Louisiana commercial truck and 18-wheeler accidents are governed by federal FMCSA regulations (49 CFR Parts 350-399) stacked on top of Louisiana law. That means higher insurance minimums ($750K-$1M+), evidence that disappears if you don't act fast (ELD logs, dashcam, driver qualification files), and multiple potential defendants. Federally regulated trucking is its own track. Dudley DeBosier has handled hundreds of Louisiana 18-wheeler cases — free consultation at (866) 271-5909.

Five things separate a Louisiana 18-wheeler case from a passenger-car case: (1) federal FMCSA rules apply on top of Louisiana law, (2) commercial insurance minimums are 10-30x higher than passenger minimums, (3) the evidence set includes ELD logs, driver qualification files, dispatch records, and dashcam that purge on schedule, (4) multiple defendants are usually in play (driver, motor carrier, broker, shipper, vehicle owner), and (5) damages can include catastrophic-injury categories rarely seen in two-car crashes.

49 CFR Parts 350-399 Interstate commercial trucks (over 10,001 lbs gross vehicle weight) are regulated by the Federal Motor Carrier Safety Administration under 49 CFR Parts 350-399. These rules govern almost every aspect of commercial trucking — and a violation is often direct evidence of negligence in a civil claim.
| FMCSA rule | Why it matters in a Louisiana case | |
|---|---|---|
| Hours of service (HOS) | 49 CFR Part 395 — 11-hour driving limit, 14-hour on-duty, 70-hour/8-day cycle | Driver fatigue is the most common provable FMCSA violation. ELD logs prove or disprove compliance. |
| Electronic Logging Devices (ELD) | 49 CFR Part 395 Subpart B | Mandatory since Dec 2019. ELD records HOS automatically. Retention: 6 months by motor carrier. |
| Driver qualification files | 49 CFR Part 391 | Application, MVR, road test, medical certificate. Improper hiring = direct negligence claim against the carrier (negligent hiring/retention). |
| Drug & alcohol testing | 49 CFR Part 382 | Post-accident testing required within 8 hours (alcohol) or 32 hours (drugs) for crashes meeting criteria. Records retained 1-5 years. |
| Vehicle inspection / maintenance | 49 CFR Part 396 — daily DVIRs | Driver Vehicle Inspection Reports retained 90 days. Maintenance records retained for 1 year + ownership period. |
| Cargo securement | 49 CFR Part 393 Subpart I | Improperly secured load that shifts in a crash = often clear-cut liability. |
| Federal minimum | Compare: LA passenger minimum | |
|---|---|---|
| General freight truck (over 10,001 lbs) | $750,000 | $15,000 BI per person / $30,000 per accident / $25,000 PD (R.S. 32:861) |
MCS-90 endorsement Most large carriers carry well above the minimum — primary policy ($1M-$2M) plus excess/umbrella coverage stacking to $10M-$50M. The carrier's MCS-90 endorsement is a federal financial-responsibility guarantee — even if the underlying policy has exclusions, MCS-90 can require the insurer to pay up to the federal minimum.
FMCSA permits motor carriers to purge evidence on a schedule. Without a litigation hold (spoliation) letter, ELD logs, dashcam footage, and DVIRs disappear before discovery begins.
Economic damages Medical bills (past + future) Lost wages + diminished earning capacity Vocational rehabilitation Property damage (vehicle, contents) Out-of-pocket expenses (mileage, prescriptions, equipment)
General damages Past and future pain and suffering Mental anguish Loss of enjoyment of life Disfigurement and scarring Loss of consortium (spouse, parents, children)
Special LA categories Survival action (La. Civ. Code Art. 2315.1) — pre-death pain and suffering Wrongful death (La. Civ. Code Art. 2315.2) — separate claim by survivors Punitive (limited in LA — only in DWI / DUI cases under La. Civ. Code Art. 2315.4 or hazmat-spill cases)
Interstate rear-end by a fatigued or distracted trucker. HOS records + dashcam are the key evidence. Motor carrier + driver both defendants; broker may be in play.
Passenger vehicle goes under (or trailer goes over) — often catastrophic injuries or fatalities. Cargo securement, trailer maintenance, and side-guard rules in play. Survival + wrongful death claims combined.
Higher minimum coverage ($1M+). HMR (Hazardous Materials Regulations) Part 171-180 applies. Spill cleanup, evacuation, and exposure injuries add categories of damages.
Catastrophic crash with multiple-vehicle pile-up. Direct Action against insurer + driver + carrier + broker. Survival action + wrongful death + economic + general damages stacked. Often $10M+ exposure.
