On the start, Kurt Busch led the field to the green flag. On the same lap, Jeff Gordon passed Kurt Busch for the lead. On lap 2, Kevin Conway collided with the wall; to cause the first caution. On lap 5, Gordon led the field to the green flag. After the restart, the field became spread out, but on lap 45, Mike Bliss collided with the wall to bring out the second caution. The restart happened on lap 52, with Gordon leading. One lap later, Greg Biffle passed Gordon, and the third caution came out. The third caution came out because the caution lights did not turn off. On the lap 56 restart, Biffle led the field to the green flag, but one lap later, Gordon reclaimed the lead.[11]
