DOT inspection requirements in Louisiana

Compare Louisiana with other states on the state requirements hub, or see which states run their own inspection programs.

Louisiana State Police Transportation Safety Services handles commercial vehicle enforcement and motor carrier safety. The State Police Motor Vehicle Inspection program, under the Department of Public Safety and Corrections, authorizes the stations and inspectors that issue commercial inspection certificates. The Department of Education sets student transportation rules.

Yes, federal rules are the baseline, with Louisiana's own intrastate thresholds. Ordinary intrastate property vehicles are covered at 26,001 lb GVWR or GCWR or more. Vehicles carrying more than 15 passengers including the driver, and placarded hazmat at any weight, are covered too, and some Part 396 duties reach vehicles from 10,001 lb.

Covered commercial vehicles need an annual inspection through Louisiana's commercial Motor Vehicle Inspection program, which FMCSA accepts in place of the federal annual. Interstate truck tractors, trailers and semitrailers with apportioned plates that are subject to the federal rules are exempt from the state program if they meet 49 CFR 396.17 directly; they can also choose the state certificate (La. R.S. 32:1311).

Every unit counts on its own: see whether each trailer needs its own annual inspection.

Louisiana runs an FMCSA-accepted state program, so vehicles it covers must use it. The state certificate must come from a Louisiana-authorized commercial mechanic inspector at an approved MVI station, with a bay that fits a legal-size tractor-trailer and prescribed equipment. Our federal annual is not a substitute for it.

For apportioned interstate truck tractors, trailers and semitrailers, the federal annual can be done by any inspector qualified under 49 CFR 396.19, which fits Bright Inspect's model. Whether other interstate vehicles, such as straight trucks, can use the direct federal route is still being confirmed, so we check your registration and vehicle before you pay.

Student transportation inspections are done by inspectors approved by the Department of Public Safety and Corrections, and the winter inspection must go through an approved commercial inspection station.

For the state certificate, the inspector completes the Record of Annual Commercial Inspection (DPSSE 1019) for each unit. The carrier keeps it 14 months, the station keeps a copy for 3 years, and the Louisiana commercial inspection certificate is the proof on the vehicle. For the federal annual, keep the report 14 months with proof on the vehicle. Student transportation vehicles get inspection tags or approved alternative documentation.

Louisiana State Police commercial vehicle officers and FMCSA agents conduct roadside inspections at roadside sites, weigh facilities and during targeted operations. Federal rules let an officer cite you under 49 CFR 396.17(c) when proof of a current annual inspection isn't on the vehicle; it carries a CSA severity weight of 4. The officer gives the driver an inspection report. The carrier must certify that listed violations were corrected and return it within 15 days, and keep a copy for 12 months (49 CFR 396.9). Fines are set by state law. A clean roadside inspection doesn't reset your 12-month annual.

We're still confirming roadside fines for a missing annual inspection in Louisiana. Check with Louisiana State Police Transportation Safety Services directly.

Nobody can promise to remove a violation or change a safety score; what fixes the problem going forward is a current inspection and a complete record.
