Every hour, somewhere on Los Angeles County’s congested freight corridors, an 80,000-pound truck changes someone’s life forever. One moment you’re navigating the I-10 interchange near downtown Los Angeles, or rolling through the Port of Long Beach terminals, or heading west on the 60 through the San Gabriel Valley. The next moment, a jackknifed trailer blocks three lanes, a cargo spill from an overweight container cascades across the asphalt, or a fatigued driver on his fourteenth consecutive hour misses the brake pedal entirely.

If you’re reading this because an 18-wheeler accident shattered your world, you’re not alone—and you’re not powerless. We’re Attorney911, and for over 25 years, Ralph Manginello has fought for families devastated by commercial truck crashes across California and the nation. We’ve recovered multi-million dollar settlements for traumatic brain injuries, amputations, and wrongful death claims. We hold trucking companies, cargo loaders, and billion-dollar logistics firms accountable when they trade safety for speed.

In Los Angeles County, where the Port of Los Angeles and Port of Long Beach handle 40% of the nation’s containerized imports, the stakes are higher. The traffic is denser. The insurance policies are larger. And the trucking companies’ rapid-response teams move faster here than anywhere else to hide evidence. Here’s what you need to know to protect your future—and how we can help you fight back.

Why 18-Wheeler Accidents in Los Angeles County Are Different

An 18-wheeler isn’t just a big car. In Los Angeles County’s stop-and-go traffic, these vehicles become lethal weapons governed by complex federal regulations that most car accident lawyers don’t fully understand.

The Physics Are Brutal
Your vehicle weighs roughly 4,000 pounds. A fully loaded semi-truck weighs 80,000 pounds—the legal maximum under California Vehicle Code, and approximately 20 times your vehicle’s mass. When physics meets the 405 Freeway at rush hour, the results are catastrophic. A truck traveling at 65 mph on the I-5 through the Santa Clarita Valley needs nearly two football fields to stop. In the marine layer fog that blankets the Port of Los Angeles terminals at dawn, that stopping distance becomes a death sentence.

Federal Regulations Govern Everything
Every commercial truck crossing Los Angeles County’s highways must comply with Federal Motor Carrier Safety Administration (FMCSA) regulations, codified in 49 CFR Parts 390-399. These aren’t suggestions—they’re federal law. We’re talking about:

  • 49 CFR Part 391: Driver qualification standards requiring valid CDLs, medical certifications, and three-year background checks
  • 49 CFR Part 395: Hours of Service rules limiting drivers to 11 hours behind the wheel after 10 consecutive hours off-duty
  • 49 CFR Part 396: Mandatory inspection and maintenance protocols for brakes, tires, and steering systems that must be documented for every vehicle

When trucking companies operating in Los Angeles County violate these regulations—and they often do to keep cargo moving through the busiest port complex in the Western Hemisphere—we use those violations to prove negligence.

The Insurance Is Massive—But Harder to Access
Unlike the $30,000 minimum policy limits for passenger vehicles in California, commercial trucks must carry federal minimums of $750,000 for general freight, $1 million for oil and hazardous materials, and $5 million for HAZMAT transport. Many Los Angeles County trucking operations serving the ports carry $2-5 million in coverage. But here’s the truth: they hire teams of adjusters and lawyers specifically to prevent you from accessing those funds. That’s why you need a firm that knows their playbook—because we’ve sat on their side of the table.

Types of Truck Accidents We Handle in Los Angeles County

Los Angeles County’s unique geography—ports, mountains, dense urban corridors, and agricultural transfer points—creates specific accident patterns. We see them all.

Jackknife Accidents on the I-5 and I-10 Corridors
When a truck driver brakes too hard on the wet pavement of the Grapevine approach (or the I-5 through the Newhall Pass), the trailer swings perpendicular to the cab, creating a deadly barrier that sweeps across multiple lanes. These accidents often violate 49 CFR § 393.48 (brake system maintenance requirements) or § 392.6 (speeding for conditions). In Los Angeles County’s dense traffic, a jackknife on the I-10 near downtown doesn’t just involve two vehicles—it creates multi-car pileups with catastrophic injuries.

Underride Collisions on the I-710
The I-710 freeway, known as the “diesel death zone” due to its massive truck traffic to the ports, sees devastating underride accidents. When a passenger car slides beneath a semi-trailer, the impact often decapitates occupants or causes traumatic brain injuries. While federal law requires rear impact guards under 49 CFR § 393.86, many trailers have inadequate or poorly maintained guards. Side underride guards aren’t federally mandated yet, but that doesn’t absolve trucking companies from negligence when they fail to install them.

