What does a green arrow mean at an intersection?

A green arrow at an intersection indicates that drivers can proceed in the direction of the arrow with a clear signal to go. This means that the lane or direction indicated by the green arrow is open for movement, allowing vehicles to turn or move straight without the need to stop or yield to other traffic. Typically, the presence of a green arrow means that the traffic light is either in the process of changing or is allowing for unrestricted movement, distinguishing it from other signals that might require caution, such as yellow or red lights. This clear directive is vital for maintaining safety and organization at busy intersections.
