What does it mean if a traffic light is flashing yellow?

A flashing yellow traffic light indicates that drivers should proceed with caution. This signaling means that while there is no requirement to stop, drivers must be prepared to slow down and yield to any oncoming traffic or pedestrians in the intersection. It's a way of alerting drivers that they should be attentive to their surroundings as they approach.

Other options are not appropriate in this context. A stop before proceeding would apply to a solid red light, while turning around or encountering a stop sign ahead would not be relevant to the situation presented by a flashing yellow light. The flashing yellow serves as a warning to remain vigilant without the obligation to halt completely, allowing for safe passage through the intersection while maintaining awareness for any potential hazards.
