DOT inspection requirements in Missouri

The Missouri State Highway Patrol enforces truck and bus safety. Missouri adopts federal rules, covering intrastate property vehicles over 26,000 lb. The federal annual by a qualified inspector is the standard. Missouri's separate state safety inspection at official stations is not an FMCSA-accepted substitute, so some vehicles need both.

Need a DOT inspection near you in Missouri?

For the federal annual you don't need a station. Bright Inspect inspects your truck where it's parked. $99 for one vehicle, with fleet discounts from 2 units. If your vehicle also needs a Missouri state safety inspection, we tell you before you pay.

Who regulates commercial vehicles in Missouri?

The Missouri State Highway Patrol Commercial Vehicle Enforcement Division enforces truck and bus safety. The Patrol's Motor Vehicle Inspection Section licenses official inspection stations and inspectors for the state safety inspection. Other authorized officers can enforce federal motor carrier rules under RSMo 390.201.

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

Yes. Missouri applies the federal rules to intrastate carriers through RSMo 307.400 and 11 CSR 30-6.010. Ordinary intrastate property vehicles are covered over 26,000 lb. That higher line doesn't apply to vehicles carrying 16 or more passengers or placarded hazmat, which are covered at any weight.

OperationWho's covered
Interstate10,001 lb or more, plus federal passenger and hazmat triggers (49 CFR 390.5)
Intrastate (Missouri only)Over 26,000 lb GVWR or GCWR for property vehicles; 16 or more passengers including driver; placarded hazmat at any weight

What annual or periodic inspections does Missouri require?

Covered vehicles need the federal annual every 12 months, with each unit in a combination inspected. Separately, Missouri-registered vehicles that fall under the state safety inspection law need a state inspection at an official inspection station, usually every two years. The two programs are independent: one does not satisfy the other.

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

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

The federal annual can be done by the carrier's qualified inspector or a qualified third party under 49 CFR 396.19. That's the model Bright Inspect is designed for: a federal annual designed to meet FMCSA annual inspection requirements, done where your truck is parked.

The Missouri state safety inspection and the annual school bus inspection must be done by a Missouri-licensed inspector at a Patrol-approved official inspection station, with the vehicle physically presented there. Our federal annual inspection is not a substitute for either, and we confirm which applies before you pay.

What records and stickers does Missouri require?

For the federal annual, keep the report 14 months where the vehicle is housed or maintained, with proof of the most recent inspection on the vehicle. If you use a decal, it must show the inspection date, where the report is kept, the vehicle when needed and that it passed.

The state safety inspection issues a certificate of inspection and approval with a sticker or other approval device.

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

Missouri State Highway Patrol officers and certified commercial vehicle inspectors check trucks at fixed facilities, mobile sites, traffic stops and terminals. 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 roadside inspection doesn't replace the annual.

We're still confirming roadside fines for a missing annual inspection in Missouri. Check with the MSHP Commercial Vehicle Enforcement Division directly.

Missouri DOT inspection FAQs

For the federal annual you don't need a station; a qualified inspector can inspect your truck anywhere, and Bright Inspect does it where your truck is parked. A Missouri state safety inspection, if your vehicle needs one, is done at an official inspection station.

No. Missouri's state inspection isn't an FMCSA-accepted equivalent program, so a vehicle under both rules needs both inspections.

Proportionally registered interstate vehicles are exempt from the state safety inspection, but they still need the federal annual.

Yes, the federal annual. We can't do the Missouri state safety inspection or the school bus station inspection, which require an official Missouri station.
