Yellow Checkered

A term derived when the final lap in a race is completed during a full course yellow while the field is under the control of the safety car. In this instance the yellow and checkered flags are waved together and the race is declared finished with the order the same as when the full course yellow began. INDYCAR has a yellow checker rule, and NASCAR allows it if a race is shortened because of curfew or darkness, if the race is already on its final lap when the yellow must be waved, or if there is a yellow implemented after the leader crosses the overtime line (usually located on the backstretch) during a valid green-white-checkered finish once the race has restarted. In Formula One, when there is a yellow checkered, the safety car will not lead the leader to the finish line.
