Common Causes of Truck Accidents
Commercial trucks on Louisiana highways, including Interstate 20 and Interstate 49 through Shreveport, create serious risks when drivers or carriers fail to follow safety standards. The Federal Motor Carrier Safety Administration identifies several recurring causes in large truck crashes. Each one involves a specific failure that can be traced to the driver, the trucking company, or a third party responsible for the vehicle.
Driver fatigue is one of the most frequent causes. A truck driver who exceeds federal hours of service limits or falsifies log entries operates the vehicle with impaired reaction time and judgment. Distracted driving, including cell phone use or adjusting GPS systems while operating a vehicle weighing up to 80,000 pounds, also accounts for a significant share of collisions.
Speeding and aggressive driving reduce a truck driver's ability to stop or maneuver safely. A fully loaded 18 wheeler traveling at highway speed requires approximately 525 feet to come to a complete stop. That distance increases on wet roads, which are common during Louisiana's heavy rain seasons. Impaired driving due to alcohol or drug use, though less common in commercial trucking than in passenger vehicles, still contributes to crashes in this industry.
Mechanical failures cause accidents when brakes, tires, steering systems, or coupling devices are not properly maintained. Overloaded or improperly secured cargo shifts the vehicle's center of gravity and can cause rollovers, particularly on curved highway ramps and exits. Each of these causes points to a preventable failure by someone in the chain of commercial trucking operations.
Federal Regulations and Trucking Safety
The FMCSA enforces a set of regulations that govern how trucking companies and their drivers must operate. These rules exist because the size and weight of commercial trucks make any collision with a passenger vehicle disproportionately dangerous. When a trucking company or driver violates these regulations, that violation can serve as direct evidence of negligence in a civil lawsuit.
Hours of Service rules under 49 CFR Part 395 limit property carrying drivers to 11 hours of driving within a 14 hour window after 10 consecutive hours off duty. Drivers must also take a 30 minute break after 8 cumulative hours of driving. The 60/70 hour weekly limit prevents drivers from accumulating excessive time behind the wheel over a seven or eight day period. Electronic logging devices are now mandatory for most commercial motor vehicles, replacing paper logs that were easier to falsify.
Maintenance and inspection requirements under 49 CFR Parts 393 and 396 require carriers to systematically inspect, repair, and maintain all commercial motor vehicles under their control. Drivers must complete pre trip and post trip inspections and document any defects. The carrier is responsible for ensuring that no vehicle with a known safety defect operates on public roads. Violations of these maintenance standards are documented during roadside inspections and are accessible through FMCSA's Safety Measurement System.
Drug and alcohol testing regulations under 49 CFR Part 382 require pre employment testing, random testing, post accident testing, and testing based on reasonable suspicion. A carrier that fails to implement a compliant testing program or that allows a driver with a positive result to continue operating assumes significant liability.
Liability in Louisiana Truck Accident Cases
Louisiana law provides several theories of liability that apply to truck accident cases. The driver may be directly liable for negligent operation of the vehicle. The trucking company, as the driver's employer, is typically liable under the doctrine of respondeat superior for the driver's actions within the scope of employment. Louisiana Civil Code Article 2320 establishes employer liability for the fault of employees.
Carriers also face direct liability for their own negligence in hiring, training, supervising, and retaining drivers. A company that hires a driver without checking the FMCSA Drug and Alcohol Clearinghouse or that ignores a pattern of safety violations on a driver's record may be independently negligent. Third party maintenance companies that service the vehicle's brakes, tires, or other systems can also bear liability if their work was defective.
Louisiana follows a comparative fault system under La. C.C. art. 2323. For accidents occurring on or after January 1, 2026, a plaintiff who is found to be 51 percent or more at fault cannot recover damages. For accidents before that date, Louisiana's pure comparative fault system applies, and a plaintiff can recover reduced damages regardless of their percentage of fault. This change in the law makes the determination of fault percentages in truck accident cases more consequential than ever.
Cargo loading companies and freight brokers may also face claims depending on the circumstances. If improperly loaded cargo caused or contributed to the accident, the entity responsible for loading bears a share of fault. Louisiana courts assign fault percentages to each responsible party under La. C.C. art. 2323 and art. 2324.
Evidence That Matters in Truck Accident Claims
Truck accident cases generate more evidence than typical motor vehicle accident claims. Commercial trucks equipped with electronic logging devices record hours of service data that can reveal whether the driver was in compliance at the time of the crash. Many trucks also carry event data recorders that capture speed, braking, and other vehicle operation data in the seconds before a collision.
Federal regulations require carriers to retain driver qualification files, drug and alcohol testing records, vehicle maintenance records, and inspection reports. Under FMCSA rules, carriers must preserve certain records for specific periods. However, a trucking company that anticipates litigation may have a legal duty to preserve evidence beyond those standard retention periods. A spoliation letter sent promptly after the accident puts the carrier on formal notice to preserve all relevant records and electronic data.
Dashcam footage, traffic camera recordings, and witness statements all contribute to establishing what happened. In Shreveport, the Caddo Parish road network includes several high traffic corridors where commercial trucks are present in large numbers. Accident reconstruction experts can use physical evidence from the scene along with vehicle data to determine speed, point of impact, and the sequence of events.
The Legal Process After a Truck Accident
Louisiana law requires that a personal injury claim be filed within the applicable prescriptive period. For accidents occurring on or after July 1, 2024, the prescriptive period is two years from the date of the accident under the amended La. C.C. art. 3492. For accidents before that date, the prescriptive period is one year. Missing this deadline eliminates the right to file a lawsuit regardless of how strong the underlying claim may be.
Truck accident claims in Caddo Parish are filed in the First Judicial District Court. These cases often involve multiple defendants, including the driver, the trucking company, maintenance providers, and their respective insurance carriers. Louisiana's direct action statute, La. R.S. 22:1269, allows an injured party to name the liability insurer as a defendant in the lawsuit. This is distinct from most other states, where the insurer is not a named party.
Discovery in truck accident litigation typically includes requests for the carrier's safety records, driver qualification files, ELD data, maintenance logs, and insurance policy information. Depositions of the driver, safety director, and maintenance personnel help establish what the company knew and what steps it took or failed to take. Because trucking companies and their insurers often begin their own investigation within hours of an accident, prompt legal action helps ensure that evidence is preserved and that the injured party's rights are protected from the outset.
Louisiana law permits recovery of medical expenses, lost wages, loss of earning capacity, physical pain and suffering, mental anguish, and loss of enjoyment of life. In cases involving egregious conduct such as drunk driving by a commercial truck operator, exemplary damages may also be available under La. C.C. art. 2315.4.
