Can You Sue If a Louisiana Car Accident Was Partly Your Fault?

Can You Sue If a Louisiana Car Accident Was Partly Your Fault?

You may still have a claim if another driver, company, vehicle owner, manufacturer, or other person also caused the crash. Louisiana Civil Code article 2323 requires fault to be assigned among all persons who caused or contributed to an injury, death, or loss. Your share can reduce what you recover, and for crashes governed by the rule effective January 1, 2026, it can eliminate recovery at 51 percent.

Partly at fault does not mean automatically liable for everything, and it does not mean automatically entitled to money. You still must prove that another person’s fault contributed to the collision and caused compensable damage. Insurance coverage, collectibility, medical causation, filing deadlines, and other defenses can also affect the result.

Why Does the Crash Date Change the Rule?

Act 15 of 2025 amended Louisiana Civil Code article 2323 and became effective January 1, 2026. The amendment changed Louisiana from a pure comparative fault system to a modified system with a 51 percent bar.

The Act does not say that it applies retroactively. Civil Code article 6 provides that, absent a contrary legislative expression, substantive laws apply prospectively only. Because the amendment changes whether an injured person may recover at all, the practical starting point is the date on which the crash and injury occurred:

• Crash before January 1, 2026: analyze comparative fault under the law in effect before the amendment.
• Crash on or after January 1, 2026: apply the amended 51 percent bar, subject to any claim-specific issue or exception.

The filing date ordinarily does not convert an older crash into a 2026 crash. For example, filing suit in 2026 over a December 2025 collision does not by itself change when the underlying injury occurred. A contested transition issue should still be reviewed using the Act, Article 6, the pleadings, and any controlling court decision available when the issue is decided.

Crashes Before January 1, 2026: The Prior Pure Comparative Fault Rule

Under the prior version of Article 2323, a person’s damages were reduced in proportion to that person’s negligence. There was no 51 percent cutoff in the statute.

Suppose a jury found total damages of $200,000 and assigned 70 percent of the fault to the injured driver and 30 percent to the other driver. Under the prior rule, the injured driver would not automatically lose the entire claim because the driver’s fault exceeded half. The comparative-fault calculation would reduce $200,000 by 70 percent, leaving $60,000 before other legal, coverage, or collection issues.

This did not mean that a driver could recover when nobody else was legally at fault. If the evidence showed that the injured driver was 100 percent responsible, there would be no share to recover from another person. The prior law preserved a proportionate recovery only when another person’s fault also contributed to the damage.

Crashes on or After January 1, 2026: The 51 Percent Bar

The amended Article 2323 creates two different outcomes:

• If the injured person’s negligence is less than 51 percent, damages are reduced in proportion to that negligence.
• If the injured person’s negligence is 51 percent or more, the person is not entitled to recover damages.

The line between 50 and 51 percent can therefore decide the entire negligence claim. At 50 percent, the claimant may recover one-half of proven damages. At 51 percent, the statute generally bars recovery.

Article 2323 also now directs that, when comparative fault is submitted to a jury, the jury must be instructed on the effect of the Article. The jury is not merely choosing abstract numbers. In a post-2025 crash, crossing the 51 percent line changes the legal result.

The intentional-tort provision is different

Article 2323(C) states that when injury results partly from the injured person’s negligence and partly from an intentional tortfeasor’s fault, the injured person’s claim is not reduced. An ordinary speeding, turning, lane-change, or following-too-closely crash is usually analyzed as negligence. A deliberate vehicle attack or another intentional act can require a different analysis, including separate insurance questions.

How Do Fault Percentages Change the Recovery?

These examples assume $250,000 in proven damages and a solvent responsible party. They isolate comparative fault only. They do not account for policy limits, liens, medical-expense rules, causation disputes, or other defenses.

A left-turn crash with speeding evidence

A driver turns left across traffic. The oncoming driver has the right of way but is shown by video and vehicle data to have been traveling well above the speed limit. A factfinder may decide that both drivers contributed. The turning driver’s fault does not make the oncoming driver’s conduct irrelevant, and the oncoming driver’s right of way does not necessarily erase evidence of excessive speed.

