The State Transport Police, part of the Department of Public Safety, are South Carolina's specialized commercial vehicle enforcement agency and work with FMCSA and CVSA. The Department of Education runs the state school bus inspection program.
Yes. S.C. Reg. 38-424 adopts federal Parts 390 to 399 for carriers operating in the state, and S.C. Code 56-5-4240 sets the intrastate line: 26,001 lb using the greater of GVW, GVWR, GCW or GCWR, 16 or more passengers including the driver, or placarded hazmat. There's no separate intrastate trigger for smaller compensated passenger vans.
| Operation | Who's covered |
|---|---|
| Interstate | 10,001 lb or more, plus federal passenger and hazmat triggers (49 CFR 390.5) |
| Intrastate (South Carolina only) | 26,001 lb or more; 16 or more passengers including the driver; placarded hazmat at any weight |
The federal annual, at least every 12 months, for every covered truck, tractor, trailer and bus, with each unit inspected. South Carolina doesn't substitute a state program for it. School buses and private vehicles carrying 10 or more students have their own annual rule.
| Inspection | Applies to | How often | Rule |
|---|---|---|---|
| Federal annual | Every covered CMV and each combination unit | 12 months | 49 CFR 396.17; S.C. Reg. 38-424 |
| School bus inspection | Publicly owned or leased school buses | Annual; never more than 12 months old | S.C. Code 59-67-270 |
| Private student transport inspection | Privately owned vehicles designed and used for 10 or more students | Annual, meeting federal inspection requirements | S.C. Code 59-67-270 |
| Department of Education quarterly inspection | Active route and spare buses in the state maintenance program | Quarterly or every 4,000 miles | State school bus inspection manual |
The federal annual can be done by an inspector qualified under 49 CFR 396.19, including a qualified carrier employee or a commercial garage, fleet leasing company or truck stop with qualified inspectors. That's the model Bright Inspect is designed for.
Public school buses can use the Department of Education program, with district staff trained and certified by the Department, or a federal DOT annual that meets or exceeds the state program. Whether a technology-based inspection is accepted for school buses isn't addressed, so check with your district or the Department of Education, or ask us before booking a school bus.
Keep the annual report 14 months where the vehicle is housed or maintained, with documentation of the current inspection on the vehicle. No state sticker is required for the federal annual. The state school bus program supplies inspection certificate stickers, and private student transport vehicles keep a copy of the inspection report on board at all times.
| Vehicle | Rule |
|---|---|
| Tow trucks | Tow trucks that meet the thresholds follow the federal annual. We're still confirming statewide tow truck rules in South Carolina. Check with the State Transport Police directly. |
| School buses | Annual inspection through the state Education Department program or a qualifying federal annual; State Transport Police can inspect buses at any time |
| Private student transport | Privately owned vehicles designed and used to carry 10 or more students to school, school activities or childcare need an annual inspection meeting federal requirements, with the report kept on board |
State Transport Police officers inspect commercial vehicles at roadside and at scales, around 50,000 to 60,000 inspections a year. 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 South Carolina. Check with the State Transport Police 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.
