What does it indicate if a traffic signal is flashing yellow?

A flashing yellow traffic signal indicates that drivers should proceed with caution and reduce their speed. This signal serves as a warning that there may be potential hazards or conflicting traffic ahead, and it encourages drivers to remain vigilant. The flashing yellow light alerts drivers to be prepared for possible changes in the traffic environment, such as an intersection where cross traffic might not be regulated.

When approaching a flashing yellow signal, it is important to not come to a complete stop, as would be required at a solid red signal. However, unlike a solid yellow light, which warns that the signal is about to turn red, a flashing yellow means that drivers can continue through the intersection if it is safe, promoting a more fluid flow of traffic while still emphasizing the need to be careful. Other signals, such as a solid yellow or red light, have different requirements that necessitate stopping, which is why they do not fit the meaning of a flashing yellow light.
