What does a green arrow pointing left mean?

A green arrow pointing left indicates that you may turn left while oncoming traffic is stopped. This signal provides clear guidance that the intersection has been designated as safe for a left turn, allowing vehicles to proceed without having to yield to oncoming traffic. The presence of the green arrow typically indicates that traffic lights or signals for opposing lanes are red, stopping those vehicles and providing a clear path for those turning left.

This is particularly relevant in busy intersections, where drivers need clarity about their right-of-way. The green arrow is a definitive signal that prioritizes the left-turning vehicles, promoting smooth traffic flow and reducing the potential for accidents at intersections. And while there could be other factors to consider, such as pedestrians or cyclists, the primary meaning of the green arrow is to indicate that a left turn is permitted.
