Truck accidents are not car accidents. The vehicles are larger, the injuries are more severe, and the legal process is more complex. Morris & Dewett has handled big truck injury cases across Louisiana for 25 years.
Immediate Steps at the Truck Accident Scene
Your safety comes first. Move to the shoulder or median if you can do so without risking further injury. Turn on your hazard lights. Do not stand in traffic lanes or near the truck.
Call 911 immediately. Louisiana law requires reporting any accident involving injury or significant property damage. Emergency responders assess the scene, treat injuries, and prepare an official police report. That report becomes a foundational document in your claim.
Do not move anyone who is seriously injured unless there is immediate danger. Fire, chemical spills from hazmat cargo, or fuel leaks are exceptions. Otherwise, wait for paramedics.
DOT number
U.S. Department of Transportation number. A unique identifier assigned to commercial carriers operating in interstate commerce. Displayed on the cab door and used to look up the carrier’s safety record, insurance, and inspection history in federal databases.
If you are physically able, start documenting. Photograph vehicle damage from multiple angles. Capture the truck’s DOT number and MC number on the cab door or trailer. These numbers identify the carrier in FMCSA databases. Photograph road conditions, traffic signals, skid marks, and the debris field. Video the scene if possible. Video captures spatial relationships that individual photos miss.
Louisiana recorded 3,559 large truck crash involvements in FY 2025, resulting in 82 fatalities and 1,745 injuries according to FMCSA crash data.
Why Truck Accidents Are Different from Car Accidents
A car accident typically involves two drivers and two insurance companies. A truck accident can involve six or more potentially liable parties. The driver, the trucking company, the freight broker, the cargo loading company, the maintenance provider, and the truck or parts manufacturer may all share responsibility.
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.
Federal regulations from the FMCSA govern commercial trucking. These include HOS limits, vehicle inspection requirements, and driver qualification standards. A car accident claim rarely involves federal regulations. A truck accident claim almost always does.
Trucking companies carry substantially more insurance than individual drivers. FMCSA requires a minimum of $750,000 in liability coverage for general freight carriers. Hazmat carriers must carry at least $1 million. Large passenger carriers must carry $5 million. These higher policy limits mean more money is at stake, and the insurance defense is more aggressive.
The trucking company’s legal team moves fast. Many carriers have rapid-response investigators who arrive at the scene within hours. They photograph the scene, take statements, and begin building a defense before you have spoken to an attorney. This is not an exaggeration. It is standard industry practice.
Common trucking violations that cause accidents include HOS violations, inadequate vehicle maintenance, unqualified drivers, improper cargo loading, and falsified logbooks.
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.
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.
The evidence in truck cases is electronic and volatile. ELD data, ECM records, GPS tracking, dash cam footage, and dispatch records can all disappear if not preserved quickly.
What Evidence Disappears Fast After a Truck Crash?
Truck accident evidence has a shelf life measured in days, not months. ELD data, ECM records, dash cam footage, and dispatch logs can all be overwritten or destroyed on routine schedules without a preservation demand.
ELD data records the driver’s hours behind the wheel. Federal law requires these devices in commercial trucks. The data can be overwritten on the truck’s normal operating cycle. If no one sends a preservation demand, the carrier has no obligation to keep it beyond their standard retention period.
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.
ECM data is the truck’s “black box.” It records pre-impact speed, braking patterns, throttle position, and engine diagnostics. This data can be overwritten within 30 days without a Preservation Letter on file.
Dash cam footage runs on loop recording systems. Older footage is overwritten as new footage records. Without a preservation demand, critical video may be gone within weeks.
Trucking company dispatch records and driver communications document what the company knew and when. These records may be destroyed on a routine retention schedule. GPS and telematics data showing the truck’s route, speed history, and stop patterns are equally time-sensitive.
Driver qualification files contain training records, violation history, drug and alcohol test results, and medical certifications. These files reveal whether the company knew the driver was unfit. If the company destroys these records after litigation is foreseeable, Louisiana courts can impose an adverse inference. That means the jury can assume the destroyed evidence was unfavorable to the trucking company.
