Question 1 of 10 · nothing is sent until the last step
Who was injured in the big rig accident?
This helps us match you with the right attorney.
A California big rig accident lawyer — also called a big rig accident attorney or truck accident law firm — represents people injured in crashes with semi-trucks, 18-wheelers, and tractor-trailers. In California you have two years to file, fault is apportioned under pure comparative negligence, and compensatory damages are uncapped. Cases are governed by federal FMCSA rules and defended by insurers holding policies of $750,000 or more. Most attorneys work on contingency: free consultation, no fee unless you win.

Definitions
What is a big rig?
"Big rig," "semi," "18-wheeler," and "tractor-trailer" describe the same class of vehicle. The name changes by region; the law does not.
Big rig, defined
- A Class 8 heavy-duty truck: a tractor unit pulling one or more semi-trailers, with a gross vehicle weight rating above 33,000 lb.
- Loaded, it may weigh up to the 80,000-lb federal maximum — roughly 20 times a passenger car — and needs up to 40% more distance to stop.
- Operated by a driver holding a commercial driver's license (CDL) for a motor carrier registered with the U.S. DOT.
- When it crosses state lines it is regulated by the Federal Motor Carrier Safety Administration (FMCSA) under 49 CFR — hours of service, drug testing, maintenance, cargo securement, and minimum insurance.
The lawyer goes by many names too — big rig lawyer, big rig injury lawyer, big truck accident lawyer, trucking accident lawyer, trucking law firm, big rig accident law firm. They all describe the same specialty: a personal injury attorney who litigates against motor carriers after a big rig crash or wreck.
Each vehicle name carries its own evidence questions. Start with the guide that matches yours: 18-wheeler, semi-truck, tractor-trailer, or other commercial trucks such as box trucks, dump trucks, and tankers.
California
Where California big rig crashes happen — and what changes here
The Ports of Los Angeles and Long Beach feed drayage traffic across the Inland Empire, and the I-5 carries the state's north–south freight. Those corridors are where most California truck cases start.
California's heaviest truck corridors
- I-5 (the state's north–south freight spine)
- I-10 and I-15 through the Inland Empire
- SR-99 through the Central Valley
- I-710 (the Long Beach drayage corridor)
- I-40 and I-80 for interstate long-haul
What is different in a California truck case
- California does not cap compensatory damages in ordinary personal injury cases.
- Claims against a California public entity require a government claim, generally within six months of the incident under the Government Claims Act.
- The California Highway Patrol handles most freeway collision investigations; the traffic collision report is a core early document.
- California is a pure comparative state. Even a claimant found 90% at fault may recover the remaining 10% of their damages — there is no percentage that bars recovery outright.
Attorneys in the network handle big rig cases throughout California, including Los Angeles, San Bernardino, Rancho Cucamonga, Riverside, Fresno, Sacramento, Oakland, and San Diego.
Why it's different
Truck claims are not car claims
A loaded tractor-trailer weighs up to 80,000 pounds. The injuries are worse, the defendants are corporations, and the evidence lives in the truck's own computers.
Federal regulations set the standard of care
FMCSA rules govern driving hours (Part 395), driver qualification files (Part 391), drug and alcohol testing (Part 382), inspection and maintenance (Part 396), and cargo securement (Part 393). A documented violation is powerful evidence of negligence, and the electronic logging device (ELD) data and driver qualification file are where it is found.
Multiple parties may be liable
The driver, the trucking company (through respondeat superior and vicarious liability, or directly for negligent hiring, supervision, and entrustment), the trailer owner, the cargo loader, a maintenance contractor, a freight broker, even the manufacturer — each brings its own insurance policy. An independent contractor or owner-operator label does not end the carrier's exposure.
Evidence disappears in weeks
Event data recorder ("black box") downloads, electronic logging device (ELD) records, dashcam footage, and dispatch messages get overwritten fast. An attorney sends a spoliation letter immediately. What a semi truck records · What to do after a crash
Evidence that decides a big rig case
- Engine control module / event data recorder — speed, braking, throttle, and following distance in the seconds before impact
- Electronic logging device (ELD) records — the hours-of-service history that proves or disproves driver fatigue
- Driver qualification file — licensing, medical certification, training, and prior violations
- Post-crash drug and alcohol test results — required by federal rule after a fatal or injury crash with a citation
- Inspection and maintenance records — brake, tire, and annual inspection history
- Dispatch, telematics, and cell-phone records — schedule pressure and distraction
- Dashcam, traffic-camera, and facility CCTV footage — often on 30-day loops
- Police crash report, witness statements, and skid marks — the basis for accident reconstruction
- The carrier's FMCSA safety record — safety rating, CSA scores, prior violations, out-of-service orders, and crash history in the SAFER company snapshot
What you're hiring
What a big rig accident attorney actually does
Not paperwork. The first two weeks of a truck case decide what evidence exists a year later — and the carrier's rapid-response team is usually on scene the same day.
