The procedure was used in NASCAR racing series when the pace car was deployed as a result of an on-track emergency such as a crash or rain.
In addition, if the yellow came out on the final lap, the race would continue until the cars crossed the finish line.
[1] This especially showed during the 2003 Sylvania 300 at Loudon when Dale Jarrett had stopped in the middle of the track at the start finish line while the drivers were racing back to the flag.
Robby Gordon kept charging, and passed Harvick in the keyhole turn, taking the lead before they crossed the start/finish line.
He was subjected to considerable controversy; some ridiculed his action while others considered the complaints hypocritical or "sour grapes" by the losers.
Jeff Gordon, however, sped past all three and beat them back to the start-finish line, officially taking the lead.
However, instead of Gordon keeping the lead, NASCAR scored Kenseth in front, while Busch and Rudd were allowed to make up a lap.
[4] After racing back to the yellow was eliminated, a special exception to this practice was implemented and allowed, by the beneficiary rule where the highest-placed car not on the lead lap is given a lap back if a caution occurs Though racing to the yellow was officially banned in 2003, there have been numerous races that finished under green despite a last-lap crash as the caution did not occur, notably the 2004 Winn Dixie 250 at Daytona won by Mike Wallace[5] the 2015 Alert Today Florida 300 won by Ryan Reed,[6] the 2007 Daytona 500, the 2019 1000Bulbs.com 500, and the 2020 Daytona 500.
