A red light with a green arrow at an intersection means:

When you encounter a red light accompanied by a green arrow at an intersection, it indicates that you may proceed in the direction of the green arrow, but with caution. The presence of the red light means that typically, you would need to stop; however, the green arrow provides a specific instruction that allows you to turn in the direction it indicates. It is essential to ensure that the way is clear and safe before making the turn because other vehicles or pedestrians may still be crossing the intersection.

This scenario allows for a controlled movement despite the red light, which is not the case when only a red light is present without a green arrow. The other options imply different meanings that do not apply in this context, such as waiting for a green light without the context of the arrow or the notion that the intersection is closed, which is also inaccurate. Thus, the correct understanding of the combination of the red light and green arrow is key to safe driving.
