Detectives reported an unknown fluid leaking from one of the trucks onto the roadway, prompting a hazmat crew to respond and contain it. Southbound lanes were shut down during the cleanup and have since reopened.

Frequently Asked Questions
Why do semi trucks take so much longer to stop than cars?
A loaded semi can weigh 20 to 30 times more than a passenger car, and that extra weight means its brakes need much more distance to bring it to a stop, especially at highway speed.
What makes a crash between large trucks more dangerous than a typical car accident?
The size and weight difference means more energy is released on impact, which raises the chance of a vehicle rolling over or cargo and fluids spilling onto the road, as happened in this crash.
What is a truck's blind spot, and why does it matter in a crash like this?
Semi trucks have large blind spots along both sides, behind the trailer, and directly in front of the cab, so drivers nearby should avoid lingering in those zones, particularly when trucks are merging or changing lanes.
What to Do After a Truck Crash in Hazel Crest, IL
If you're involved in a crash with a semi-truck, move to a safe spot away from traffic if you're able to and call 911 right away. Even if you feel fine, get checked out by a medical professional, since injuries from a truck collision aren't always obvious right after impact. Take photos of the vehicles and the scene if it's safe to do so, and get the names and badge numbers of responding officers. Keep a copy of any police report once it's filed, and hold onto medical records tied to the crash in case you need them later.
