Truck Accident Lawyer
Critical truck-crash evidence may be in the trucking company's hands.
A collision with a fully loaded big rig is not a bad car accident on a larger scale — it is a different kind of case. A tractor-trailer can weigh twenty to thirty times what a passenger car does, and the injuries that result are often catastrophic: spinal-cord and brain injuries, multiple fractures, internal trauma, and worse. On top of the physical toll, a truck crash brings a commercial trucking company, its insurer, and often a defense team that begins working the case within hours — sometimes before you have left the hospital. Boyadzhyan Legal Shield represents people seriously injured by commercial trucks throughout Los Angeles, the San Fernando Valley, and San Bernardino County.
Founding attorney Knarik Boyadzhyan brings a trial lawyer's discipline to serious-injury claims — building liability on real evidence, documenting the full and future cost of an injury, and refusing to let an insurance company decide what a person's recovery is worth. Truck cases reward that discipline, because the evidence that wins them is technical and time-sensitive: federal driver logs, the truck's electronic control module, maintenance and inspection records, cargo-loading manifests. Much of it sits in the hands of the trucking company, and much of it can lawfully be overwritten or discarded on a routine schedule unless someone demands, in writing, that it be preserved.
There's also more money on the table, and more resistance to paying it. Commercial trucks are required to carry far larger liability policies than ordinary drivers, and multiple parties beyond the driver may share responsibility. That combination — bigger coverage, aggressive defense — is exactly why a truck case should be handled as its own kind of litigation from day one. No lawyer can promise a result, but we can promise a claim built on preserved evidence rather than on whatever the trucking company's adjuster is willing to concede.
What follows is general information about California law, not legal advice about your specific situation. An initial consultation is free, confidential, and carries no obligation to hire the firm.
The truck's black box and driver logs may be gone before anyone asks for them
A commercial truck records the story of the crash in data the trucking company controls: the engine control module (the 'black box'/ECM) capturing speed, braking, and throttle in the seconds before impact, and the electronic logging device (ELD) tracking the driver's hours behind the wheel. Under federal rules, some of these records only have to be retained for a limited time, and a repaired or scrapped truck takes its ECM with it. Trucking companies and their insurers know this, which is why they move quickly to control the scene. A lawyer can send a spoliation (evidence-preservation) letter demanding this data be kept before it's overwritten — and the sooner that letter goes out, the stronger your claim. Separately, California's deadline to file most truck-accident injury lawsuits is generally two years from the crash (Code of Civil Procedure § 335.1 (opens in new window)). Do not wait to get advice.
Truck Accident Cases We Handle
Jackknife accidents
When a trailer swings out of line with the cab — often from braking too hard, driving too fast for conditions, or equipment failure — the rig can sweep across multiple lanes and strike everything in its path. We work to show whether speed, brake maintenance, or driver error set the jackknife in motion.
Rear-end collisions by a big rig
A loaded truck needs far more distance to stop than a car, so a fatigued, distracted, or tailgating trucker who rear-ends you can cause devastating injury. Following too closely and driving too fast for conditions are Vehicle Code violations, and the ECM data often shows exactly when — and whether — the driver braked.
Underride accidents
In an underride, a smaller vehicle slides beneath the trailer, frequently causing catastrophic or fatal injury. These cases can involve missing or inadequate underride guards and questions of trailer visibility and lighting, in addition to how the collision occurred.
Tire blowout & road-debris crashes
A blown truck tire or a piece of shredded tread on the freeway can cause a driver to lose control or strike debris at speed. Blowouts frequently trace back to skipped maintenance, over-worn tires, or an overloaded truck — all of which point beyond the driver to the company and its maintenance provider.
Wide-turn & blind-spot accidents
Big rigs have large blind spots (the 'no-zones') and swing wide to make turns. A trucker who changes lanes into a car he can't see, or squeezes a right turn, can crush a vehicle beside him. Proving the truck's positioning and the driver's failure to check is central to these claims.
