What does a green arrow signify when making a left turn?

A green arrow when making a left turn indicates that you can turn left. This signal gives you the right of way to proceed with your turn, meaning that oncoming traffic is stopped, and it is safe for you to make the turn. The presence of a green arrow ensures that you can execute your maneuver without needing to yield to other vehicles or face any obstruction from traffic.

In the context of a traffic signal, a green arrow is a clear directional indicator that allows drivers to proceed in the indicated direction, provided the intersection is clear. It is essential to remain aware of pedestrians and cyclists who may also be present in the intersection, as they still have the right to cross, but the signal specifically grants permission for the left turn.
