What does a green arrow signal at an intersection?

A green arrow at an intersection specifically indicates that drivers are permitted to proceed in the direction of the arrow. This signal indicates a clear right of way; for instance, if the arrow is pointing to the right, you can turn right without needing to stop for oncoming traffic. It clarifies the direction a vehicle is allowed to go, providing a safe way to navigate intersections, especially when turning is involved.

While other signals convey different instructions, the green arrow is unambiguous in granting permission to move forward in the indicated direction. This reduces confusion compared to other signals, such as red lights or yellow signals, which require caution or stopping. In this case, the focus is solely on the action permitted by the green arrow: moving safely and legally in the direction it points.
