BOISE, Idaho (AP) Idaho State Police say an accident involving a fuel tanker truck has caused a 1,200-gallon (4,542 liters) fuel spill into a ditch connected to a river near Powell Junction.
KBOI-TV reports the accident occurred Friday morning on Highway 12.
Police say the tanker driver had been heading west when he went off the roadway for an unknown reason.
Police say the trailer became disconnected from the tanker and overturned. The driver was trapped inside and was rescued by responders.
