What does a green arrow signal to drivers?

A green arrow signals to drivers that they can proceed in the direction the arrow is pointing, often allowing them to make a turn while oncoming traffic is halted. This indicates a clear right of way, meaning drivers can move through the intersection confidently without the need to yield to other vehicles or pedestrians, as long as they follow other traffic signals and rules. The purpose of the green arrow is to facilitate smooth traffic flow, especially in situations where turns may otherwise be complicated by oncoming traffic. This clear instruction helps ensure safety and efficiency at intersections.
