As a publicly traded company, Dover Motorsports must make various documents available to the public, including sanction agreements with NASCAR for its races in 2021 at Dover International Speedway and Nashville Superspeedway.

The 2020 season marks the end of the five-year agreements NASCAR had with tracks, so 2021 provides a look at any changes to the sanctioning agreements.

In the sanctioning agreements for races at Dover and Nashville in 2021 is a minimum attendance clause.

It states: "Promoter will use best efforts to ensure a minimum spectator attendance in grandstand seating during the NASCAR Cup Race portion of the Competition of at least seventy percent (70%) of Capacity of the Facility."

That isn?t 70% of all of a track?s seats but 70% of all seats that are available and not covered by signs or banners.
