Barnes apparently missed a driveway in the smoke and drove his truck into a ditch. The trailer he was pulling blocked the southbound lane of County Road 315, about three miles north of State Road 100.
A small two-door hatchback, driven by 51-year-old Ellen Wilder of Keystone Heights, collided with the trailer.
While Barnes was on the phone with E911, a small pickup stopped just short of the hatchback.
A 1-ton dual-rear wheeled truck then struck the small pick-up, pushing it into the hatchback, which in turn hit the trailer again.
The force of the crash caused the small pickup to spin counter-clockwise and pin Barnes between it and his own truck.
