What does a flashing red traffic light mean?

A flashing red traffic light indicates that drivers must come to a complete stop, just like at a stop sign. Once stopped, the driver must then check for any oncoming traffic, pedestrians, or other hazards and proceed only when it is safe to do so. This traffic signal is used to alert drivers of a potentially dangerous situation at an intersection or to control traffic flow at specific locations.

The other options suggest different actions that do not align with the definitive requirement of a flashing red light. For example, proceeding with caution or being prepared to stop does not emphasize the necessity of a complete stop before proceeding. Yielding to pedestrians is important at intersections, but it does not specifically address the actions required by a flashing red light.
