What does a green arrow displayed with a red traffic light indicate?

A green arrow displayed alongside a red traffic light indicates that drivers are permitted to proceed in the direction of the arrow while other traffic is required to stop. This traffic signal configuration allows turning vehicles to move safely despite the red light for through traffic. The green arrow essentially grants a right of way to those turning in the direction indicated, often in situations where it is safe to do so without conflicting with oncoming traffic or pedestrians.

While the red traffic light instructs other lanes of traffic to halt, the green arrow provides an exception for the specific movement indicated. Understanding this signal is crucial for safe driving behavior, as it clarifies which actions are permitted and helps in managing traffic flow at intersections.
