Semi-truck and 18-wheeler crashes cause some of the most devastating injuries on California roads.
These cases involve overlapping federal regulations, multiple liable parties, and evidence that disappears fast.
In Los Angeles County, more than half of all fatal commercial truck crashes in California occur in or near the city. You need attorneys who know FMCSA rules, black box data, and how to hold trucking companies accountable.
A semi-truck weighs up to 80,000 pounds. Your car weighs roughly 4,000. When those two meet at freeway speed, the outcome is almost never equal.
At El Dabe Ritter Trial Lawyers, we represent seriously injured crash victims throughout the Los Angeles metro area. These are not ordinary car accident cases. They involve federal trucking law, commercial insurance policies worth millions, and carrier defense teams that mobilize within hours of a crash.
Our Los Angeles truck accident lawyers mobilize just as fast.

Why Los Angeles Is a High-Risk Zone for Semi-Truck Crashes
Los Angeles sits at the center of the nation’s largest freight network. The Ports of Los Angeles and Long Beach together handle roughly 40 percent of all U.S. containerized imports, according to the Port of Long Beach. That freight moves almost entirely by truck.
The result: tens of thousands of heavy 18-wheeler vehicles operate on Los Angeles freeways every single day.
LA's Most Dangerous Freight Corridors
- I-710 (Long Beach Freeway) - Primary port-to-inland route; highest truck density in California
- I-405 / I-710 interchange (Lynwood) - High-speed merging between trucks and passenger vehicles
- I-5 through the Central LA corridor - Major north-south through-freight route
- I-110 (Harbor Freeway) - Port connector with narrow lanes and heavy truck mix
- US-101 and SR-60 - East-West distribution routes serving the Inland Empire
According to TIMS California crash data, half of all semi-truck accident fatalities in the state occur in Los Angeles County, despite the county holding only 27 percent of the state’s population. Older freeway designs, heavy construction zones, narrow shoulders, and port-driven delivery pressure all contribute.
How Semi-Truck Cases Are Different from Regular Car Accidents
Most personal injury cases involve two drivers, one insurer, and one set of facts. Semi-truck cases are categorically different.
Multiple Defendants and Insurers
A single 18-wheeler crash can involve the following parties:
- Truck driver
- Motor carrier
- Shipper
- Cargo loading company
- Leasing company
- Truck manufacturer
- Maintenance contractor.
Each may carry separate liability insurance. Identifying all responsible parties and all available insurance coverage is one of the first critical tasks your attorney must perform.
Federal Regulations Create Additional Liability
Commercial trucking is governed by the Federal Motor Carrier Safety Administration (FMCSA) under Title 49 of the Code of Federal Regulations. When a trucker or carrier violates those regulations and a crash results, those violations can establish negligence per se under California law. That means the violation itself is treated as proof of a duty breach, strengthening your case significantly.
Evidence Has a Short Life
Trucking companies dispatch inspectors and defense investigators to crash scenes within hours. Black box data from the truck’s Electronic Control Module (ECM) can be overwritten. Driver logs can be altered. Surveillance footage from nearby businesses gets deleted on rolling 30-day cycles.
Your attorney must send spoliation letters and issue preservation demands immediately. Every hour matters.
Key Federal Regulations That Drive Truck Accident Claims
Hours of Service Violations (49 CFR Part 395)
Federal hours-of-service (HOS) rules limit property-carrying commercial drivers to 11 hours of driving within a 14-hour on-duty window, following a mandatory 10 consecutive hours off duty. Drivers cannot drive after the 14th hour regardless of how many driving hours remain. A mandatory 30-minute break is required after 8 cumulative hours of driving.
When a carrier violates these rules or pressures drivers to drive while fatigued, it creates direct carrier liability. Per-load independent contractor pay structures, common among port drayage operators on the I-710, create a financial incentive to push those limits. FMCSA data shows fatigue is one of the leading causes of large-truck crashes nationwide.
In a Los Angeles semi-truck accident claim, an hours-of-service violation under 49 CFR Part 395 can establish negligence per se against the carrier, meaning the regulatory violation itself serves as evidence of a duty breach without requiring additional proof of unreasonable conduct. If the carrier knowingly permitted or scheduled trips that required HOS violations, the facts may also support a claim for punitive damages under California Civil Code Section 3294.
Electronic Logging Device (ELD) Data (49 CFR Part 395.26)
Since 2017, most interstate commercial carriers have been required to use Electronic Logging Devices. ELDs automatically capture driving time, on-duty periods, engine hours, vehicle movement, and GPS location. Unlike the paper logs drivers could falsify, ELD data creates an objective, timestamped record.
In litigation, ELD data is subpoenaed early and cross-referenced against dispatch records, fuel receipts, weigh station records, and toll data to reconstruct exactly what the driver was doing in the hours before a crash.
