[Pantone Value] 298C [Meaning] At any time, a stationary light blue flag may be shown to a driver at the pit lane exit to warn him that cars are approaching on the track. During practice, a light blue flag waved on the track notifies a driver that a faster car is approaching and that he must move aside. During a race, a light blue flag waved on the track warns the driver that he is about to be lapped by a faster car and must not intentionally impede their progress, such as blocking a passing manoeuver. A driver may incur penalties if he ignores three successive blue flags. [Description]
