What does it mean if a traffic light is flashing yellow?

Answer: B — Proceed with caution

A flashing yellow light indicates that drivers should proceed with caution. It serves as a warning to alert drivers to potential hazards or to slow down in areas where there may be additional traffic or pedestrians. Unlike a solid yellow light, which indicates that the light is about to change to red, a flashing yellow provides more of a guideline for safe driving. Drivers are encouraged to assess the situation ahead and be aware of what may be happening around them, ensuring they can react appropriately. This could mean slowing down further, yielding to other vehicles or pedestrians as necessary, and navigating the intersection safely. Understanding this signal helps to promote safety on the roads by encouraging vigilant and cautious driving behavior.
