In most California truck accidents, both the driver and the trucking company can be held liable, and both are usually named in the same lawsuit. The company is typically responsible for an employee-driver's negligence on the job, and it can also be directly liable for its own failures, such as negligent hiring or poor maintenance. Other parties, including trailer owners, cargo loaders, and maintenance contractors, may share responsibility too.
Crashes with big rigs and commercial delivery vehicles are frighteningly common. More than 5,300 people died in large-truck crashes nationwide in 2024, according to the Insurance Institute for Highway Safety, and NHTSA data shows California consistently ranking second in the nation for fatal large-truck crashes. When the medical bills start arriving, injured people want to know whom to pursue. The good news is that California law rarely forces you to pick just one.
Why Truck Cases Usually Involve More Than One Defendant
A typical fender-bender involves one driver and one insurer. Commercial trucking is different. A single truck on the road may involve:
- The driver, employed by or contracted to a motor carrier
- The trucking company that operates and often owns the tractor
- A separate company that owns the trailer
- A freight broker that arranged the load
- A contractor responsible for maintenance, including brakes and tires
- The shipper or loader that packed and secured the cargo
Any of them may share fault. Picture a big rig swinging wide out of an industrial yard near Vernon and clipping a sedan stopped at a light. The driver is hauling for a mid-size carrier out of the Inland Empire and runs that same route many times a month. A careful investigation goes well beyond the turn itself:
- Driver logs: Had he been on the road longer than federal rules allow?
- Dispatch records: Did the carrier's scheduling push him to skip breaks?
- Location history: Have there been similar wide-turn problems at that exit?
The driver made the turn, but the company may have set him up to fail. That is why injury attorneys in California usually name both the driver and the trucking company from the start. Doing so keeps every option open as the evidence develops, and it avoids being limited to one driver's resources when the company likely has much more coverage.
Why the Trucking Company Matters Most Financially
The blunt reality is money. A truck driver's personal auto policy, if it applies to work driving at all, rarely comes close to covering catastrophic injuries.
Under federal requirements, interstate carriers hauling general freight must carry at least $750,000 in liability coverage, and carriers hauling certain hazardous materials must carry up to $5 million. Many carriers carry more than the minimum.
That difference matters. An individual driver typically can't pay for a spinal cord injury, months of lost income, and years of rehabilitation. A trucking company backed by commercial insurance usually can. A court judgment is only as valuable as the money available to pay it.
The Paper Trail Can Reveal Company-Wide Problems
Trucking is one of the most heavily documented industries on the road. Driver logs, maintenance records, hiring files, and dispatch messages can reveal problems that go beyond one bad decision, such as a company that routinely overworked its drivers or deferred repairs to keep trucks moving.
Respondeat Superior: When the Company Answers for the Driver
California applies the doctrine of respondeat superior, Latin for "let the master answer." An employer is responsible for an employee's negligence when the employee is acting within the scope of the job. In trucking, if the driver was on duty, whether hauling a load or driving to a pickup, the company is financially responsible for the driver's negligence.
You don't have to prove the company itself did anything wrong. You don't need to show that dispatch knew the driver was speeding or ignored a complaint. The employment relationship and the fact that the driver was working are enough.
When the Company Is Directly Liable for Its Own Negligence
Respondeat superior isn't the only route. A trucking company can also be sued for its own negligence, separate from anything the driver did. Common direct claims include:
- Negligent hiring: putting a driver with a poor safety record, suspended license, or history of violations behind the wheel.
- Negligent retention: keeping a driver on after learning of unsafe behavior, a failed drug test, or repeated close calls.
- Negligent entrustment: giving a truck to a driver the company knew or should have known was unfit to operate it.
- Unsafe scheduling: pressuring drivers to skip required rest or falsify hours-of-service logs to meet deadlines.
- Poor maintenance: skipping required brake, tire, or safety inspections when a mechanical failure caused or contributed to the crash.
Because these claims focus on the company's conduct, they can stand on their own, even in a case where it's disputed whether the driver was technically on the clock.
