Who is liable in a truck accident? In Illinois, liability can reach far more parties than most people expect, including the driver, the motor carrier, the freight broker that hired it, the shipper that loaded the trailer, and the manufacturers of failed components, often several at once. Where the case is filed matters too, because under Illinois venue law, a crash on I-80 near Joliet may be litigated in Will County while a Dan Ryan wreck typically lands in the Circuit Court of Cook County’s Law Division, and identifying every defendant is what connects a catastrophic injury to enough insurance to cover it.
Understanding these layers matters because it usually determines whether an injured person recovers fair compensation or settles for whatever a single insurance policy will pay.
A typical car crash involves two drivers and two insurance companies, while behind one tractor-trailer you may find all of the following.
Figuring out who is liable in a truck accident means investigating each of these players. Each one owes duties to the public, and each one can breach those duties in ways that cause a catastrophic crash.
Most truck crash cases begin with the driver. Speeding, following too closely, distracted driving, driving while fatigued, and driving under the influence are all forms of negligence that can support a claim. Commercial drivers are held to high standards because they operate vehicles that can weigh 80,000 pounds when loaded, and small mistakes at that scale become catastrophic.
The driver is almost never the only defendant, though, and often not the most important one. Many drivers carry limited personal assets, and their conduct usually traces back to pressures and failures higher up the chain.
The motor carrier is usually the central defendant in a truck crash case, and there are several independent paths to holding it accountable.
Respondeat superior. Under this long-standing legal doctrine, an employer is responsible for the negligence of its employees committed within the scope of their work. If a driver was hauling a load for the carrier when he caused the crash, the carrier generally answers for his negligence.
Negligent hiring, training, and supervision. Carriers have their own duties separate from the driver’s conduct. A company that hires a driver with a history of violations, skimps on training, ignores hours-of-service problems, or pushes unrealistic delivery schedules can be liable for its own corporate negligence.
Federal operating authority. Interstate carriers operate under authority granted by the Federal Motor Carrier Safety Administration (FMCSA) and must comply with the Federal Motor Carrier Safety Regulations. A carrier’s FMCSA safety rating, inspection history, and violation record are public, and they often become powerful evidence of what the company knew about its own problems. Carriers sometimes try to hide behind “independent contractor” labels, but federal regulations and Illinois law frequently cut through that defense when the carrier controlled the work.
For decades, freight brokers argued that a federal statute, the Federal Aviation Administration Authorization Act (FAAAA), shielded them from personal injury lawsuits entirely. That changed in May 2026, when the United States Supreme Court decided Montgomery v. Caribe Transport II, LLC, a case that arose from a crash on an Illinois highway.
In a unanimous opinion by Justice Barrett, the Court held that a negligent hiring claim against a freight broker is not preempted by the FAAAA. As the Court’s syllabus puts it, “A claim that one company negligently hired another to transport goods is not preempted by the FAAAA because States retain authority to regulate safety ‘with respect to motor vehicles.’” Justice Kavanaugh’s concurring opinion noted that in 2022, about 500,000 reported truck accidents in the United States resulted in roughly 5,000 deaths and 114,000 injuries.
We wrote about this ruling in detail in our post on how the Supreme Court changed the game for truck crash victims. In short, brokers have access to federal safety data on every carrier they hire, and when a broker selects a carrier with documented safety deficiencies and that carrier hurts someone, the broker’s own carrier-selection decisions are now fair game in court. That includes traditional brokerage giants as well as app-based platforms, and if your crash involved a digitally brokered load, our Uber Freight accident lawyer page explains how those cases work.
The company that loaded the trailer can share responsibility too. Cargo that is overweight, unbalanced, or improperly secured changes how a truck handles, lengthens stopping distances, and can shift or spill in transit. When a load was sealed by the shipper and the driver had no realistic way to inspect it, liability for a cargo-related crash may rest primarily with the business that packed it. These claims require early investigation, because loading records, weight tickets, and dock camera footage do not stay available for long.
Sometimes the crash starts with the machine itself. Brake failures, tire blowouts, steering defects, coupling failures, and underride guard problems can all point to a defective product. In that situation, the manufacturer or distributor of the component can be held strictly liable, meaning an injured person does not have to prove the company was careless, only that the product was unreasonably dangerous and caused the harm. Product claims often proceed alongside negligence claims against the driver and carrier, and they require preserving the wrecked truck before it is repaired, salvaged, or scrapped.
All of this matters for a practical reason, because federal law sets minimum insurance levels for interstate motor carriers, and they are lower than most people expect. Under 49 CFR 387.9, the minimum financial responsibility for a for-hire carrier of non-hazardous freight is $750,000. Certain hazardous materials loads require $1,000,000 or $5,000,000 in coverage.
A catastrophic injury, such as a spinal cord injury, a traumatic brain injury, or an amputation, can produce lifetime losses that far exceed those figures. When people ask who is liable in a truck accident, what they often really need to know is where the coverage is. Brokers, shippers, and manufacturers typically carry their own substantial policies, and excess or umbrella coverage may sit above the carrier’s primary policy. Identifying every responsible party is how a case gets matched to the full scope of the harm rather than capped at one policy limit.
Deciding who is liable in a truck accident takes an investigation rather than a guess. It means sending preservation letters fast, pulling FMCSA data on the carrier, obtaining the broker-carrier agreement, examining loading records, and inspecting the vehicle for defects. It also means acting quickly, because trucking companies and their insurers begin building their defense within hours of a crash. Our Illinois truck accident lawyer page explains how we approach these cases from day one.
In one case from our firm’s practice, a truck driver died when the grab handle on his cab broke away, causing him to fall backward. We pursued the component failure and recovered a $930,000 settlement for his surviving family at mediation.
Liability can reach the driver, the trucking company (through respondeat superior and its own negligent hiring or supervision), the freight broker that selected the carrier, the shipper that loaded the cargo, and the manufacturers of defective components, and serious cases often involve several defendants.
Yes, because in Montgomery v. Caribe Transport II, LLC (May 2026), the U.S. Supreme Court unanimously held that a negligent hiring claim against a freight broker is not preempted by the FAAAA, opening the door to claims based on the broker's carrier-selection decisions.
It matters because recovery is limited by collectible insurance. Federal minimums for carriers are lower than most catastrophic losses, and brokers, shippers, and manufacturers carry their own policies that can matter enormously in serious injury cases.
