White: This flag tells drivers that there is a ‘slow-moving vehicle’ on the track – so a vehicle not part of the race.
Red: The red flag is used when a session has been suspended, perhaps due to extreme weather or because there has been an accident. Yellow and Red Stripes: Denotes a slippery surface, such as oil or water getting on the track. If the flag is waved twice, it means that the track is blocked by something. This is if it’s stationary or being waved.
Yellow: This flag indicates that there is a hazard on the track up ahead, or ‘downstream’, so no overtaking is allowed. A marshal waves a yellow flag in the Formula One Grand Prix of France in 2018 (Picture: Dan Istitene/Getty Images)