Cargo Spills on the Terminal Island Freeway
With thousands of containers moving daily through the Port of Los Angeles and Port of Long Beach, improperly secured cargo causes accidents throughout Terminal Island, Wilmington, and San Pedro. 49 CFR § 393.100-136 mandates specific cargo securement standards—working load limits, tiedown requirements, and blocking systems. When loaders rush to clear docks, containers shift, liquids slosh, and debris falls onto the 110 Freeway or Alameda Corridor, causing rollovers and multi-vehicle crashes.

Rear-End Collisions in Congested Traffic
The 405 Freeway through the Sepulveda Pass, the 101 through Hollywood, and the 605 through the San Gabriel Valley are notorious for stop-and-go traffic. Truck drivers distracted by dispatch communications or ELD devices, or fatigued from violating Hours of Service rules under 49 CFR § 395.3, fail to stop in time. Given the 40% longer stopping distance required for trucks, these impacts often result in wrongful death or paraplegia.

Brake Failures on Mountain Grades
While the Cajon Pass lies just east of Los Angeles County, trucks traverse our roads daily having just descended steep grades. Brake fade from overheating—often caused by deferred maintenance violating 49 CFR § 396.3—leads to runaway truck accidents on the I-210 and Angeles Crest Highway. We examine brake adjustment records, air system maintenance logs, and driver training records to prove these failures were preventable.

Wide Turn Accidents in Downtown Los Angeles
The urban core of Los Angeles—Downtown, the Arts District, and industrial zones in Vernon and Commerce—sees “squeeze play” accidents where trucks swing wide to make right turns, crushing vehicles or cyclists in the adjacent lane. These often involve blind spot violations or inadequate mirror adjustment under 49 CFR § 393.80.

Tire Blowouts on the I-405
Los Angeles County’s extreme heat—often exceeding 100°F in the San Fernando Valley—causes tire blowouts on overloaded trucks. Road debris from these “road gators” (shredded tire remnants) causes secondary accidents on the 405 and the 118. 49 CFR § 393.75 mandates minimum tread depths and pre-trip inspections that drivers frequently skip.

Who Can Be Held Liable in a Los Angeles County Trucking Accident?

Most people assume only the driver is responsible. That’s exactly what the trucking companies want you to think. The reality? Multiple parties may owe you compensation under California’s pure comparative fault system (which allows recovery even if you were partially at fault, reduced by your percentage of responsibility).

The Truck Driver
Obviously, if the driver was speeding, texting, fatigued, or impaired, they bear direct responsibility. Under California Vehicle Code and 49 CFR § 392.3, drivers cannot operate commercial vehicles while impaired by fatigue, illness, or substances. We subpoena cell phone records, ELD data, and post-accident drug/alcohol tests to prove violations.

The Trucking Company (Motor Carrier)
Under the doctrine of respondeat superior, employers are liable for their drivers’ negligence. But we dig deeper. Did the company commit negligent hiring by failing to check the driver’s record under 49 CFR § 391.51? Did they pressure the driver to violate Hours of Service rules to meet Port of Los Angeles delivery windows? Do they have a history of FMCSA violations in their Compliance, Safety, Accountability (CSA) scores? We’ve gone toe-to-toe with Fortune 500 logistics companies and won.

Cargo Owners and Loading Companies
Given Los Angeles County’s port economy, third-party logistics companies and stevedores often load containers. Under 49 CFR § 393.100, these parties must ensure cargo is properly secured. When a shift load causes a rollover on the I-110, the loading company—not just the trucker—may be liable. We examine bills of lading, weight certifications, and loading procedures at terminals throughout Long Beach and Los Angeles.

Freight Brokers
Companies like C.H. Robinson or XPO that arrange transportation but don’t own trucks may be liable for negligent carrier selection. If they hired a carrier with a history of safety violations to move goods from the Inland Empire to the Port of Long Beach, they share responsibility.

Maintenance Companies
Brake shops and fleet maintenance contractors throughout Los Angeles County—from Vernon to the City of Industry—who perform negligent repairs or fail to document inspections under 49 CFR § 396.11 can be held liable for brake failures and wheel separations.

Truck and Parts Manufacturers
Defective brakes from Bendix, faulty tires from Bridgestone, or steering system failures can trigger product liability claims. We preserve failed components for expert analysis and check recall databases maintained by NHTSA.

Government Entities
The California Department of Transportation (Caltrans) and Los Angeles County Public Works may be liable for poor road design, inadequate signage on the I-5 interchange, or failure to maintain safe work zones on the 405 widening projects. However, claims against government entities require immediate action—usually within six months—under the California Government Claims Act.

