Why Truck Accident Cases Are More Complicated Than Car Accidents
Key Takeaways
- Commercial drivers and the companies that employ them follow federal safety regulations that never apply to ordinary passenger vehicle drivers.
- Responsibility for a single-truck crash can reach the motor carrier, the cargo loader, a maintenance shop, and other businesses.
- Federal rules allow carriers to discard driver duty logs after six months, long before the deadline to file arrives.
- Modified comparative fault bars recovery once an injured person's share of responsibility passes half.
Truck accident cases are complicated because federal regulations, several companies, and short evidence deadlines all apply at once. After a collision with a commercial truck, you are not dealing with one driver and one insurance policy. You are dealing with a transportation business that often has investigators reviewing the wreck within hours of the call coming in.
That head start matters, because most of the proof that decides a truck case sits inside the carrier's own systems rather than at the roadside. At Conboy Law, we approach these claims by working backward from the records that disappear soonest. If a commercial truck hit you or someone in your family, our team can review what happened and explain the options open to you.
A Truck Crash Is Governed by Rules That Never Apply to a Car Crash
Two drivers in a car crash answer to the same rules of the road. A commercial driver answers to those rules and to a federal safety code governing how long they drive, how the vehicle is maintained, and how the company that dispatched them keeps records. When a rule in that code is broken, the violation becomes evidence about how the crash happened.
Federal Hours-of-Service Limits Commercial Drivers Must Follow
Fatigue rules are the part of that code that surfaces most often after a serious wreck. Federal law sets several fixed limits on a property-carrying driver's day:
- A driver may not begin driving without first taking 10 consecutive hours off duty.
- Driving must stop once 14 consecutive hours have passed since coming on duty.
- Within that window, total driving time may not exceed 11 hours.
- A break of at least 30 consecutive minutes is required after 8 hours of driving time.
- Weekly on-duty totals are capped at 60 hours in 7 days or 70 hours in 8 days, depending on the carrier's operating schedule.
These limits appear in the Code of Federal Regulations at 49 CFR 395.3, and a driver who pushed past them presents a different problem than one who simply looked away.
How Illinois Applies Federal Trucking Rules to In-State Carriers
People often assume these rules reach only interstate haulers. The Illinois Compiled Statutes adopt large portions of the federal motor carrier safety regulations directly into state law at 625 ILCS 5/18b-105, including the parts covering driver qualifications, vehicle inspection and repair, hours of service, and controlled substance testing.
Illinois adopts substantial portions of the Federal Motor Carrier Safety Regulations for carriers operating within the state, including rules addressing driver qualifications, hours of service, vehicle safety, and drug and alcohol testing. State-specific exceptions and modifications may apply to some intrastate operations.
Responsibility Can Extend Well Past the Person Driving
In most car crashes, fault gets sorted between two drivers and two insurance companies. Commercial trucking is rarely a one-person operation, so a single wreck can raise questions about several businesses at once. Working out who did what is often the slowest part of the case.
When the Motor Carrier Is Responsible for Its Driver
Under a legal doctrine called respondeat superior, an employer can be held responsible for the negligent acts of an employee carried out within the scope of employment. That doctrine is why a claim after a truck crash usually names the carrier and not only the person behind the wheel.
A carrier can also be responsible for its own conduct, separate from anything the driver did. Negligent hiring, negligent training, negligent supervision, and negligent retention are each independent theories. If a company keeps dispatching a driver after a documented pattern of falsified logs, that decision becomes its own question.
Companies Beyond the Driver's Employer
Freight moves through a chain of businesses, and any link in that chain can contribute to a crash. The following parties may share responsibility depending on what an investigation shows:
- The motor carrier that employed the driver and set the delivery schedule.
- The company that owned the tractor or the trailer, when ownership is split between them.
- The business that loaded or secured the cargo.
- The shop responsible for inspection, repair, and maintenance.
- The manufacturer of a component that failed, such as a brake assembly or a tire.
- The broker or shipper that arranged the load.
