What does a flashing yellow traffic light signal to drivers?

A flashing yellow traffic light indicates that drivers should proceed with caution and be prepared to stop if necessary. This signal serves as a warning that the intersection or road ahead may pose potential risks, such as reduced visibility, pedestrians, or vehicles unexpectedly entering the intersection. Unlike a steady yellow light which signals drivers to prepare to stop before the light changes to red, a flashing yellow light allows drivers to continue moving while maintaining a heightened level of awareness.

This understanding emphasizes the need for drivers to remain attentive and to evaluate the intersection for safety. There may be situations where caution is critical, such as when approaching a crosswalk or when traffic conditions are unpredictable. Therefore, being prepared to make quick decisions, including stopping if needed, is vital when encountering a flashing yellow light.
