In 2005, he started his Truck series season with a bizarre finish. He led the final laps of the 2005 Dodge Dealers 250 at Daytona International Speedway when Jimmy Spencer got by with a few laps left and the white flag flew just before a crash occurred in turn 1. During the accident, Hamilton passed Spencer for the lead. Due to the scoring loop rules before the accident it was initially believed that Spencer won. Spencer drove to victory circle but not long afterwards it was determined that Hamilton won; Hamilton was at the final scoring loop as he was in the lead.