How to choose a big rig accident lawyer — 10 questions to ask →
1. Sends a spoliation (preservation) letter within days
A formal demand that the carrier keep the black box data, ELD logs, dashcam footage, and driver file. Without it, that evidence is routinely overwritten in weeks.
2. Identifies every defendant and every policy
USDOT and FMCSA SAFER records reveal the carrier, the trailer owner, the shipper, the broker, and the maintenance vendor — each with separate insurance.
3. Takes over all contact with the insurer
No recorded statements, no quick releases. The adjuster deals with your attorney, not you.
4. Retains the experts
Accident reconstruction, trucking safety standards, treating physicians, a life-care planner, and an economist to price future losses.
5. Documents the full damages picture
Future medical care, lost earning capacity, pain and suffering, and — where the conduct warrants it — punitive damages.
6. Negotiates, files suit, and prepares for trial
A demand package, mediation, and a filed complaint that compels the carrier to hand over its records. Most cases settle; trial readiness is what drives the offer.
Root causes
What causes big rig crashes
FMCSA data shows most serious truck accidents trace back to a handful of preventable failures — and the cause determines who you can hold accountable.
Crash types include rear-end and head-on collisions, sideswipes, T-bone and side-impact crashes, right-turn squeeze plays, lost or unsecured loads, hazmat spills and fires, and multi-vehicle pileups. All causes and crash types
Driver fatigue
Hours-of-service violations remain a leading cause of fatal crashes.
Jackknife accidents
A trailer swinging past the cab can sweep across multiple lanes.
Underride crashes
Among the deadliest collisions on any highway.
Rollover accidents
High center of gravity, cargo overload, and speed on curves.
Brake failure
Skipped inspections usually point to carrier negligence.
Tire blowouts
A failed tire on an 80,000-lb rig means loss of control.
Blind spot (no-zone) crashes
Lane changes and merges into the truck's blind zones.
Wide turn accidents
Right-turn squeeze plays that trap cars against the curb.
Cargo shift and lost loads
Improper securement under 49 CFR Part 393.
Impaired driving
Failed or skipped drug and alcohol tests under Part 382.
Don't sign the first offer — or give a recorded statement
The trucking company's insurer wants to close your claim for as little as possible — often before you know the full extent of your injuries. The adjuster may ask for a recorded statement or a quick release; you are not required to give either. Claimants who work with an attorney typically walk away with significantly more than those who negotiate alone, and a consultation costs nothing.

Injuries
The injuries these cases involve
A big rig wreck produces catastrophic injuries at a rate ordinary collisions do not — brain and spinal trauma, crush injuries, burns, disfigurement. Some — mild brain injury, chronic pain, delayed symptoms — are also the hardest to prove, which is why medical documentation from day one matters.
Traumatic brain injury (TBI)
Concussion through permanent cognitive impairment — and the injury insurers most often dispute.
Spinal cord injury and paralysis
Lifetime care costs that early offers never account for.
Amputation and crush injuries
Common in underride and rollover crashes.
Burn injuries
Fuel fires and hazardous cargo ignition.
Wrongful death
Funeral expenses, lost support, and loss of companionship for surviving family.
All truck accident injuries
Fractures, whiplash, internal injuries, herniated discs, PTSD — and which are hardest to prove.
Compensation
What your claim may cover
No honest source can quote your case's value from a web page — but these are the categories that drive it.
Average big rig accident settlements and what you keep →
Economic damages — medical care and property damage
Emergency treatment, surgery, rehabilitation, projected future medical care for catastrophic injuries, and property damage — vehicle repair or replacement.
Lost income and earning capacity
Wages missed during recovery, plus reduced ability to earn going forward — priced by a vocational expert and an economist in serious cases.
Non-economic damages, wrongful death, and punitive damages
Pain and suffering, mental anguish, loss of enjoyment of life, and loss of consortium. In fatal crashes, funeral expenses and lost support for surviving family. Where a carrier's conduct was reckless, punitive damages. How settlement value works

Real stories
What people say after checking their case
“The trucking company's insurer called before I'd even seen a doctor. I didn't know what my case was worth or what to say. Checking my options first made all the difference.”
“A semi-truck trailer hit my car and I was in the hospital for weeks. I wish I'd asked about a case review sooner instead of dealing with the adjuster alone.”
“I had no idea multiple companies could be responsible after a big rig accident — the driver, the carrier, even the loader. That changed how I thought about my claim.”
“I missed two months of work and the insurance offer didn't come close to covering it. Getting matched with an attorney who handles truck cases specifically mattered a lot.”

