What does a green arrow traffic light indicate?

A green arrow traffic light indicates that you may proceed in the direction of the arrow. It provides a clear signal to drivers that they have the right of way and can safely move forward, typically at an intersection. This signal is used to allow traffic to flow smoothly in the indicated direction, often while opposing traffic is stopped.

In this situation, the presence of the green arrow also means that any restrictions on movement that might normally apply to a regular green light are lifted, giving you a direct path without the immediate need to yield to oncoming traffic that would be present if it were a standard green light. Drivers can therefore confidently continue their journey in the direction shown without needing to stop or prepare to yield, as would be the case with other signals.
