Washington State Patrol says Mark Sasser, 56, of Burbank, was driving west on I-82 around 7 a.m. when his Chevrolet Silverado left the roadway. The truck then traveled back across both westbound lanes and rolled over onto its top.
Sasser was ejected from the vehicle. He was taken to Toppenish Community Hospital, but he died shortly afterward.
The cause of the crash is still under investigation. WSP has not announced whether alcohol or drugs played a role in the accident.