Spoliation
The destruction or alteration of evidence after a party has notice of pending litigation. Courts can instruct juries to assume the destroyed evidence was unfavorable to the party that destroyed it.
This is why a Spoliation letter must go out immediately. Morris & Dewett sends preservation letters within 24 hours of engagement. The black box data, driver logs, and maintenance records get locked down before anyone can delete them. Learn more about the truck accident investigation process.
What to Collect at the Scene: The Truck-Specific Checklist
Car accident checklists tell you to exchange insurance information. Truck accidents require more. The truck-specific information you collect at the scene can determine whether critical evidence is preserved or lost.
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.
Get the driver’s name, CDL number, and employer name. The driver and the trucking company may be different entities with separate insurance policies.
Record the truck’s DOT number and MC number from the cab door. Write down the trailer number. The trailer is often owned by a different company than the tractor. This matters because it identifies additional potentially liable parties.
Get insurance information from the driver. Record the names and badge numbers of every responding officer. Collect names and contact information from any witnesses. Witness statements from other motorists, pedestrians, or nearby business employees can corroborate your account.
Photograph the truck’s condition. Look at tires, lights, cargo securement, and any visible mechanical issues. Bald tires, broken lights, and unsecured cargo are evidence of maintenance failures or loading violations.
Photograph your own injuries before medical treatment alters their appearance. Bruising, lacerations, and swelling look different after treatment begins. These photos document the immediate impact.
Do not give a recorded statement to anyone except the police at the scene. The trucking company’s adjuster may approach you. Politely decline. Anything you say can be used to minimize your claim.
What NOT to Do After a Truck Accident
What you don’t do after a truck accident is as important as what you do. Several common mistakes can damage your case before you even speak to an attorney.
Do not apologize or admit fault at the scene. Louisiana follows comparative fault rules. Even a casual “I’m sorry” can be reframed as an admission by the defense.
Do not give a recorded statement to the trucking company’s insurance adjuster without legal counsel. Adjusters are trained to ask questions that elicit responses useful for reducing your claim. You are not required to provide a recorded statement.
Do not sign any documents from the trucking company or its representatives at the scene. This includes medical authorization forms. These forms can give the insurance company access to your entire medical history, not just records related to the accident.
Do not post about the accident on social media. Insurance companies monitor claimants’ accounts. A photo of you smiling at a family event can be used to argue your injuries are not serious. Keep your accounts private and do not discuss the case online.
Do not wait to seek medical attention. Delayed treatment creates gaps in your medical timeline. Defense attorneys use these gaps to argue your injuries are either not related to the accident or not as serious as claimed.
Do not accept an early settlement offer. The first offer from the trucking company’s insurer is almost always undervalued. It comes before the full extent of your injuries is known and before your attorney has gathered the evidence needed to calculate your actual damages.
Do not repair or dispose of your vehicle before it has been inspected by your attorney’s expert. Your vehicle is evidence. Damage patterns, point of impact, and structural deformation tell the story of the crash.
Getting Medical Treatment After a Truck Accident
Go to the emergency room immediately after any truck accident, even if you feel fine. An 80,000-pound fully loaded semi-truck striking a 4,000-pound sedan creates forces that cause injuries not immediately apparent due to adrenaline.
Common truck accident injuries include traumatic brain injury, spinal cord damage, multiple fractures, internal organ damage, and crush injuries. Some of these injuries are not immediately apparent. Adrenaline masks pain. Internal bleeding may not produce symptoms for hours.
Go to the emergency room. Tell the ER physician every symptom, even ones that seem minor. A headache could indicate a concussion. Numbness could indicate nerve damage. Medical records from your first visit establish the baseline for your injury claim.
Follow up with your primary care physician or specialists as directed. Attend every appointment. The connection between your injuries and the truck accident must be documented by medical professionals through an unbroken chain of treatment records.
Keep every medical record, bill, and receipt. This includes prescriptions, physical therapy records, and mileage to medical appointments. These documents establish your economic damages.
Do not skip appointments. Insurance adjusters look for gaps in treatment. A two-week gap between appointments becomes “the claimant’s injuries resolved” in their adjuster notes. Morris & Dewett works directly with treating physicians to make sure records accurately reflect the injury and the treatment plan.