CDL Requirements and Driver Qualification (49 CFR Part 391)
A commercial driver operating a vehicle with a gross vehicle weight rating (GVWR) over 26,001 pounds, or any vehicle carrying hazardous materials, must hold a valid Commercial Driver’s License (CDL) with appropriate endorsements. Carriers have an affirmative duty to verify driver qualifications, conduct background checks, and review Motor Vehicle Records (MVRs) before hiring.
When a carrier puts an unqualified, medically disqualified, or suspended CDL driver behind the wheel, that negligent entrustment is a separate, powerful basis for liability.
FMCSA Inspection Records and Safety Ratings (49 CFR Part 385)
Every FMCSA-registered motor carrier has a publicly accessible Safety Measurement System (SMS) profile showing roadside inspection histories, out-of-service rates, and Compliance Safety Accountability (CSA) scores. A carrier with a history of brake violations, HOS infractions, or driver qualification failures and a pattern of crashes creates strong grounds for gross negligence claims.
We pull FMCSA carrier profiles on every case.
Cargo Securement Rules (49 CFR Part 393)
Federal regulations require cargo to be properly blocked, braced, and secured to prevent shifting during transport. Improperly loaded containers are common at the Port of Long Beach and Port of Los Angeles, where drayage truck turnarounds are fast and oversight is thin. A shifted load can cause sudden loss of vehicle control, rollovers, or dropped debris that triggers multi-vehicle collisions.
Underride Guard Requirements (FMVSS 223 and 224)
Rear underride crashes occur when a passenger vehicle slides beneath a semi-trailer after a rear impact. They are among the most lethal collision types because they bypass every standard vehicle safety system: airbags do not deploy effectively, crumple zones never engage, and the trailer edge contacts occupants directly at head level.
Federal Motor Vehicle Safety Standards 223 and 224 require rear underride guards on trailers with a GVWR over 10,000 pounds manufactured after January 1998. The U.S. Government Accountability Office has documented that damaged or noncompliant guards on the road are not subject to mandatory annual inspection under existing FMCSA regulations.
There are currently no federal requirements for side underride guards. Side underrides, which typically occur when a truck makes a wide turn across traffic, are equally lethal but largely unprotected by federal standards.
From 2008 through 2017, the U.S. DOT reported an annual average of approximately 219 fatalities in underride crashes involving large trucks, with researchers noting that actual numbers are likely higher due to inconsistent state reporting. (Source: U.S. GAO, GAO-19-264)
The Black Box: What the Semi-Truck's Data Recorder Reveals
Modern semi-trucks are rolling data centers. The truck’s Electronic Control Module (ECM), sometimes called the “black box,” records speed at impact, brake application timing, engine RPM, throttle position, and cruise control status. Some newer trucks also carry forward-facing cameras and telematics systems with real-time GPS and event data.
In a crash reconstruction, ECM data can prove that the driver never braked, was exceeding safe speeds, or was running with a throttle override. This data can make or break a case.
ECM data is not automatically preserved. It can be overwritten within days. A preservation demand, and in some cases a TRO requiring the carrier to preserve all vehicle data systems, must be issued immediately.
Types of Semi-Truck Crashes We Handle in Los Angeles
Not every 18-wheeler crash is the same. The crash dynamics, applicable regulations, and liable parties differ significantly by crash type.
Rear-End Collisions
A loaded semi traveling at 65 mph requires up to 525 feet to stop, roughly the length of 1.5 football fields. Rear-end crashes by trucks are frequently caused by following too closely, distracted driving, fatigued driving, or brake failure. These crashes are common on LA's congested freeways, particularly during I-405 and I-710 stop-and-go slowdowns.
Jackknife Crashes
A jackknife occurs when a semi's trailer swings outward at an angle relative to the cab, often due to sudden braking, brake failure, or poor road conditions. The trailer can sweep multiple lanes and crush vehicles alongside it.
Wide-Turn Crashes (Right-Turn Squeeze)
Trucks require wide arcing right turns. Drivers often swing left before turning right, sweeping the adjacent lane, shoulder, or bicycle lane. Cyclists and motorcyclists in the zone near the Port of Long Beach and Port of LA are particularly vulnerable to this maneuver. The truck driver has a duty to check mirrors and signal before executing a wide turn.
Underride Collisions
As detailed above, underride crashes are uniquely lethal. In Los Angeles, they occur most often on high-speed freeway on-ramps, during late-night operations with poor trailer visibility, and near port areas where trucks stop suddenly in traffic lanes.
Tire Blowouts and Debris Crashes
A commercial truck tire failure at speed can send rubber and steel shrapnel across multiple lanes. A sudden blowout can cause the truck driver to lose control. Maintenance records, tire age, inspection logs, and retreading history are all relevant evidence.
