Crashnet > Guide Index > 3. Start, Restart & Finish

• Clutch start: used primarily in Hot Rod formulas, cars start from standstill. Drivers usually have car in gear, resting the clutch until green flag is dropped, hence name.
• Rolling start: cars roll around track, often with a pace car ahead, before start. When pace car exits and green flag then drops, cars accelerate to full speed. Note that not all promotions or tracks use pace cars, relying on lead grid cars to keep pace.
• False start: Where one or more drivers accelerates to racing speed before the green flag drops, giving that driver or drivers unfair advantage. Race will be stopped and/or drivers penalised at stewards' or starters' discretion.
• Full restart: Occurs when race is stopped due to false start or racing incident where race has yet to reach a point where it is deemed to be sufficiently run for good racing to have occurred. Often this is defined as a quarter of the total race laps scheduled. Cars will assume grid positions and race restarted. Any laps or positions from aborted race segment are counted as void.
• Ordered or position restart: Occurs when race is stopped due to racing incident where race has reached a point where it is deemed to sufficiently run for good racing to have occurred, often defined as a quarter of the completed laps up to three quarters of the completed laps. Cars assume position in single file according to position in race at last completed lap, race will restart and continue for remainder of scheduled laps.
• Declared result: If the race has reached three quarters of its schedule and has been stopped, then the result is declared based on the positions at the last completed lap. No further racing will take place, the race having been declared over.
