Truck accidents are not car accidents with bigger vehicles. Federal regulations control how the driver and company operate, and several parties can end up sharing the blame. Below, our legal team answers the questions we hear most often from Chicago truck accident victims and their families.
General Truck Accident Questions
How are truck accident cases different from car accident cases?
Truck accident cases carry more moving parts than a typical car crash claim. Here is what changes:
- Federal regulations: rules from the Federal Motor Carrier Safety Administration (FMCSA) that govern how trucking companies and drivers operate
- Multiple defendants: the driver, the trucking company, whoever loaded the cargo, and sometimes the manufacturer of a defective part
- More severe injuries: an 80,000-pound truck does damage a passenger car simply cannot
- Corporate legal teams: large carriers often have lawyers and adjusters working the case within hours of the crash
- Extensive documentation: driver logs, inspection records, and black box data that can make or break a claim
What federal regulations apply to truck drivers?
The Federal Motor Carrier Safety Administration regulates nearly everything about how a commercial truck operates on Illinois roads. The FMCSA regulations (49 CFR Parts 350-399) cover:
- Hours of Service: caps on how long a driver can be behind the wheel before resting
- Drug and alcohol testing: required screening before, during, and after employment
- Vehicle maintenance: inspection and repair standards the carrier has to meet
- Driver qualifications: CDL (commercial driver’s license) requirements and medical certification
- Cargo securement: rules for loading and strapping down freight so it doesn’t shift or fall
A violation of any of these rules can become powerful evidence of negligence in your case. Learn more about how FMCSA violations prove negligence.
What exactly are the hours-of-service rules truck drivers have to follow?
Under 49 CFR Part 395, a driver gets 11 hours of driving time after 10 consecutive hours off duty, inside a 14-hour on-duty window. Push past either limit and it works against the driver, not for them. Drivers also need a 30-minute break after 8 cumulative hours of driving, and the weekly cap runs 60 hours over 7 days or 70 hours over 8 days depending on the carrier’s schedule.
We see hours-of-service violations in a large share of the fatigue-related crashes we investigate. Read more in Truck Driver Fatigue: How Hours of Service Violations Cause Fatal Crashes and Electronic Logging Device (ELD) Data: Proving Trucker Hours Violations.
How long do I have to file a truck accident lawsuit?
Under 735 ILCS 5/13-202, you have 2 years from the accident date to file a personal injury lawsuit. For a deeper look at deadlines, see our overview of the Illinois statute of limitations for personal injury, or our truck-specific breakdown at How Long You Have to File a Truck Accident Lawsuit in Illinois.
Wrongful death claims run on a different clock. Under 740 ILCS 180/2, the family has 2 years from the date of death, which isn’t always the same date as the crash, to file a wrongful death claim.
If a government entity was involved, for example a USPS mail truck or a municipal garbage truck under contract with the city, the deadline can shrink to just 1 year under 745 ILCS 10/8-101. State agencies like the Illinois Department of Transportation are the exception: those claims go through the Illinois Court of Claims rather than a standard lawsuit, with their own separate rules and deadlines. Because the clock varies so much by defendant, don’t wait to have your case reviewed. You should also act quickly because trucking companies may legally destroy certain records after set periods, and evidence disappears rapidly.
Liability Questions
Who can be held responsible for a truck accident?
More than one party can end up on the hook. In our experience investigating these crashes, liability often falls on:
- Truck driver: for negligent driving, fatigue, distraction
- Trucking company: for negligent hiring, inadequate training, or pressure to violate HOS rules
- Cargo company: for improper loading causing imbalance or cargo spills
- Truck/parts manufacturer: for defective brakes, tires, or other components
- Maintenance provider: for negligent repairs
- Broker: for hiring an unqualified or unsafe carrier
Sorting out who actually pays takes investigation, not guesswork. Our full breakdown is at Who Is Liable in a Truck Accident? Understanding Responsibility Under Illinois Law.
Is the trucking company always liable for driver negligence?
