Abstract: Employee #1 was sitting in state highway truck #8718 while four coworkers were repairing highway guardrails. A semi tractor hit a small object in the road and went out of control. The tractor hit a concrete abutment on the west side of the bridge, reared across the highway and hit the east side of the bridge, and came back across the highway and struck truck #8718. The truck was turned around and pushed over onto Employee #1, who had meanwhile left the truck to get away from the out-of-control tractor when coworkers yelled. Employee #1 was killed. The state highway workers were in compliance with safety regulations.
