What does a flashing yellow traffic light mean?

A flashing yellow traffic light signifies that drivers should proceed with caution. This indication alerts drivers to be vigilant and aware of their surroundings as they approach the intersection or area controlled by the light. It suggests that other traffic conditions may be present that require careful attention, like pedestrians crossing, other vehicles, or changes in traffic patterns.

In contrast to a solid yellow light, which advises drivers to prepare to stop, a flashing yellow encourages continuation of the journey while maintaining a careful watch for potential hazards. It does not imply that vehicles need to stop, yield rights of way, or accelerate in any way, which is why other options do not fit the meaning conveyed by a flashing yellow signal.
