Flag Summary
Here is the whole flag vocabulary in one place — a quick reference you can scan before or during any race.
| Flag | Meaning |
|---|---|
| Green | All clear — racing resumes |
| Single yellow | Danger ahead, slow, no overtaking |
| Double yellow | Be ready to stop, track blocked |
| Red | Session stopped |
| Blue | Let the lapping car past |
| Yellow & red stripes | Slippery surface (oil, water, debris) |
| White | Slow vehicle on track ahead |
| Black & white | Warning for conduct |
| Black/orange circle | Mechanical problem — pit now |
| Black | Disqualified |
| Chequered | Session over |
Behind every one of these signals is a network of marshals — the volunteers stationed at posts around the circuit who watch their stretch of track, wave the flags, clear debris, and reach a stricken car in seconds. The dashboard lights are the modern backup, but the flags themselves remain the official word, and a driver is responsible for obeying them whether they saw the marshal or the light.
Key takeaways
- Yellows and blue are the everyday flags; the rest are exceptions.
- Yellow-and-red stripes warn of a slippery surface; white warns of a slow vehicle.
- Marshals wave the official flags; dashboard lights are the backup.
- Keep this table handy as a one-glance reference.