Rollover Crashes
Improperly loaded cargo, excessive speed on freeway ramps, or sudden swerving maneuvers can cause an 18-wheeler to roll over. In Los Angeles, high-speed curved interchange ramps, such as those at the I-405/I-710 junction, are particularly dangerous for top-heavy loads.
Who Is Liable After a Semi-Truck Crash in Los Angeles?
California law permits recovery from every party whose negligence contributed to the crash. In a commercial trucking case, that list is often longer than victims expect.
- Truck Driver - for negligent driving, HOS violations, impaired driving, distracted driving
- Motor Carrier - for negligent hiring, supervision, vehicle maintenance, and HOS pressure
- Cargo Shipper or Loader - for improper loading or securement of cargo
- Truck or Trailer Manufacturer - for mechanical defects (brake failures, tire defects, underride guard failures)
- Maintenance Company - for negligent repair or failure to identify known defects
- A Freight Broker - in certain cases involving negligent carrier selection
- Cargo Leasing Company - if they maintained control over the vehicle or driver
California follows pure comparative fault principles (California Civil Code Section 1714). If the crash was 100% the truck’s fault, you recover 100% of your damages. If another driver was also partially at fault, your recovery is reduced only by your own percentage of fault, if any.
What Compensation Can You Recover?
Semi-truck crash injuries are often catastrophic: traumatic brain injury, spinal cord injury, internal organ damage, crush injuries, amputations, and wrongful death.
Economic Damages
- Medical expenses: emergency care, hospitalization, surgery, rehabilitation, future care needs
- Lost wages and loss of future earning capacity
- Property damage and vehicle replacement
- In-home care and assistive devices
Non-Economic Damages
- Pain and suffering
- Emotional distress
- Loss of enjoyment of life
- Loss of consortium (for spouses and domestic partners)
Punitive Damages
California Civil Code Section 3294 permits punitive damages when the defendant’s conduct was fraudulent, oppressive, or malicious.
In trucking cases, punitive damages are most often pursued when a carrier had documented knowledge of an unsafe driver or vehicle and continued operating anyway, or when dispatch records show management directed HOS violations. These cases have produced some of the largest truck accident verdicts in California history.
Los Angeles Courts, Agencies, and Resources for Truck Crash Victims
Understanding the local landscape matters. It shapes where your case is filed, how evidence is gathered, and which local experts can support your claim.

What El Dabe Ritter Trial Lawyers Does in Semi-Truck Cases
We treat semi-truck cases as the complex federal and state litigation they are. Here is what that looks like in practice.
Immediate Evidence Preservation
Within hours of retaining us, we issue written spoliation demands to the carrier and driver requiring preservation of all ECM data, ELD records, driver qualification files, maintenance logs, dispatch records, and communications. If warranted, we seek a court order.
FMCSA Investigation
We pull the carrier’s full FMCSA Safety Measurement System profile, inspect CSA scores across all seven BASIC categories, review prior out-of-service orders, and obtain the driver’s complete qualification file through subpoena. Prior violations and known safety failures are central to punitive damage claims.
Independent Crash Reconstruction
We retain experienced accident reconstruction engineers and forensic analysts to independently analyze ECM data, roadway evidence, vehicle damage patterns, and post-crash inspections. Our experts testify at deposition and trial. [Link: Expert Witnesses page]
Full Liability Analysis
We trace the entire commercial relationship from the shipper who booked the load to the company that owned the trailer. Every contract, every insurance policy, and every party with potential liability is identified before we make a demand.
Trial-Ready Litigation
El Dabe Ritter Trial Lawyers prepares every case as if it will go to trial. Insurance companies know which firms go to trial and which firms settle for less. Our trial record is why carriers and their insurers take our demands seriously.
Other firms send a demand letter and wait. We build the case from the crash scene up. In semi-truck cases, the evidence that wins trials is the evidence you secure in the first 72 hours. We have never charged a fee unless we recover for our clients, and we do not start the clock by sending a demand letter. We start it the moment we take your call.
Semi-Truck Accident Frequently Asked Questions
How long do I have to file a semi-truck accident lawsuit in California?
California Code of Civil Procedure Section 335.1 gives personal injury victims two years from the date of injury to file a lawsuit. For wrongful death claims, the two-year period runs from the date of death. However, waiting even a few days can jeopardize your case. Critical black box data, surveillance footage, and driver log records can be lost permanently. Contact an attorney as soon as you are physically able.
What if the truck driver was an independent contractor?
