South Dakota Truck Permits for trip, fuel, oversize & overweight

A truck without South Dakota registration runs on a single-trip permit or a 30-day temporary commercial license permit, and an unlicensed interstate fuel user needs a temporary single-trip fuel permit that expires when the truck leaves. Oversize and overweight permits come from the Highway Patrol Permit Center, and the state sets no weekend or holiday bans. Tell us the truck, load and route, and we file every South Dakota permit the trip needs.

South Dakota and Iowa

How South Dakota permits differ from Iowa's

A load crossing between South Dakota and Iowa changes permit systems at the state line.

  1. A fuel permit that ends at the border

    South Dakota's temporary fuel permit covers one trip and expires when the truck leaves. Iowa's fuel permit covers one trip or 72 hours.

  2. Registration by trip or by month

    South Dakota offers a single-trip or a 30-day registration permit. Iowa sells a 72-hour trip permit that must be bought before entry.

  3. Six inches more height

    South Dakota allows 14 ft without a permit, 15 ft for baled hay. Iowa allows 13 ft 6 in.

  4. Iowa-made goods heading north

    Iowa runs export corridors to South Dakota for goods made in Iowa. Past the line, a load over South Dakota's legal size or weight needs a Highway Patrol permit.

FAQ

South Dakota permit questions

Does a South Dakota temporary fuel permit cover more than one trip?

No. An unlicensed interstate fuel user buys it for one trip into or through South Dakota, and it expires when the vehicle leaves the state.

What is South Dakota's 30-day temporary commercial license permit?

A temporary registration valid 30 days for a truck without South Dakota registration. For one run, the single-trip permit is the other option, and we pick the one that fits your schedule.

Where are South Dakota registration permits sold?

At county treasurers, ports of entry and online. We file them before departure, so the truck does not stop to buy one.

Where are South Dakota's ports of entry?

On I-29 at Sisseton and Jefferson, and on I-90 at Sioux Falls and Tilford.

Will you file South Dakota with every other state on my trip?

Yes. One request with the truck, load and full route is enough; our permit desk files the South Dakota trip, fuel and Highway Patrol permits and the rest of the route, 24/7.
