On lap 138, rookie Shawna Robinson and Mike Skinner tangled exiting turn 2, bringing out the fifth caution of the day. But the course of the race took a twist on lap 148 when contact between Jeff Gordon and Kevin Harvick triggered the "Big One". The pair were battling for second place, when Harvick attempted to block Gordon on the approach to turn 1, but it came too late and the 29 car first jinked left down onto the apron, before spinning back across the track and collecting a number of cars. A total of 18 cars were caught up in the wreck, the same number of cars collected in the 2001 Daytona 500's Big One. These included Matt Kenseth, Ricky Rudd, Joe Nemechek, Ken Schrader, Jeremy Mayfield, John Andretti, Bobby Hamilton, Jerry Nadeau and Earnhardt, Jr. (his third incident of the race) amongst others.
