The Oklahoma Department of Public Safety enforces motor carrier safety through Highway Patrol Troop S, which handles commercial motor vehicle enforcement. The State Department of Education's Office of Pupil Transportation oversees school bus inspections.
Yes. Oklahoma adopts federal Parts 390 to 397 and applies Part 396 to intrastate carriers through OAC 595:35-1-5. Coverage starts at 10,001 lb using the greater of GVWR, GVW, GCWR or GCW, with federal passenger and placarded hazmat triggers. Qualifying farm and pipeline exemptions may apply.
| Operation | Who's covered |
|---|---|
| Interstate | 10,001 lb or more, plus federal passenger and hazmat triggers (49 CFR 390.5) |
| Intrastate (Oklahoma only) | 10,001 lb or more; more than 8 passengers for compensation; more than 15 passengers not for compensation; placarded hazmat at any weight |
The federal annual covers every covered truck, tractor, trailer, bus and converter dolly at least every 12 months, with each unit inspected separately. Oklahoma doesn't run a separate state program that replaces it. Public school buses need their own annual mechanical inspection.
| Inspection | Applies to | How often | Rule |
|---|---|---|---|
| Federal annual | Every covered CMV and each combination unit | 12 months | 49 CFR 396.17, Appendix A; OAC 595:35 |
| School bus mechanical inspection | Each bus operated by an Oklahoma public school district | Annual | OAC 210:30-5-6; Oklahoma School Bus Inspection Guide |
The federal annual can be done by an inspector qualified under 49 CFR 396.19, a qualified carrier employee or a qualified third party; it doesn't have to be the Highway Patrol. That's the model Bright Inspect is designed for.
School bus inspections need an inspector approved by the State Department of Education, with an inspector number. One route to approval is federal 396.19 qualification plus 396.25 brake qualification. Whether a technology-based inspection is accepted for school buses is still being confirmed, so check with the Office of Pupil Transportation or ask us before booking a school bus.
Keep the annual report 14 months where the vehicle is housed or maintained, with proof of the current inspection on the vehicle. No state sticker is required for the annual. School districts keep the official Annual School Bus Inspection Report on file for 5 years, according to the current state form.
| Vehicle | Rule |

| Tow trucks | Tow trucks at 10,001 lb or more follow the federal annual. We're still confirming statewide tow truck rules in Oklahoma. Check with OHP Troop S directly. |
| School buses | Annual mechanical inspection by an approved inspector using the state's 65-item report, plus a daily pre-trip inspection with a written report kept 90 days and a post-trip check for children left on board |
| Passenger carriers | Covered intrastate at more than 8 passengers for compensation or more than 15 not for compensation. We're still confirming other Oklahoma passenger carrier rules. Check with OHP Troop S directly. |
Troop S troopers in the Commercial Vehicle Traffic Enforcement Program, certified to the North American Standard Level I, inspect commercial vehicles chosen through random selection (Oklahoma roadside inspection program). 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.
Oklahoma DPS states that a Level I roadside inspection with no violations can serve as the vehicle's required annual. Keep that report with your records, and confirm with Troop S before relying on it.
We're still confirming roadside fines for a missing annual inspection in Oklahoma. Check with OHP Troop S directly.
Stopped without proof of a current annual? See what to do when your inspection expired or failed at roadside and what happens if your annual inspection is expired. 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.
