What does a green arrow signify at an intersection?

A green arrow at an intersection specifically indicates that drivers are allowed to proceed in the direction of the arrow, provided it is safe to do so. This signal is used to provide clear guidance to drivers, indicating that they have the right of way to turn or move forward in the direction shown by the arrow. It typically appears in conjunction with a red light for other lanes of traffic, meaning that while you can go, opposing traffic must remain stopped.

Understanding the implications of a green arrow helps drivers recognize when they can safely proceed without waiting for a further signal, which enhances traffic flow and reduces confusion at intersections. The context of other potential answers reinforces the importance of understanding the traffic signals: stopping or yielding are not actions associated with a green arrow, which is designed instead to provide affirmative instruction to move ahead when it is safe.
