Louisiana's modified comparative fault system reduces your crash recovery by your fault share and bars it completely only at 51 percent or more. Strong documentation, including photographs, data recorder output, and witnesses, keeps that share as low as possible. Since January 1, 2026, La. Civ. Code art. 2323, as amended by Acts 2025, No. 15, bars recovery when your share of fault is 51% or more.
How Modified Comparative Fault Shapes Your Crash Claim
Louisiana's modified comparative fault rule bars a crash claim based on the claimant's fault percentage only at 51 percent or more. If you are 10 percent at fault, your recovery is reduced by 10 percent. If you are 70 percent at fault, your recovery is barred. The claim survives at every level below 51 percent, where the question is how much, not whether.
This does not mean fault allocation is unimportant. Each percentage point of fault directly reduces the dollar value of your recovery. In a substantial crash claim, a 15-point difference in fault allocation can shift the recovery significantly. The insurer knows this and will attempt to assign the highest fault percentage the evidence can support.
Reducing Your Fault Share Through Crash Evidence
In a modified comparative fault state, reducing your assigned fault percentage by even a few points translates into direct financial gain. The evidence that accomplishes this comes from multiple sources: scene photographs documenting road conditions and vehicle positions, dashcam or surveillance footage showing the collision sequence, and the event data recorder from both vehicles.
The police crash report provides the starting narrative, but it is not the final word. If the officer's account assigns you partial fault based on incomplete information, independent evidence can shift the assessment. Traffic camera footage, witness statements collected separately from the report, and expert accident reconstruction all carry weight in Louisiana. Each piece that contradicts the insurer's fault theory reduces the percentage and increases the dollars.
A worked example with Louisiana’s rule applied
Take a crash claim with documented losses like these:
| Medical bills | $17,800 |
| Lost wages | $5,200 |
| Other out-of-pocket costs | $650 |
| Pain and suffering (3.0× medical) | $53,400 |
| Gross value before fault | $77,050 |
Under Louisiana’s 51% bar, percentages behave like a cliff edge. At 50% fault this claim still pays $38,525; at 51% it pays $0. One percentage point moves $38,525, which is why the fault number in the adjuster's file is worth arguing about with evidence, not estimates.
Building the Crash Evidence File in Louisiana
The strongest crash claims are built on layered evidence. Witness statements provide context that photographs and data alone cannot — the color of the traffic light, the speed of a lane change, the behavior of a driver moments before impact. Collect contact information from every witness at the scene before they leave.
Surveillance cameras at nearby businesses, traffic monitoring systems, and residential doorbell cameras may have captured the collision from angles no witness observed. This footage is typically overwritten within 48 to 72 hours. Identifying camera locations and requesting footage preservation before the recording cycles out is one of the most time-sensitive tasks after any crash in Louisiana. Delay here means permanent evidence loss.

Questions
Louisiana questions
Does shared fault destroy my crash claim in Louisiana?
Only if your share reaches 51 percent. Louisiana follows modified comparative fault, meaning your claim survives at fault levels below that. Your recovery is reduced by your assigned fault percentage — 30 percent fault means 70 percent of total damages. The dispute is always about the size of your fault share, and evidence is what determines that number.
How is the fault percentage determined in a Louisiana crash case?
Fault percentage is built from crash-scene evidence: police reports, photographs, vehicle data recorder output, witness statements, and sometimes expert reconstruction. The insurer proposes a number, but that number is not final. Stronger documentation gives you leverage to challenge the assessment and push the assigned percentage lower.
If I am mostly at fault for a crash in Louisiana, can I still recover damages?
No. Modified comparative fault bars recovery at 51 percent fault or more. A claimant at 80 percent fault collects nothing. The insurer will attempt to assign the highest percentage possible, so your crash-scene evidence is the primary tool for limiting that number and increasing your recovery.
