Trucking Accident Liability in Kentucky
Multiple parties can be legally responsible after a semi-truck crash in Kentucky.
Knowing who they are changes how much you recover.
On This Page
Trucking accident liability in Kentucky can extend to the truck driver, the motor carrier, a freight broker, the shipper, a maintenance company, and the truck or parts manufacturer. Under 49 U.S.C. and FMCSA regulations, multiple federal rules establish the standard of care for each party. When more than one party shares fault, KRS 411.182 Kentucky’s pure comparative fault law determines how compensation is divided.
Why Trucking Accident Liability Is Different From a Car Crash
A collision with a semi-truck is not the same as a rear-end fender bender. According to the National Highway Traffic Safety Administration’s 2023 Large Truck Crash Facts, 5,472 people died in large-truck crashes that year, and roughly 153,000 more were injured. Seventy percent of those killed were in the other vehicle, not the truck. A fully loaded commercial truck can reach 80,000 pounds under federal weight limits. When something goes wrong at highway speed, the damage is catastrophic. And because trucking is a multi-party industry, the question of who is legally responsible is rarely simple.

Our truck accident practice area handles these cases from start to finish. This page covers the liability side: who can be held responsible, what FMCSA rules apply, and how Kentucky allocates fault.
Who Can Be Held Liable in a Kentucky Trucking Accident?
Building a strong trucking case starts by identifying every party whose negligence contributed to the crash. Truck accidents routinely involve more than one defendant. Here are the six most common:
-
The Truck Driver
Drivers are directly liable for their own negligence. Common violations include exceeding the FMCSA hours-of-service limits under 49 CFR Part 395 (11 hours of driving maximum within a 14-hour window), driving while impaired, distracted driving, and speeding. An FMCSA Large Truck Crash Causation Study found driver fatigue, prescription drug use, and moving too fast for conditions among the leading driver-related causes of crashes.
-
The Motor Carrier (Trucking Company)
The carrier that employs the driver is almost always a primary defendant. Under the doctrine of respondeat superior, a company is automatically responsible for its employee’s actions within the scope of employment. Beyond vicarious liability, carriers face direct claims under 49 CFR Part 391, which requires them to verify a driver’s commercial driver’s license, employment history, drug and alcohol testing results, and driving record before hiring. Skipping these checks is negligent hiring and creates direct liability separate from the driver’s own fault.
-
The Freight Broker
Freight brokers connect shippers with trucking companies. When a broker selects a carrier with a known history of safety violations, that selection decision can result in liability for injuries. This is an active legal area: the U.S. Supreme Court heard oral arguments in Montgomery v. Caribe Transport II, LLC in March 2026, a case examining whether state negligence claims against brokers survive federal preemption under the Federal Aviation Administration Authorization Act (FAAAA). The outcome could determine the scope of broker liability nationwide.
-
The Shipper
Shippers who load freight onto a truck carry a legal duty to load cargo safely and within federal weight limits. Under 49 CFR Part 393, Subpart I, cargo must be properly secured, distributed, and weight-compliant. An overloaded or improperly balanced load can cause a truck to roll, jackknife, or shed debris on a Kentucky highway. When cargo failure triggers the crash, the shipper shares liability.
-
The Maintenance Company
Third-party shops that service commercial trucks are responsible for doing the job correctly. The FMCSA’s maintenance regulations at 49 CFR Part 396 require carriers to systematically inspect, repair, and maintain all vehicles. When an outside shop performs faulty brake work, fails to flag a defective tire, or clears a truck that should have stayed off the road, that shop can be held directly responsible for resulting injuries.
-
The Truck or Parts Manufacturer
If a defective component caused the crash regardless of how it was maintained, the manufacturer bears product liability. Common defective parts in truck accident cases include brake systems, tires, steering components, and trailer couplings. Under product liability law, a manufacturer can be held strictly liable when a defective design or manufacturing error causes a crash, even without proving the company knew about the flaw.
FMCSA Regulations Set the Standard of Care
The Federal Motor Carrier Safety Regulations are published in Title 49 of the Code of Federal Regulations. Key regulations for liability analysis include:
49 CFR Part 391 (Driver qualifications: licensing, background checks, medical fitness)
49 CFR Part 395 (Hours of service: maximum driving time, rest requirements)
49 CFR Part 396 (Inspection, repair, and maintenance of vehicles)
49 CFR Part 393, Subpart I (Cargo securement standards)
When a party violates any of these regulations and that violation causes a crash, it is strong evidence of negligence per se. Courts use these federal rules as the baseline standard of care in trucking liability cases across Kentucky.
How Kentucky Distributes Fault Among Multiple Defendants
Kentucky is a pure comparative fault state. Under KRS 411.182, fault is divided among all responsible parties as a percentage. The injured person’s recovery is reduced by their own share of fault, but they can still recover even if they are found mostly at fault. This stands in contrast to modified comparative fault states, where a claimant above a threshold (often 50%) recovers nothing.
