Liability in Tractor-Trailer Crash Claims Explained

Unlike many car crashes, a semi-truck crash often involves several potentially responsible parties. The driver, the trucking company, the trailer owner, the shipper that loaded the freight and the maker of a failed part may all play a role. Identifying every responsible party is an early job for a truck accident lawyer, because each party may https://truckaccidentlawyers.wiki/topics/directory-methods/ carry its own insurance.
The truck driver
Most claims start with the driver's conduct, such as speeding, following too closely, unsafe lane changes, distraction, impairment or fatigue. Commercial drivers must hold a commercial driver's license (CDL) under 49 CFR Part 383 and must follow the driving rules in 49 CFR Part 392, which include limits on texting and hand-held phone use. A violation of a safety rule does not prove fault on its own, but in many states it can serve as evidence of negligence, and some states treat it as negligence per se. A truck wreck lawyer compares the driver's conduct against these rules.
Liability of the trucking company
If the driver is an employee working within the scope of the job, the trucking company is generally answerable for the driver's negligence under vicarious liability, sometimes called respondeat superior. The company may also face direct claims based on its own conduct, including negligent hiring, negligent retention, negligent supervision and negligent entrustment. Under the Federal Motor Carrier Safety Regulations, a trucking company must keep a driver qualification file under 49 CFR Part 391, run drug and alcohol testing under 49 CFR Part 382, and inspect, repair and maintain its trucks under 49 CFR Part 396. Missing or incomplete records can support a direct claim against the company, and the driver qualification file is often among the first documents a tractor-trailer accident lawyer requests.
Leased trucks and owner-operators
Many owner-operators lease their trucks to a trucking company. The leasing rules in 49 CFR Part 376 require the lease to give the trucking company exclusive possession, control and use of the equipment during the lease, which can matter when the company argues the driver was an independent contractor. The USDOT number and name marked on the cab, the bill of lading and the lease itself help show which company was operating the truck. A truck crash attorney will usually request these documents early.
Other companies in the shipment
Cargo that shifts or falls can contribute to rollovers and jackknife crashes. The cargo securement rules in 49 CFR Part 393 set standards for tiedowns and load securement, and a shipper or loading company that controlled how the freight was loaded may share responsibility in some cases. Claims against a freight broker that arranged the shipment raise separate questions, including federal preemption, and the answer turns on the specific claim and facts.
Product defects and maintenance
If brakes, tires, steering parts or an underride guard fail because of a defect, the manufacturer may face a product liability claim. An outside repair shop that did faulty work may also be named. Separating a defect from poor maintenance usually means inspecting the parts before they are repaired or scrapped.
Insurance and shared fault
Federal financial responsibility rules in 49 CFR Part 387 require at least $750,000 in public liability coverage when for-hire interstate trucks with a gross vehicle weight rating of 10,001 pounds or more haul nonhazardous property, and certain hazardous materials require higher minimums. Most states use comparative negligence, which may reduce damages by the injured person's percentage of fault, while a few still follow contributory negligence. A semi-truck accident lawyer looks at all of the parties, since a single policy may not cover the full loss.
