic signal with a green arrow indicates that drivers are permitted to proceed in the direction of the arrow. This signal gives a clear and affirmative instruction that movement is allowed for vehicles, specifically in the direction indicated. It often means that the intersection is clear of oncoming traffic, allowing for safe turns or straight movements, depending on the arrow's direction.

In many traffic systems, a green arrow is also accompanied by a red light for the other directions, signifying that drivers facing the green arrow have the right of way and can move safely without having to yield to oncoming traffic or pedestrians. This clear communication helps in managing traffic flow and reducing potential accidents at intersections, which is critical for safety on the roads.

Understanding the implications of traffic signals like the green arrow is crucial for drivers to follow traffic laws and ensure safety while navigating intersections.