Generally, yes. Under the doctrine of vicarious liability, employers are responsible for employee actions within the scope of employment. Trucking companies may try to claim the driver was an independent contractor, and owner-operators make this fight especially common.
Federal law pushes back on that defense. Under 49 CFR 376.12(c)(1), a lease agreement giving the carrier “exclusive possession, control, and use” of the truck can make the carrier legally responsible even when the driver technically owns the rig. How strong that presumption is depends on the jurisdiction and the facts of your case, so it isn’t an automatic win, but it’s a powerful argument in the right case. We cover this in detail in Owner-Operators and the Independent Contractor Defense in Truck Cases.
Can I still recover damages if I was partly at fault for the crash?
Yes, as long as your share of fault isn’t too high. Illinois follows modified comparative fault under 735 ILCS 5/2-1116. If you’re 50% or less at fault, your recovery is reduced by your percentage of fault. If a jury finds you more than 50% at fault, you recover nothing.
Trucking company adjusters push hard to shift blame onto the injured driver for exactly this reason, so don’t accept a fault percentage from an adjuster without a second opinion. We explain the math in Partly at Fault in a Truck Crash? The Illinois 51 Percent Rule.
Can I sue the freight broker that arranged the shipment?
Often, yes. For years, brokers argued that federal transportation law, the FAAAA, shielded them from negligent-hiring claims, and courts were split on the question. That question is settled now. In Montgomery v. Caribe Transport II, LLC, the U.S. Supreme Court held in May 2026 that broker negligent-hiring claims are not preempted by the FAAAA.
If a broker matched a shipper with a carrier it knew, or should have known, had a poor safety record, that broker can be a defendant in your case. Read more in Can You Sue the Freight Broker After a Truck Crash?
Specific Accident Type Questions
What causes jackknife accidents?
A jackknife happens when the trailer swings out and folds toward the cab, often at highway speed. Common causes include:
- Sudden or panic braking
- Slippery road conditions
- Improper braking technique
- Equipment malfunction
- Excessive speed for conditions
Read our detailed guide on jackknife truck accidents, causes, and liability.
What are underride accidents and why are they so deadly?
Underride accidents occur when a smaller vehicle slides under a truck’s trailer. These crashes are often fatal because the car’s safety features never get the chance to work, with the trailer striking the passenger compartment directly. Learn about underride accidents and safety regulations.
Are tanker truck accidents different from other truck accidents?
Yes. Tanker trucks carrying fuel, chemicals, or hazardous materials present unique dangers including explosions, chemical burns, and toxic exposure. They’re governed by additional hazmat regulations on top of standard FMCSA rules. Read our guide on tanker truck and hazmat accident claims.
Are accidents involving Amazon or FedEx delivery trucks handled differently?
Somewhat. Amazon relies heavily on contracted delivery companies rather than direct employees, which can complicate who is actually liable. FedEx uses a mix of company drivers and contracted ground carriers. In both setups, the corporate parent isn’t automatically off the hook just because the driver technically worked for a smaller contracted company.
We walk through how liability actually works in Amazon, FedEx & Delivery Truck Accidents: Who’s Liable?
Evidence and Investigation Questions
What evidence is important in truck accident cases?
The right evidence can make or break a truck accident claim. What we look for:
- Electronic Logging Device (ELD) data: shows driver hours and potential HOS violations
- Event Data Recorder (EDR): “black box” recording speed, braking, and other data before the crash
- Driver qualification files: CDL, medical certification, training records
- Inspection and maintenance records: vehicle condition history
- Drug and alcohol test results: post-accident testing is federally required
- Dispatch records: communications showing pressure to deliver
- GPS data: route and speed information
We go deeper on the black box specifically in Truck Black Box Evidence: How ELD and EDR Data Proves Fault in Chicago Truck Accidents.
How quickly do I need to act to preserve evidence?
Immediately. Trucking companies can legally destroy certain records after 6 months. An attorney can send a spoliation letter demanding evidence preservation. EDR data may be overwritten on the truck’s next trips if not downloaded promptly. We cover the specific steps and deadlines in Preserving Critical Evidence After a Truck Accident: Time-Sensitive Steps.
