At 8:47 a.m., the vehicle was speeding south on I-55 near Route 6 when the driver lost control and the vehicle went into a ditch, struck a guardrail and pole and turned over, according to Illinois State Police.
All four people inside the vehicle were hospitalized, including the three passengers, a 42-year-old Cicero woman and two children, ages 3 and 5.
The 5-year-old boy, identified as Malcolm Townsel of Belleville, suffered multiple injuries in the crash and was taken to Saint Joseph Medical Center in Joliet, where he was pronounced dead at 9:40 a.m., according to the Will County coroner's office.
The conditions of the woman and the other child were not immediately available Tuesday afternoon.
The driver, a 42-year-old Belleville man, was cited for driving too fast for conditions and child restraint, police said.
Illinois State Police are investigating the crash.