How Louisiana’s Comparative Fault Rule Affects Your Truck Accident Case
Louisiana follows a 51% bar comparative fault rule under La. C.C. Art. 2323. This threshold took effect on January 1, 2026, as part of Louisiana’s tort reform changes.
Here is what it means. If you are 51% or more at fault for the accident, you recover nothing. Zero. If you are 50% or less at fault, your recovery is reduced by your percentage of fault. A driver who is 20% at fault on a case worth $500,000 recovers $400,000.
Trucking companies and their insurers will attempt to shift fault onto you. This is their primary defense strategy. Common fault-shifting tactics include claiming you were in the truck’s blind spot, alleging you were speeding, or arguing you failed to yield the right of way.
This is why scene evidence and witness statements matter so much. Photographs of the impact point, skid marks, traffic camera footage, and witness accounts all establish what actually happened. Without this evidence, the fault question becomes your word against the trucking company’s narrative.
Insurance adjusters build their strategy around pushing your fault percentage above 50%. Morris & Dewett works with accident reconstructionists to establish fault percentages before the insurance company builds their case. Learn more about determining fault in truck accidents.
The Prescriptive Period: Louisiana’s Filing Deadline
Louisiana’s prescriptive period for personal injury is two years from the date of injury under La. C.C. Art. 3493.1. This deadline took effect on July 1, 2024.
This changed from three years under the previous law.
Claims against government entities may have shorter deadlines. If a LaDOTD vehicle or a municipal truck was involved, the filing requirements and timelines are different and often more restrictive.
The clock starts on the date of the accident, not the date you discover the full extent of your injuries. There are limited exceptions for certain circumstances, but the general rule applies to most truck accident cases.
Filing an insurance claim is not the same as filing a lawsuit. The lawsuit must be filed within the prescriptive period. If you miss this deadline, your case is barred regardless of how strong the evidence is.
When to Call a Truck Accident Attorney
The sooner you contact an attorney, the better your case is preserved. Trucking companies send investigators to the scene within hours. Their legal teams begin building a defense on day one. You need someone working on your side with equal urgency.
An attorney experienced in truck accident cases can send a preservation letter immediately. This stops the trucking company from destroying evidence on their normal retention schedule. An attorney who understands FMCSA regulations knows what evidence to request and where to find it, including the carrier’s obligations under DOT regulations.
Morris & Dewett sends spoliation preservation letters within 24 hours of engagement. We work with accident reconstructionists, trucking industry experts, and medical professionals to build cases from the evidence up. We have handled truck accident cases across Louisiana for 25 years.
What Compensation Does Louisiana Law Allow After a Truck Accident?
Louisiana law divides truck accident damages into categories. Understanding these categories helps you evaluate whether a settlement offer accounts for the full scope of your losses.
Economic damages include medical expenses, both past and future. They include lost wages from missed work and loss of earning capacity if your injuries affect your ability to work long-term. Property damage to your vehicle, rehabilitation costs, and out-of-pocket expenses are also economic damages. These are calculated from documentation.
Non-economic damages include pain and suffering, mental anguish, loss of enjoyment of life, and loss of consortium. These damages do not have receipts. They are based on the severity and duration of your injuries and their impact on your daily life.
UM/UIM
Uninsured/Underinsured Motorist coverage. A provision in your own auto insurance policy that pays you when the at-fault driver has no insurance (UM) or not enough insurance (UIM) to cover your damages. Louisiana law requires insurers to offer it, and it can stack across multiple vehicles on your policy.
Your own UM/UIM coverage may provide additional recovery if the truck’s policy is insufficient to cover your damages. This is separate from the claim against the trucking company.
Punitive damages are available in Louisiana only for drunk driving or wanton and reckless conduct under La. C.C. Art. 2315.4. These are rare but applicable when the evidence supports extreme misconduct.
Louisiana’s direct action statute, La. R.S. 22:1269, allows you to sue the insurance company directly. Most states do not allow this. It means the insurer is a named defendant in your lawsuit, not just a behind-the-scenes payer. Learn more about truck insurance requirements in Louisiana.