What happens if the trucking company destroys evidence anyway?
In Illinois, destroying or losing evidence you had a duty to preserve is called spoliation, and it’s treated as a form of negligence rather than its own separate claim. That rule comes from Boyd v. Travelers Insurance Co., 166 Ill. 2d 188 (1995).
Practically, that means if a carrier destroys ELD data or maintenance records after receiving a preservation letter, we can pursue a negligence claim over the destruction itself, and a court can allow the jury to assume the missing evidence would have hurt the carrier’s case. It’s one more reason to get a spoliation letter out fast, before that window closes.
Compensation Questions
What damages can I recover in a truck accident case?
- Medical expenses: all past and future treatment
- Lost wages: income lost during recovery
- Loss of earning capacity: if permanently disabled
- Pain and suffering: physical and emotional distress
- Disfigurement: scarring or permanent physical changes
- Loss of consortium: impact on spousal relationship
- Wrongful death damages: in fatal accidents
One detail worth knowing: under 735 ILCS 5/2-1117, your medical expenses stay fully recoverable from any liable defendant, regardless of how fault gets divided among multiple defendants. A separate 25%-fault threshold determines whether a given defendant owes a share of your other damages beyond medical bills. We explain how the fault math plays out generally in Partly at Fault in a Truck Crash? The Illinois 51 Percent Rule.
How is my compensation actually calculated?
There’s no fixed formula an attorney plugs numbers into. Insurers, and eventually juries, weigh your medical bills, lost income, the permanence of your injury, and the strength of the liability evidence together. A catastrophic injury with airtight liability evidence settles very differently than a moderate injury with disputed fault.
We walk through the specific factors in How Is Compensation Determined After a Semi-Truck Wreck in Chicago.
Are truck accident settlements larger than car accident settlements?
Yes, typically. This is because:
- Injuries are generally more severe
- Trucking companies carry higher insurance limits ($750,000 minimum federal requirement)
- Multiple defendants may share liability
- Corporate defendants want to avoid bad publicity
We compare the two head to head in Truck Accident Settlements vs. Car Accident Settlements: Key Differences.
Can I recover punitive damages against a trucking company?
In limited circumstances, yes. Illinois allows punitive damages when a defendant’s conduct goes beyond ordinary negligence and rises to willful or wanton behavior, for example a carrier that knowingly kept a driver on the road after repeated hours-of-service violations or ignored repeated maintenance warnings. These damages are meant to punish and deter, not just compensate, and courts don’t award them lightly.
We cover when they apply in Punitive Damages Against Trucking Companies in Illinois.
Insurance Questions
How much insurance do trucking companies carry?
Federal law requires minimum coverage of:
- $750,000: the floor for most commercial trucks hauling general freight
- $1,000,000 to $5,000,000: for carriers hauling hazardous materials, with the exact minimum depending on the hazmat category
Many carriers carry higher limits than the federal floor. Large trucking companies may be self-insured instead of buying a policy. We break down the specific tiers in How Much Insurance Do Trucking Companies Have to Carry?
Should I talk to the trucking company’s insurance adjuster?
No, not without an attorney. Trucking company insurers and lawyers begin investigating immediately after accidents, often arriving at the scene. Anything you say can be used against you. Let your attorney handle all communications. If you’ve already received a number from the adjuster, don’t sign anything before reading Should You Accept the Trucking Insurer’s First Settlement Offer?
Working With a Truck Accident Attorney
How much does it cost to hire a truck accident lawyer?
Nothing upfront. Truck accident cases like ours run on contingency fees, meaning you pay no attorney fees unless we win your case, and the fee comes out of the settlement or verdict rather than your pocket.
Given how quickly trucking companies deploy their own legal teams, waiting to “afford” a lawyer usually costs victims more than the fee itself. See exactly how the fee structure works in What a Chicago Truck Accident Lawyer Costs and How Contingency Fees Work.
