Who Is Liable in a Truck Accident?

Unlike car accidents, truck crashes often involve multiple liable parties — each with their own insurance coverage. Finding every source of compensation is how we maximize your recovery.

How Do FMCSA Regulations Create Liability?

The Federal Motor Carrier Safety Administration (FMCSA) sets strict rules governing commercial truck operations. When these rules are violated, they create powerful evidence of negligence.

Cross & York attorneys know every FMCSA regulation — from hours-of-service limits to drug testing requirements — and we know exactly how to use violations to win your case.

Key FMCSA Regulations

✓Hours of Service: max 11 hrs driving per 14-hr shift
✓Mandatory 30-min breaks after 8 hours driving
✓Electronic Logging Device (ELD) requirements
✓Annual vehicle inspection requirements
✓Pre-employment drug & alcohol testing
✓Blood alcohol limit: 0.04% (half of car driver limit)
✓Medical certification requirements for CDL holders

Who Can Be Held Liable in a Truck Accident?

Truck Driver Liability

If the driver was speeding, fatigued, impaired, distracted, or violated FMCSA hours-of-service rules, they bear direct personal liability. Their driving record and compliance history become critical evidence.

Drowsy driving beyond legal hours

Distracted driving / cell phone use

DUI / drug impairment

Speeding or reckless driving

Trucking Company Liability

Under the legal doctrine of respondeat superior, trucking companies are liable for their employees' actions. Beyond vicarious liability, carriers face direct liability for negligent hiring, training, and supervision.

Negligent hiring of unqualified drivers

Pressuring drivers to exceed hours limits

Inadequate safety training

Ignoring known vehicle defects

Cargo Loading Companies

When improperly loaded or secured cargo causes an accident — through weight imbalance, shifting loads, or falling debris — the cargo loading company bears direct liability regardless of who was driving.

Overloaded trucks exceeding weight limits

Improperly secured cargo

Cargo that shifts during transit

Hazardous materials violations

Truck Manufacturers

If defective truck components contributed to your accident — faulty brakes, tire blowouts, steering failures, or defective safety systems — the manufacturer may face product liability claims.

Defective brake systems

Tire manufacturing defects

Faulty trailer hitches

Defective underride guards

Government Entities

Poorly designed roads, missing signage, inadequate lighting, or dangerous road conditions may make a government entity partially liable. These claims have special notice requirements.

Dangerous road design

Missing or obscured warning signs

Poorly maintained roads

Inadequate lighting in high-risk areas

How Does Multi-Party Liability Work?

Illustrative Case Study (Fictionalized)

The Accident: A fatigued driver exceeds hours-of-service limits under pressure from his dispatcher. The company's cargo loaders have overloaded the trailer. Defective brakes — flagged in maintenance logs but never repaired — fail on a highway, causing a catastrophic collision.

Liable Parties Identified: The driver (fatigue, HOS violation), the trucking company (negligent dispatch, failure to maintain brakes), the cargo loading company (overloaded trailer), and the brake manufacturer (defective product).

The Result: By pursuing all four liable parties across their combined insurance coverage, our client recovered significantly more than would have been possible against any single defendant.

Who can be held liable for a truck accident?

Depending on the facts, liability can rest with the truck driver, the trucking company (motor carrier), the shipper or cargo loader, a maintenance contractor, the manufacturer of a defective part, and sometimes a freight broker or a government body responsible for the road. Identifying every responsible party matters because each may carry separate insurance.

Is the trucking company responsible for its driver's mistakes?

Usually, yes. An employer is generally liable for an employee driver's negligence while on the job, and a carrier can also be directly liable for negligent hiring, training, supervision or maintenance. Federal leasing rules (49 CFR 376.12) generally treat a truck operating under a carrier's authority as under that carrier's control, even when the driver is an owner-operator.

What federal rules apply to truck drivers and trucking companies?

The Federal Motor Carrier Safety Administration sets rules on hours of service, drug and alcohol testing, driver qualifications, vehicle inspection and maintenance, and cargo securement. For example, property-carrying drivers may drive at most 11 hours after 10 consecutive hours off duty, within a 14-hour window (49 CFR 395.3). Breaking these rules can be strong evidence of negligence.

How do you prove a truck driver or trucking company was at fault?

Key evidence includes electronic logging device (ELD) records, engine control module data, dashcam footage, maintenance and inspection records, the driver's qualification file, the police report, witness statements and accident reconstruction. Carriers only have to keep hours-of-service records for six months (49 CFR 395.8), so a preservation letter should be sent quickly.

Can I sue both the truck driver and the trucking company?

Yes. Truck accident claims commonly name the driver, the carrier and any other responsible party in the same case. Doing so makes every applicable insurance policy available and stops defendants from shifting blame to someone who is not part of the claim.
