Bodine will signal that car to pass him through radio contact between NASCAR and that team. The free pass car must pit with the lapped cars. In 2009, NASCAR introduced a new "Double-file restart" rule that lines the field two cars on each row on every restart, similar to the start of the race, instead of lead-lap cars on the outside and lapped cars on the inside. Also, the "wave-around" rule, similar to what is enforced in racing series sanctioned by IndyCar, was adopted to ensure the first car on the restart is the leader, and ensure there are no lapped cars ahead of the leader.

Sparks were seen emanating from Montoya's car right before its hard collision with the jet dryer trailer and left driver's side of the truck. Montoya was treated at the infield care center and released unhurt. The driver of the Chevrolet Silverado Crew Cab, Duane Barnes, was taken to a local hospital for observation and was resting comfortably. He was an employee at Michigan International Speedway, a sister track of Daytona. The tracks often share jet dryer equipment on race weekends to help in case of rain such as the case on Sunday, the original scheduled start time of the race. The entire incident took about two hours to clean up before the last 40 (later extended to 42 due to a Green-white-checkered finish) laps were able to be completed. NASCAR subsequently added the use of the second safety car (used during race start situations) to protect the last jet dryer in other safety
