What does a green arrow indicate at a traffic signal?

A green arrow at a traffic signal indicates that you may proceed in the direction the arrow is pointing. This signal provides a clear instruction for drivers, allowing them to make a turn or proceed straight safely, as it usually means that oncoming traffic is either stopped or has been halted by a red light. It signifies that the right of way is granted to the driver, and it is a go-ahead to continue driving in that specific direction without yielding to other vehicles or pedestrians, though caution should always be exercised.

The other options suggest actions that do not align with the meaning of a green arrow. Stopping and yielding or waiting for the next signal would typically apply to a red signal or a flashing yellow light, respectively, rather than a green arrow, which explicitly signals that it is safe to proceed.
