A bystander called for help after finding a man seriously injured over four hours after the man drove into a field and his car rolled over near Harvard, authorities said.

The Harvard Fire Protection District, Harvard Police Department and McHenry County Sheriff’s Office responded around 4:09 a.m. Friday to the area of Oak Grove Road and Ramer Road in unincorporated Harvard for a vehicle crash with injuries.

Harvard Fire Chief John Kimmel said crews arrived to find a single-vehicle crash off of the roadway.

The passenger car drove off of Ramer Road around 11:30 p.m. Thursday and rolled over into a field, resulting in heavy damage.

The driver, who was the sole occupant of the car, was not able to call for help, Kimmel said.

The adult male, who was in his 20s or 30s, eventually crawled from the crash scene and was able to flag someone down.

Kimmel said the bystander called 911 and paramedics arrived to find that the victim was seriously injured.

A medical helicopter was requested to the scene but they were unable to fly due to weather conditions.

The man was transported to Javon Bea Hospital–Riverside in Rockford, which is a Level 1 trauma center, for treatment.

His injuries were not life-threatening, Kimmel said.

The sheriff’s office shut down Ramer Road between Lawrence Road and Oak Grove Road for several hours for the crash investigation.

The cause of the crash remains under investigation by the McHenry County Sheriff’s Office.
