During a race, it is displayed at the end of a caution period or a temporary delay to indicate that the race is restarting. The solid green flag is usually displayed by the starter to indicate the start of a race. The green flag signals a clear track to race on and the start of the race. In addition, the green, yellow, and red flags described below may be augmented or replaced by lights at various points around the circuit. Status flags are used to inform all drivers of the general status of the course during a race.

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.
