What should a driver do at a red signal light with a green arrow?

When a driver encounters a red signal light accompanied by a green arrow, the correct action is to proceed with caution in the direction indicated by the arrow. This configuration means that while the overall traffic signal is red, the green arrow specifically permits movement in that direction. It is crucial for drivers to assess the intersection for any pedestrians, cyclists, or oncoming vehicles before proceeding.

This rule is designed to enhance the flow of traffic while ensuring safety for all road users. The presence of the green arrow indicates that it is safe to turn in the allowed direction, as long as the driver yields to any other traffic that may have the right of way, such as pedestrians crossing the street or vehicles traveling straight that are not affected by the turn signal.

The other choices do not align with the rules governing traffic signals. Starting without stopping could be unsafe if not accounting for other vehicles or pedestrians. Stopping before the intersection is unnecessary when the green arrow is present. Waiting for the red light to change would also contradict the purpose of the green arrow, which is to allow movement in the specified direction. Understanding this helps to ensure safe and lawful driving practices at intersections.
