Louisiana Truck Accident Lawyers

A commercial truck crash case involves multiple parties, a federal regulatory overlay, and corporate defendants with in-house legal teams. Morris & Dewett has handled commercial vehicle crash cases for 25 years.

Why Truck Accident Cases Are Legally Different from Car Accident Claims

A fully loaded tractor-trailer weighs up to 80,000 lbs under federal limits. The average passenger vehicle weighs about 4,000 lbs. That weight difference explains why collisions result in catastrophic injuries far more often than ordinary car crashes.

The physics create distinct hazards. Stopping distances for a loaded 18-wheeler at highway speed can exceed 500 feet. Blind spots extend up to 30 feet in front of the cab and 200 feet behind the trailer. Cargo shifts and tire blowouts can cause jackknife and rollover events that sweep across multiple lanes.

FMCSA

Federal Motor Carrier Safety Administration. The federal agency that regulates commercial vehicles, sets safety standards, and enforces trucking rules including hours of service, vehicle inspections, and driver qualifications.

The legal complexity goes beyond physics. Car accident cases involve one set of rules: state traffic law and general negligence principles. Truck cases involve a federal overlay. The FMCSA governs commercial trucking under 49 C.F.R. Parts 380-399. FMCSA regulations (49 C.F.R. Parts 380-399) create duties that do not exist in ordinary car accident law.

ECM

Engine Control Module. The truck’s onboard computer that records pre-impact speed, braking, throttle position, and other data. Sometimes called the “black box.” Data can be overwritten within 30 days without a preservation demand.

ELD

Electronic Logging Device. A device installed in commercial trucks that automatically records driving time. Required by federal law since 2019. ELD data is key evidence in truck accident cases because it documents hours behind the wheel.

Truck cases also involve evidence that car cases do not. The ECM records speed, braking, and throttle data. ELD logs document every hour behind the wheel. Driver qualification files contain medical certificates, driving records, and drug test history. None of that exists in a car accident case. And all of it has a short shelf life. ECM data can be overwritten within 30 days. Surveillance footage from nearby businesses is typically deleted within 24 to 72 hours.

How Federal Trucking Regulations Create Liability

HOS

Hours of Service. Federal rules limiting commercial drivers to 11 driving hours within a 14-hour on-duty window, with a mandatory 30-minute break after 8 hours.

HOS rules exist because fatigued driving kills people. Under FMCSA regulations, a commercial driver may drive no more than 11 hours after 10 consecutive hours off duty. The driver cannot extend that window past 14 hours from the moment they came on duty. Breaks are mandatory: 30 minutes after 8 cumulative hours of driving. Weekly limits cap driving at 60 hours over 7 days, or 70 hours over 8 days for carriers operating every day.

ELD devices became mandatory in 2017 and produce a digital record of every driving period. When a driver has exceeded hours-of-service limits, that record exists. Preserving ELD data before it is overwritten is a critical first step in any truck accident investigation.

CDL

Commercial Driver’s License. A federally required license for operating vehicles over 26,001 lbs GVWR, vehicles carrying hazardous materials, or vehicles transporting 16+ passengers.

Motor carrier duties extend well beyond HOS compliance. Carriers must screen drivers before hiring, which means pulling driving records, checking prior employers, and verifying CDL status and medical certification. They must train drivers specifically for the cargo they carry. Hazardous materials require endorsements and specialized training. Livestock and oversized loads have their own protocols. Carriers must also maintain vehicles to federal inspection standards and comply with cargo securement rules under 49 C.F.R. Part 393.

When a carrier violates any of these rules, that violation can establish negligence per se in Louisiana courts. The plaintiff does not need to prove the general standard of care was breached. The violation of the federal regulation is the breach. This is a meaningful legal distinction that affects how a case is built from day one.

A competent truck accident attorney requests the driver qualification file, HOS records, vehicle inspection logs (DVIRs), and the carrier’s FMCSA safety rating within days of engagement.

Who Can Be Held Liable in a Louisiana Truck Accident?

A Louisiana truck accident can involve up to six liable parties: the driver, the motor carrier, cargo loaders, the truck manufacturer, a maintenance company, and other motorists. Most people assume the driver is the only defendant. Each party requires a separate legal theory.

