What does a flashing yellow light indicate?

Answer: B — Proceed with caution

A flashing yellow light indicates that drivers should proceed with caution. This signal serves as a warning that the driver should be alert and prepared to navigate potential hazards or changes in the environment, such as pedestrians crossing or other vehicles making unexpected moves. Unlike a solid yellow light, which typically warns that the light is about to change to red, a flashing yellow light does not require drivers to come to a complete stop. Instead, it encourages them to slow down and ensure the way is clear before continuing through the intersection or area. The emphasis on caution is crucial as it promotes safety for all road users, including drivers, pedestrians, and cyclists.
