What does a flashing yellow traffic signal mean?

A flashing yellow traffic signal indicates that drivers should proceed with caution. This signal is a warning, alerting drivers to be vigilant and prepared to react to potential hazards or changing conditions ahead. It does not mean to stop or speed up, but rather to drive at a safe speed while maintaining awareness of the surroundings, particularly for any pedestrians or vehicles that may be present. The flashing yellow light serves as a reminder to be on guard, ensuring that drivers can navigate through the intersection safely while still continuing through the signal.
