What does the green arrow mean at an intersection?

A green arrow at an intersection serves as a clear signal indicating that drivers are permitted to proceed in the direction of the arrow. This sign means that the path is clear for vehicles to move forward, allowing for a safe and unimpeded transition through the intersection. It typically implies that other road users or traffic from conflicting directions are either stopped or yielding, ensuring that the driver can confidently navigate without the need to stop or yield. This signal helps to facilitate smoother traffic flow and enhances safety by providing unmistakable guidance to drivers about their right of way in that direction.
