What action is required when approaching a flashing yellow traffic light?

Answer: B — Proceeds with caution

When approaching a flashing yellow traffic light, the required action is to proceed with caution. A flashing yellow signal indicates that drivers must be alert and prepared to stop, as there may be hazards or other vehicles in the intersection. This type of signal serves as a warning rather than a stop instruction, meaning that while you do not need to come to a complete stop, you should still reduce your speed and be aware of your surroundings. This understanding is crucial in ensuring safe driving practices, as it allows for appropriate reactions to unpredictable situations, such as pedestrians crossing the road or vehicles entering the intersection. The flashing yellow light prompts drivers to be vigilant while proceeding, ensuring they can safely navigate through the area.
