The Iowa State Patrol reports that about 6:25 AM, 63-year-old Conrad Bensen of Hawarden was northbound on Highway 75, three miles north of Sioux Center, or a mile north of the Carmel road in a 1999 Ford pickup. Sixty-six-year-old James Heuertz of George was also northbound on 75 in a 2004 Freightliner semi.
Benson was slowing to turn west into a farm driveway. Heuertz was unable to stop in time and struck the rear of the pickup, pushing it into the west ditch.
Bensen was transported to the Sioux Center Hospital and later to a Sioux Falls hospital by Sioux Center Ambulance.
The preliminary accident report does not list the amount of damage to the vehicles involved, or address whether any charges were filed.
The State Patrol says the investigation is ongoing.