The driver is the most obvious starting point. Driver error contributes to crashes through speeding, fatigued driving, impairment from prescription or illicit substances, and performance errors on unfamiliar roads. The data is counterintuitive: about 80% of big rig wrecks involve the action or inaction of the motorist in the smaller vehicle, not the truck driver. But when truck driver error does contribute, fatigue and impairment are the most common causes.

respondeat superior

Latin for “let the master answer.” A legal doctrine holding employers liable for negligent acts committed by employees within the scope of their employment.

The motor carrier bears liability under two separate theories. respondeat superior makes the carrier directly liable for a driver’s negligence when the driver was acting within the scope of employment. The carrier is also liable for its own independent negligence: failing to screen drivers, cutting corners on training, skipping maintenance, or failing to enforce HOS rules.

One point that catches people off guard: the driver being classified as an “independent contractor” does not automatically insulate the carrier. Louisiana courts look at the actual degree of control the carrier exercised over the driver’s work. If the carrier set routes, controlled dispatch timing, and required the driver to follow company safety protocols, the contractor label may not hold up.

Cargo loaders and shippers carry their own liability when improper securement causes the crash. About 10,000 truck accidents occur annually in the U.S. from unstable or unsecured cargo. When a load shifts and causes a jackknife, the question of who loaded and secured that cargo becomes a primary investigation target.

negligent entrustment

A legal theory holding a vehicle owner or employer liable for knowingly allowing an unqualified, incompetent, or reckless person to operate a vehicle. Applies when the company knew or should have known about the driver’s unfitness.

Manufacturers and maintenance companies bear liability when equipment failure contributes. About 6% of fatal 18-wheeler crashes involve equipment failure, according to FMCSA data. Brake defects and tire blowouts are the most common. The Louisiana Products Liability Act (La. R.S. 9:2800.51) governs defective product claims against manufacturers. When a maintenance company failed to catch or repair a known defect, negligent entrustment and direct negligence theories both apply.

Louisiana’s Commercial Truck Accident Statistics

Large trucks and buses were involved in 97 fatal crashes in Louisiana during recent reporting years, representing 14% of all deadly crashes statewide, according to FMCSA crash records. Louisiana represents 1.4% of the U.S. population but accounts for 2.2% of all fatal truck crashes nationally.

Between 2,800 and 3,000 Louisianans are injured in commercial truck and bus crashes every year, accounting for 6% of all crash-related injuries statewide. The crash death rate is nearly double what the state’s population would predict.

The vehicle type breakdown matters. Seventy-two percent of truck crash fatalities are occupants of other vehicles, not truck drivers. When an 80,000-lb commercial vehicle strikes a 4,000-lb passenger car, the physics are one-sided. Fifty-eight percent of fatal truck crashes in Louisiana occur on rural roads, where emergency response times are longer and trauma centers are farther away. Seventy-three percent occur on non-interstate roads, where commercial trucks share lanes directly with local traffic.

Louisiana’s overall traffic fatality rate stands at 21 deaths per 100,000 residents, nearly double the national average of 12.9. Commercial vehicles contribute to that figure. Morris & Dewett’s truck and commercial-vehicle outcomes are on our case results page.

Preserving Evidence After a Louisiana Truck Accident

Preservation Letter

A formal legal demand sent to the trucking company requiring them to preserve all evidence related to the crash. Stops the carrier from overwriting black box data or destroying driver logs on their normal retention schedule.

The single most time-sensitive action in a truck accident case is locking down the evidence. A Preservation Letter sent to the carrier within 24 hours of engagement creates a legal obligation to preserve: ECM data, ELD logs, dashcam footage, maintenance records, driver qualification files, dispatch records, and insurance documents.

The clock matters because carriers and their insurers move fast. Within hours of a serious crash, the carrier’s legal team and insurance adjusters may be at the scene. Their job is to document the accident in a way that minimizes the carrier’s exposure. Witnesses are interviewed. Photographs are taken. The narrative begins forming before you have spoken to anyone.

At the scene, police reports document road conditions, skid marks, and debris patterns. Crash scene photographs capture the physical evidence. Witness statements establish what other drivers saw in the moments before impact. All of this becomes harder to gather as time passes.

Independent accident reconstruction is sometimes necessary when liability is disputed. Reconstructionists analyze vehicle positions, speeds, braking distances, and road conditions to establish how the crash happened and who caused it.

