Liability in Tractor-Trailer Crash Claims Explained

Filed by @devinhplh591
Who Can Be Held Responsible for an 18-Wheeler Crash?

A crash involving a tractor-trailer often has more than one responsible party. The driver, the trucking company, the owner of the trailer, the company that loaded the cargo and the manufacturer of a defective part can each play a role. Identifying every responsible party is an early job for a truck accident lawyer, because each responsible party may have separate insurance.

The driver's conduct

The starting point is usually the driver's conduct, such as speeding, following too closely, unsafe lane changes, distraction, impairment or fatigue. Commercial drivers need a commercial driver's license (CDL) under 49 CFR Part 383 and 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 accident attorney will compare the driver's conduct with these rules.

Why the trucking company is usually a defendant

When the driver is an employee acting within the scope of employment, the trucking company is usually responsible for the driver's negligence under vicarious liability, also known as 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.

Owner-operators and leased trucks

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 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. An 18-wheeler accident attorney typically requests these documents early.

Cargo loaders and freight brokers

Shifting or falling cargo can contribute to rollovers and jackknife crashes. The cargo securement rules in 49 CFR Part 393 set standards for tiedowns and load securement, and in some cases a shipper or loading company that controlled the loading may share responsibility. A freight broker that arranged the load raises 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. Telling a defect apart from poor maintenance usually requires inspecting the parts before they are repaired or scrapped.

Insurance and shared fault

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 use comparative negligence, which can reduce damages by the injured person's share 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.
