**Any Black Flag that isn't served within 3 laps will result in a Disqualification.

PLAYOFFS: The Chase field will consist of 16 drivers for the 10-race Chase. The 16 drivers are chosen primarily on wins during the "regular season", if fewer than 16 drivers win races, the remaining field is filled on the basis of regular season points. These drivers compete against each other while racing in the standard field of 43 cars. The driver with the most points after the final 10 races is declared the champion.

The playoff system institutes three "cuts" where drivers are eliminated from title contention as the Chase progresses. In each cut the bottom four drivers are eliminated from title contention after the third race after a cut. After the first cut (Dover) in what is called the "Round of 16", the field is reduced to 12. The bottom four winless drivers keep their points after the first cut, while the remaining 12 Chase drivers' points are reset to 3,000 points. After three more races, the cut line eliminates the bottom four winless drivers after the sixth Chase race (Talladega) in the "Round of 12", reducing the size of the field another 33%. Drivers who miss the second cut have their points reset to their score at the end of the first cut, plus the combined points accumulated in the three races in the "Round of 12." Those who continue have their points all reset to 4,000. Then the "Round of 8" involves axing 50% of the Chase grid with the final cut, cutting the new bottom four drivers after the penultimate race at Phoenix, leaving the top four drivers to have their point totals reset to 5,000 so that they are tied for the final race at Homestead-Miami for the title run. The drivers who miss the cut after this round have their score reset to the score at the end of the first cut, plus total points accumulated in the six previous races. Of these four drivers who make this cut, the driver with the best absolute finish (no bonus points are involved) at Homestead is then crowned the season champion.

Under this system, any Chase driver who wins a race during a playoff round is automatically guaranteed a spot in the next round. Up to three drivers thus can advance to the next round of the Chase through race wins, regardless of their actual points position after the final (third) race in that round. The remaining drivers to advance is determined by points.

The Kevin Harvick Rule – Fifth Place

Fifth place in the season-ending standings will be determined amongst the Chase drivers eliminated in each of the Chase rounds during the final races.

First Round Elimination

Drivers eliminated in the first round will retain their Chase score (for example, a driver with one win during the season eliminated after scoring 75 points during the first round will score 2,080 points) and start the fourth race the same score after the first three races, and will accumulate points for the remainder of the season.

Missed the Second or Third Cut

Drivers eliminated in the second or third round will have their score reverted to the score at the end of the first round, then their individual race scores for the three (eliminated in the second round) or six races (eliminated in the third round), respectively, before their elimination from the championship contention will be combined with the score after the third race of the first round for the driver's total score.

For the Final Race

After ten races, the drivers positions 5–16 will be determined by the total number of points accumulated in the ten races (bonus points will apply), without the points resets of the second or third rounds, added to the driver's base Chase score with bonuses added. In the final race, unlike the four championship contenders who cannot score bonus points (the winner is determined by the driver who finished the best of those four), both non-playoff and playoff drivers eliminated from the championship are eligible to score all bonus points, so drivers who are contending for positions 5-16 will compete solely against each other.

POINTS: There are only steps of 1 point between all ranks, beginning with 1 point for rank 40. The winner automatically receives an additional 3-point bonus for winning a race and the 1 point bonus for leading the final lap. A driver receives 44 points at minimum for winning a race. If a driver leads the most laps, wins both stages and the race, they receive a maximum amount of 65 points.

The top 10 drivers at the end of the first two stages each race earn additional bonus points towards the championship, 10 points for the first place car down to 1 point for the 10th place car. At the end of the race, the normal championship point scheme is used to award points to the entire field. Additionally, "playoff points" are awarded during the regular season for winning stages, winning races, and finishing the regular season in the top 16 on the championship points standings. 1 playoff point for the winner of a stage, 5 playoff points plus an automatic berth into the round of 16 for the race winner. (In case there are more than 16 race winners in the season, then the top 16 in race wins move on). Also, more bonus points for Top-10 in points standings at the end of the regular season: 1st place in regular season points earns 15 playoff bonus points in addition to the points earned with race or stage wins; 2nd place earns 10 playoff points, 3rd place: 8, 4th place: 7, 5th place: 6, 6th place: 5, 7th place: 4, 8th place: 3, 9th place: 2, and 10th place: 1. Playoff points are also awarded in each playoff race, except the final race, for those drivers still competing for the championship, for winning stages and winning races. If a driver qualifies for the championship, these playoff points will be added into their point totals after the resets for the first 3 rounds (Round of 16, Round of 12, Round of 8). For the Round of 4, (final race) there are no bonus points involved and the highest finishing driver of the 4 is declared the champion. This means a driver can have less regular season points than another driver, but be seeded higher due to more wins.
