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

A green arrow displayed with a red light specifically indicates that drivers may proceed in the direction of the arrow, but they must do so carefully. This signal allows you to move while the red light is still present, which is a unique situation in traffic signals. It typically means that while you have the right to continue forward, you should remain vigilant for any other vehicles or pedestrians that may also be navigating the intersection.

In terms of context, this instruction is often applicable at intersections where additional conditions are present, allowing traffic to flow safely in that direction, even with a red signal showing. Understanding this rule is crucial for safe driving as it emphasizes the importance of caution and awareness, even when permitted to proceed.
