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

A flashing yellow light indicates that drivers should slow down and proceed with caution. This signal is meant to alert motorists that they need to be more vigilant as they approach the intersection, as there may be other vehicles, pedestrians, or changed conditions that require extra attention. It does not suggest that the light is about to change to red, nor does it indicate that speeding through the intersection is safe. Additionally, a flashing yellow does not imply that the intersection is closed; rather, it reinforces the need for careful driving. Understanding this signal helps ensure the safety of everyone on the road.
