What does a flashing yellow light mean?

Answer: B — Proceed with caution

A flashing yellow light indicates that drivers should proceed with caution. It serves as a warning to be alert and slow down, as there may be potential hazards or intersections ahead. This signal does not require a complete stop, but it emphasizes the need for increased awareness of surrounding traffic and conditions. Drivers should be prepared to react to any unexpected situations, such as pedestrians crossing or vehicles making sudden maneuvers. Unlike a solid green light which suggests that traffic can proceed at normal speed, a flashing yellow light advises a careful approach to ensure safety without completely halting movement.
