What does a flashing red light signify?

A flashing red light functions similarly to a stop sign, indicating that a driver must come to a complete stop. This signal is used to alert drivers that they need to halt their vehicle and ensure the intersection is clear of cross traffic or pedestrians before proceeding safely. It emphasizes the importance of stopping fully and assessing the situation, rather than merely slowing down or proceeding with caution, which could lead to unsafe conditions. Understanding this rule is crucial for ensuring safety at intersections, particularly in scenarios where visibility is limited or where other vehicles and pedestrians may be present.
