A single truck crash can involve multiple liable parties, including the truck driver, the motor carrier, the freight broker, and the company that loaded the cargo. The Federal Motor Carrier Safety Administration (FMCSA) regulates the trucking industry at the federal level, and when a carrier, driver, broker, or shipper violates those duties, the violation becomes evidence of negligence.

Federal Duties and Negligence

Truck crashes have more liable parties than car crashes because federal regulations assign separate duties to carriers, drivers, brokers, shippers, and maintenance providers. When one of those parties violates its duties, the violation becomes evidence of negligence in a Kentucky personal injury case.

Truck Driver

The driver is the most obvious party in any truck crash. Driver negligence includes speeding, distracted driving, driving under the influence, and hours-of-service violations that lead to fatigue.

Motor Carrier

The motor carrier is the company that holds the operating authority to transport freight. Under Kentucky’s respondeat superior doctrine, an employer is liable for a driver’s negligent acts performed within the scope of employment, so the carrier is usually a defendant even when the driver was at fault.

Under 49 CFR Part 387, motor carriers must maintain minimum insurance coverage of $750,000 to $5 million depending on the cargo type, with the highest limits applying to certain hazardous materials. That coverage typically responds to the carrier’s liability for its driver.

Freight Broker

A freight broker who assigns a load to a carrier with a poor safety record, multiple out-of-service violations, or inadequate insurance may be liable for negligent selection. The FMCSA Safety Measurement System (SMS) publishes carrier safety scores that brokers are expected to check before booking a load. The Supreme Court’s 2026 decision on freight broker liability after a truck crash held that federal law does not preempt these negligent selection cases.

Shipper and Cargo Loading Company

A shipper that loads cargo improperly or misrepresents its weight can be liable for a resulting rollover or spill. FMCSA cargo securement rules under 49 CFR Part 393, Subpart I set specific requirements for how different types of cargo must be secured, covering everything from lumber and metal coils to machinery and sealed containers.

Maintenance Provider

A maintenance provider can be liable when deferred or faulty repairs contribute to a crash. FMCSA regulations require carriers to keep detailed maintenance and inspection records for every vehicle. These records show who performed each repair, what work was done, and when the next inspection was due, and in litigation they can reveal a pattern of deferred maintenance.

Inspection Report Trail

Every commercial truck must undergo an annual inspection under 49 CFR Part 396, and drivers must complete inspection reports on their vehicles. These documents record when safety problems were discovered and whether they were fixed.

Truck Owners and Leasing Companies

Under the FMCSA leasing regulations (49 CFR Part 376), the motor carrier that holds the operating authority assumes full responsibility for the operation of any leased equipment. The carrier’s insurance applies even when someone else owns the truck. Coverage questions in these cases are covered in more detail in an overview of truck accident injury cases.
