Hauling only inside South Dakota

South Dakota lists vehicle registration and proof of insurance as the credentials every operator needs. Operating authority, UCR and IFTA appear only on its list for interstate carriers.[1] We found no separate state operating authority for intrastate general freight: the state’s old motor carrier permit sections have been repealed.[2] Intrastate trucks register at the county treasurer.[3]

South Dakota doesn’t generally require a USDOT number for trucks that stay in state. It isn’t on FMCSA’s list of states that do, and the state ties the requirement to crossing state lines at more than 10,000 lb.[4][5] Hazmat carriers that need a federal hazmat safety permit are the exception. If you’re unsure, call Highway Patrol Motor Carrier Services at 605-224-7364.

Federal safety rules still apply to intrastate trucks of 26,001 lb and up, placarded hazmat loads and vehicles carrying more than 15 passengers. Intrastate drivers may be 18.[6]

Insurance South Dakota expects to see

  • Insurance card in the truck. Drivers carry the South Dakota evidence of insurance card, showing the VIN or “Fleet Insured.”[7]
  • State minimum. $25,000/$50,000/$25,000 applies to every vehicle.[8]
  • Federal limits. South Dakota adopts the federal motor carrier rules, including the federal insurance rules in 49 CFR Part 387, and says its references to interstate operations include intrastate.[6] For for-hire general freight, plan on at least the federal $750,000 minimum[9], and confirm your situation with Motor Carrier Services.
  • No state filing found. We found no South Dakota requirement for a state insurance filing such as a Form E.

Brokers and shippers usually ask for more than the minimum, commonly $1,000,000 in auto liability plus a cargo limit.

Rules that change how you run in South Dakota

  • Spring load limits. Certain highways carry frost restrictions from February 15 to April 30, and only limited overweight permits are issued then.[10]
  • Sturgis Rally. Large loads face restrictions in five Black Hills counties in early August.[10]
  • Black Hills tunnels. SD 87 and US 16A are not through routes for commercial traffic.[10]
  • Ports of entry. Every vehicle over 10,000 lb must stop.[5]
  • New since July 1, 2026. Intrastate CDL holders are no longer exempt from the federal physical qualification rule, non-CDL drivers of combinations over 26,001 lb must carry a medical card, and the two-axle intrastate exemption is gone.[5]
  • Contracts. South Dakota voids contract clauses that make a motor carrier cover a shipper’s own negligence.[2]

Permits, taxes and South Dakota freight

IRP plates, IFTA, UCR and trip permits go through the Department of Revenue’s Motor Carrier Services in Pierre (605-773-3541).[11] Oversize and overweight permits, including harvest and baled-feed permits and loads over 80,000 lb on the Interstate, go through Highway Patrol Motor Carrier Services online or at 605-224-SEMI.[12] South Dakota has no weight-distance tax.

I-90 and I-29 meet at Sioux Falls[13], and nearly 2,000 miles of rail, including BNSF and short lines, feed the elevators.[14] Agriculture drives the freight: a 2021 state study put agriculture and related industries at $32.1 billion in output, led by cattle, corn, soybeans, hogs and dairy, with about 16 ethanol plants in the state.[15]

What to have ready for a South Dakota quote

  • USDOT and MC numbers, if you have them
  • Where the trucks are garaged, your usual routes and your radius
  • What you haul: grain, livestock, ethanol, equipment or general freight
  • Driver names, license numbers and years of experience
  • Year, make, VIN and value of each truck and trailer
  • Current policy and loss runs, if you have been insured before
  • Any insurance requirements from your brokers, shippers or lease

Frequently asked questions

Do I need state authority to haul for hire within South Dakota?

We found no separate state operating authority for intrastate general freight. South Dakota requires registration and proof of insurance from all operators; operating authority, UCR and IFTA apply to interstate carriers.[1][2]

Do I need a USDOT number for intrastate trucking in South Dakota?

Generally no. South Dakota is not on FMCSA’s list of states that require one, and state guidance ties the number to crossing state lines. Hazmat carriers that need a federal permit are the exception; confirm at 605-224-7364.[4][5]

Does South Dakota require a Form E?

We found no state filing requirement. Carry the South Dakota insurance card. Because the state adopts the federal insurance rules, plan on at least $750,000 for for-hire general freight.[7][6]

When are South Dakota’s spring load limits?

From February 15 to April 30 on certain highways, with limited overweight permits during that period.[10]

Where do I get an oversize or overweight permit in South Dakota?

From South Dakota Highway Patrol Motor Carrier Services, online through the state permitting system or by phone at 605-224-SEMI.[12]
