What does a flashing red traffic light mean?

A flashing red traffic light indicates that drivers must treat it as if it were a stop sign. This means that you should come to a complete stop at the intersection, check for any oncoming traffic, pedestrians, or other road users, and only proceed when it is safe to do so. This rule ensures that safety is prioritized at intersections where visibility may be limited, or where traffic patterns require increased caution.

The other options do not accurately reflect the meaning of a flashing red light. A flashing red light specifically requires a complete stop, which is more stringent than simply yielding to traffic or proceeding with caution. Therefore, understanding the protocol associated with flashing red lights is crucial for safe driving practices at intersections.
