What does a flashing red traffic light mean?

Answer: B — Treat it like a stop sign

A flashing red traffic light indicates that drivers must come to a complete stop, just as they would at a stop sign, before proceeding. It’s crucial for maintaining safety at intersections, as it alerts drivers to potential hazards, requiring them to pause and ensure the way is clear before continuing. While the option to proceed with caution may seem reasonable in some cases, the correct interpretation of a flashing red light is more stringent, requiring a full stop first. This rule helps prevent accidents and promotes orderly traffic flow by ensuring that each vehicle acknowledges their stop and yields to any oncoming traffic or pedestrians, which is why treating it like a stop sign is the accurate response to this situation.
