What does a flashing yellow light mean?

A flashing yellow light indicates that drivers should proceed with caution. This means that while it is safe to continue driving, one must be alert to potential hazards, such as pedestrians crossing or unexpected traffic developments. It serves as a warning to be careful without requiring a complete stop, unlike a red light. The action of yielding to pedestrians and other vehicles aligns perfectly with the need for heightened awareness and cautious driving when encountering such a signal.

Stopping completely is not necessary unless the situation dictates it, and speeding up is dangerous and contrary to the purpose of the warning. Similarly, turning left is only applicable if it is safe, and that action would require different signals to instruct drivers specifically. Therefore, the primary focus of a flashing yellow light is to promote cautious movement through an intersection or area.
