When an 80,000-pound commercial truck hits a passenger vehicle on the 710, the 5, or any Los Angeles freeway, the outcome is rarely minor. The physics are unforgiving. Victims are left with traumatic brain injuries, spinal cord damage, or losses their families will spend years trying to recover from, financially and emotionally.
California truck accident laws are not a single rulebook. Federal regulations set the baseline for how every commercial carrier must operate, and California layers its own rules on top, from state hours-of-service limits for local drivers to a state inspection program most attorneys never think to check. Knowing where federal law ends and California law begins often decides whether a violation gets found at all.
Here is what most people do not know: the battle begins in the hours immediately after the crash. Large trucking companies and their insurers deploy Rapid Response Teams, which are investigators, adjusters, and defense attorneys whose only job is to arrive at the scene quickly, secure the evidence on their terms, and build a defense designed to minimize what they pay you.
Haffner Law knows exactly how that playbook works, because we have been on the other side of it. We move fast to preserve critical evidence before it disappears. We know which federal and California regulations were violated. We are not intimidated by billion-dollar logistics corporations or the insurance carriers standing behind them.
If you were seriously injured in a truck crash in Los Angeles, you need representation that matches the resources being deployed against you.
How California and Federal Law Govern Truck Accidents
Commercial trucking sits at the intersection of two legal systems. Federal regulations, administered by the Federal Motor Carrier Safety Administration, set safety standards for any truck crossing state lines. California layers its own rules on top, and the difference between the two systems can become the central issue in your case.
Hours of Service: Federal vs. California Rules. A driver operating in interstate commerce must follow the federal Hours of Service rules, generally an 11-hour driving limit within a 14-hour on-duty window.[1] But a driver who works only within California, never crossing state lines, follows California’s own hours-of-service regulation instead. Under Title 13 of the California Code of Regulations, an intrastate truck driver may drive up to 12 cumulative hours following ten consecutive hours off duty, and may not drive after the 16th hour on duty.[8] The two frameworks overlap in places and diverge in others, and carriers sometimes blur the line between interstate and intrastate operations to their advantage. Our attorneys determine which set of rules actually applied to the driver who hit you, then use any violation, state or federal, as evidence of negligence.
CHP Terminal and Vehicle Inspections. Beyond hours of service, California enforces its own commercial vehicle safety program independent of federal oversight. Under the California Highway Patrol’s Basic Inspection of Terminals program, most commercial trucks over 10,000 pounds must be inspected roughly every 90 days, and the carrier’s terminal itself is subject to CHP audit of maintenance and driver records.[9] A carrier with a history of unsatisfactory BIT ratings, or one that cannot produce the maintenance records the program requires, has already told you something important about how it operates. We request these records early in every case.
Why Truck Accident Cases Are Fundamentally Different
Most people assume a truck accident is just a larger version of a car accident. It is not. While our firm handles the full spectrum of California vehicle accidents, commercial truck crashes involve unique layers of complexity that standard passenger vehicle claims do not.
The legal complexity, the volume of critical evidence, the number of potentially liable parties, and the scale of the commercial insurance policies involved all set these cases apart from any other motor vehicle claim. The most urgent difference: powerful digital evidence exists in commercial truck crashes that does not exist in other accident types, and that evidence can disappear permanently within days if action is not taken immediately.
Electronic Control Modules (Black Boxes): Modern commercial trucks record speed, braking force, throttle position, and hours of continuous driving in a device called an ECM or Event Data Recorder. This data proves a driver was speeding, failed to brake appropriately, or had been driving far beyond legal limits. The trucking company owns this data and can legally overwrite it after as little as 30 days unless a formal Spoliation Letter demanding its preservation is sent immediately. Haffner Law sends that letter as one of its first actions in every truck accident case.
Electronic Logging Device (ELD) Records: Federal law requires commercial drivers to log their hours of service electronically.[1] When a driver violates FMCSA Hours of Service regulations, pushing through fatigue to meet delivery quotas, that violation is recorded and recoverable. We subpoena those logs and use them to prove the driver was operating illegally and dangerously at the time of your crash.
Dashcam and GPS Telematics Data: Many commercial fleets use forward-facing cameras and GPS tracking systems. This footage can confirm precisely what the driver did in the seconds before impact. It must be preserved before the carrier’s own systems overwrite it.
