FLAGGING & COMMUNICATION
These are the folks dressed in white, trackside at each turn. They use flags to inform drivers of track conditions, operate a race control radio net, and handle first response to incidents on track.
Starters handle the flags in the tower. They’re responsible for starting races, tracking progress and throwing the checkered flag at the finish.
The Pit Marshals control action in pit lane, serve as traffic cops during practice, qualifying, and race, and insure that conditions in the pits are safe, taking care of matters such as fire control.
The Paddock Marshall monitors activities in the paddock to ensure vehicles are legally parked, that race and non-race vehicles are driven safely, and watches for potential safety hazards in and around the garages.
The Grid Marshals place the cars in proper order for races and performs traffic control as cars are released to the track. They check driver safety gear and that cars permitted on track have passed inspection.
The Course Marshals maintain and deliver equipment to the corners and provide equipment and course support as needed during an event.
