High Quality Content by WIKIPEDIA articles! 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.
