What is indicated by a flashing yellow traffic light?

Answer: B — Proceed with caution

A flashing yellow traffic light indicates that drivers should proceed with caution. This signal alerts drivers that they need to be aware of potential hazards in the roadway or upcoming intersections where they may need to yield or be prepared to stop. It serves as a warning rather than a prohibition or an order to stop, encouraging drivers to continue moving but with increased vigilance. It's important to understand that the flashing yellow light does not require a complete stop or yielding to traffic that has the right of way; instead, it conveys caution and the need for careful driving. This distinction is crucial for maintaining safety on the roads, as it helps drivers to navigate through potentially dangerous situations without unnecessarily halting traffic flow.
