Green-white-checker finish
Encyclopedia
The green-white-checker finish is a rule implemented into many levels of automobile racing in the United States. When the race would otherwise end during a yellow-flag caution condition (during which no competition may take place, including no passing), this rule gives the field an attempt to finish the race under a green-flag, racing condition. Instead of ending the race when the stated distance has been covered, it continues until the green flag is given (signalling the end of the caution condition), at which time the drivers resume the race with two laps remaining, regardless of the actual number of laps covered to that point. They then get the white flag, signaling the final lap, and then take the checkered flag, signaling the end of the race.

Depending on the series' sanctioning body, there may be a number of possible variants cited in the application of this rule.

 Re/Max 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.

 was prohibited in the series.)

However, if on the restart, there will be just one scheduled lap remaining, there is a green and white flag restart for the lap. That rule was implemented a few times.

In the middle of the 1998 season, however, a rule change by NASCAR affected the rule; if the yellow flag comes out during the final lap of the race, the trucks would race to the finish. (In the middle of the 1998 season, as NASCAR eliminated the two-segment races, NASCAR permitted the trucks to race to the caution.) That rule was eliminated in September 2003 as a result of the ban on racing back to the caution.

, multiple green-white-checkered restarts resulted in a 160-lap race going 14 additional laps. After that race, the rule was changed to standardise the rule with NASCAR's other national series, which also adopted the rule.

Sprint Cup and Nationwide Series (July 25, 2004-present)

In the late 1990s, NASCAR's other two national series, the Sprint Cup and Nationwide Series, had set a loose precedent that allowed for a red flag to be displayed during a late-race caution flag. At the time, races on the other two national circuits were prohibited from being extended beyond the advertised distance. The action would temporarily halt the race, allowing safety crews to clear the track, and allow for a full restart, without the field having burned up the remaining laps under yellow. Initially, the rule was used only on short tracks, but eventually spread to all races. The implementation, however, was widely inconsistent, and inevitably would lead to controversy.

At the 2002 Pepsi 400, a late-race caution came out, and participants and spectators expected a red flag. NASCAR chose not to halt the race, citing too few laps remaining, and fans pelted the circuit with cans and other debris as it finished under yellow. The decision not to go back to green was based on two similar situations at restrictor plate tracks. In the 1993

For 2003 and 2004, the red flag rules were clarified somewhat to standardise the use, with a specific lap, usually five laps remaining, being the lap designated as the "last red flag lap."

 and Jeff Hammond.

In the wake of the controversies, in mid-July 2004, all three touring series, adopted a new, revised green-white-checkered rule. The revised format handles late-race cautions in a standardized manner.

Caution after the white flag has been shown

The race is over. The field is frozen at the moment of the yellow flag, and the scoring is official as cars cross the finish line. The second point is a critical one: cars must be able to complete the final lap under their own power. The 2007 LifeLock 400 was somewhat controversial for this reason, as Greg Biffle ran out of fuel while under caution. Biffle was not able to maintain pace car speed, but he did manage to coast across the finish line and was awarded the win despite being passed by some cars while under caution.

There is a notable exception to this rule. If there is an incident during the final lap behind the leaders, and the run to the finish line is clear for the leaders, NASCAR may delay the caution until the checkered flag is shown, allowing the leaders to race for the win. In such cases track safety workers may arrive at the scene of the incident. This exception was used during the 2007 Daytona 500

.

Caution with two laps remaining

If a caution period starts, or continues, any time with two laps remaining in the scheduled distance, NASCAR allows at least one attempt to finish the race under green flag conditions. From 2004 through 2009, one attempt was allowed; starting in 2010, up to three attempts can be made. This began with the 2010 Budweiser Shootout. With two laps to go, during an official green-white checkered, Jeff Gordon got into the back of Greg Biffle, creating a multi-car wreck and giving the win to Kevin Harvick.

When it is determined that the track is clear for racing, the green flag is shown, indicating the restart. As the leader completes the first lap, the white flag is shown, signaling the final lap. As the leader completes the second lap, the checkered flag is shown, signaling the conclusion of the race.

If the caution flag is shown during the first of the two laps, the field is frozen as it would be during a regular race caution, and a second green-white-checker attempt will be made, up to a maximum of three attempts. If the caution flag after the white flag is shown during the first two attempts, or during the third attempt at any time, the race is over. The field is frozen at the moment of the yellow flag, and the scoring is official as cars cross the finish line.

In the event of a race ending due to caution, video evidence is used in addition to scoring loops to determine the official order of finish.

A green-white-checkered finish will extend the race beyond its advertised distance, and competitors were not allowed to pit for fuel without losing positions. Teams are responsible for considering the extended distance in their fuel strategies. However, if the cleanup is expected to take considerable time, NASCAR may red flag the race with the cars on the track, so that cars don't consume all their fuel under 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.
