During the 2002 Infiniti Pro Series (now Indy Lights) race at the track, Jason Priestley suffered a concussion and fractures to his thoracic spine and feet, becoming the first major injury to occur at the speedway. Three years later, Carroll began his efforts to receive a Nextel Cup Series event at the track. While trying to do so, Kentucky Speedway filed an anti-trust lawsuit against NASCAR and the International Speedway Corporation (ISC). The reason for the lawsuit was the claim that both companies violated federal antitrust laws because of restricting the awarding of Nextel Cup Series events. The lawsuit continued for three years before concluding in January 2008 with Judge William O. Bertelsman dismissing the trial with ISC and NASCAR winning the lawsuit. Following the dismissal, Judge Bertelsman commented, "After careful consideration and a thorough review of the record, and granting Kentucky Speedway the benefit of the doubt on all reasonable inferences therefrom, the court concludes that Speedway has failed to make out its case."