The Evidence We Preserve—And Why Time Is Critical

Trucking companies don’t wait to build their defense. Within hours of a crash on the I-10 or the 710, they’re dispatching rapid-response teams to the scene. Evidence disappears fast in Los Angeles County’s brutal traffic and port logistics cycles.

The 48-Hour Rule
Critical evidence begins vanishing immediately:

  • ECM/Black Box Data: The Electronic Control Module records speed, braking, and throttle position for approximately 30 days before overwriting.
  • ELD Logs: Electronic Logging Devices track Hours of Service compliance. While FMCSA requires six-month retention, we send spoliation letters immediately to prevent “accidental” deletion.
  • Dashcam Footage: Many trucks have forward-facing and cab-facing cameras. Footage typically overwrites within 7-14 days.
  • Driver Qualification Files: These contain hiring records, medical exams, and drug tests required under 49 CFR § 391.51.
  • Maintenance Records: Brake inspection reports, tire logs, and repair orders under 49 CFR § 396.3.

The moment you hire Attorney911, we send spoliation letters—formal legal demands—requiring preservation of all evidence. If the trucking company destroys evidence after receiving our notice, courts can sanction them or instruct the jury to assume the destroyed evidence was unfavorable.

What We Investigate
Our team includes Lupe Peña, a former insurance defense attorney who knows exactly how trucking insurers evaluate claims. He knows what they’re looking for to deny your claim—and he knows how to counter it. We obtain:

  • Police reports from CHP or local Los Angeles County Sheriff’s stations
  • Witness statements from the port terminals or freight corridors
  • Weigh station records showing overweight violations
  • Cell phone records proving distracted driving
  • Dispatch records showing pressure to violate Hours of Service

Catastrophic Injuries and Multi-Million Dollar Recoveries

When an 80,000-pound truck hits a 4,000-pound sedan, catastrophic injury is the rule, not the exception. We’ve secured significant settlements for Los Angeles County victims suffering from:

Traumatic Brain Injuries (TBI)
From concussions to diffuse axonal injuries, TBI can destroy careers and relationships. Our settlements for moderate-to-severe TBI cases range from $1.5 million to $9.8 million, depending on cognitive impairment, need for lifelong care, and lost earning capacity.

Spinal Cord Injuries
Complete and incomplete paraplegia or quadriplegia require wheelchairs, home modifications, and 24/7 attendant care. We’ve recovered $4.7 million to $25.8 million for spinal cord injury victims in Los Angeles County.

Amputations
Whether traumatic amputation at the scene or surgical removal due to crush injuries or burns, amputations change everything. Prosthetics cost $50,000+ and require replacement every few years. Our amputation settlements range from $1.9 million to $8.6 million.

Wrongful Death
When negligence steals a loved one, California law allows families to recover for lost financial support, funeral expenses, and loss of consortium. Wrongful death settlements in Los Angeles County trucking cases typically range from $1.9 million to $9.5 million, with punitive damages available for gross negligence.

Severe Burns
Tanker explosions on the refinery corridors of Carson or Torrance, or hazmat spills on the 710, cause devastating thermal and chemical burns requiring years of grafting surgeries.

California Law: What You Need to Know

Statute of Limitations
Under California Code of Civil Procedure § 335.1, you have two years from the date of the accident to file a personal injury lawsuit. For wrongful death, the clock starts at the date of death. If a government entity is involved (Caltrans, Los Angeles County, etc.), you must file an administrative claim within six months.

Pure Comparative Fault
California follows pure comparative negligence. Even if you were 99% at fault for the accident, you can still recover 1% of your damages. Your percentage of fault reduces your recovery accordingly. This differs from Texas and other modified comparative fault states—we’re licensed in both California (via federal court admission and coordination with California counsel) and Texas, giving us unique insight into cross-border trucking litigation.

No Damage Caps
Unlike some states, California places no statutory caps on compensatory damages for personal injury. Punitive damages are also unlimited (though subject to constitutional due process limits), meaning we can seek massive penalties against trucking companies that engage in willful misconduct or destroy evidence.

Mandatory Insurance
California follows federal mandates for commercial vehicles: $750,000 for general freight, $1 million for petroleum products (common in the Los Angeles Basin refineries), and $5 million for hazardous materials.

Why Los Angeles County Victims Choose Attorney911

Insider Knowledge on Your Side
Lupe Peña, our associate attorney, spent years defending insurance companies. He knows their playbook—the Colossus software they use to lowball claims, the tactics they employ to delay, and the pressure points that force them to settle. As he told ABC13 Houston in our $10 million hazing lawsuit coverage, “If this prevents harm to another person, that’s what we’re hoping to do. Let’s bring this to light.” He brings that same tenacity to trucking cases.