Medical records connect the crash to the injuries. Seeking care within 24 to 48 hours creates that documentation. Some injuries, including herniated discs and traumatic brain injuries, do not produce obvious immediate symptoms. A gap in medical care gives insurers an argument that the injuries were not caused by the crash.

Proving negligence requires tying each liable party to a specific regulatory violation or duty breach. FMCSA inspection reports, driver qualification files, and vehicle maintenance logs are primary discovery targets.

What Compensation Does Louisiana Law Allow After a Truck Accident

Louisiana law divides compensation into economic and non-economic categories. Economic damages cover losses with a measurable dollar value: medical bills, future medical care, physical therapy, rehabilitation, lost wages, and diminished earning capacity. When an injury ends or substantially reduces your ability to work, vocational experts and economists calculate the lifetime income loss and convert it to present value.

Loss of Consortium

A legal claim available to a spouse for the loss of companionship, affection, and support caused by the injured person’s condition. It is a separate damage category from the injured person’s own claims.

Non-economic damages cover what cannot be calculated on a spreadsheet: pain and suffering, mental anguish, physical impairment, and loss of enjoyment of life. A spouse may separately claim Loss of Consortium for the loss of companionship and support caused by the injuries.

When the crash kills someone, Louisiana law provides two separate claims. A wrongful death action under La. C.C. Art. 2315.2 allows surviving family members to recover their own damages: loss of financial support, loss of companionship, and funeral costs. A survival action under La. C.C. Art. 2315.1 recovers the victim’s own damages from the moment of injury to the moment of death. Both wrongful death and survival action claims can be filed together. More information on these claims is at our wrongful death page.

When the truck driver was intoxicated, La. C.C. Art. 2315.4 allows punitive damages in addition to compensatory damages. This is one of the few contexts where punitive damages are available in Louisiana civil cases.

Comparative Fault

A legal rule that reduces your recovery by your percentage of fault. In Louisiana, if you are 51% or more at fault, you recover nothing. If you are 50% or less at fault, your damages are reduced proportionally.

Louisiana uses a Comparative Fault system. La. C.C. Art. 2323 sets a 51% bar effective January 1, 2026. If you are 50% or less at fault, your damages are reduced by your fault percentage. If you are 51% or more at fault, you recover nothing. Insurance adjusters routinely push fault percentages up to reduce or eliminate recovery. Your attorney needs a specific strategy to counter this.

One Louisiana-specific rule catches people off guard. The “No Pay, No Play” law at La. R.S. 32:866 restricts recovery for uninsured drivers. If you were driving without insurance, you cannot recover the first $15,000 in bodily injury or the first $25,000 in property damage, even from a fully at-fault truck driver. This does not eliminate your claim, but it directly reduces what you can recover.

Prescriptive Period

Louisiana’s term for statute of limitations. The legal deadline to file a lawsuit. For personal injury, it is two years from the date of injury under La. C.C. Art. 3493.1 (effective July 1, 2024).

The Prescriptive Period for personal injury in Louisiana is two years from the date of injury under La. C.C. Art. 3493.1, effective July 1, 2024. If an attorney quotes you three years, they are working from a law that no longer exists. The two-year deadline is firm.

Steps to Take After a Truck Accident in Louisiana

Call 911 immediately after any crash involving injuries, blocked traffic, possible impairment, or a driver who fled the scene. Do not move the vehicles unless doing so is necessary for safety. Louisiana law requires a police report for any crash involving injury.

Seek medical evaluation within 24 to 48 hours, even if you declined treatment at the scene. A herniated disc or traumatic brain injury may not produce acute pain immediately. Insurance adjusters treat a gap in medical care as evidence that you were not seriously hurt. The medical record starts at the first evaluation.

Document the scene while you are there. Photographs of all vehicles, damage patterns, road conditions, weather, skid marks, and any visible injuries create a record that will not fade. Write down what happened while memory is fresh.

Collect the truck’s DOT number from the door of the cab. Get the driver’s name, license number, and insurance information. Get the carrier’s name and contact information. Obtain witness names and contact details. All of this is your right at the scene.

Do not give a recorded statement to the trucking company’s insurer. You are not required to, and early statements are often used to minimize claims. Notify your own insurer within 24 hours with a factual account of the crash. Do not discuss fault in detail.

Do not have your vehicle repaired until it has been inspected and documented by your attorney or a hired expert. The damage pattern is evidence.
