Interstate 90

The Wyoming Highway Patrol says driver fatigue may be to blame for a single-vehicle rollover crash that left two Washington residents dead.

A man is dead after he was hit by a motorhome while retrieving a tire on Interstate 90, the Wyoming Highway Patrol says.

One person was killed and two others were injured in a single-vehicle crash in Campbell County early Friday morning, the Wyoming Highway Patrol says.

The 8 second video showed complete whiteout conditions on the highway, with very little visibility.

Authorities say at least five people have died after a pileup Friday evening on Interstate 90 in Montana.

The Wyoming Highway Patrol on Tuesday shared multiple pictures of blow-over crashes on the state's roadways.
