Who’s Liable in a Commercial Truck Accident? Breaking Down Multi-Party Responsibility with a Truck Accident Attorney

The Selvin Law Firm, PLLC • August 13, 2025

Commercial truck accidents are rarely open-and-shut cases. Unlike typical car crashes, these collisions can involve a web of companies, contractors, and service providers—all of whom might share some level of legal responsibility. If you've been injured in a crash with a commercial truck, figuring out who’s at fault is not always obvious. This is where hiring an experienced truck accident attorney becomes crucial.



At The Selvin Law Firm, we’ve spent over three decades helping truck accident victims across New York untangle the legal complexities of these high-stakes cases—and win. In this article, we’re going to walk you through the intricacies of multi-party liability in truck crashes, what makes these claims so challenging, and why the right legal team can make all the difference.

Why Truck Accident Liability Is Rarely Simple


When two cars collide, determining fault often comes down to the actions of the drivers involved. But commercial truck accidents are another story entirely. Trucks operate under strict federal and state regulations. Drivers are often working for larger companies, using leased equipment, or hauling cargo loaded by a third party. This opens the door to multiple potentially liable parties—each with their own insurance providers and legal teams.


And that’s not just a hypothetical. At The Selvin Law Firm, we've handled countless truck accident cases where it turned out the driver wasn’t the only one responsible. Sometimes it’s a negligent maintenance provider. Other times it’s the trucking company pushing drivers to meet unrealistic schedules, or even the manufacturer of a faulty part.


Understanding these layers takes more than just general legal knowledge—it takes focused experience. That’s why clients throughout New York trust our truck accident attorneys to navigate this complex legal terrain.


Common Liable Parties in a Truck Accident


In a commercial truck accident, it's not unusual to discover that several entities played a role in the crash. Here are the most common parties that may share liability:


1. The Truck Driver

This is often the first place investigators look. Driver fatigue, distracted driving, impaired operation, or speeding are leading causes of truck crashes. While the driver is directly responsible for their actions, they’re often just one piece of the puzzle.


2. The Trucking Company

Trucking companies have a legal duty to hire qualified drivers, maintain safe schedules, and ensure their vehicles are roadworthy. If they fail in any of these areas, they could be held liable. For instance, pushing drivers to exceed legal driving hours or skipping vehicle inspections can make them legally accountable.


3. Maintenance Providers

Many trucking companies outsource maintenance to third-party vendors. If a brake failure or tire blowout can be traced back to substandard work, those vendors may also bear responsibility.


4. Truck or Part Manufacturers

If a component of the truck—such as the steering system, brakes, or tires—fails due to a manufacturing defect, the maker of that part may be liable under product liability laws.


5. Cargo Loaders or Shipping Companies

Trucks carrying improperly loaded or unsecured cargo can become unstable and cause catastrophic accidents. If a third party was responsible for loading the truck, they may be named in a liability claim.


With this many potential defendants, having a skilled truck accident attorney on your side is essential. Our team investigates every angle to uncover who’s really at fault—and how best to hold them accountable.


Proving Liability—What Evidence Matters Most


Establishing who caused a truck accident isn’t just about pointing fingers. It requires hard evidence, meticulous investigation, and sometimes the use of expert testimony. At The Selvin Law Firm, we dig deep into the details. Here’s how we build our cases:


Key Types of Evidence:

  • Black Box Data (EDR): Modern commercial trucks have onboard systems that record speed, braking, and hours of operation. This can be critical in proving fatigue or negligence.
  • Driver Logs and Employment Records: These show whether a driver was working excessive hours or had a history of violations.
  • Maintenance and Inspection Records: If the truck was poorly maintained, these documents can reveal a pattern of neglect.
  • Dashcam or Surveillance Footage: Videos often capture the crash or events leading up to it.
  • Witness Statements and Police Reports: Eyewitness accounts and official documentation support the facts of the case.
  • Expert Analysis: We often consult accident reconstruction experts and medical professionals to illustrate exactly what happened—and the impact on your life.


Insurers know how powerful this evidence can be, which is why they move quickly to protect themselves. That’s why truck accident victims should never delay in contacting a legal team like The Selvin Law Firm. We’ll preserve key evidence and take over communication before the other side tries to spin the facts.


How Shared Liability Affects Compensation


New York follows a comparative fault system, which means multiple parties can share responsibility—and victims can still recover damages even if they were partially at fault.


How Comparative Fault Works:

Let’s say a truck driver is 70% responsible for a crash and a cargo loader is 30% responsible. If your total damages are $500,000, you can pursue claims against both parties. Even if you’re found to be 10% at fault yourself, you could still recover $450,000.


But these calculations aren’t automatic. Insurers will attempt to shift blame wherever they can—to reduce what they have to pay. They may claim you were driving recklessly or not wearing a seatbelt. That’s why having an experienced truck accident attorney near you is essential to protect your compensation and ensure your share of the fault is minimized or eliminated altogether.


Real-World Examples of Multi-Party Truck Accident Cases


While we can’t disclose client details, here are some anonymized examples that illustrate how liability can play out:


Case 1: Fatigued Driver + Negligent Trucking Company

A truck rear-ended our client’s vehicle during morning rush hour. The driver admitted to falling asleep at the wheel. Upon investigation, we found the company had been falsifying driver logs to meet tight delivery schedules. Both the driver and the company were held liable, and our client recovered over $900,000.


Case 2: Faulty Brakes + Maintenance Company

In another case, a delivery truck failed to stop at a red light due to faulty brakes. Our investigation revealed that the truck had been serviced just two weeks prior, and the maintenance company had overlooked critical repairs. We pursued claims against the maintenance provider and won a high six-figure settlement.


Case 3: Improper Cargo Loading

A truck tipped over on a highway curve, spilling cargo across multiple lanes. While the driver was initially blamed, our review of loading documents showed a third-party logistics company had overloaded the trailer and failed to secure it. This shifted liability and allowed our client to recover full compensation.


The takeaway? Liability isn’t always obvious. That’s why working with a firm like The Selvin Law Firm can significantly change the outcome of your case.


What to Do If You Suspect Multiple Liable Parties


If you or a loved one has been involved in a truck accident and you suspect more than one party is at fault, here’s what to do:


1. Seek Medical Attention Immediately

Even if injuries seem minor, a full medical record is critical for your case.


2. Document the Scene

Take photos, get witness info, and file a police report.


3. Don’t Talk to Insurance Adjusters Alone

They are trained to protect their company’s bottom line—not your interests.


4. Consult a Truck Accident Attorney Right Away

The sooner you get legal representation, the better your chances of uncovering all liable parties. At The Selvin Law Firm, we handle the entire process—from evidence collection to negotiating with multiple insurers.


You Don’t Need to Untangle Liability Alone


Truck accident cases are complex, especially when more than one party is responsible. Victims often face pushback from powerful insurance companies, multi-billion-dollar trucking operations, and layers of legal red tape. But you don’t have to face it alone.


With over 30 years of experience, The Selvin Law Firm is built to handle the most challenging truck accident cases in New York. We identify every liable party, calculate the full extent of your damages, and fight relentlessly to secure the compensation you deserve.
