What does a flashing yellow traffic light indicate?

Answer: B — Proceed with caution

A flashing yellow traffic light indicates that drivers should proceed with caution. Stopping completely would be indicated by a solid red light, while speeding up and passing would be inappropriate as this light is typically found at intersections or in areas with potential hazards. Drivers do not automatically have the right-of-way at a flashing yellow light, as they should still yield to any oncoming traffic or pedestrians.