Overloaded & improperly loaded cargo
Cargo that's too heavy, unbalanced, or poorly secured changes how a truck brakes and handles and can spill or shift into a crash. When the load is the problem, the company or third party that loaded it — not just the driver — may be responsible.
Fatigued-driver crashes
Federal hours-of-service rules limit how long a trucker may drive before resting, and violating them causes drowsy-driving crashes. The driver's logs and ELD data can reveal a driver who was on the road far longer than the law allows.
DUI & drugged-driver crashes
A commercial driver impaired by alcohol, drugs, or even certain medications is held to a stricter standard than an ordinary motorist. Impairment can strengthen a civil claim and, in some circumstances, support a claim for punitive damages against the driver and company.
How We Prove Your Claim
Identifying every liable party
A truck crash rarely comes down to one person. The driver, the trucking company that employed him, the owner of the tractor or trailer, the company that loaded the cargo, a maintenance contractor, and even a parts manufacturer can each bear a share of the fault. Finding every responsible party — and every insurance policy behind them — often determines how much coverage is available, because a company carries far more coverage than an individual.
Preserving the black box, ELD & logs
The evidence that decides these cases is largely electronic and largely in the company's hands. We move quickly to send a preservation (spoliation) letter demanding the trucking company keep the ECM 'black box,' the electronic logging device data, driver logs, dispatch records, and maintenance files before any of it is overwritten or a damaged truck is scrapped. Locking down that data early is one of the most important things a lawyer does in a truck case.
Building the federal-violation record
Interstate trucking is governed by federal safety regulations (the FMCSA rules) covering driver hours of service, driver qualification and drug testing, and vehicle inspection and maintenance. A violation of those rules — an over-hours driver, a truck with known brake defects, a company that skipped required inspections — is powerful evidence of negligence, and we work to obtain the records that prove it.
Reconstructing the collision
When the company's version of events doesn't match the physical evidence, accident reconstruction connects the two. Using the ECM data, the scene, the vehicle damage, and the roadway, a qualified reconstructionist can establish speed, braking, positioning, and the sequence of a multi-vehicle crash — the objective account an insurer and a jury have to answer to.
Proving the full extent of your damages
Catastrophic injuries have costs that stretch across a lifetime, and insurers profit by treating them as temporary. We connect every injury to the crash through medical records and treating physicians, and document future surgeries, long-term care, permanent limitation, and lost earning capacity — the full arc of the injury — so the claim reflects what the harm will actually cost, not what the adjuster wants to admit.
What to do after a truck accident in Los Angeles
What you do after a truck crash matters even more than after an ordinary collision, because the other side moves fast. First, call 911 — with the severity of truck-crash injuries, you're entitled to have police and paramedics respond, and the officer's traffic collision report becomes an important early record. Do not leave the scene: leaving the scene of an injury accident is a crime, and even property-damage-only cases carry duties under Vehicle Code § 20002 (opens in new window). Get medical care right away, and keep getting it; a gap between the crash and treatment is the argument insurers use most often to claim you weren't really hurt.
If you're able, gather what you can before it disappears. Photograph the truck and your vehicle, the position of both, the roadway, and any debris or skid marks — and get the truck's company name, the number on the door or trailer, and the license and USDOT numbers if you can see them. Collect the names and numbers of any witnesses. This information helps a lawyer identify the company and act quickly, but never put your health at risk to gather it, and never assume the trucking company will preserve the evidence for you.
Two things to avoid. Do not admit fault or apologize at the scene — fault in a truck case depends on records you can't see yet, and an off-the-cuff apology can be twisted into an admission. And do not give a recorded statement to the trucking company's insurer, or accept a quick settlement, before speaking with a lawyer. A truck insurer's early settlement offer routinely arrives before the true extent of a catastrophic injury is known, and once you settle, the case is over. Report the crash to your own insurer as your policy requires, but get advice before you're recorded.
In a truck case, the driver is rarely the only one responsible.
