DOT inspection requirements in South Dakota

The South Dakota Highway Patrol enforces truck and bus safety. South Dakota adopts federal rules, covering intrastate trucks at 26,001 lb, more than 15 passengers, or placarded hazmat. There's no state program replacing the federal annual, so a qualified inspector's annual is the standard. School buses and nonprofit buses seating 16 or more need a separate state inspection.

Who regulates commercial vehicles in South Dakota?

The South Dakota Highway Patrol, part of the Department of Public Safety, enforces motor carrier safety statewide through its Motor Carrier district. The Highway Patrol also approves inspectors for school buses and nonprofit passenger vehicles.

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

Yes. South Dakota adopts federal Part 396 for intrastate carriers under SDCL 49-28A-3, with its own scope. Ordinary intrastate property vehicles are covered at 26,001 lb using the greater of GVWR, GVW, GCWR or GCW; vehicles carrying more than 15 passengers and placarded hazmat are also covered.

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 an inspector qualified under 49 CFR 396.19, a qualified carrier employee or a qualified third party. That's the model Bright Inspect is designed for.

School bus and nonprofit passenger vehicle inspections need an inspector approved by the Highway Patrol, which sets its own standards; federal 396.19 qualification alone may not be enough. Whether a technology-based inspection is accepted hasn't been confirmed, so check with the Highway Patrol or ask us before booking one of these vehicles.

What records and stickers does South Dakota require?

Keep the annual report 14 months, with evidence of the most recent inspection on the vehicle. No state sticker is required for the federal annual. School buses display the Highway Patrol inspection certificate above the windshield, and nonprofit passenger vehicles display their Highway Patrol certificate on the vehicle.

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

Highway Patrol officers inspect vehicles in operation and can place an unsafe vehicle out of service. State law also lets the Department of Public Safety inspect carrier records and premises (SDCL 49-28A-6). 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.

South Dakota DOT inspection FAQs

You don't need a station. South Dakota uses the federal annual model, so a qualified inspector can inspect your truck anywhere. Bright Inspect does it where your truck is parked.

If it seats 16 or more, including the driver, and a nonprofit uses it to carry its members, yes. It needs an inspection by a Highway Patrol-approved inspector before October 1 each year, with the certificate displayed.

Not automatically. It's a separate state program, so a bus that also falls under federal rules may still need its federal annual.
