How Is Fault Determined in a Louisiana Car Accident?

December 26, 2025

Fault in a Louisiana car accident is determined by evidence, state traffic laws, and Louisiana’s comparative fault rules. Louisiana is a fault-based state, which means the driver—or drivers—whose negligence caused the crash are legally responsible for the resulting damages. Insurance adjusters, investigators, and sometimes juries examine the behavior of every party involved and assign a percentage of fault to each. Because fault can significantly impact compensation, especially under Louisiana’s comparative fault system, injured people benefit from working with a law firm that understands the legal standards, the evidence required, and how to protect their rights.

At The Hinch Firm Trial Attorneys, helping injured clients navigate these rules is central to our work. Our firm handles car accident claims throughout Lake Charles and surrounding communities and is committed to ensuring our clients understand how fault is determined and what it means for their case.

Understanding Louisiana’s Fault System After a Car Accident

Louisiana uses a fault-based (tort) system, meaning the at-fault driver is financially responsible for the damages they cause. Unlike “no-fault” states where drivers file claims with their own insurers first, Louisiana requires injured people to pursue compensation from the driver whose negligence contributed to the collision.

To determine fault, several factors are considered:

  • Traffic laws
  • Driver conduct
  • Evidence collected at the scene
  • Witness statements
  • Expert analysis
  • Louisiana’s comparative fault rules

Fault is rarely black and white. In many cases, multiple drivers share responsibility, and each party’s compensation is adjusted based on their percentage of fault. This is why the details of the accident—and how the evidence is presented—matter so much.

Louisiana’s Comparative Fault Rules: How Percentages Impact Compensation

Fault determination doesn’t end with identifying who caused the crash. It also involves assigning percentages of fault among all responsible parties.

Pure Comparative Fault (Current System)

For now, Louisiana applies a pure comparative negligence rule. This means:

  • An injured person can recover compensation even if they were mostly at fault.
  • Their recovery is reduced by their percentage of fault.

For example:

If a driver is awarded $100,000 but found 30% at fault, they can still recover $70,000. This system is designed to ensure that people are not barred from financial recovery simply because they made a mistake. It also allows courts to assign fault fairly based on each party’s actions.

Upcoming Change: The 51% Bar Rule

Louisiana recently enacted legislation that will modify the comparative fault system for certain cases going forward. Once fully in effect, individuals who are 51% or more at fault will be barred from recovering compensation. This change makes the analysis of fault—and the evidence supporting it—even more crucial in accident claims.

Because fault percentages directly affect the amount of compensation someone may receive, injured people often benefit from having an attorney who can help ensure their fault is not overstated by insurance companies.

How Louisiana Law Defines Negligence in Car Accident Cases

In Louisiana, fault is closely tied to negligence, which is evaluated through a legal analysis known as the duty–risk framework. This framework asks several questions:

1. Did the driver owe a duty of care?

Every driver has a legal duty to:

  • Operate their vehicle safely
  • Follow traffic laws
  • Maintain a proper lookout
  • Adjust to road, weather, and traffic conditions

2. Did the driver breach that duty?

A breach may include:

  • Speeding
  • Drunk or drug-impaired driving
  • Distracted driving
  • Running a red light or stop sign
  • Following another vehicle too closely
  • Unsafe lane changes

3. Did the breach cause the crash?

This requires proving the negligent action was a direct cause of the accident.

4. Were the damages a foreseeable result of the breach?

Louisiana uses the “scope of risk” test to determine whether the harm someone suffered was the type of harm the breached duty was designed to prevent.

5. Did the crash cause actual damages?

Damages often include:

  • Medical bills
  • Lost wages
  • Reduced earning capacity
  • Pain and suffering
  • Property damage

If these elements are met, a driver may be considered at fault.

When a negligent driver harms another person, Louisiana law allows the injured party to file a claim for damages. The Hinch Firm Trial Attorneys represents clients in car accident claims through our personal injury division.

