CHICAGO (CBS) – Three people were hurt Monday morning in a crash on the outbound Kennedy Expressway, involving a truck and a charter bus.
Three ambulances were called to the outbound Kennedy near Diversey Avenue around 12:30 p.m., police said.
A witness told police someone in a car abruptly cut off the charter bus, forcing the driver to take evasive action to avoid a crash. The bus, instead, hit a semi-trailer truck.
Three people were taken to Saint Mary Medical Center, Fire Media Affairs spokesman Richard Rosado said. One was in serious condition, while the two others were listed in good condition.
Illinois State Police are investigating.
