Use of flags[edit]
Main article: Racing flags
In many types of auto races, particularly those held on closed courses, flags are displayed to indicate the general status of the track and to communicate instructions to competitors. While individual series have different rules, and the flags have changed from the first years (e.g., red used to start a race), these are generally accepted.
| Flag | Displayed from start tower | Displayed from observation post |
|---|---|---|
 | The session has started or resumed after a full course caution or stop. | End of hazardous section of track. |
 | Full course caution condition for ovals. On road courses, it means a local area of caution. Depending on the type of racing, either two yellow flags will be used for a full course caution or a sign with 'SC' (Safety car) will be used as the field follows the pace/safety car on track and no cars may pass. | Local caution condition —no cars may pass at the particular corner where being displayed. When Stationary indicates hazard off-course, when Waving indicates hazard on-course. |
 | Debris, fluid, or other hazard on the track surface. | Debris, fluid, or other hazard on the track surface. |
