What does it mean when a traffic signal displays both a green arrow and a red light?

When a traffic signal displays both a green arrow and a red light, it indicates that although the red light requires drivers to stop, they are permitted to proceed in the direction indicated by the green arrow. This situation typically applies to specific turning lanes where the green arrow allows for safe turning while the red light applies to through traffic.

Drivers must still be aware of their surroundings and ensure it is safe to turn in that direction, adhering to any other traffic rules or signals. For instance, if turning left at an intersection with oncoming traffic, drivers need to ensure that they yield to these vehicles. Thus, while the green arrow provides permission to turn, the red light remains a crucial signal that drivers must recognize, especially regarding other traffic movements.
