What does a flashing yellow light mean?

Answer: B — Proceed with caution

A flashing yellow light indicates that drivers should proceed with caution. This signal is used to alert drivers to potential hazards or situations that may require careful attention, such as an upcoming intersection or a shared roadway with pedestrians or cyclists. It does not require a complete stop, as would be indicated by a solid yellow or red light. Instead, it serves as a reminder to be vigilant and ready to react appropriately to ensure safety. This is particularly important in areas where conditions may change or where there may be increased risks, emphasizing the need for awareness while continuing through the intersection or area. Understanding this can help drivers better navigate situations that require additional care without unnecessarily halting traffic flow.
