What should you do at a flashing yellow light?

• A. Stop
• B. Proceed with caution
• C. Speed through
• D. Follow posted speed limit only

Answer: (B)

A flashing yellow light means you should proceed with caution. It’s signaling that you’re entering or crossing a potentially tricky area where conditions can change quickly, such as an intersection with limited visibility or pedestrians who may be about to enter the roadway. Slow down, scan for pedestrians and other vehicles, and be prepared to yield or stop if needed to avoid conflict. You don’t stop just because the light is flashing yellow, and you shouldn’t rely only on the posted speed limit if conditions require more care. If it isn’t safe to enter the intersection, you should delay until it is. This is why proceeding with caution is the appropriate action.
