What does a green arrow mean?

A green arrow indicates that you may proceed in the direction the arrow is pointing. It signifies that you have the right-of-way to go in that direction while other vehicles should yield if they are in conflict with your movement. This traffic signal typically appears at intersections and is used to guide drivers, making it clear that it is safe to continue.

The function of a green arrow is to provide clear guidance and facilitate flow in a specific direction, reducing ambiguity for drivers. Understanding this signal is crucial for navigating intersections safely and efficiently.

The other options suggest actions that are not appropriate when a green arrow is displayed: stopping is unnecessary as the green arrow indicates permission to proceed, yielding to oncoming traffic is not required since the signal provides a clear right-of-way, and changing lanes immediately is not relevant to the meaning of a green arrow.