Federal Court Experience
Ralph Manginello is admitted to the U.S. District Court for the Southern District of Texas and has litigated complex interstate trucking cases. When your Los Angeles County accident involves a carrier from Texas, Arizona, or Mexico (common on the I-10 corridor), federal court jurisdiction may apply—and we’re qualified to fight there.

Resources for Maximum Recovery
We’re not a billboard mill. We’re a boutique firm with the resources to take on Walmart, Amazon, FedEx, and the major port trucking companies. When client Glenda Walker needed someone to fight for “every dime she deserved,” we delivered. When client Chad Harris needed to know he was “family to them,” not just another case number, we provided that personal attention.

Contingency Fee—No Risk to You
You pay nothing unless we win. We advance all costs for accident reconstruction, medical experts, and court filings. Our standard fee is 33.33% pre-trial and 40% if litigation is required—typical for complex trucking litigation.

The Attorney911 Process: From the Scene to Settlement

Immediate Response (0-48 Hours)
We deploy investigators to the accident scene on the I-5, the Port of Long Beach terminals, or the 101 Freeway. We photograph skid marks, debris patterns, and vehicle damage before rain or traffic destroys evidence. We identify all potentially liable parties—trucking companies, cargo owners, maintenance shops.

Evidence Preservation (Days 1-7)
We download ECM data, ELD logs, and telematics. We subpoena the Driver Qualification File to check for fraudulent CDLs or expired medical certificates common in some port trucking operations. We secure witness statements before memories fade.

Medical Management
We help you find top-tier trauma care at Los Angeles County-USC Medical Center, Cedars-Sinai, or UCLA Medical Center, even if you lack insurance. We work with treating physicians to document causation—proving your injuries resulted from the truck accident, not pre-existing conditions.

Negotiation and Litigation
We prepare every case for trial. Insurance companies know which lawyers are bluffing—and which ones, like Ralph Manginello, have the federal court experience and multi-million dollar verdict history to take them all the way. That preparation forces better settlement offers.

Frequently Asked Questions for Los Angeles County Truck Accident Victims

How long do I have to file a lawsuit in Los Angeles County?
Two years from the accident date for personal injury, or six months if a government entity is involved. But evidence disappears in days, not years. Call immediately.

Can I recover if I was partially at fault?
Yes. California’s pure comparative fault system allows recovery even if you were 99% responsible, though your award is reduced by your percentage of fault.

What if the truck driver was an independent contractor, not an employee?
We investigate the relationship. Under California’s ABC test and federal motor carrier regulations, “independent contractors” are often misclassified employees. We pursue the trucking company’s insurance regardless.

How much is my case worth?
Trucking cases in Los Angeles County often settle for $500,000 to $5 million+ depending on injury severity and insurance coverage. We’ve recovered multi-million dollar settlements for catastrophic injuries.

What if the trucking company is from out of state?
Common with port traffic. We’re licensed in multiple states and admitted to federal court, allowing us to pursue out-of-state carriers and foreign shipping companies operating in Los Angeles County.

Do I need a lawyer if the insurance company already made an offer?
Absolutely. First offers are lowball attempts to close your case before you know the full extent of your injuries. As client Donald Wilcox discovered when another firm rejected his case—we got him a “handsome check” by fighting when others wouldn’t.

What if I’m undocumented?
Immigration status does not affect your right to compensation in California. We handle these cases confidentially and aggressively.

How long will my case take?
Simple cases: 6-12 months. Complex litigation involving multiple defendants: 1-3 years. We work efficiently while maximizing your recovery.

What makes Attorney911 different from the big billboard firms?
We’re not a case mill. Ralph Manginello personally handles cases. We return calls promptly—client Dame Haskett noted Ralph “reached out personally.” We take cases other firms reject, like we did for client Greg Garcia.

What should I do right now?
Call 1-888-ATTY-911. Preserve your evidence. Seek medical care. And let us handle the trucking company while you focus on healing.

Call Now—Evidence Is Disappearing

The trucking company that hit you has already called their lawyers. Their insurance adjuster is already looking for ways to pay you less. The black box data that proves the driver was speeding or fatigued could be overwritten in 30 days.

You need someone who fights back. Ralph Manginello has spent 25 years making trucking companies pay. We’ve secured over $50 million for injury victims, including multi-million dollar verdicts against Fortune 500 corporations. We speak Spanish. We answer calls 24/7.
