South Dakota Has No Stop and Identify Statute, but Refusing to Name Yourself for a Petty Offense Summons Is a Crime

Take the three situations separately, because South Dakota treats them differently and the difference is where the practical answer lives.

First, a bare street detention. Search South Dakota's crimes title for a duty to identify and there is nothing: no provision requiring a person to give a true name and address, no loitering statute conditioned on failing to explain oneself, and no general failure-to-identify offense. SDCL 22-11-6, the obstruction section, punishes only a person who by using or threatening to use violence, force, or physical interference or obstacle intentionally obstructs, impairs, or hinders the enforcement of the criminal laws or the preservation of the peace by a law enforcement officer acting under color of authority. Silence is none of those things. The resisting arrest offense at SDCL 22-11-4 is drawn just as physically, reaching a person who prevents or attempts to prevent an arrest by using or threatening physical force or violence, or by any other means creating a substantial risk of physical injury. So on the words of the statutes, a South Dakota resident who declines to identify during a detention commits no offense.

Second, and this is where South Dakota differs from the states usually grouped with it, there is a real criminal identification duty in one defined setting. SDCL 23-1A-9 provides that any person who resists the service of a petty offense complaint and summons, or who refuses to give a law enforcement officer the information necessary to complete a petty offense summons and complaint, is guilty of a Class 2 misdemeanor. Petty offenses in South Dakota are the everyday traffic and equipment violations of Title 32, so this duty is not obscure. The trigger is narrow and worth holding on to: the officer must actually be issuing a petty offense complaint and summons, not merely investigating. Once that is happening, refusing to supply the details the form requires converts a twenty-five dollar civil matter into a criminal charge carrying up to thirty days in county jail.

Third, drivers. SDCL 32-12-39 requires each licensee to have a driver license in the licensee's immediate possession at all times when operating a motor vehicle, and to display the driver license upon demand of a judge of a court of record, a magistrate, a peace officer, or a field deputy or inspector of the Department of Public Safety. The section names four categories of demanding official rather than granting a general power, and a violation is a petty offense, not a crime. A passenger is not a licensee operating a motor vehicle and is outside the section entirely.

Lying is the one thing that carries serious exposure regardless of setting. SDCL 22-40-1 provides that no person may impersonate any other person, which includes offering a fictitious name or false date of birth, with intent to deceive a law enforcement officer, and makes a violation a Class 1 misdemeanor. That is the heaviest misdemeanor grade South Dakota has, up to one year in county jail and a two thousand dollar fine under SDCL 22-6-2, and it is four times the exposure of refusing to answer under 23-1A-9. The 2006 amendment that inserted the fictitious-name and false-date-of-birth language, SL 2006, ch 129, is what makes the section reach a false name rather than only an assumed uniform or badge. SDCL 22-11-9 separately makes it a Class 1 misdemeanor to make a report to law enforcement authorities of a crime or incident within their official concern knowing it did not occur, or furnishing information relating to an offense knowing that information is false.

The practical shape, then, is: you may decline to answer, but you may not lie, and once a citation book is out you have to supply what the citation needs. That combination is unusual. It gives South Dakota a genuine criminal backstop, but only after the officer has committed to writing a ticket rather than at the investigative stage where most identification disputes actually happen.

Refusing to give the information necessary to complete a petty offense summons, or resisting its service, is a Class 2 misdemeanor under SDCL 23-1A-9, which SDCL 22-6-2 sets at up to thirty days imprisonment in a county jail or a five hundred dollar fine, or both. Offering a fictitious name or false date of birth with intent to deceive an officer is a Class 1 misdemeanor under SDCL 22-40-1, punishable by up to one year in a county jail or a two thousand dollar fine, or both.

Failing to have or display a driver license under SDCL 32-12-39 is a petty offense, which SDCL 22-6-7 makes a civil action in which the state is the plaintiff, disposed of under chapter 23-1A with a twenty-five dollar judgment under SDCL 23-1A-22. A driver who signs a written promise to appear under SDCL 23-1A-11 and then intentionally breaks it commits a Class 2 misdemeanor. Refusing to identify during a detention that has not reached the citation stage is not itself chargeable, since neither SDCL 22-11-6 nor SDCL 22-11-4 reaches conduct without force, threat, physical interference or an obstacle.

SDCL 22-11-5 removes the defence that an arrest was unlawful where the officer was acting under color of authority and used reasonable force, so the place to litigate the stop is in court, not at the roadside.
