Gun violence unleashed on a Chicago-area expressway again Thursday night when a truck driver was shot driving down the Dan Ryan Expressway.

The 68-year-old Chicago man was traveling on the busy inbound lanes of the Day Ryan Expressway between 95th and 87th Streets around 11:45 p.m. when someone fired shots into the truck’s cab, shattering the window and striking the man in the mouth.

Illinois State Police said the driver was rushed to Oak Lawn’s Advocate Christ Medical Center in critical condition.

It’s unclear if the semi driver was the intended target or if the gunman was firing at someone else and hit the semi instead, police said.

No one else was injured in the shooting, according to police.

Thursday night’s shooting was the 20th expressway shooting of the year, despite state police adding extra patrols in February to try to stop the high-speed violence.
