Truck & 18-Wheeler Accidents

California 18-Wheeler & Commercial Truck Accident Lawyer

Hit by an 18-wheeler? You're up against a company, an insurer, and a countdown. A loaded semi can weigh 20 to 30 times what your car does — and the people on the other side of your claim know it.

Trucking companies dispatch investigators within hours, while the evidence that proves your case starts disappearing. Kocaj Law, P.C. moves fast to preserve it, uses the federal safety rules against them, and holds every responsible party accountable.

A truck crash is a different kind of fight. The injuries are more severe, the insurance policies are far larger, and the other side is not just an individual driver — it's a trucking company with its own lawyers and a financial interest in paying you as little as possible. Commercial drivers and the companies behind them are bound by a detailed body of federal safety rules — the Federal Motor Carrier Safety Regulations — and when they break those rules, that can be powerful proof of fault.

Cases we take

What we handle

Each fact pattern is investigated with the same intensity — whether it settles before suit or proceeds through trial and appeal.

Driver fatigue & hours-of-service

Drivers pushed past federal limits on time behind the wheel — one of the leading causes of truck crashes.

Speeding & driving too fast for conditions

Federal rules demand extreme caution in rain, fog, and ice — a higher standard than California's basic speed law.

Impaired & distracted driving

Commercial drivers face a stricter 0.04% alcohol limit and mandatory drug testing — violations that can establish fault.

Poor maintenance & equipment failure

Bad brakes, worn tires, and skipped inspections that violate the maintenance rules carriers are required to follow.

Unsafe or shifting cargo

Loads that were overweight, poorly distributed, or improperly secured — causing rollovers and lost loads.

Negligent hiring & unqualified drivers

Companies that skip the required background checks and put unsafe or unqualified drivers on the road.

Why this matters

The stakes are real.

The proof of what really happened — electronic logging data, the truck's black box, the driver's logs and qualification file, inspection and maintenance records — sits in the trucking company's control. Some of it is only required to be kept for limited periods, and a truck can be repaired or back on the road within days.

That's why one of the first things we do is send a formal demand to preserve this evidence, before it can be overwritten, repaired, or quietly lost. Waiting can cost you the very records that prove your case. A truck crash usually has several potential defendants — the driver, the trucking company, freight brokers and vehicle owners, and the contractors who serviced the truck or loaded its cargo — and finding all of them can be the difference in your recovery.

FAQ

Frequently asked questions

How is a truck accident case different from a regular car accident?

In several big ways. Commercial truck drivers and trucking companies must follow a detailed set of federal safety rules — the Federal Motor Carrier Safety Regulations — that hold them to a higher standard than ordinary drivers. Breaking those rules can establish fault. Truck cases also usually involve more than one responsible party and far larger insurance policies, and they depend on evidence, like electronic logs, that can disappear quickly if it is not preserved.

Who can be held responsible for an 18-wheeler crash?

Often more than just the driver. Depending on the facts, the trucking company can be liable for its driver's negligence and for its own failures — such as negligent hiring, inadequate maintenance, or pushing drivers past legal limits. Brokers, owners of the truck or trailer, maintenance contractors, and cargo loaders may also share responsibility.

What federal rules apply to truck drivers and trucking companies?

The Federal Motor Carrier Safety Regulations govern things like hours of service, driver qualifications and background checks, drug and alcohol testing, vehicle inspection and maintenance, and cargo securement. A violation can be used to show the driver or company was negligent, and the records that prove compliance — or non-compliance — are central evidence in the case.

Why is it urgent to act quickly after a truck crash?

Because the most important evidence can be gone in weeks. Electronic logging data, the truck's black box, driver logs, inspection and maintenance records, and the driver's qualification file are controlled by the trucking company, and some records only have to be kept for limited periods. Getting a lawyer involved early allows a formal demand to preserve that evidence before it's overwritten, repaired, or lost.

What if the truck driver was an "independent contractor"?