The "Independent Contractor" Defense
One of the first moves a trucking company often makes is to claim the driver wasn't its employee but an independent contractor. If that argument succeeds, respondeat superior doesn't apply and the company tries to limit its exposure.
This comes up constantly with owner-operators, drivers who own their trucks and lease their services to a carrier. On paper they look independent. In practice, many:
- Drive only for one carrier
- Display that carrier's name and use its dispatch system
- Follow routes and delivery windows the carrier assigns
- Can't take other work without the carrier's permission
How California Courts Look Past the Label
California courts don't simply accept the title on a contract. They look at how much control the company actually had:
- Who set routes and schedules?
- Who owned the trailer and the cargo?
- Who set safety rules and procedures?
- Whom did the driver report to day to day?
A company that dispatches its "contractor," dictates delivery times, and requires its branding on the equipment often looks like an employer in practice, whatever the paperwork says. This is one of the most contested issues in California truck litigation, and it is why the actual working relationship has to be investigated rather than assumed.
When the Driver May Be the Only Defendant
In some situations, the company may not be liable for the driver's conduct:
- The driver was truly off duty, using the truck for a personal errand unrelated to work.
- The driver is a genuine owner-operator who sets their own routes and had no controlling relationship with a carrier for that trip.
- The driver committed an intentional or criminal act completely outside the scope of the job, such as driving drunk on a personal trip.
Even then, the facts deserve a close look. A "personal errand" sometimes turns out to be a delivery run, and a supposedly independent arrangement sometimes involves far more company control than the contract admits. Direct negligence claims, such as negligent entrustment, may also still apply.
The Evidence That Proves Who Is Liable
Establishing liability in a truck case requires much more than the police report. Key evidence includes:
- Electronic logging device (ELD) and event data recorder data: speed, braking, and hours of service around the time of the crash.
- Driver qualification file: hiring records, drug and alcohol testing, and past violations.
- Maintenance and inspection records: whether required inspections were done on schedule.
- Dispatch and communication records: whether the company pushed the driver to meet an unrealistic deadline.
- Bills of lading and weight records: whether the truck was overloaded or improperly loaded.
Trucking companies and their insurers often send response teams to serious crash scenes within hours, and they are gathering evidence to protect the company. Evidence that helps you can disappear just as quickly unless someone acts to preserve it. An accident reconstruction analyst can turn this data into a clear account of what happened and who caused it.
What If You Were Partly at Fault?
California follows pure comparative negligence. If you share some responsibility, for example by following a little too closely, you can still recover; your damages are reduced by your percentage of fault. If a jury finds you 15% responsible, you can still recover 85% of your damages from the driver, the company, or both.
Insurers know this rule well, and one of the most common insurance adjuster tricks is pushing as much fault onto you as possible. Our founding attorney, Shawn Rokni, previously worked as a senior insurance defense attorney and in-house counsel for a major auto insurer, and he has seen how carriers use fault arguments to shrink what they pay. Sharing some of the blame does not mean you don't have a case.
Deadlines: California's Statute of Limitations
Under California Code of Civil Procedure section 335.1, you generally have two years from the date of the crash to file a personal injury lawsuit. If a government entity may be responsible, such as a public agency that maintains the road or operates a municipal vehicle, a formal claim usually must be filed within six months.
Two years can sound like plenty of time, but evidence disappears much faster. Rain erases skid marks, businesses record over security footage, and under federal rules carriers are only required to keep drivers' records of duty status for six months. Acting early allows your attorney to send preservation letters demanding that the company keep its records.
How Your Attorney Decides Whom to Sue
Choosing defendants starts with investigation: pulling the driver's employment records, the truck's maintenance and inspection history, the black box data, and the contracts connecting the driver to every company involved with the truck and its cargo. The evidence then points to the right parties. If the driver was speeding, the driver and the company. If the brakes failed, possibly the maintenance contractor. If shifting freight caused a rollover, the loader. The goal isn't to sue everyone in sight; it's to hold the parties who actually caused your injuries responsible.
Before accepting any settlement, remember that once you sign a release, you generally can't reopen the claim if your injuries turn out to be worse than expected. To understand what a claim may include, see our guides to truck accident damages and how much truck accident settlements are worth.
