A semi-truck driver was cited for running a stop sign and causing a crash that left a pickup truck driver seriously injured near Marengo on Monday.

The McHenry County Sheriff’s Office and Marengo Fire Rescue Protection District responded around 3:15 p.m. Monday to County Line Road and Kishwaukee Valley Road.

McHenry County Sheriff’s Deputy Kevin Byrnes said an investigation showed a 2000 Mack tractor-trailer was traveling northbound on County Line Road.

For unknown reasons, the Mack driver disregarded the posted stop sign and crashed into a 2001 Ford Explorer Sport Tract, which was traveling westbound on Kishwaukee Valley Road.

The tractor-trailer then left the road and crashed into a utility pole on the west side of County Line Road.

Byrnes said the driver of the Ford was transported to OSF Saint Anthony Medical Center in Rockford with serious but non-life-threatening injuries.

The driver of the Mack was transported to Mercyhealth Hospital in Harvard with minor injuries. He was also cited for disregarding a stop sign.

Alex Vucha, a spokesperson for the Marengo Fire Rescue Protection District, said a hazardous condition was created after the tractor-trailer struck the utility pole, causing the power lines to lean over the roadway.

ComEd responded to the scene to mitigate the hazard of the electrical pole.

The Boone County Fire Protection District #2 and Boone County Sheriff’s Office also assisted at the scene.

The roadway was closed by the McHenry County Sheriff’s Office for several hours and reopened by around 7:30 p.m. Monday, Vucha said.
