A total of 26 races were restarted on the first lap, while 13 Grands Prix were not restarted, nine because of rain and four due to crashes involving drivers. Since the first World Championship Grand Prix in 1950, red flags have been shown in 85 World Championship Formula One races, with the latest one being at the 2023 São Paulo Grand Prix. Until 2015, no points were supposed to be awarded if the race could not be restarted and less than two laps had been completed, but starting in 2016 this rule was updated to 'no points if two laps or less have been completed'. If 75% of the race distance has not been completed and the race cannot be resumed, half points are awarded. If a race is unable to be resumed, 'the results will be taken at the end of the penultimate lap before the lap during which the signal to suspend the race was given'.

Previously, the race was restarted in race order from the penultimate lap before the red flag was shown. 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. Following a red flag being shown, the exit of the pit lane is closed and cars must proceed to the pit lane slowly without overtaking, lining up at the pit exit.

It involves a display of flag signals in the driver's cockpit, which alerts them to the crash. A Global Positioning System (GPS) marshalling system was introduced in 2007. The flags are displayed by the marshals at various points around the circuit. Ī red flag is shown when there has been a crash or the track conditions are poor enough to warrant the race being stopped. The results of each race are combined to determine two annual championships, one for drivers and one for constructors. The Formula One World Championship season consists of a series of races, known as Grands Prix, usually held on purpose-built circuits, and in a few cases on closed city streets. The 'formula' in the name refers to a set of rules to which all participants and vehicles must conform. Formula One, abbreviated to F1, is the highest class of open-wheeled auto racing defined by the Fédération Internationale de l'Automobile (FIA), motorsport's world governing body.
