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. It warns of a potential hazard or a change in the traffic pattern ahead. This signal asks drivers to be aware of their surroundings and to reduce their speed as they approach the intersection or the area affected by the flashing light. This is crucial because while it does not require a complete stop, it emphasizes the need for attentiveness and readiness to react to any unexpected conditions that may arise, such as pedestrians crossing or other drivers behaving unpredictably. In contrast, stop signals or solid lights would require more definitive actions from the driver. The flashing yellow serves as a reminder to stay alert without requiring halting completely, which distinguishes it from other traffic signals that have different implications regarding vehicle movement.
