What does a green arrow showing with a red light signify?

A green arrow showing with a red light indicates that drivers are allowed to proceed in the direction of the arrow, despite the presence of the red light. This means that the traffic signal has granted priority for that specific movement, allowing vehicles to safely move through the intersection in the direction indicated by the arrow.

It's important to exercise caution while proceeding because the red light may still be in effect for other traffic at the intersection. Drivers should ensure that it is safe to continue and yield to any pedestrians or obstacles in the path of movement. This combination of signals is often used in situations where a particular lane or direction is allowed to move while other directions are halted, facilitating smoother traffic flow and reducing potential congestion.
