Oregon State Police said 36-year-old Justin Shaffer was driving along a curve on Highway 138 before the truck rolled down an embankment and into the water. Police were investigating the cause of the crash.

Shaffer was seriously hurt and taken to a hospital in Bend, troopers said.

Pictures showed the truck halfway submerged in the rushing waters.

The Terrain Tamers Chip Hauling, Inc. trailer was empty, but an estimated 150 gallons of diesel fuel from the cab spilled into the river.
