A jackknife wreck happens when a big rig’s trailer loses traction and swings perpendicular to the cab, folding the truck like a pocketknife. The trailer may cross multiple lanes, strike several vehicles, or scatter cargo across the roadway.
The truck accident claim process that follows can be far more complicated than a typical fender-bender claim because multiple parties, commercial insurance policies, and trucking records may be involved.
Learn how liability works in Louisiana, why the Direct Action statute matters, the step-by-step claim process, and the evidence you need to protect yourself after a jackknife wreck.
What Makes a Jackknife Wreck Different From a Regular Truck Crash
A trailer can lose traction due to hard braking, wet or oily pavement, a downhill grade, an unbalanced load, or a brake imbalance between the cab and the trailer. Once the trailer begins swinging sideways, the truck can cross several lanes and strike multiple vehicles.
As a result, a jackknife claim may involve several vehicles, cargo spills, federal safety records, and multiple potentially liable parties.
How Liability Is Determined in a Louisiana Jackknife Wreck
For wrecks on or after January 1, 2026, Louisiana follows a modified comparative fault system under Louisiana Civil Code Article 2323. If you are less than 51% at fault for a wreck, your compensation may be reduced according to your percentage of fault. If you are 51% or more at fault, you cannot recover damages.
Depending on what caused the crash, potentially responsible parties can include:
- The truck driver
- The motor carrier
- The company that loaded or shipped the cargo
- A maintenance contractor
- A manufacturer of a defective truck or component
Federal Motor Carrier Safety Administration (FMCSA) regulations may also help determine responsibility for a jackknife wreck. Rules cover areas such as hours of service, driver qualifications, vehicle inspections, and drug and alcohol testing. Records showing violations of these safety requirements may help establish what happened and whether a safety failure contributed to the crash.
How the Louisiana Direct Action Statute May Affect a Claim
Louisiana’s Direct Action statute, Louisiana Revised Statutes 22:1269, limits when an injured person may name an insurance company in a lawsuit. In most cases, you cannot sue an insurer just because it provides coverage for the person or business responsible for the wreck.
The law does allow a direct action against an insurer in certain situations. For example, this may apply if the insured is bankrupt or insolvent, has died, or cannot be served with the lawsuit under the conditions set by the statute.
Step-by-Step Guide to the Truck Accident Claim Process After a Jackknife
Every claim is different, but acting early can help preserve evidence and document your losses.
| Step | What to Do |
| Get medical care and report the wreck. | Get medical attention for any injuries first, and make sure law enforcement documents the crash. |
| Preserve evidence from the scene. | If you can safely do so, photograph the truck, vehicle damage, skid marks, cargo debris, road conditions, and vehicle positions. Get contact information from witnesses. |
| Send a preservation letter. | Electronic truck data, driver logs, dashcam footage, and other evidence may not be kept indefinitely. A preservation letter asks the trucking company to keep potentially important evidence from being deleted or destroyed. |
| Request trucking records. | Driver, employment, safety, and vehicle records can provide information about the driver, truck, and events leading up to the wreck. |
| Notify the insurance companies. | Report the wreck to your own insurer. Be cautious about giving a recorded statement to the trucking company’s insurer. |
| Document your damages. | Keep medical bills, treatment records, wage-loss documentation, property damage estimates, and receipts for expenses related to the wreck. |
| Negotiate or file a lawsuit when necessary. | A demand letter may begin negotiations. If the parties cannot reach an agreement, a lawsuit may be necessary. Louisiana imposes a deadline for filing an injury lawsuit. |
Under Louisiana Civil Code Article 3493.1, personal injury actions arising on or after July 1, 2024, are subject to a two-year prescriptive period (statute of limitations) that begins when the injury or damage occurs. Missing the applicable deadline can prevent you from pursuing your claim.
Evidence You Need to Support a Louisiana Jackknife Claim
Important evidence can be lost or overwritten after a commercial truck wreck, especially electronic data. Acting quickly can help preserve that evidence before it disappears.
Trucking records may include engine control module data, hours-of-service logs, the driver qualification file, post-crash drug and alcohol testing results, and vehicle maintenance history.
Crash-scene evidence can include photographs, dashcam or traffic-camera footage, the police report, witness statements, and, when appropriate, crash reconstruction evidence.
Medical and financial evidence may include treatment records, imaging results, physician documentation of future care needs, wage-loss documentation, and receipts for wreck-related expenses.
