A woman was trapped in her Jeep after a semitrailer caused her to crash into a tractor Monday morning near Hebron, authorities said.
The semitrailer was traveling north on Greenwood Road to the south of Tryon Grove Road when it rear-ended a Jeep Cherokee that was following a slow-moving farm tractor towing a water tank, McHenry County Sheriff’s Office spokeswoman Sandra Rogers said.
The impact caused the Jeep to strike the tractor, and the semitrailer crashed into a ditch.
It took emergency crews 10 minutes to free a woman from the Jeep.
A Flight for Life medical helicopter took the woman to Advocate Condell Medical Center in Libertyville with serious injuries, Hebron-Alden-Greenwood Fire Protection District Chief Thomas Linneman said.
The drivers of the semitrailer and tractor were evaluated at the scene and released.
Fire and emergency crews from Hebron-Alden-Greenwood, Richmond, Woodstock, Wonder Lake and Mercyhealth responded to the incident.
The driver of the semitrailer was cited for failure to reduce speed to avoid a crash.
In a Facebook post Tuesday, the sheriff’s office reminded drivers of the importance of sharing the road with farm equipment.
“[Slow down] and give farm equipment room to work and move,” the post said.
