Sixty-six races have been red-flagged in Formula One, the highest class of open-wheeled auto racing defined by the Fédération Internationale de l'Automobile, motorsport's world governing body. A red flag (pictured) is shown when there has been an accident or the track conditions are poor enough to warrant the race being stopped. The flags are displayed by the marshals at various points around the circuit. Following a red flag being shown, the exit of the pit lane is closed and cars must proceed to the starting grid slowly, without overtaking. From 2005, a ten-minute warning is given before the race is resumed behind the safety car, which leads the field for a lap before it returns to the pit lane. Twenty-six of the sixty-six red-flagged Formula One races were restarted on the first lap. Thirteen races were not restarted, nine because of rain and four due to accidents involving drivers. Five races were stopped due to incidents that resulted in fatalities. (Full list...)
