Darrell Waltrip came back from a penalty to win the NASCAR GN ‘Virginia 500’ at Martinsville Speedway, Virginia, US as a new tire rule wreaked havoc. In an effort to cut costs, NASCAR imposed a 2 lap penalty for tire changes under caution. Leader Waltrip pitted before the green fell at the end of the day’s 3rd caution, incurring a 2 lap penalty. The rule stated cars must take the green before pitting. “I just messed up” said Waltrip. Buddy Baker fell from contention after his right front tire went flat during a red for rain. When the race resumed under caution, Baker pitted and received a 2 lap penalty. On lap 342, Bobby Allison’s efforts to stretch his tires ended when he blew a tire and hit the wall.
