Changes

The only road course on the 2017 schedule, Road America, was taken out for 2018. The races at Winchester Speedway and Kentucky Speedway were also taken off the schedule.[18] The races at Elko Speedway and Lucas Oil Raceway shifted significantly.[19] Elko moved to the middle of July because the first Pocono date was moved to the weekend that Elko had in 2017, and Lucas Oil moved to September because the NASCAR Indianapolis weekend was moved to September.
