What does a green arrow indicating a turn mean?

Answer: B — You may proceed in the direction of the arrow

A green arrow indicating a turn signifies that you may proceed in the direction of the arrow. This signal provides a clear instruction to drivers, allowing them to make a turn with the assurance that it is safe to do so because oncoming traffic is either stopped or already directed to yield. In this scenario, the green arrow overrides any conflicting signals such as red lights or stop signs, enhancing the efficiency of traffic flow at intersections. The other choices relate to different traffic signals or situations that don’t apply when a green arrow is present. For example, stopping before proceeding is necessary with a red light or stop sign, yielding to opposing traffic might be the case with a green light or a yield sign, and proceeding with caution is important in situations with yellow lights or during any uncertain driving conditions. However, when a green arrow is visible, it directly communicates the permission to turn without additional conditions.
