What does a blue flag indicate and what action should you take when you see it?

• A. A blue flag indicates a faster car approaching to pass; allow it to pass and maintain a safe line
• B. A blue flag indicates rain is imminent
• C. A blue flag indicates safety car on track
• D. A blue flag indicates you must pit

Answer: (A)

A blue flag signals that a faster car is about to lap you, so your job is to yield and let it pass safely. Stay in control, avoid blocking or defending the position, and if there's a safe place to do so, move slightly to give the passing car room and let it go by. The goal is a clean, safe pass on the next clear opportunity, usually on a straight or wider section of track. Blues flags aren’t about rain, a safety car, or pit requirements, so they’re specifically about making way for a faster car.
