Starting January 1, 2026, Louisiana changed how fault works in car and truck accident cases. This new law is called the 51 percent fault rule.

Under this rule, a driver cannot get any money if they are found more than 50 percent responsible for a crash. Even if another driver also made a mistake, being mostly at fault means no recovery at all. Read more about it here.
This change affects all drivers in Louisiana, but it impacts truck wreck claims more than car wrecks.

Louisiana courts now look closely at who caused a crash. Fault is split into percentages. If your share is over 50 percent, you lose the right to recover money for injuries, car repairs, lost wages, and medical bills.
This makes evidence very important. Things like vehicle condition, driving behavior, and maintenance records can change how fault is decided.
How Truck Wreck Claims Are More Impacted
Truck accidents in Louisiana are handled differently from car accidents. Big trucks must follow strict safety and maintenance rules. After a truck wreck, insurance companies and lawyers review many records.
They look at truck maintenance logs, inspection reports, driver hours, and electronic data. They also look closely at the injured driver’s actions and vehicle condition.

If the injured driver’s car had worn tires, bad brakes, or other problems, the truck company may argue that the driver caused most of the crash. Under the 51 percent rule, this can block all compensation.
Truck wrecks often cause serious injuries. Because medical costs are high, insurance companies fight harder to shift blame. Even a small change in fault can decide whether a person gets paid or gets nothing.

How Car Wreck Claims Compare
Car wreck cases are usually simpler. Many involve clear fault, like rear-end crashes or running a red light. There are fewer records and fewer experts involved.
Car maintenance can still matter, but these cases do not usually involve the same level of investigation as truck accidents. The 51 percent rule still applies, but it is less common for fault to be heavily disputed.

Why Vehicle Maintenance Is Now More Important
Under Louisiana’s new law, poor vehicle maintenance can hurt your case. If a crash involves brake failure, tire blowouts, or steering problems, fault may shift to the driver.
Courts may ask whether the driver took care of their vehicle. Repair receipts and service records can help prove responsibility was not yours.
Without proof of maintenance, a driver may be blamed for causing the crash.

What Louisiana Drivers Should Know
This new law affects drivers across Baton Rouge, Shreveport, Gonzales, New Orleans, Lafayette, and all of Louisiana. Even partial responsibility can lead to serious financial loss.
The new rule makes one thing clear. Safe driving and proper vehicle care matter more than ever. In serious crashes, especially truck wrecks, the difference between 49 percent fault and 51 percent fault can change everything.
Understanding Louisiana’s 51 percent fault rule can help drivers better protect themselves after a car or truck accident.
