What does a flashing yellow traffic signal mean?

A flashing yellow traffic signal indicates that drivers should proceed with caution. This warning signal alerts drivers to stay vigilant and prepare to react, as there may be conditions that require attention, such as hazards ahead, pedestrians, or upcoming traffic changes. It serves as a reminder to reduce speed and be prepared to stop if necessary, rather than indicating that drivers should stop entirely or that they can proceed without any concerns. This distinct signal communicates the need for careful observation and prudent driving behavior, allowing for safe navigation through intersections or areas where the signal is present.
