Roster
Each entry selects five drivers. Drivers may appear on multiple entries. The roster locks for the season; there are no trades, waivers, substitutions or roster changes after lock.
Scoring
All five drivers receive fantasy scores, but only the best three scores count for that entry in each race.
Championship ties
Free-format ties, where offered, may finish as co-champions. In paid Commissioner Best Ball, the default tiebreaker is best average finishing position of the scoring drivers across the season. Commissioners may instead allow a tie/co-champions.
