According to the Utah Department of Public Safety, a 2013 Isuzu box van was traveling west near mile marker 33 when a 1998 Nissan Pathfinder drifted from the right lane and struck the side of the box van.
The van pulled over to the side of the road, a statement from DPS said, and a 2014 Freightliner semi-trailer approached the area.
"[The semi-trailer] driver saw the Nissan traveling slow in the right lane and moved to the left lane to pass," the statement said. "As the [semi-trailer] was overtaking the Nissan, the Nissan moved into the left lane. The [semi-trailer] struck the rear of the Nissan."
The Pathfinder went off the right side of the road and rolled, then came to a stop on the passenger side.
The driver of the Pathfinder was not wearing a seat belt and was ejected from the vehicle, the statement said. DPS has not identified the driver, but they said he suffered fatal injuries.
