A crash with a semi-truck is not a fender bender. The truck can outweigh your car by tens of thousands of pounds, and the aftermath pulls in a trucking company, a commercial insurer, and paperwork you have never dealt with before.
What you do in the first hours and days can decide whether you get full compensation or get outmaneuvered by people who handle these crashes for a living.
Illinois law gives you a clear path forward, and D&W Law Group offers free consultations to injured drivers, passengers, and pedestrians across the Chicago area.
Key Takeaways
- Illinois requires reporting any crash with injury, death, or significant property damage, and truck crashes almost always qualify.
- Motor carriers keep an accident register for only three years, and electronic crash data can vanish much sooner without a legal hold.
- Under modified comparative negligence, you can still recover if your share of fault stays at 50 percent or below.
- Most injury claims must be filed within two years, but claims against a government entity carry a one-year window.
- An attorney can start preserving evidence within days, while the carrier’s team is already building its defense.
Call 911 and Get Medical Care First
Nothing matters more than injuries. Call 911 so police and paramedics reach the scene, and get checked out even if you feel fine, because adrenaline hides pain and a same-day medical record ties your injuries to the crash.
You also have to report a qualifying crash. When police investigate, the responding agency files the report under 625 ILCS 5/11-408.
If no officer responds, you file a report yourself within 10 days. Either way, the police record is independent of the trucking company’s own investigators.
Document the Scene Before You Leave
If you can move safely, gather evidence before it disappears. Try to capture:
- Photos of both vehicles, the truck’s DOT number, plates, skid marks, and debris.
- Names and numbers for the driver, the trucking company, and any witnesses.
- The officer’s name and badge number, and the crash report number.
According to IDOT crash data, tractor-trailers were involved in 3.7 percent of Illinois crashes but 8.4 percent of fatal ones in 2024. That evidence often decides whether a claim settles fairly or turns into a fight.
Who Can Be Held Liable for a Truck Accident
A car crash usually has one defendant. A truck crash can have several: the driver, the motor carrier, the company that loaded the cargo, a maintenance contractor, or a parts manufacturer.
Sorting out who controlled the driver, the truck, or the freight takes real investigation. That is where an attorney earns their value, pulling driver qualification files, lease agreements, and dispatch records before the carrier’s legal team controls the story.

Why Truck Accident Evidence Disappears Fast
Trucks carry electronic control modules and logging devices that record speed, braking, and hours driven, and they record over a rolling buffer, so crash data can be overwritten within weeks.
Under 49 CFR 390.15, carriers keep an accident register for only three years, and that is a floor, not a guarantee the black box data lasts that long. A preservation letter sent fast enough locks the evidence down before it is gone.
How Fault Affects Your Compensation
Shared blame does not kill your claim in Illinois. Under modified comparative negligence (735 ILCS 5/2-1116), you can recover as long as you are less than 50 percent at fault, with your award reduced by your share. A driver found 20 percent at fault still collects 80 percent.
Insurers and juries weigh everything from lane position to following distance, so the evidence you preserve early shapes that percentage directly.
How Long You Have to File a Claim
Deadlines in truck cases are strict, and missing one can end a strong case:
- Most injury claims: two years from the crash under 735 ILCS 5/13-202.
- Government defendants, like a municipal vehicle: one year under the Tort Immunity Act. The CTA is separate, with its own one-year deadline plus a written notice within six months under the Metropolitan Transit Authority Act.
- Wrongful death claims: two years from the date of death, not the crash.
Mistakes That Can Hurt Your Claim
A few missteps show up again and again:
- Giving the trucking company’s insurer a recorded statement before you have your own counsel.
- Taking a fast settlement before you know the full extent of your injuries.
- Waiting weeks to hire an attorney, handing the carrier’s rapid-response team a head start.
Frequently Asked Questions
Who can be held liable for a truck accident in Illinois?
The driver, the motor carrier, a cargo loader, a maintenance contractor, or a parts manufacturer, depending on what caused the crash. A truck accident attorney can review dispatch and maintenance records to find every responsible party, not just the driver on the police report.
How long do I have to file a truck accident claim in Illinois?
Two years from the crash under 735 ILCS 5/13-202, or one year against a government entity, and a CTA claim also needs written notice within six months. Because evidence disappears well before either deadline, talk to a lawyer early.
What if I was partly at fault for the truck accident?
You can still recover if your fault is 50 percent or below, with your award reduced by your share, so 20 percent fault still pays 80 percent. An attorney can keep the carrier’s insurer from shifting blame onto you.
Do I need to call the police after a truck accident?
Yes. Illinois requires reporting any crash with injury, death, or significant property damage, and the police record is often the most reliable evidence in the claim.
How is a truck accident claim different from a car accident claim?
Truck crashes involve multiple liable parties, federal safety rules, and electronic data that can vanish within weeks without a preservation request. That added complexity is why people bring in an attorney sooner.
