Who Is Liable in a Tractor-Trailer Crash?

Liability in Commercial Truck Crash Claims Explained

A crash involving a tractor-trailer often has more than one responsible party. 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. Working out who is legally responsible is an early task for a truck accident attorney, because each responsible party may have separate insurance.

Claims against the driver

The starting point is usually 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 safety violation does not prove fault by itself, but in many states it can be evidence of negligence, and some states apply negligence per se. A truck accident attorney will compare the driver's conduct with these rules.

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. The Federal Motor Carrier Safety Regulations require a driver qualification file under 49 CFR Part 391, drug and alcohol testing under 49 CFR Part 382, and systematic inspection, repair and maintenance under 49 CFR Part 396. Gaps in those 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.

When the driver owns the truck

Some drivers are owner-operators who 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 for the lease term, which can matter if the company says 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 accident attorney will usually request these documents early.

Shippers and freight brokers

Cargo that shifts or falls can contribute to rollovers and jackknife crashes. The cargo securement rules in 49 CFR Part 393 set requirements for tiedowns and securing loads, and in some cases a shipper or loading company that controlled the loading may share responsibility. Claims against a freight broker that arranged the shipment raise separate questions, including federal preemption, and the answer depends on the claim and the facts.

Product defects and maintenance

When brakes, tires, steering components or an underride guard fail because of a defect, the manufacturer can face a product https://lukaslctn085.image-perth.org/tractor-trailer-crash-statistics-fmcsa-and-nhtsa-figures liability claim. A maintenance contractor that performed faulty repairs can also be named. Separating a defect from poor maintenance usually means inspecting the parts before they are repaired or scrapped.

How fault and insurance fit together

Under 49 CFR Part 387, for-hire interstate trucks with a gross vehicle weight rating of 10,001 pounds or more that haul nonhazardous property must carry at least $750,000 in public liability coverage, and higher minimums apply to certain hazardous materials. Most states apply comparative negligence, which may reduce damages by the injured person's percentage of fault, while a few still apply contributory negligence. A semi-truck accident lawyer looks at every party because one policy may not cover the full loss. This is general information rather than legal advice, and it does not predict the result of any claim.
