Green-white-checker Finish - Other Uses

Other Uses

British Superbike Championship motorcycle racing uses a similar rule after two-thirds of the race has been completed. After two-thirds of the race laps (rounded down) have been completed, if a caution is called, the race will be extended by three laps.

For example, in an 18-lap race, the caution is waved on the 14th lap (two-thirds is 12 laps). The caution period lasts three laps, with the safety car coming in at the end of the 16th lap, effectively calling the restart on Lap 17. which would be two laps remaining. However, British Superbike rules state once two-thirds of the race distance is passed, the first three laps of a caution "do not count as race laps," thereby implementing a green-white-checkered style rule where the three laps are added to the scheduled race distance, thereby making the race a total of 21 laps.
