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

A green arrow displayed with a red traffic light indicates that you may proceed in the direction of the arrow, overriding the red signal. This means that while the red light generally requires all vehicles to stop, the green arrow specifically permits movement in the direction it points. It's a signal that there is an approved path for drivers to follow, as long as they are cautious and aware of pedestrians or other vehicles that may also be present.

This traffic signal is designed to safely facilitate certain turns or movements despite the red light, suggesting that the intersection's layout or traffic flow allows such movement without significantly affecting safety or causing conflicts with oncoming traffic.
