What does a flashing yellow light mean?
Answer: B — Proceed with caution
A flashing yellow light indicates caution and that you should slow down and be prepared to stop, if necessary. Option A, coming to a complete stop, is incorrect because it is reserved for a solid yellow light. Option C, speeding up, is incorrect because it goes against the cautionary nature of the flashing yellow light. Option D, turning left, is incorrect because it specifically states "turn left," while a flashing yellow light applies to all directions of travel. Therefore, the best option is to proceed with caution, allowing you to safely navigate the intersection and adjust to changing conditions.