That label often doesn't get the trucking company off the hook. Under the federal regulations, a driver operating under a motor carrier's authority is generally treated as the carrier's employee for safety purposes, regardless of how the contract describes the relationship. Trucking companies can't simply avoid responsibility by calling their drivers independent contractors.

How long do I have to file a truck accident claim in California?

Generally two years from the date of the injury. But because critical trucking evidence can disappear long before that deadline, and because these cases involve multiple defendants and insurers, it's best to speak with an attorney as soon as possible after the crash.

What does it cost to hire a truck accident lawyer?

Kocaj Law, P.C. handles truck and commercial-vehicle cases on a contingency basis. The initial consultation is free and confidential, and you owe no attorney's fee unless we recover compensation for you.

How much is my 18-wheeler accident case worth in California?

There's no fixed number — value depends on the severity of your injuries, your medical bills (now and future), lost income and earning capacity, and the pain and disruption to your life. Commercial truck cases often involve larger recoveries than ordinary car crashes because the injuries are more serious and the policies are bigger. In egregious cases — like a carrier that knowingly put a dangerous driver or truck on the road — California law (Civil Code § 3294) also allows punitive damages. The only way to know your range is a case-specific evaluation.

How much insurance do commercial trucks carry?

Federal law requires interstate trucking companies to carry minimum liability coverage — typically $750,000 for general freight, and far more (often $1 million to $5 million) for trucks hauling hazardous materials. These policies are much larger than the minimums for passenger cars, which matters for victims with catastrophic injuries — but it also means the carrier and its insurer fight harder and earlier to limit what they pay.

What is negligence per se in a California truck accident case?

When a truck driver or trucking company violates a safety regulation designed to protect the public — for example, the federal hours-of-service limits or the duty to use extreme caution in bad weather (49 C.F.R. § 392.14) — and that violation causes the kind of harm the rule was meant to prevent, California treats the violation itself as evidence of negligence. In a 2005 case (Weaver v. Chavez), a California court confirmed that the higher federal standard of care, not just California's basic driving laws, governs commercial truckers. Proving a regulatory violation can make fault much clearer.

Can I still recover money if I was partly at fault for the truck crash?

Yes. California follows a 'pure comparative fault' rule, which means you can recover even if you were partly responsible — your compensation is simply reduced by your percentage of fault. So even if you're found 40% at fault, you can still recover 60% of your damages. Don't assume you have no case just because the trucking company blames you.

What is ELD and black box data, and why does it matter?

An Electronic Logging Device (ELD) automatically records a commercial driver's hours of service, and the truck's 'black box' (event data recorder) can capture speed, braking, and other data around the time of a crash. This is some of the most powerful evidence in a truck case — it can show fatigue, speeding, or hours-of-service violations. Carriers are only required to keep ELD backups for about six months, so a prompt legal demand to preserve this data is critical before it's overwritten.

Can the trucking company be held responsible for its driver's actions?

Usually, yes. Under California's respondeat superior doctrine, an employer is liable for a driver's negligence committed within the scope of employment. The company can also face direct liability for its own failures — negligent hiring, training, supervision, retention, or entrustment — such as putting an unqualified or dangerous driver behind the wheel. Holding the company accountable, not just the driver, often makes the difference in a serious case.

What are the most common causes of semi-truck and 18-wheeler accidents?

The crashes we see most often trace back to a broken safety rule: driver fatigue and hours-of-service violations, speeding or driving too fast for weather conditions, impaired or distracted driving, poor maintenance and equipment failures (bad brakes, worn tires), unsafe or shifting cargo, and negligent hiring of unqualified drivers. Identifying which rule was broken is central to proving the case.

What should I do after a semi-truck accident in California?

Get medical care right away, even if you feel okay — serious injuries can be masked by adrenaline. If you can, document the scene with photos, get the truck and trailer numbers and the carrier's name, and collect witness information. Avoid giving a recorded statement to the trucking company's insurer before speaking with a lawyer. Then contact an attorney quickly so a preservation demand can lock down the ELD, black box, and driver records before they disappear.