Liability in Truck Accidents Extends Far Beyond the Driver
In a standard collision, liability typically rests with the driver who caused the crash. In a commercial truck accident, responsibility is almost never that straightforward.
Our attorneys examine every layer of the logistics chain to identify every party whose negligence played a role in your injuries. The trucking company itself can be held liable for negligent hiring, inadequate driver training, pressuring drivers to violate federal hours-of-service rules, and failing to maintain their vehicles properly. The driver may bear direct liability for speeding, distracted driving, impaired driving, or knowingly falsifying logbooks.
Third-party cargo loaders who improperly distribute weight or fail to secure cargo can cause a truck to become dangerously unstable, leading to jackknife accidents or rollovers that were entirely preventable. Vehicle and parts manufacturers face product liability claims when brake failure, defective tires, or faulty steering components contributed to the crash. Maintenance contractors who missed a critical defect during inspections or repairs may also share responsibility.
Government entities are a less obvious but real source of liability. Poorly designed intersections, missing signage, or unrepaired road defects that contributed to the collision may support claims against the city, county, or state agency responsible for that roadway.
Identifying every liable party is not just about accountability. It is about recovery. Each additional defendant means access to additional insurance policies, which directly affects the total compensation available to you.
Federal Motor Carrier Safety Administration (FMCSA) Violations
Commercial trucking in the United States is governed by a detailed body of federal law administered by the FMCSA. These regulations exist because commercial truck accidents are so consistently catastrophic. Violations of FMCSA rules are among the most powerful pieces of evidence of negligence available in these cases, because they show not just that something went wrong, but that the carrier had a legal obligation and chose not to meet it.
Key regulations we audit in every case include:
- Hours of Service (HOS) Rules: Federal law caps how many consecutive hours a commercial driver may operate without mandatory rest. A driver who exceeded those limits was operating illegally, and the ELD records prove it.[1]
- Pre-Trip Inspection Requirements: Drivers are federally required to inspect their vehicles before each trip and document that inspection. Failure to do so is a direct FMCSA violation.
- Drug and Alcohol Testing Programs: FMCSA mandates random testing for all commercial drivers. A carrier who kept a driver on the road after a failed test, or who failed to administer required testing, faces serious liability.
- Weight and Load Limits: Federal regulations set maximum weight limits and require cargo to be properly secured. Overloaded or improperly secured cargo dramatically increases accident risk.
- Vehicle Maintenance Standards: Carriers must maintain detailed maintenance records and conduct regular safety inspections. Allowing a vehicle with known defects to remain in service is a direct regulatory violation.
Once our attorneys establish an FMCSA violation, the case changes fundamentally. It stops being a question of whether a driver made a mistake. It becomes a question of why the carrier allowed that driver to be on the road.
Types of Truck Accident Cases in California
Los Angeles is one of the busiest freight distribution hubs in the United States. The ports of Los Angeles and Long Beach feed thousands of commercial trucks daily onto the I-710, I-5, I-10, and SR-60. We handle the full spectrum of commercial vehicle crashes across the region.
- 18-Wheeler and Semi-Truck Collisions: Highway crashes involving big rigs almost always involve layered insurance structures, with separate policies for the cab, the trailer, and the cargo. We identify every available policy to maximize your recovery.
- Jackknife Accidents: Hard braking on a slick surface or at high speed can cause the trailer to swing out perpendicular to the cab, sweeping across multiple lanes and involving several vehicles.
- Underride and Override Crashes: Some of the deadliest truck accident configurations occur when a passenger vehicle slides underneath a trailer or a truck rides over a smaller vehicle. Missing or defective rear underride guards are a frequent, preventable cause.
- Rollover Accidents: Caused by excessive speed on curves, improperly loaded cargo, or evasive maneuvers, rollovers can crush adjacent vehicles and spill hazardous materials across crowded freeways.
- Fatigued Driving Crashes: Driver fatigue is one of the leading causes of commercial truck accidents. When a driver falls asleep or experiences microsleep events, ECM and ELD data can prove it, if preserved in time.
- Delivery Truck and Last-Mile Accidents: Crashes involving Amazon delivery vans, FedEx, UPS, and other last-mile carriers in residential neighborhoods and commercial districts are a rapidly growing category of commercial vehicle litigation. These drivers operate under intense time pressure and quota systems, and the legal relationship between the driver and the company is frequently disputed, a challenge Haffner Law knows how to resolve in your favor.
