What does a flashing yellow light indicate to drivers?

A flashing yellow light serves as a warning signal for drivers, indicating that they should proceed with caution. This signal alerts drivers to be particularly attentive to the road conditions and potential hazards, such as pedestrians crossing or vehicles that may not yield right of way in the intersection. It is not a stop signal, but rather an advisory for increased awareness and readiness to react appropriately.

In contrast to other signals, a flashing yellow light does not instruct drivers to prepare to stop immediately or increase speed, nor does it specifically indicate that the traffic light is about to turn red. Understanding the function of a flashing yellow light is crucial for safe driving practices, as it encourages drivers to remain vigilant while proceeding through an intersection with caution.