Here is how that works in practice for a trucking case. Suppose a jury finds the truck driver 40% at fault for speeding, the motor carrier 35% at fault for negligent hiring, the freight broker 15% at fault for selecting an unsafe carrier, and the injured driver 10% at fault for following too closely. Total damages are assessed at $500,000. The injured driver recovers $450,000, reflecting the 10% reduction for their own fault, distributed across the three defendant parties based on their percentages.
What this means for you: Because Kentucky allows recovery even when multiple parties share fault, your job is to make sure no responsible party goes unidentified. A case that looks like it is only against the truck driver can often be expanded to include the carrier, broker, shipper, or maintenance company. Each additional defendant is a separate source of recovery and insurance coverage.

The Evidence That Determines Liability
Trucking cases generate far more usable evidence than a typical car crash, but much of it disappears fast. The FMCSA’s electronic logging device (ELD) mandate requires carriers to record hours of service electronically. The truck’s event data recorder captures speed, braking, and steering data in the seconds before impact. Driver qualification files, drug test results, dispatch logs, and maintenance records speak directly to the liability of each party. Understanding how to preserve trucking evidence immediately after a crash matters: ELD data can be overwritten within 30 days.
Sam Aguiar Injury Lawyers has exclusive access to statewide DOT and TriMarc camera footage, with archives going back six months. Our dedicated trucking team moves quickly to secure the records that carriers and insurers would rather see disappear.
What Trucking Companies Do Right After a Crash
Large motor carriers deploy in-house response teams the moment a serious crash is reported. Their risk management staff and insurance carrier start building a defense before the injured person has left the hospital. Common trucking company defense tactics include pushing an early low settlement, classifying the driver as an independent contractor to limit vicarious liability, and disputing the severity of injuries before treatment is complete.
The insurance company is already working against you. Their adjusters are trained to minimize payout on every claim. At Sam Aguiar Injury Lawyers, we know their playbook. Our Bigger Share Guarantee® means you always walk away with more than we do after all bills, liens, and costs are paid.
Frequently Asked Questions
Who is typically liable in a Kentucky trucking accident?
Trucking accident liability in Kentucky can include the truck driver, the motor carrier, a freight broker, the shipper, a maintenance company, and the vehicle or parts manufacturer. Under KRS 411.182, Kentucky’s pure comparative fault law, each party is assigned a fault percentage, and each pays its proportionate share of damages. Identifying all liable parties is critical to maximizing recovery.
What FMCSA regulations define the standard of care in trucking cases?
The Federal Motor Carrier Safety Regulations set enforceable standards for drivers and carriers. Key rules include 49 CFR Part 391 (driver qualifications), 49 CFR Part 395 (hours-of-service limits), and 49 CFR Part 396 (vehicle maintenance). Violations of these rules are treated as strong evidence of negligence in Kentucky courts.
Can a freight broker be held liable for a trucking accident in Kentucky?
Freight broker liability is an evolving area of law. The U.S. Supreme Court heard arguments in Montgomery v. Caribe Transport II, LLC in March 2026, addressing whether state negligence claims against brokers survive federal preemption under the FAAAA. Some circuits already permit such claims under the Act’s motor vehicle safety exception. A ruling is expected by summer 2026.
How does Kentucky’s pure comparative fault law work in a trucking case?
Under KRS 411.182, Kentucky assigns a fault percentage to every party, including the injured person. Your total damages are reduced by your own share of fault, but you can still recover even if you are more than 50% at fault. This makes it important to identify every negligent party so each one pays a proportionate share of the total verdict or settlement.
Can a shipper be liable if the cargo was improperly loaded?
Yes. Under 49 CFR Part 393, Subpart I, cargo must be properly secured, distributed, and within legal weight limits. When a shipper overloads a trailer, understates cargo weight on the bill of lading, or improperly balances freight that later shifts and causes a crash, the shipper can be named as a defendant alongside the driver and carrier.
What evidence is needed to prove negligent hiring against a trucking company?
To prove negligent hiring in a trucking case, you must show the company failed to comply with 49 CFR 391.23’s requirement to investigate a driver’s 10-year employment history, safety violations, and drug-test record. The carrier’s driver qualification file, MVR checks, and pre-employment screening results are the core documents used to establish whether they met the federal standard.
What if the accident was caused by a defective truck part?
Product liability law allows claims against the part’s manufacturer when a design flaw or manufacturing defect causes a crash. Common defective components include brake systems, tires, steering assemblies, and trailer couplings. Under strict product liability, you do not need to prove the manufacturer knew about the defect. You need to show the defect existed and caused the accident. The maintenance company may also share liability if the defect was visible during scheduled servicing.
How quickly does evidence disappear after a Kentucky trucking crash?
Critical evidence can be lost or overwritten within days. Electronic logging device (ELD) data may be overwritten within 30 days. Event data recorder (black box) files require immediate preservation requests. Driver logs and carrier dispatch records are subject to federal retention minimums, but insurers begin building defenses immediately. See our page on preserving trucking evidence for the full picture.