Evidence Used to Determine Fault in Louisiana Car Accidents

Fault is determined based on the quality and strength of the evidence. Insurance companies and courts analyze a wide range of information, including:

Police Reports

Law enforcement officers typically investigate accident scenes and prepare a crash report detailing:

  • What they observed upon arrival
  • Statements from involved drivers and witnesses
  • Citations issued for traffic violations
  • Diagrams or officer opinions about contributing factors

While a police report is influential, it is not the final word on fault. Insurers and courts may consider additional evidence.

Physical and Scene Evidence

This includes:

  • Skid marks
  • Vehicle damage patterns
  • Roadway debris
  • Traffic signal or signage placement
  • Surveillance or dash camera footage
  • Weather and visibility conditions

Accident reconstruction experts often use this information to determine how the crash occurred.

Driver and Witness Statements

Credible witness accounts can significantly impact fault determination. Objective witnesses can confirm or contradict claims made by the drivers involved.

Electronic and Digital Data

Modern vehicles frequently contain event data recorders, which may reveal:

  • Speed before impact
  • Brake application
  • Steering actions
  • Seatbelt use

In some cases, cellphone records reveal whether texting or distracted driving contributed to the crash.

Medical Records

These help establish the link between the accident and the injuries sustained.

Expert Testimony

Experts such as accident reconstructionists, engineers, and medical specialists often play a role when fault is disputed or the accident involves complex factors. Because fault is evidence-driven, it is essential for injured people to preserve as much information as possible immediately after the crash—photos, contact details, and vehicle information all matter.

Legal Presumptions That Influence Fault Determination

Certain types of collisions trigger presumptions of fault under Louisiana law.

Rear-End Collisions

Louisiana follows a well-established presumption that the rear driver is at fault in a rear-end collision. The logic is simple: drivers have a duty not to follow another vehicle more closely than is reasonable.

However, this presumption can be overcome if evidence shows:

  • The lead driver stopped suddenly for no justifiable reason
  • Brake lights were not functioning
  • A third vehicle initiated the crash

Left-Turn Accidents

Drivers making left turns must yield to oncoming traffic. If a collision occurs during a left turn, the turning driver is often presumed at fault unless they can show:

  • The oncoming driver was speeding
  • The oncoming vehicle ran a red light
  • They had a protected left-turn signal

These presumptions play an important role in fault determination, but they can be challenged with strong evidence.

Shared Fault in Louisiana Car Accidents

It is common for more than one driver to share responsibility for the same crash. Under Louisiana’s comparative fault system, each driver is assigned a percentage based on how much their conduct contributed to the accident.

Examples include:

  • A driver who speeds through a yellow light colliding with a vehicle making an unsafe left turn
  • A rear-end collision where the lead driver had malfunctioning brake lights
  • A two-car collision where both drivers were distracted

Even when a driver believes they may have contributed to a crash, they may still pursue compensation. The key is understanding how fault is distributed and how the evidence supports or challenges those allocations.

Other Parties Who May Share Fault

Fault isn’t limited to drivers. Other parties may be responsible:

Employers

If a driver was working at the time of the crash, their employer may be liable under the legal doctrine known as respondeat superior.

Vehicle Owners

Owners may be responsible if they negligently entrusted their vehicle to an unsafe or unlicensed driver.

Manufacturers and Mechanics

Defective brakes, tires, or steering components can cause or contribute to serious collisions.

Government Entities

Poor road design, missing signage, or malfunctioning traffic signals may result in municipal or state liability.

Understanding all potential sources of liability is critical for ensuring the injured party receives full compensation.

Why Fault Determination Matters So Much

For injured people, how fault is assigned affects:

  • Eligibility for compensation
  • The amount they can recover
  • Whether their own insurance or the other driver’s insurance will pay
  • Whether litigation becomes necessary
  • How insurers negotiate or attempt to reduce claims

Insurance companies often try to shift more fault onto injured people to minimize payouts. This is why working with an experienced trial attorney matters—someone who knows what evidence to look for, how to counter insurer arguments, and how to build a strong case.
