What does a flashing red light at an intersection mean?

Answer: B — Treat it like a stop sign

A flashing red light at an intersection indicates that drivers must come to a complete stop, similar to a stop sign. This signal means that you should yield the right of way to any vehicles or pedestrians that may be crossing the intersection before proceeding. It's crucial for ensuring safety, as it alerts drivers to potential hazards or cross traffic requiring attention. When approaching a flashing red light, it's important to fully stop, check for traffic, and then proceed when it is safe to do so. This practice reinforces the rules of road safety and emphasizes the need for full awareness of surrounding conditions, which is essential in preventing accidents at busy intersections.
