The Graves Motorsports Yamaha semi-truck is currently parked on the side of northbound Interstate 5 just past the Fort Tejon rest stop with California Highway Patrol cars in attendance. From the appearance of the trailer, it looks like it caught fire in the area of the left wheel well. The back of the trailer was open when Roadracingworld.com’s Chris Ulrich drove past it just before 8:30 a.m., en-route to Infineon Raceway. It’s unknown at this time whether or not the incident will delay the arrival of the Graves Motorsports machines at Infineon Raceway for this weekend’s AMA Nationals.
