A 35-year-old man was taken by medical helicopter to the hospital in serious condition after he crashed into the rear of a stopped truck on Route 47 near Huntley.

The McHenry County Sheriff’s Office and Huntley Fire Protection District responded around 1:45 p.m. Saturday to Route 47 and Conley Road in unincorporated Huntley.

McHenry County Sheriff’s Deputy Tim Creighton said two vehicles were involved — a 2017 Ford Fiesta and a 2018 Ford F-450 truck. Both were traveling southbound at the time of the crash.

An investigation showed that southbound traffic on Route 47 was slowing down to a stop for a vehicle that was turning left onto Conley Road, Creighton said.

The driver of the Ford Fiesta, a 35-year-old Woodstock man, failed to identify that traffic was stopped.

Creighton said the Ford Fiesta rear-ended the Ford F-450 truck, which was driven by a 39-year-old Elgin man.

The 35-year-old man driving the Ford Fiesta was seriously injured and paramedics transported him to Northwestern Medicine Hospital in Huntley.

A LifeNet medical helicopter landed at the hospital and transferred the man to Advocate Condell Medical Center in Libertyville for further treatment, Creighton said.

No one else was inside the Ford Fiesta at the time of the crash.

The 39-year-old man driving the Ford F-450 truck along with a 52-year-old Genoa man, who was in the truck’s passenger seat, were both treated for minor injuries.

The roadway was shut down in both directions and traffic had to be diverted for approximately two and a half hours Saturday afternoon.

The crash is still under investigation by the McHenry County Sheriff’s Office Major Crash Investigation Unit. Alcohol is not believed to be a factor in the crash.
