Driver ownership is exclusive. Lineups carry forward automatically. Start/Garage changes and trades lock one hour before the scheduled race start.
Draft
Free leagues use a snake draft. Paid Commissioners may select Snake, Linear or Auction where supported.
Free agency and trades
Free leagues use standard waivers. Paid Commissioners may configure supported waiver/free-agent options. Trades are allowed in Free and paid leagues. Free trades require Commissioner approval; paid leagues may use automatic approval or Commissioner approval.
IR
A driver confirmed out for one or more races may be placed on IR. Paid Commissioners decide whether suspended drivers are IR-eligible. When a driver returns, the roster must return to its normal active limit before activation.
Playoffs
Free leagues begin their fantasy playoffs with NASCAR's championship/playoff portion of the season, with the top 80% of teams qualifying. Paid Commissioners may choose NASCAR-style playoffs or full-season points and may configure the playoff field.
Late withdrawals
If a driver withdraws or does not start after the one-hour lineup lock, the locked choice remains. Free leagues do not receive a post-lock substitute. Paid Commissioners may make documented exceptional corrections using audited Commissioner tools.
