FIA-sanctioned championship flags are the most commonly used internationally (outside of North America) as they cover championships such as Formula 1, the FIA World Endurance Championship and WTCC, and are adopted (and sometimes adapted) by many more motorsport governing bodies across the world such as, for example, the MSA. For example, the chequered flag is commonly used across all of motorsport to signify the end of a session (practice, qualifying, or race), while the penalty flags differ from series to series. While there is no universal system of racing flags across all of motorsports, most series have standardized them, with some flags carrying over between series. Alternatively, some race tracks employ lights to supplement the primary flag at the start/finish line. Track marshals are also stationed at observation posts along the race track in order to communicate both local and course-wide conditions to drivers.
Typically, the starter, sometimes the grand marshal of a race, waves the flags atop a flag stand near the start/finish line. Racing flags are traditionally used in auto racing and similar motorsports to indicate track conditions and to communicate important messages to drivers.