- Hazardous Materials Accidents: Trucks transporting hazardous cargo are subject to additional federal regulations. When a spill causes injury, illness, or property damage, multiple layers of federal and state liability may apply.
Each of these case types carries its own evidentiary requirements, regulatory framework, and liability theory. Our attorneys tailor the investigation to the specific type of crash and the specific negligence at issue.
Serious Injuries That Demand Full Compensation
The size and weight disparity between commercial trucks and passenger vehicles is extreme. Occupants of smaller vehicles rarely escape without significant physical harm.
- Traumatic Brain Injuries (TBI): Ranging from concussions to severe cognitive impairment requiring lifelong care, rehabilitation, and in-home assistance.
- Spinal Cord Injuries and Paralysis: The crushing force of a truck impact can cause paraplegia, quadriplegia, or permanent nerve damage. These injuries affect every aspect of a person’s life and often require ongoing medical support for decades.
- Multiple Fractures: Broken bones throughout the body are common, frequently requiring multiple surgeries, hardware implantation, and extended physical therapy.
- Internal Organ Damage: Blunt trauma from a high-impact collision frequently causes internal injuries that are not immediately apparent but become life-threatening without prompt diagnosis.
- Severe Burn Injuries: If a truck’s fuel tank ruptures or cargo ignites, burns can be permanent and catastrophic.
- Wrongful Death: Truck accidents carry one of the highest fatality rates of any vehicle collision type in California. When a family loses a loved one, we help them pursue full compensation for lost future income, loss of companionship and consortium, funeral and burial expenses, and the profound value of the life taken. Wrongful death cases are handled with the same evidentiary rigor and the same commitment to maximum recovery.
The compensation you pursue must account not just for your current medical bills but for the full arc of your future, including ongoing treatment, lost earning capacity over years or decades, the impact on your family and your relationships, and the pain you carry every day. Our attorneys work with medical experts, life care planners, and forensic economists to build a damages case that captures all of it.
Why These Cases Have to Be Fought Hard
Holding trucking companies accountable serves a purpose well beyond a single settlement. These are often large logistics corporations that make calculated decisions about safety investments.
The math is simple: when the cost of cutting corners is low enough, too many of them choose to cut them. Successful litigation changes that calculation. When a carrier faces a multi-million-dollar verdict for pressuring drivers to violate hours-of-service rules, or for keeping a truck with failed brakes on the road, the financial consequences of those choices become very real.
California law permits punitive damages in cases where clear and convincing evidence shows conscious disregard for the safety of others.[6] That possibility does not exist in every case, but in cases where the facts support it, it forces carriers to take safety seriously in a way that regulatory compliance alone often does not.
Every truck accident case that is litigated to its fullest contributes to making Los Angeles roads safer for everyone on them.
Statute of Limitations: Time Is Not on Your Side
California law imposes strict deadlines for filing a truck accident lawsuit. Missing them permanently eliminates your right to compensation, regardless of how clear the carrier’s liability may be.
Standard Personal Injury Claims: Under California Code of Civil Procedure Section 335.1, you generally have two years from the date of the accident to file a lawsuit.[2]
Wrongful Death Claims: Families who lose a loved one in a truck accident have two years from the date of death to file a wrongful death lawsuit, also under Code of Civil Procedure Section 335.1.[2]
Claims Against California State or Local Government Entities: If the truck was operated by a California public entity, such as a Metro bus, a Caltrans vehicle, or a municipal sanitation truck, you must file an administrative claim under the California Government Claims Act within six months of the accident.[3] The procedural requirements are strict and the consequences of missing the deadline are permanent.
Claims Against Federal Government Entities: A USPS mail truck is a different animal entirely. Because the Postal Service is a federal agency, a crash with a USPS vehicle falls under the Federal Tort Claims Act, not California’s Government Claims Act. You must file an administrative claim, known as an SF-95, directly with the USPS within two years of the accident, then wait for a denial or six months of silence before you can sue in federal court.[4] Filing the wrong form with the wrong agency can cost you months you do not have.
