A red flag is shown to indicate an unscheduled stop to a race, usually for safety reasons.

The IndyCar Series is the highest class of open-wheel car racing in the United States,[1] which has been conducted under the auspices of various sanctioning bodies since 1920 after two initial attempts in 1905 and 1916. The series is self-sanctioned by its parent company, IndyCar, LLC., which began in 1996 as the Indy Racing League (IRL) and was created by then Indianapolis Motor Speedway owner Tony George.[2] The series' premier event is the Indianapolis 500, which was first held in 1911.[3][4][5]

A red flag is shown when there has been a crash or the track conditions are poor enough to warrant the race being stopped.[6][7] The flags are displayed by the marshals at various points around the circuit. An EM Marshalling System was introduced in 2022; it involves a display of flag signals in the driver's cockpit, which alerts them to the session's stoppage.[8][9] Following a red flag being shown, the exit of the pit lane is closed immediately and all cars must slow down and proceed to the pit lane without overtaking, lining up at the pit exit.[6][7] If 50% of the race distance has not been completed and the race cannot be resumed, no points are awarded.[10]

Between 1996 and 2002, when the IndyCar Series was known as the Indy Racing League, six red flags were shown in six races, two of which were not resumed. Since the name change to the IndyCar Series in 2003, red flags have been shown 46 times in 38 races, with the latest two being at the 2026 Indianapolis 500. A total of seven IndyCar Series races were not resumed, five because of weather conditions and two due to crashes involving drivers. Two races—VisionAire 500K (1999, Indy Racing League) and IZOD IndyCar World Championship (2011, IndyCar Series)—were abandoned after being red-flagged due to incidents that resulted in fatalities.[11][12] The 2023 Indianapolis 500 was red-flagged three times, more than any other race in IndyCar Series history.[13][14]