Each added party brings its own insurer and defense counsel, which explains much of why these claims take longer.
The Evidence Is Different, and Much of It Has an Expiration Date
A car crash is usually reconstructed from photographs, a police report, and what the people involved remember. A truck crash is reconstructed from data, and nearly all of it belongs to the trucking company, not to you.
Records a Carrier Is Only Required to Keep for a Limited Time
Federal rules set retention periods, and those periods run shorter than most people expect. A motor carrier must keep records of duty status and supporting documents for at least six months from the date of receipt under 49 CFR 395.8.
A separate rule at 49 CFR 390.15 requires carriers to maintain an accident register for three years after each crash, together with copies of accident reports required by state agencies or insurers. Six months is the number that causes the most harm. The state allows two years to file suit, so the logs showing what a driver did that week can lawfully be gone well before that deadline approaches.
Post-Crash Drug and Alcohol Testing Deadlines
Federal post-accident drug and alcohol testing is required only in certain qualifying crashes under 49 CFR § 382.303, including fatal crashes and some injury or tow-away crashes involving a moving-traffic citation. When testing is required, the employer must stop attempting an alcohol test after eight hours and a controlled-substance test after 32 hours.
Once those windows close without a test, that category of proof does not come back. No amount of later investigation recreates it.

Commercial Insurance Changes How the Claim Is Defended
Insurance is another place where the two kinds of claims stop resembling each other. Federal law requires for-hire carriers moving non-hazardous property in interstate commerce, in vehicles rated at 10,001 pounds or more, to carry at least $750,000 in public liability coverage under 49 CFR 387.9.
Many carriers hold considerably more than that minimum through layered or excess policies. Larger limits do not mean a larger recovery, and no honest assessment can promise one. What larger limits do mean is greater financial exposure for the insurer, and insurers defend greater exposure harder.
Those policies can also sit above one another in tiers, which affects the order in which they respond to a claim. Untangling that structure takes time and usually requires the carrier to produce documents it has little interest in producing.
Exposure of that size is also why carriers send investigators and defense counsel to the scene while the road is still closed. They are not waiting for a demand letter to begin building a position. Someone who waits several months to look into the crash starts from behind.
There is a practical consequence for anyone speaking with an adjuster directly. Recorded statements taken early are used later to support arguments about speed, lane position, and reaction time. Declining to give one until you have advice is a reasonable choice.
Illinois Deadlines and Fault Rules That Shape a Truck Accident Claim
How Long You Have to File a Truck Accident Claim
Most personal injury actions in this state must be commenced within two years after the cause of action accrued under 735 ILCS 5/13-202. When a crash causes a death, the Wrongful Death Act requires the action to be brought within two years after the date of death.
Two years can sound generous next to a six-month log retention period. In practice, the useful evidence in a trucking case has a far shorter life than the deadline to file.
How Shared Fault Is Used Differently in Truck Cases
Illinois follows a modified comparative fault. Under 735 ILCS 5/2-1116, an injured person is barred from recovering damages when their contributory fault is more than 50 percent of the proximate cause, and any recovery at 50 percent or less is reduced in proportion to that fault.
The rule itself is the same one applied after a car crash. What changes is the volume of resources aimed at it. Carriers commonly retain reconstruction engineers and download vehicle telematics within days, assembling a fault percentage while the injured person is still in a hospital bed.
Every point of assigned responsibility carries a financial consequence, which is why documentation gathered early matters so much.
Frequently Asked Questions About Truck Accident Claims in Chicago
Most injury actions must be filed within two years of the crash. A claim arising from a death generally must be brought within two years of the date of death.
More parties, more records, and more insurers are involved. Each company brings separate counsel, and document production from a carrier is rarely quick.
Sometimes. A contractor label does not settle the question, and a company may still face claims based on its own hiring, training, or supervision decisions.
Carriers must keep duty status records for at least six months. After that, the records may be discarded unless a preservation demand has already been made.
In large part, yes. State law adopts many of the federal motor carrier safety regulations, so intrastate carriers answer to those standards as well.