Evidence Preservation, The More Urgent Deadline: The legal filing deadline and the evidence preservation window are two separate clocks running simultaneously. Black box data, dashcam footage, and ELD records can be overwritten within 30 to 90 days. A Spoliation Letter must be sent within 24 to 72 hours of retaining an attorney. This is why contacting a truck accident lawyer immediately after an accident is not just advisable. It is essential.
Why You Need a Truck Accident Lawyer From Day One
Commercial trucking companies have dedicated legal teams, long-standing relationships with specialized defense firms, and insurers whose entire business model depends on paying as little as possible. The moment a serious accident occurs, that entire machine is mobilized.
Going up against that system without legal representation means negotiating with claims adjusters who handle commercial truck cases every day, while you are dealing with an injury, a hospital stay, a family in crisis, and income that has suddenly stopped.
Our attorneys know how to obtain and interpret ECM data, ELD records, and maintenance logs. We know how to depose corporate safety officers and claims adjusters. We know which FMCSA violations create the strongest negligence arguments, which defenses carriers raise most frequently, and how to dismantle them with the evidence we have already locked down.
California follows a pure comparative negligence rule. Your compensation is reduced by the percentage of fault attributed to you, but you can still recover even if you played some role in what happened. Trucking companies and their insurers routinely attempt to inflate your share of fault to reduce their exposure. Our job is to prevent that from succeeding and to make certain the full extent of the carrier’s negligence is established on the record.
Haffner Law handles truck accident cases on a contingency fee basis. You pay nothing upfront and nothing unless we recover compensation for you. Our fee is a percentage of that recovery. There is no financial risk in calling for a consultation.
Frequently Asked Questions
Who can be held liable in a Los Angeles truck accident?
More than just the driver. Liable parties may include the trucking company, the cargo loading company, the truck or parts manufacturer, a maintenance contractor, or a government agency responsible for road conditions. We investigate thoroughly to identify every responsible party, which can mean access to more insurance coverage and a larger recovery for you.
What should I do immediately after a truck accident in Los Angeles?
Get medical attention right away, even if you feel fine. Some injuries show up later. If you can, photograph the scene, vehicles, cargo, and debris. Collect the driver’s name, CDL number, carrier name, and DOT number. Do not give a recorded statement to the trucking company’s insurer before talking to an attorney. Call a truck accident attorney as soon as possible so key electronic evidence can be preserved before it is deleted.
What is a Spoliation Letter and why is it so urgent?
A Spoliation Letter is a formal notice requiring the other party to preserve all accident-related evidence, such as black box data, driver logs, dashcam footage, GPS records, and maintenance reports. Trucking companies can legally delete this data within 30 to 90 days unless they receive this letter. Once they do, destroying evidence can be penalized heavily by courts. Haffner Law sends this letter at the very start of every truck accident case.
Can I sue if the truck driver was classified as an independent contractor?
Yes. Trucking companies often use independent contractor labels to avoid liability, but both federal and California law can hold carriers responsible regardless. Federal safety regulations frequently treat carriers as the legal employer, and California’s AB5 law makes it harder for companies to validly classify drivers as contractors.[5] We know how to challenge these arguments and hold the carrier accountable.
What is a typical truck accident settlement worth?
Truck accident settlements are often substantial because commercial policies are much larger than personal auto policies. Federal law requires a minimum of $750,000 for general freight carriers, and hazardous materials carriers must carry as much as $5 million.[7] Settlements typically need to cover medical costs, long-term rehabilitation, lost income, and pain and suffering. The value of your case depends on your injuries, the evidence, and who is liable. We never recommend accepting a settlement before completing a full case evaluation.
What if I was partially at fault for the truck accident?
You can still recover compensation. California’s pure comparative negligence rule reduces your payout by your percentage of fault, but does not eliminate it. For example, if you are 15% at fault on a $1,000,000 claim, you would still recover $850,000. Trucking companies often try to exaggerate your share of fault. Our attorneys counter that with evidence and witness testimony gathered during our investigation.
How long do I have to file a truck accident lawsuit in California?
Generally, you have two years from the date of the accident. If a California state or local government agency operated the truck, you must file an administrative claim within just six months. If the truck was a federal vehicle, such as a USPS mail truck, a different federal process applies, with its own two-year administrative filing deadline. Contact an attorney immediately. Preserving evidence is even more time-sensitive than the filing deadline itself.
