On March 16, 1997, Nemechek was running a Truck race at Homestead-Miami Speedway when with 25 laps to go, he suddenly lost control of his truck and slammed into the first-turn wall, driver's-side first, suffering major head injuries. He was extricated and transported to a nearby hospital, where he clung to life over the next five days before finally succumbing on March 21, nine days after his 27th birthday.

When he was not racing, Nemechek served as the front-tire changer on Joe's pit crew, and was on Joe's 1992 NASCAR Busch Series championship-winning team. He would begin attempting NASCAR races himself, and ran one Busch race at IRP in 1994. He finished 30th after his No. 89 Chevrolet suffered an engine failure. The following season, he began racing in the new Craftsman Truck Series, driving at first for Redding Motorsports, and then for his brother's NEMCO Motorsports. In the first year of competition, Nemechek ran 16 races and had two top-ten finishes. He followed that up with two more top-tens in 1996 and a thirteenth-place finish in points, running a single truck he built himself titled the War Wagon under his own team, Chek Racing.
