DOT inspection requirements in Mississippi

The Mississippi Department of Public Safety's Commercial Transportation Enforcement Division enforces truck and bus safety. Mississippi broadly adopts federal rules, starting at 10,001 lb. There's no state inspection station program replacing the federal annual, so a qualified inspector's annual is the standard. School buses also need quarterly inspections.

Who regulates commercial vehicles in Mississippi?

The Mississippi DPS Commercial Transportation Enforcement Division and the Mississippi Highway Patrol Motor Carrier Safety Division enforce truck and bus safety and run roadside inspections. The Mississippi Department of Education oversees school bus inspections.

Does Mississippi follow federal rules, and what are the intrastate thresholds?

Yes. Mississippi enforces the federal motor carrier safety rules for intrastate carriers, subject to state exemptions. Coverage starts at 10,001 lb using the greater of GVWR, GVW, GCWR or GCW; passenger vehicles and placarded hazmat are covered too (Mississippi DPS commercial vehicle FAQ).

What annual or periodic inspections does Mississippi require?

The federal annual, at least every 12 months, for every covered power unit, bus, truck, trailer, semitrailer, full trailer and converter dolly. In a combination, every unit has to pass on its own. Mississippi doesn't run a state inspection station program that replaces it.

Who can perform the inspection, and is a technology-based inspection accepted?

The federal annual can be done by anyone qualified under 49 CFR 396.19, and the carrier keeps proof of that inspector's qualifications. That's the model Bright Inspect is designed for: a federal annual designed to meet FMCSA annual inspection requirements, done where your vehicle is parked.

Quarterly school bus inspections are written for trained school system inspectors, technicians and transportation staff. Mississippi's rules don't clearly allow an independent third-party or remote inspector, so check with the Mississippi Department of Education Pupil Transportation office or your district before using our inspection for that purpose.

What records and stickers does Mississippi require?

Keep the annual report 14 months, with the report or other permitted proof on the vehicle. No state sticker is required for the annual. Quarterly school bus inspections are recorded on the Mississippi School Bus Inspection Form; no sticker applies to that program either.

What happens if your inspection is expired at a roadside stop in Mississippi?

Trained officers from DPS Commercial Transportation Enforcement and MHP Motor Carrier Safety, along with FMCSA personnel, conduct roadside inspections. They can check annual inspection proof along with credentials, permits and weight. 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 replace the annual.

We're still confirming roadside fines for a missing annual inspection in Mississippi. Check with the Mississippi DPS Commercial Transportation Enforcement Division 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.
