For a Louisiana crash on or after January 1, 2026, the difference between being found 50% at fault and 51% at fault can determine whether an injured person recovers part of their damages or nothing from other responsible parties. Under the state’s current approach, partial fault doesn’t always leave an injured driver with a claim.
This post explains the current law in general terms. It doesn’t provide legal advice for any individual claim.
How Louisiana’s 51% Fault Threshold Changes Recovery
Louisiana law bars recovery when an injured person’s share of fault is 51% or more. Under Louisiana Civil Code Article 2323, as amended by Act 15 of 2025, someone who’s less than 51% at fault can still recover damages, but the recovery is reduced by that person’s fault percentage.
This system is called modified comparative fault. Responsibility for a collision is divided among the people whose conduct contributed to the injury, death, or loss. Louisiana previously used pure comparative fault, which allowed an injured person to recover the portion of damages caused by someone else even when the injured person was more than 50% at fault.
A simple example shows why one percentage point matters. If total damages are $100,000 and the injured driver is 50% at fault, the recoverable amount is $50,000. If that driver’s fault is 51%, the statute prevents recovery from the other responsible party or parties.
The Crash Date Determines Which Rule Applies
The collision date, not the date an insurance claim or lawsuit is filed, determines which fault system applies. Act 15 of 2025, also known as House Bill 431, took effect on January 1, 2026.
That creates a clear dividing line:
- Crashes before January 1, 2026. The prior pure comparative fault system applies, even if the claim remains pending or a lawsuit is filed after that date.
- Crashes on or after January 1, 2026. The modified comparative fault system applies, including the bar on recovery when the injured person’s fault is 51% or higher.
Keep a record of the collision date with the police report, photographs, medical records, repair records, and insurance correspondence. The collision date recorded in the report identifies the legal framework governing fault and damages.
Why Evidence Matters Near the 51% Cutoff
A fault percentage isn’t simply an insurer’s label. The law requires the trier of fact, meaning the judge or jury deciding disputed facts, to determine the degree or percentage of fault of everyone who contributed to the loss. When comparative fault is submitted to a jury, the law also requires an instruction explaining its effect.
Because 51% is now a cutoff, the facts supporting a proposed percentage deserve close attention. An initial insurance assessment isn’t necessarily the final legal allocation of fault. Traffic controls, lane position, and each driver’s actions can affect how responsibility is assigned.
Useful evidence often includes:
- Crash-scene photographs showing vehicle positions, roadway conditions, debris, signs, and traffic controls.
- Witness names and contact information gathered before memories fade.
- Available video footage from nearby cameras, dash cameras, or vehicles involved in the collision.
- The police report, vehicle-damage documentation, and medical records connecting injuries to the crash.
Prompt documentation preserves the information needed to challenge an unsupported attempt to place 51% or more of the blame on the injured driver.
The Fault Threshold Doesn’t Change Filing Deadlines
The percentage assigned to an injured person determines whether fault blocks recovery. It doesn’t extend or replace the deadline for bringing a claim, which Louisiana law calls a prescriptive period.
Under Louisiana Civil Code Article 3493.1, the general prescriptive period for personal injury claims is two years for injuries occurring on or after July 1, 2024. Two years is a general rule, not a reason to wait. The applicable deadline for a particular claim depends on the parties involved and the facts of the injury.
There’s also a narrow but important distinction in Article 2323(C). When a loss results partly from a claimant’s negligence and partly from an intentional tort, meaning deliberate wrongful conduct, the claimant’s damages aren’t reduced under that subsection. Intentional conduct is treated differently from ordinary carelessness in a car accident.
A driver dealing with a disputed crash must track both issues: preserve evidence bearing on fault and act within the applicable prescriptive period. A strong account of fault won’t protect a claim brought too late, while a timely claim still depends on evidence of what occurred.
How We Review Disputed Car Accident Fault
We begin by confirming the accident date and the governing fault framework. We then organize the available evidence, claimed injuries and losses, and conduct of every party who contributed to the collision.
Our fourth-generation, family-owned firm has represented injury clients and their families in and around Monroe for more than 100 years. For car accident claims, Attorney Jeff Guerriero personally handles or oversees every claim that comes through our firm.
Our review examines the factual basis for a fault assessment rather than treating an insurer’s first version of events as the final word. Before accepting a determination, preserve the records described above and confirm the accident date.
