What does a flashing yellow traffic signal indicate?

A flashing yellow traffic signal indicates that drivers should proceed with caution. This signal serves as a warning to be aware of possible hazards ahead, such as pedestrians crossing or other vehicles making turns. It informs drivers that they should slow down and be prepared to react, but does not require them to stop as a solid yellow or red light would.

In this case, the keyword "caution" is essential; it emphasizes the need for increased awareness rather than an immediate requirement to stop. Drivers are expected to assess the situation and decide how to safely continue through the intersection.
