OTTAWA, La Salle County, Ill., Sept. 29, 2026 — One person was hospitalized after a five-vehicle crash on Monday afternoon, September 28, on westbound Interstate 80 near Utica. The wreck happened around 1 p.m. under the East Ninth Road overpass and involved three semitrailer trucks, a passenger van, and a tandem truck.
Utica Fire and EMS, Illinois State Police, Interstate Towing, and La Salle Fire crews responded to the scene, according to the report. One person was taken to OSF HealthCare Saint Elizabeth Medical Center in Peru for treatment. The condition of that patient has not been released.
It's not yet clear how the chain-reaction crash started or whether the westbound lanes were closed for an extended period during cleanup. Illinois State Police have not released additional details on possible citations or contributing factors, and the crash remains under investigation.
Our thoughts are with those who were injured, and we wish them a full recovery.
What Actually Reduces Multi-Vehicle Pileups on Highways Like I-80
Speed is the reason a fender bender on a city street becomes a five-vehicle pileup on a highway. At interstate speeds, the distance a driver needs to stop safely stretches out quickly, and a few seconds of following too close or looking away leave no room to react when traffic ahead slows or a vehicle in front loses control. Add a mix of heavy trucks and passenger vehicles moving at different speeds, and one lockup or swerve can pull in several more vehicles before anyone has time to brake.
Road design plays a real role in reducing these crashes. Wider shoulders give drivers somewhere to go when traffic bunches up, rumble strips warn distracted drivers before they drift, and better lighting and signage near overpasses and merge points give everyone more warning time. Variable speed limits, now used on some interstates during heavy traffic or bad weather, gradually slow vehicles rather than forcing sudden stops.
Driver behavior still matters as much as the road itself. According to the National Highway Traffic Safety Administration, 28,595 large-truck occupants were injured in multi-vehicle crashes involving large trucks in 2023. Keeping a longer gap behind the vehicle ahead, especially near trucks with long stopping distances, remains one of the few things individual drivers control once they're on a highway moving at speed.
Frequently Asked Questions
Why does following distance matter so much on highways?
At highway speeds, stopping distance grows fast. A gap that feels safe at 30 mph can close in a fraction of the time at 65 mph or 70 mph, leaving little time to react if traffic ahead brakes suddenly.
Do secondary crashes often happen after the first one?
Yes. Once a crash blocks or slows lanes, drivers approaching the scene, especially in poor visibility or heavy traffic, can strike stopped vehicles or emergency responders before the scene is fully cleared.
Why are multi-vehicle crashes harder to investigate than single-car wrecks?
Investigators have to sort out the order in which vehicles struck each other, how many drivers were involved, and how speed and following distance factored in for each one, which takes longer than reconstructing a single-vehicle crash.
What usually causes a highway pileup?
Common factors include following too closely, sudden braking, reduced visibility from weather or glare, and a mix of vehicle sizes and speeds that makes it harder for everyone to react in time.
What to Do After a Multi-Vehicle Crash in Ottawa, IL
If you're involved in or witness a multi-vehicle crash on a highway near Ottawa, move to a safe location away from traffic if possible and call 911 right away. Even if you feel fine, some injuries from a highway-speed collision don't show symptoms immediately, so a medical evaluation soon after the crash is worth doing.
Get the names and contact information of anyone else involved, and if law enforcement responds, ask how to obtain a copy of the official crash report once it's filed. That report will matter for insurance claims and for understanding what happened once the investigation wraps up.