Questions people ask
Big rig accident lawyer FAQ
How much does a big rig accident lawyer cost?
Big rig accident lawyers work on contingency. The consultation is free, and the attorney fee — usually 33% to 40% of the recovery — is only paid if you win. If there is no recovery, you owe no attorney fee. Case costs such as expert witnesses are typically advanced by the firm and reimbursed from the settlement.
How much of my settlement will I actually keep after fees and medical liens?
Three things come out of a truck accident settlement before you are paid: the contingency fee, the case costs the firm advanced, and any medical liens held by hospitals, health insurers, Medicare, or Medicaid. On a $25,000 settlement with a 33% fee, $1,500 in costs, and $5,000 in liens, the net is roughly $10,000 — and a lawyer who negotiates the liens down can raise that materially.
What is the average settlement for a big rig accident?
There is no reliable published average. Truck accident settlements range from tens of thousands of dollars for moderate injuries to several million for catastrophic injury or wrongful death, because carriers must carry at least $750,000 in liability coverage and many carry $1 million to $5 million. Injury permanence, liability evidence, the number of defendants, and your state's fault rule drive the number.
Can I sue the trucking company, or only the driver?
Usually both. Under respondeat superior a motor carrier is liable for its employee driver's negligence, and it can be directly liable for negligent hiring, training, supervision, or maintenance. The trailer owner, cargo loader, freight broker, maintenance contractor, and parts manufacturer can also be defendants, each with its own insurance policy.
What if the truck driver was an independent contractor?
The carrier can still be liable. Federal regulations treat a driver operating under a carrier's USDOT authority as its statutory employee for many purposes, and courts look at control, not labels. Owner-operators also carry their own policies, which adds a defendant rather than removing one.
What if I was partly at fault for the crash in California?
You can still recover. California is a pure comparative negligence state: your compensation is reduced by your percentage of fault, but no percentage bars recovery outright — even a claimant found mostly at fault can recover the remainder. The carrier's insurer will still try to shift fault onto you, because every point it moves reduces what it pays.
How long does a big rig accident lawsuit take?
Cases that settle before suit can resolve in months. Filed cases commonly run one to three years through discovery, depositions, expert work, and mediation. Most settle before trial. The timeline is driven by how long it takes you to reach maximum medical improvement, because settling earlier risks leaving future care uncovered.
How long do I have to file a big rig accident claim in California?
Two years from the date of the crash for injury, and two years from the date of death for wrongful death. If a public entity was involved — a Caltrans road defect, a government vehicle — a Government Claims Act notice is generally due within six months. Evidence such as the truck's black box data and driver logs can be lost far sooner, so the practical deadline is weeks, not years.
Do I need a big rig accident lawyer near me in California?
You need one licensed in California who handles commercial truck cases — not necessarily one in your city. A Los Angeles firm can litigate a Bakersfield or Inland Empire crash; venue follows the crash location and the carrier, not the lawyer's office. Truck litigation is a practice specialty, not a neighborhood service. The referral network routes your request to a California-licensed truck attorney.
What is my truck accident case worth?
It depends on five things an attorney evaluates in the first consultation: the permanence and cost of your injuries, the strength of the liability evidence, how many defendants and insurance policies are involved, your state's comparative fault rule, and where the case can be filed. No honest source can value a case from a web page — but those five factors are why two similar crashes can settle for very different amounts.
Are truck accident settlements taxable?
Generally no. Compensation for physical injuries — medical costs, lost wages tied to the injury, pain and suffering — is excluded from federal income tax under IRS Publication 4345. Punitive damages and interest on a judgment are taxable, and emotional distress damages not tied to a physical injury can be. Confirm your situation with a tax professional.
Can you sue a truck driver personally?
Yes, and the driver is usually named as a defendant — but the driver is rarely the main source of recovery. The trucking company is liable for its employee's negligence and carries the policy that pays, so a claim is typically brought against the driver and the carrier together, plus any other company whose negligence contributed.
Where do I file a big rig accident lawsuit in California?
In the Superior Court of the county where the crash happened or where the carrier does business — Los Angeles, San Bernardino, Riverside, Kern, Sacramento, and Alameda counties see the most truck cases. Venue matters: it decides the jury pool and how fast the case reaches trial. If a public entity was involved, a Government Claims Act notice is generally required within six months, far sooner than the two-year statute.
Does anything happen when you file a complaint against a truck driver?
A safety complaint to the FMCSA's National Consumer Complaint Database can trigger an investigation and becomes part of the carrier's safety record, but it does not compensate you. Compensation comes from a civil claim, which runs on a separate track. Many people file both: the regulatory complaint documents the violation; the lawsuit recovers the damages.
