What does a flashing yellow traffic light indicate?

A flashing yellow traffic light serves as a warning signal to drivers. It indicates that they should proceed with caution, as there may be potential hazards ahead, or that they are approaching an area where the traffic conditions may change. It's a reminder for drivers to remain alert and to be prepared to stop if necessary.

This flashing signal is often used in situations where there might be pedestrian crossings or intersections with high traffic volumes, but not enough to warrant a full stop. It conveys the importance of vigilance while allowing for continued movement through the intersection, unlike a solid yellow light, which typically instructs drivers to prepare to stop.