Every California injury claim rests on negligence, and Civil Code § 1714 (opens in new window) sets the basic rule that everyone is responsible for injury caused to another by a want of ordinary care. Start with the driver, then keep going. Under the doctrine of respondeat superior, a trucking company is generally responsible for the negligence of a driver acting in the course of employment — and a company may be independently negligent for hiring an unqualified driver, pushing schedules that force drivers past their legal hours, or putting an unsafe truck on the road.
Liability can reach further still. The owner of the tractor or trailer, a separate company that loaded or secured the cargo, a maintenance contractor responsible for the brakes or tires, and a manufacturer of a defective part may each share fault depending on what caused the crash. A name on a truck door is a lead, not a defendant — each one still has to be tied to the conduct that caused this crash — and our guide to who can be liable for a truck accident in California works through how each role is tested. Why it matters to you is coverage: who is in the case determines how much insurance is actually available to pay for a catastrophic injury.
Federal safety regulations shape the whole analysis. The FMCSA rules governing interstate trucking limit a driver's hours of service, require driver qualification and drug and alcohol testing, and mandate regular vehicle inspection and maintenance — and they require companies to keep records proving compliance. A violation of those rules is strong evidence of negligence, which is precisely why the driver logs, ELD data, and maintenance files must be preserved before they can quietly disappear. Where fault is shared, California's comparative negligence rule reduces a recovery rather than barring it.
Damages for a catastrophic truck-crash injury
Because trucks are so much heavier, the injuries — and therefore the stakes — tend to be greater than in a typical car crash. What separates a truck case is that the losses are usually dominated by the future: years of treatment, surgeries, long-term or in-home care, and work a person can no longer do. Those future costs are proven with records, bills, and expert testimony projecting what care will cost over a lifetime, and our guide to what damages a California injury claim can cover sets out the categories.
In the most serious cases the non-economic harm — pain, disfigurement, and the loss of the ability to live as you did before — is the largest part of the claim. If the crash was fatal, surviving family members may bring their own claim for their own losses, which is covered on our wrongful death page.
Valuing a truck case well means valuing the whole future, not just today's bills — because once a claim is settled, there's no coming back if the injury proves worse than the trucking company wanted to admit. Where a driver or company acted with especially egregious conduct, such as driving drunk or knowingly running an unsafe truck, the law may in some circumstances allow punitive damages on top of compensatory ones.
The evidence can expire long before the deadline does.
For most truck-accident injury claims the statute of limitations is two years from the date of the crash under Code of Civil Procedure § 335.1 (opens in new window). In a truck case the practical clock runs faster still, because the electronic evidence that wins the case can be gone long before two years pass. The full set of California deadlines is in our guide to personal-injury filing deadlines.
A much shorter six-month deadline can apply when a government entity may be responsible — a city or county truck, a state vehicle, or a dangerous condition on a public road — and that's covered on our government liability page. It's not always obvious at the scene that a public entity is involved, which is a strong reason to get advice early rather than assume you have two full years.
Truck Accident Representation in Encino & the San Fernando Valley
Boyadzhyan Legal Shield is based in Encino on Ventura Boulevard and represents people injured by commercial trucks throughout the San Fernando Valley and greater Los Angeles — Encino, Sherman Oaks, Tarzana, Van Nuys, Woodland Hills, Studio City, Northridge, and the surrounding communities. The Valley sits at the crossroads of some of the busiest truck corridors in the region: the I-5, the US-101 (Ventura Freeway), and the I-405 all carry heavy commercial traffic, and the interchanges where they meet are where many of the worst truck crashes happen.
That local knowledge is practical, not decorative. Knowing how freight moves through a particular interchange, where the cameras are, and how a stretch of the 5 or the 405 tends to back up helps us reconstruct what happened and anticipate the arguments a trucking company's defense team will make. When a truck case cannot be resolved fairly and has to be filed, San Fernando Valley civil matters are generally heard at the Van Nuys Courthouse, and we appear in Van Nuys and the surrounding Los Angeles County courts.
Working from a single Encino office keeps the firm close to the clients and communities it serves. You work directly with the attorney handling your case — not a rotating cast at a high-volume settlement mill. The initial consultation is free, confidential, and carries no obligation to hire the firm.
