Illinois State Police say the crash happened around 8:15 Monday morning on southbound Interstate 55 at LaGrange road in suburban Countryside, about 20 miles southwest of Chicago.
One of the vehicles traveling behind the governor's vehicle lost control on the slippery roadway and struck the rear tandem axle of a truck trailer.
It was driven by a member of the State Police unit that protects the governor. The driver was treated and released from a local hospital.
The governor's vehicle was not involved.
