You can find all the codified state laws by going to
http://legis.state.sd.us/index.aspx plus your current session and legislators. I'd hope all the members would learn to use this site and not be misled by someone who wants to keep folks from learning the laws etc. the following laws are in the draft by the senator to be repealed!
32-20-12. Off-road vehicles--Operation on certain lands as misdemeanor--Registration--Title certificate. No person may operate on a public street or highway an off-road vehicle except for crossing from one side of the road to the other. A person twelve years of age or older may operate an off-road vehicle in a highway ditch if the vehicle is operated as close as possible to the outer edge of the highway right-of-way. However, no person may operate an off-road vehicle in a highway ditch along the interstate highway system, or operate an off-road vehicle on any lands owned, leased, or controlled by the Department of Game, Fish and Parks, or any highway ditch located within, except on a designated off-road vehicle area or designated trail, or operate an off-road vehicle in a highway ditch that is designated as part of the state snowmobile trails system pursuant to chapter 41-19 or a public bike trail. A violation of this section is a Class 2 misdemeanor.
Off-road vehicles need not be registered and licensed for use upon the highways except as provided in § 32-20-13. Off-road vehicles shall be titled. The Department of Revenue shall issue a certificate of title for off-road vehicles the same as for other motor vehicles subject to the provisions of chapter 32-3.
32-20-12.1. Ordinances prohibiting operation of off-road vehicles in ditches--Exceptions--Regulatory signs. Notwithstanding the provisions of § 32-20-12, the Transportation Commission or any board of county commissioners by ordinance may prohibit the operation of off-road vehicles in any highway ditch along any section of highway under its jurisdiction. However, neither the Transportation Commission nor any board of county commissioners may prohibit an off-road vehicle from crossing one side of the highway to the other. This section does not affect off-road vehicles used in normal agricultural operation or service vehicles of any utility while in the line of duty for the utility. For the purposes of this section, the term, utility, means any provider of electric, gas, water, sewer, pipeline, or telecommunications service.
Notice of any restriction made pursuant to this section shall be given by placing and maintaining regulatory signs at each end of the section of highway and at each point of intersection. The signs shall be of substantial construction which conspicuously indicates the restriction.
