JOLIET, Ill. (AP) — An Illinois state trooper was seriously injured when his squad car was rear-ended along a suburban Chicago expressway where he had stopped to investigate an earlier crash.
The trooper had pulled behind two vehicles which had been involved in a crash along northbound Interstate 55 in Joliet when a Cadillac slammed into the back of his squad car Monday even though its emergency lights were activated, Illinois State Police said.
The trooper was airlifted to a hospital with serious injuries following the noontime Monday crash on the highway, which is also known as the Stevenson Expressway.
The 20-year-old man who was driving the Cadillac was hospitalized with minor injuries, police said.
Traffic was diverted off the expressway at US Route 30 until northbound lanes reopened about four hours after the crash.
