What does a black and white diagonally split flag with your car number indicate?

The black and white diagonally split flag with your car number serves as a notice regarding your driving standards. Specifically, it indicates that your driving has been reported to the Clerk of the Course for review, often due to concerns regarding safety or adherence to racing standards. This flag is a warning that further actions may be taken if improvements in behavior are not observed. It's important for drivers to understand that this flag is not a penalty itself, but rather a significant alert regarding their conduct on the track, and could lead to more serious consequences if the issues persist.

Other flags and signals have distinct meanings that differ from the one indicated by the black and white flag. For example, time penalties or issues requiring a return to the pits are communicated through their respective flags, each designed to convey specific information to the drivers about their performance or situations on the track.
