Kyle Petty was sporting a No. 45 baseball cap with a black line through the 45 on Saturday. He said that’s in honor of his son, Adam. who drove the No. 45 before he was killed in a Busch Series accident during practice in May 2000 at New Hampshire Motor Speedway.
“My grandfather (Lee Petty) drove the No. 42, King (Richard) drove the No. 43, I drove the No. 44 and Adam drove 45,” Kyle Petty said. “I always said I’m just filling in for Adam in the 45. The 45 with the mark in it is my tribute to acknowledge that Adam drove the No. 45 car, not Kyle Petty.”