A rear impact after a sudden lane change

One vehicle strikes another from behind, but the front vehicle had just moved into the lane with too little space. The rear driver may be accused of following too closely or failing to brake, while the lane-changing driver may be accused of making an unsafe movement. Dash-camera footage, impact location, event data, and witness accounts can move the percentages in either direction.

Two drivers who both claim a green light

A police report may document competing accounts without resolving them. Signal timing, camera footage, 911 timestamps, independent witnesses, vehicle positions, and damage patterns may determine whether one driver ran the light or whether both drivers failed to avoid a developing hazard.

A multi-vehicle collision

Article 2323 directs the factfinder to determine the fault of all persons who caused or contributed to the loss, including nonparties and persons whose identities are not known or reasonably ascertainable. A chain-reaction crash may involve more than a simple comparison between the claimant and the named defendant. Commercial drivers, employers, road contractors, vehicle manufacturers, and unidentified motorists may need to be investigated when the facts support their involvement.

Who Decides Whether You Were 10, 50, or 51 Percent at Fault?

An insurance adjuster’s first percentage is not a court judgment. It is a claim position. The parties may negotiate a settlement based on the evidence and litigation risk. If the case is tried, the judge or jury assigns fault based on the admissible evidence and applicable duties.

A traffic citation can be important, but it does not automatically answer every civil-fault question. The civil investigation may include evidence the responding officer did not have at the roadside, such as later-obtained video, electronic vehicle data, phone records, medical evidence, or testimony from additional witnesses.

Evidence commonly used in a disputed-fault crash includes:

• Scene photographs and video showing lanes, debris, skid or tire marks, traffic controls, lighting, weather, and sight lines
• Original dash-camera, business, residential, traffic, doorbell, and witness video files
• The crash report, supplements, 911 audio, dispatch records, and available body-camera or vehicle-camera footage
• Independent witness names, locations, and recorded recollections
• Vehicle damage, crush patterns, paint transfer, airbag deployment, and final resting positions
• Event data recorder information, telematics, fleet tracking, and electronic logging data when available
• Phone and application records when distraction is genuinely at issue
• Road design, construction-zone, signal-timing, maintenance, and prior-notice records when a roadway condition contributed
• Medical records connecting the collision to the claimed injuries and limitations

What Should You Do If the Insurer Says You Share the Blame?

1. Do not accept a percentage without the supporting evidence. Ask what facts, statements, photographs, video, or rules the adjuster relied on.
2. Preserve time-sensitive proof. Nearby video can be overwritten, vehicles can be sold or repaired, and electronic data can disappear.
3. Keep your account factual. Do not guess about speed, distance, timing, or blame. Say what you actually observed and identify what you do not know.
4. Correct objective errors. Preserve documents showing the correct lane, direction, traffic control, vehicle ownership, insurance, and witness information.
5. Do not sign a release before the fault and medical records are understood. A release can end the claim even if later evidence changes the liability picture.
6. Document damages separately from fault. Treatment records, restrictions, wage records, repair evidence, and daily limitations still must be proved.
7. Have the crash date and deadline checked. The date determines which comparative-fault rule starts the analysis, while a separate prescription rule controls how long you have to file suit.

Comparative Fault Is Not the Only Rule That Can Limit a Claim

Civil Code article 3493.1 provides a general two-year prescriptive period for delictual actions, running from the day injury or damage is sustained. That current article became effective July 1, 2024. Older crashes, specialized claims, governmental defendants, wrongful-death issues, and other circumstances can involve different timing questions.

Do not confuse the fault-rule change on January 1, 2026 with the separate deadline change that took effect in 2024. One rule concerns how responsibility affects recovery. The other concerns the time to bring a claim. Our Louisiana prescription guide explains the deadline issue in more detail.

Other rules can also affect recovery even when your fault remains below 51 percent. Those can include insurance-policy limits, exclusions, uninsured or underinsured motorist coverage, proof of medical causation, collectibility, and claim-specific statutes. Comparative fault is a central calculation, but it is not a complete case valuation.

Review the evidence before accepting a fault percentage

An adjuster’s first percentage is a claim position, not a judgment. If the number matters to whether you can recover, ask what evidence supports it and preserve any video, vehicle data, photographs, and witnesses that point the other way.