Motor carriers frequently misclassify drivers as independent contractors to limit liability. California courts look at the actual relationship, not the contract label. Under the FMCSA’s truth-in-leasing regulations (49 CFR Part 376) and California’s employment classification standards, if the carrier controlled how, when, and where the driver worked, the carrier may still be vicariously liable for the driver’s negligence. This is a heavily litigated issue in California trucking cases.
What is a 'black box' and how does it help my case?
The Electronic Control Module (ECM) in commercial trucks continuously records speed, braking, throttle position, and engine data. In a crash, it preserves a data snapshot of the truck’s behavior in the seconds before impact. This data can prove the driver never applied brakes, was speeding, or had a mechanical fault. Your attorney must demand preservation of this data immediately after the crash, before it is overwritten.
Can I sue the trucking company even if the driver was at fault?
Yes. Motor carriers are vicariously liable for the negligent acts of their employed drivers under the respondeat superior doctrine. Beyond vicarious liability, the carrier itself may be directly liable for negligent hiring, negligent supervision, negligent vehicle maintenance, or pressuring drivers to violate hours-of-service rules. Direct carrier liability is often a stronger claim than driver liability alone.
What are FMCSA hours-of-service rules and why do they matter?
Under 49 CFR Part 395, commercial truck drivers may only drive 11 hours within a 14-hour on-duty window after 10 consecutive hours off duty. They must take a 30-minute break after 8 hours of driving. Weekly limits cap on-duty time at 60 or 70 hours depending on carrier schedule. When these rules are violated and a crash results, the violation can establish negligence per se under California law and potentially support a punitive damages claim.
What is an underride collision and why is it so deadly?
An underride crash occurs when a passenger vehicle slides beneath the chassis of a semi-trailer. Because the trailer sits high above the road, a car’s front crumple zones, airbags, and bumpers all pass underneath the trailer without engaging. The trailer edge strikes the passenger compartment directly at windshield and roof level. The results are almost always catastrophic. Federal law requires rear underride guards on most trailers, but side underride guards are not federally required, leaving millions of older trailers vulnerable.
How much is a semi-truck accident case worth?
No attorney can ethically promise you a specific number before reviewing the facts of your case. In general, commercial truck accident cases yield significantly higher settlements and verdicts than standard car accident cases because injuries are more severe, insurance coverage is much higher (federal minimum insurance for interstate carriers is $750,000 under 49 CFR Part 387, and many large carriers carry $5 million or more), and punitive damages are available in appropriate cases.
What if I was hit by a port drayage truck near the Port of Los Angeles or Port of Long Beach?
Port truck cases involve unique facts. Many port drayage drivers are classified as independent contractors paid per load, creating intense pressure to skip rest periods. Carrier liability, shipper liability, and cargo loader liability all become relevant. The Port of Los Angeles and Port of Long Beach operate their own gate camera systems that may have captured your crash. Our attorneys handle port-corridor truck cases regularly and know how to access that evidence.
Do I need a lawyer who specializes in semi-truck accidents, or can any personal injury attorney handle my case?
Semi-truck cases require working knowledge of FMCSA regulations, CDL requirements, commercial insurance structures, ELD and ECM data forensics, and multi-party litigation strategy. A general personal injury attorney unfamiliar with federal trucking law may miss critical violations, fail to identify all liable parties, or settle for far less than the case is worth. Choose a firm with documented experience in commercial vehicle litigation.
What happens if the trucking company's insurance company contacts me first?
Do not give a recorded statement to any insurance company, including your own, before speaking with an attorney. Carrier insurers deploy experienced claims adjusters immediately after major crashes. Their goal is to limit the company’s exposure. Anything you say can be used to reduce your claim. You have no legal obligation to speak with the carrier’s insurer before retaining counsel.
The Numbers Behind Large Truck Crash Danger
These statistics come from federal agencies and published research. We include them because understanding the scope of the problem is part of understanding what you are up against.
- 5,375 large trucks were involved in fatal crashes in the United States in 2023, representing an 8.4% decrease from 2022 but a 43% increase over the prior decade. (Source: NHTSA, FMCSA, 2023 Large Trucks crash data)
- In 2023, there were 83,179 injury crashes involving trucks and buses in the U.S., averaging over 9 injury crashes every hour. (Source: FMCSA Motor Carrier Management Information System, 2023)
- 436 people were killed in commercial truck crashes in California in 2022. More than 1,400 were injured in tractor-trailer accidents in Los Angeles County alone that year. (Source: National Safety Council; UC Berkeley TIMS)
- From 2008 through 2017, underride crashes involving large trucks killed an average of approximately 219 people annually in official government data. Researchers note the actual number is likely higher due to inconsistent state reporting. (Source: U.S. GAO, GAO-19-264, March 2019)
- The federal minimum liability insurance for most interstate carriers is $750,000 under 49 CFR Part 387. Many major carriers carry $5 million or more.
