Ever wondered why a truck crash case almost never stops with the driver?
And there’s good reason for that. When an 80,000 pound rig drifts over the centre line the driver rarely ends up paying for it alone. The company who hired him, trained him and pushed him to make a delivery window is usually standing right beside him.
That rule has a name. It’s called vicarious liability.
And this is the primary reason truck claims are so different from regular auto claims.
Here’s how it works…

What Is Vicarious Liability?
The doctrine of vicarious liability imposes liability on employers for the acts of their employees.
No one’s arguing the corporation was driving negligently. They didn’t run a red light or fall asleep behind the wheel at 2am. But since their employee was on the clock when it occurred, the law deems his negligence was the corporation’s negligence as well. This doctrine is known as respondeat superior — fancy Latin that basically means “let the master answer.”
Why does that matter so much? Two reasons: accountability and insurance.
Your driver could have a small personal policy that is gone after a week of hospital bills. His motor carrier has $ millions of commercial coverage they are required to carry. That difference is why a truck accident lawyer investigates the logo on the door before the guy in the cab. It’s also why a professional truck accident law firm sends preservation of evidence letters to the carrier days after a crash. A truck accident lawyer that only sues the driver just missed the ball. They left the defendant home alone.
Pretty important distinction, right?
Why Trucking Companies Get Pulled Into The Claim
The numbers explain the pressure here better than any legal theory can.
The federal government reports 5,340 people died in 2024 due to crashes involving large trucks. 62% of them were occupants of regular passenger vehicles — not the truck. Also, 161,201 people suffered injuries in crashes that year.
These aren’t parking lot fender benders. They are life-changing events.
And here’s the part most people miss…
Jurors have seen it. Awards against motor carriers have skyrocketed. The median verdict hit $36 million for largest verdicts in 2022. Carriers realize this. Their insurers realize it as well.
Which is why they fight vicarious liability from the very first phone call.
Scope Of Employment Is The Whole Ball Game
The doctrine of vicarious liability only applies if the driver was acting within the “scope of employment” at the time of the accident.
That sounds complicated. It isn’t.
Driving to pick-up freight, picking up freight, delivering freight and anything else your company requires him to do — he’s working. Activities that remain within scope:
- Driving a scheduled route or dispatch assignment
- A short detour for fuel, food or a required rest break
- Backing into a customer’s loading dock
- Repositioning an empty trailer between yards
What doesn’t count? A driver who drives the rig 60 miles in the wrong direction to run a personal errand. Or steals the truck while he’s off work. That’s known as a “frolic.” Carriers love that word because it allows them to walk away.
They will likely use that excuse. Dispatch records, GPS signals and fuel logs typically prove otherwise.
The Independent Contractor Argument
Here’s the favourite defence in the trucking world.
The carrier will argue that the driver was never an employee anyway. He drove his own truck, they will say. So he is solely responsible for his errors. Sound argument?
Not quite.
Federal regulations hold interstate motor carriers accountable for every vehicle operating under their authority, regardless if the driver is company employed or leased on. When that truck is rolling around with the company DOT number, and moving pursuant to the company dispatch, that “Contractor” title becomes very tenuous.
Documentation is not determinative. Who dictated the hours of the worker? Who decided the route to be driven? Could he be fired at will?
Vicarious Liability vs Direct Negligence
This is where truck cases get interesting.
Vicarious liability holds the company liable for the driver’s actions. Direct negligence holds the company liable for its own actions. The best cases contain both. Because they stack. These are the three most common.
Negligent Hiring
Drivers records, previous employers, drug screens and licence should be verified by carriers before giving someone a set of keys.
Many don’t. Driver shortage causes cutting corners. Cutting corners leads to hiring folks with previous violations driving 40 tons of steel. When the file reads a manager waved a driver with 3 prior collisions through it’s no longer the drivers fault.
Negligent Training And Supervision
A commercial licence is a starting point, not a finish line.
Companies are expected to train drivers on the equipment they drive, enforce hours-of-service compliance and suspend drivers who rack up violations. When a carrier disregards speeding alerts for eight months and then the driver clips a minivan… you’ve got your pattern.
Negligent Maintenance
Brakes, tyres, lights and coupling devices need inspection and repair on a schedule.
Deferred maintenance only seems inexpensive. Reporting the same thing for defect, cleared, defect, cleared three times is horrible to a jury.
The Evidence That Ties A Company To The Crash
Each of these theories rises or falls on documents. The majority of those documents are maintained in the trucking company’s file room.
Time is of the essence. Certain records can be legally discarded after six months. Evidentiary data stored on the engine control module can be overwritten in a matter of days once the truck is back in service. That’s why the first step is always a letter advising the company to preserve all evidence.
The material worth chasing includes:
- Electronic logging device records showing hours behind the wheel
- The driver qualification file with the application, licence history and prior employer checks
- GPS data indicating location of truck and who dispatched it there
- Maintenance and inspection reports for the tractor and the trailer
- Drug and alcohol testing results taken after the crash
- The lease agreement between the carrier and the owner-operator
If those two pieces of land fall next to each other, the rest of the story writes itself. A truck driver 14 hours into his shift driving a truck with an illuminated brake defect wasn’t trying to ruin someone’s day. He was acting exactly how his environment was designed to make him act.
Bringing It All Together
Vicarious liability is a simple idea buried under a difficult name.
Companies make money from drivers’ miles, so they’re responsible for what those miles do. That’s just business. And that’s why a significant truck crash claim targets the boardroom, not just the cab.
To quickly recap:
- The driver’s mistake becomes the company’s mistake when he’s on the job
- “Independent contractor” labels rarely survive a look at who really had control
- Direct negligence claims like bad hiring and skipped maintenance stack on top
- The proof lives in company records that can vanish in months
If you’ve been involved in a big rig accident, file that paperwork yesterday. The trucking company has already retained counsel. They started work on your case the day of the accident.
