A school bus rolled over on Interstate 294 in a southwest Chicago suburb during rush hour Tuesday, sending three people to the hospital after authorities believe the driver suffered a seizure while driving.
Multiple lanes were shut down after the accident.
Twelve Chicago high school girls were on the bus at the time of the crash, along with an adult driver and a coach, police said. Resurrection College Prep High School's bowling team had rented the bus, a school official told NBC 5. None of the injuries suffered by the passengers were serious. The condition of the driver was not immediately clear.
The driver and two female passengers were taken to local area hospitals for evaluation, authorities said.
"Traffic was heavy," Caryl King, a coach who was on the bus, said. "The bus started to veer to the right and all of a sudden we were seeing grass."
King said the bus was taking the team to a high school tournament on Chicago's South Side.
Illinois State Police said the bus rolled over around 5:15 p.m. in the southbound lanes near Archer Avenue, closing down two lanes of the roadway.
Police said a preliminary investigation indicates the driver suffered a seizure while driving.
