Black Flag with White Cross

A Black Flag with White Cross is a serious penalty flag in motorsport that indicates a driver is no longer being scored in the race, typically for ignoring previous flag instructions.

This flag is most commonly displayed when a driver has failed to obey a regular black flag, which orders them to pit immediately. In NASCAR, drivers usually have five laps to respond to a black flag before receiving this more severe penalty. Once shown the Black Flag with White Cross, a driver must pit to address the original issue before they can be scored again.

In some racing series like IndyCar, this flag represents a complete disqualification. Ignoring this flag can result in additional post-race penalties including fines or suspensions, making it one of the most serious signals in motorsport.
