South Dakota Snowmobile Registration and Trail Permit

By Scott Wilder

Short answer: In South Dakota, every snowmobile must be licensed to run on public land, frozen public water, or private land that you do not own. The only exception is a resident riding on property the resident owns. South Dakota does not sell a separate trail pass for standard sleds. The license is the pass.

Residents pay $10 per snowmobile for a one-year license, set in state law (SDCL 32-5-9.1). You buy it at your county treasurer's office. Game, Fish and Parks (GFP) lists the same $10 per year. The fee is prorated monthly. Dealers deliver the paperwork for new sleds they sell.

Nonresidents have two options. A sled that is validly licensed in another state can legally run in South Dakota, per GFP. A sled with no valid license needs a temporary permit: $40, good for five consecutive days. Residents can buy that permit too. GFP says it is sold online and at many trailside vendors.

We checked the GFP page and the state codified law on Oct. 31, 2026. Neither source lists a fee year, so treat these as the current figures as of that date. Rules can change. Confirm before you ride.

How registration works

State law applies the vehicle title, excise tax and registration chapters to snowmobiles. That means a snowmobile is titled and registered much like other motor vehicles (SDCL 32-20A-15).

  • New sled from a licensed dealer: the dealer sends the manufacturer's statement of origin, the fees and taxes, and the forms to the county treasurer where you live.
  • Sled not sold by a licensed dealer: you are responsible for titling and registering it and for paying the fees and taxes.
  • A 3% excise tax applies on the purchase price, less any trade difference, in addition to the $10 license fee (SDCL 32-5-9.3). Not paying the full tax is a Class 2 misdemeanor.
  • The license must be paid before the sled is operated, or before you let anyone else operate it (SDCL 32-5-9.1).

GFP says resident licenses must be permanently affixed to each side of the snowmobile, below the windshield and on the hood cowling.

Resident vs. nonresident

Residents buy the $10 license from the county treasurer. A resident running a sled on property the resident owns is exempt from the licensing requirement. Land owned by someone else is not covered.

Nonresidents do not need a South Dakota license if the sled is validly licensed in another state, per GFP. If it is not licensed, buy the $40 five-day permit. The statute requires the owner of an unlicensed snowmobile to buy it.

The state statute says the temporary permit is for the owner of an unlicensed snowmobile. If you rent, ask the rental operator what is required. We did not verify rental rules.

Where to buy

  • Resident license: county treasurer's office, per GFP.
  • Five-day temporary permit: online through the GFP licensing catalog, linked from the GFP snowmobiling page, and at many trailside vendors, per GFP.

We did not confirm a statewide list of vendors. Check the GFP page for the current link.

Insurance

GFP says snowmobilers who operate in road rights-of-way or on public snowmobile trails must show proof of financial responsibility (liability insurance). GFP also says you must provide that evidence if a law enforcement officer asks, as a secondary action when you are detained for another offense. Carry proof with you.

Rules to know

  • Age. There is no age limit to operate a snowmobile. A person under 14 may not drive across a roadway unless under the immediate direction of a parent, legal guardian, or a person age 18 or older (SDCL 32-20A-3). The GFP snowmobile page we checked lists no required safety course. Take one anyway if you can.
  • Muffler and speed. You need a functioning muffler. You may not ride faster than is reasonable or prudent, or in a reckless way (SDCL 32-20A-2).
  • Interstates. No riding on or across an interstate, except in the ditch of an underpass or on the extreme right of an overpass.
  • Railroads. No riding on railroad right-of-way, except directly across a crossing after stopping and yielding.
  • Ditches. A licensed sled may run in either ditch on state-designated snowmobile trails. In other ditches, stay in the right-hand ditch.
  • Private land. You need permission from the owner or lessee. This does not apply in public road rights-of-way.
  • Alcohol. The operator of a snowmobile is treated as a motor vehicle driver for DUI law (SDCL 32-20A-14).
  • Firearms. Firearms must be unloaded and fully enclosed in a case, with limited exceptions, per GFP.
  • Hunting. You may not chase, drive, harass or kill game from a snowmobile. A narrow coyote exception exists for landowners and lessees.
  • Towns. Cities and towns can set their own snowmobile ordinances.
  • State trail sleds. On a state snowmobile trail, the sled must weigh under 1,400 pounds, run on a track, and steer by skis.
  • Accidents. Report immediately to law enforcement if there is injury or death, or damage over $1,000.

Penalties

Most of the rules above carry a Class 2 misdemeanor. The maximum penalty is 30 days in county jail, a $500 fine, or both (SDCL 22-6-2). Riding an unlicensed sled falls under this.

Where to ride: the Black Hills and beyond

GFP says South Dakota has over 1,500 miles of snowmobile trails, from open prairie in the east to roughly 1 million acres of ponderosa pine in the Black Hills. Trails are open Dec. 15 to March 31. GFP posts trail updates on X for the Black Hills (@SDSnowBHills) and East River (@SDSnowEast).

GFP lists these state parks with snowmobiling: Fisher Grove State Park, Big Sioux Recreation Area, George S. Mickelson Trail, Pelican Lake Recreation Area and Spearfish Canyon Nature Area.

GFP says park rangers patrol the groomed trail system. Trail conditions change fast. Check a current report before you load the trailer.

Motorcycle conversions

A titled motorcycle modified to meet the snowmobile definition needs a separate Motorcycle Snowmobile Trail Pass for state trails. It is $20 and valid Dec. 1 to March 31 (SDCL 32-20A-25, GFP). It is for resident owners and goes on the right side of the unit.

Safety first

A license does not make a trail safe. Check conditions, the forecast and your gear. Stay off ice you have not checked. No ice is ever 100% safe. Check it yourself. Ride with a partner and tell someone your route and return time.
