Following the crash, all inbound lanes of I-90 were closed for the accident investigation. All lanes have since reopened.
Illinois State Police issued a citation to the truck driver for failure to reduce speed and avoid collision.
Alcohol and drugs are not being considered a contributing factor, police said.
