In the ARCA Racing Series, there is a two-stage version of the rule. The rules are arranged such that the checkered flag must wave under green flag conditions.
- If the final scheduled lap of the race is under caution, when the green flag is waved for the restart attempt, there are two laps remaining in the race. If a caution comes out at any time during the first of the two laps, each subsequent restart will be a two-lap restart.
- If the furled yellow flag with a downwards-pointed finger (one lap before restart in single file formation) is given with two laps remaining in the race, and the restart is on the final scheduled lap, the green and white flag will be waved together and the race will have only one lap remaining.
- If a caution comes out during the final lap (after the white flag has been displayed), the race returns to yellow immediately. On the ensuing restart, a green and white flag are waved to signal one lap is remaining in the race. Should a yellow flag wave before the leader crosses the finish line, the race will continue under yellow until the restart, which again is one lap.
Such a format allows an unlimited number of attempts at a green flag finish. During the event at Gateway International Raceway on July 28, 2006, 22 laps (27.5 miles) were added to the 120-lap (150-mile) scheduled distance.
This version, or a similar variant with no green/white rule, is used in most short tracks.
