What does a flashing yellow traffic light mean?

Answer: B — Proceed with caution

A flashing yellow traffic light indicates that drivers should proceed with caution. This signal serves as a warning that there may be conditions requiring extra attention. It suggests that while it is safe to move forward, drivers should be vigilant and prepared to react to any unforeseen obstacles or changes in traffic behavior. In practice, encountering a flashing yellow light means you should slow down and be aware of potential hazards, such as pedestrians crossing or vehicles displaying erratic behavior. It's critical to maintain awareness of your surroundings and be ready to yield if necessary, but you are not required to stop unless there are specific circumstances that make it unsafe to continue.
