What does a green arrow on a traffic light mean?

A green arrow on a traffic light indicates that drivers may proceed in the direction that the arrow is pointing. This signal allows for a safe turn or movement because it typically means that oncoming traffic is either stopped or moving in another direction, giving the driver the right of way. When encountering a green arrow, it’s important to confirm the intersection is clear of pedestrians or cyclists before making the turn, but the primary directive is that the driver is authorized to continue forward or turn in accordance with the arrow's indication.

Other signals, such as a solid green light or yellow flashing lights, may suggest different actions, but the green arrow specifically conveys permission to turn or move forward in the indicated direction without needing to yield, enhancing the flow of traffic and ensuring safety at intersections.
