What does a flashing yellow traffic light indicate?

A flashing yellow traffic light indicates that drivers should proceed with caution. This signal alerts drivers to be aware of potential hazards or changing traffic conditions ahead. It does not mean to come to a complete stop; instead, drivers should slow down and be prepared to yield to other vehicles or pedestrians as necessary. The emphasis on caution is crucial, as it signals that the driver should be vigilant and ready to react to unexpected situations while continuing through the intersection or area.

In comparison, a solid green light directs drivers to proceed without hesitation, and a solid red light requires a complete stop. Yielding to pedestrians is important at all intersections, regardless of the traffic signals, but it is not the primary function indicated by a flashing yellow light. Lastly, increasing speed is not appropriate when confronted with a flashing yellow light, as it calls for cautious behavior rather than acceleration.
