A semi tractor-trailer slid on icy roads and crashed into a guardrail in south-central Montana, causing the cab to go into the river and the load of toilet paper to be strewn across the highway. Red Lodge Fire and Rescue says the driver suffered minor injuries Monday morning. Up to 100 gallons of diesel fuel spilled into the Clarks Fork of the Yellowstone River near Belfry. Officials say the driver lost control of the rig while approaching an S-curve on Montana Highway 72. The semi hit the end of a bridge guardrail, splitting the cab from the trailer. The river was only a couple feet deep and the semi stayed on its wheels.
