Trucking companies often begin investigating a crash right away. A carrier may send an adjuster, investigator, or crash expert to the scene within hours. While the injured person is still receiving treatment in Metairie or New Orleans East, the company may already be taking photos, speaking with witnesses, and collecting vehicle data.
That early start can put injured families at a disadvantage. Protecting a truck accident claim means saving evidence before it disappears, avoiding a rushed recorded statement, keeping clear records of your injuries and expenses, and watching the Louisiana filing deadlines that have changed twice in the past two years.
The Evidence Will Not Be Kept Forever
Commercial trucks store useful crash data. The engine control module may show speed, braking, throttle use, and fault codes. Electronic logging devices record the driver’s hours. Much of this information can disappear quickly.
Under 49 CFR 395.8, duty records and supporting documents must be kept for six months. Other data may be lost much sooner. A truck’s control module can be overwritten after it returns to service, while dashcam and telematics files may be deleted on their own schedules.
A written preservation letter can help stop that from happening. It should be sent early and list the records that must be saved. In the first week, this step may preserve key proof. By the third month, some of it may already be gone.
| Evidence | Who holds it | Realistic survival window |
| Engine control module data | Carrier or repair facility | Until the truck is repaired or returns to service |
| Records of duty status, ELD logs | Carrier | Six months under 49 CFR 395.8 |
| Post-accident drug and alcohol tests | Carrier | Must be collected within hours |
| Dashcam and telematics | Carrier or third-party vendor | Days to months, varies by contract |
| Roadside and business cameras | Third parties | Days to a few weeks |
| The truck and trailer themselves | Carrier, salvage yard | Until repaired, sold or scrapped |

Post-Accident Testing Runs on a Tight Clock
Post-accident testing may begin while the injured person is still at the hospital.
Under 49 CFR 382.303, a trucking company must test the driver in certain crashes. Testing is required after a fatal crash. It may also be required after an injury needing treatment away from the scene or damage serious enough to require a tow, if the driver receives a moving violation citation within the allowed period.
The deadlines are strict. If alcohol testing does not happen within two hours, the carrier must explain the delay. Testing must stop after eight hours. Drug testing must stop after 32 hours.
The records matter even when no test was completed. A missed test, late test, or written reason for delay may become important evidence in the claim.
Whether the test happened, and whether it happened in time, is evidence either way. A carrier that skipped required testing, or documented a reason for the delay, has created a record that matters long after the toxicology question itself is unanswerable.
What Not to Do in the First Two Weeks
The first two weeks matter. Avoid these mistakes:
- Do not give the trucking company a recorded statement.
- Do not sign a release for your full medical history.
- Do not send the vehicle to salvage before it is inspected.
- Do not post about the crash or your recovery online.
- Do not take a settlement before your future medical needs are known.
Take photos as your injuries change. Keep notes on pain, missed work, and daily limits. Save receipts and write down each witness’s contact details.

Deadlines and Rules That Apply
Most Louisiana injury claims arising on or after July 1, 2024, must be filed within two years under Civil Code article 3493.1. Older claims usually remain under the former one-year rule.
For crashes on or after January 1, 2026, you cannot recover if you are 51% or more at fault. Acts 2025, No. 466 also changed how past medical costs are counted. This makes proof of future treatment more important.
Many interstate trucking companies must carry at least $750,000 in coverage under 49 CFR 387.9. The minimum can rise to $5 million for certain hazardous loads.
Frequently Asked Questions
How Quickly Do I Need to Act?
Act within days when it comes to evidence. You may have two years to file, but video, truck data, and witness details can disappear much sooner.
The Carrier’s Adjuster Seems Helpful. Should I Be Concerned?
The adjuster may be polite, but they work for the trucking company or its insurer. A statement given early may later be used to question fault or your injuries.
Can I File a Claim if I Was Partly at Fault?
Yes, as long as you were not 51% or more at fault. Below that point, your compensation is reduced by your share of fault.
What if an Owner-Operator Owned the Truck?
The motor carrier may still be responsible if the truck was operating under its authority. A broker or shipper may also be involved, depending on the agreement. Our guide on evidence of liability in truck accidents explains how those links are proven.
Conclusion
The first few weeks can shape a Louisiana truck accident claim. Truck data can be lost, testing deadlines can pass, and early statements may be used later. Once that evidence is gone, it is often impossible to replace.
