Arrested for DUI in South Dakota? Two Clocks Started the Moment You Were Stopped

A DUI in South Dakota is not one case — it's two. There's the criminal charge in Circuit or Magistrate Court, and there's a separate fight over your driver's license that runs on its own short deadline. Most people only worry about the court date and let the license clock run out without knowing it existed. Don't. Call 1-844-690-0555 right now — free, 24/7 — and a legal assistant trained on South Dakota and federal law will walk you through both tracks in plain English. It's legal information, not legal advice, and the call creates no attorney-client relationship.

DUI Defense in South Dakota — what to do right now

First, write down the date you were arrested — both your deadlines count from it. If a chemical test was refused or your BAC was over the limit, the state can move to revoke your license, and you generally have to request an administrative hearing within 120 days of the arrest or the revocation just happens. Do not assume your court date covers the license side; it usually doesn't. Don't post anything about the arrest online, don't talk to the prosecutor without advice, and get your case understood today. Call 1-844-690-0555 — free, 24/7 — and we'll map exactly which deadline is closest and what to do before it passes.


The law in South Dakota: DUI Defense

South Dakota calls it DUI, and the controlling law is South Dakota Codified Laws (SDCL) chapter 32-23. Under SDCL 32-23-1 it is illegal to drive with a blood alcohol concentration of 0.08 or more, or while under the influence of alcohol, a drug, or any combination — regardless of your exact number. The limit drops to 0.04 for commercial drivers and, for anyone under 21, SDCL 32-23-21 sets a near-zero-tolerance standard of 0.02. A BAC of 0.17 or higher triggers a mandatory court-ordered chemical dependency evaluation.

A first or second DUI is a Class 1 misdemeanor and is typically handled in Magistrate Court, while a third or subsequent DUI is a felony heard in Circuit Court — South Dakota has seven judicial circuits with elected judges. Appeals go only to the South Dakota Supreme Court in Pierre. The criminal case decides guilt and the jail/fine/probation outcome. It does not, by itself, resolve what happens to your license.

Penalties climb fast with priors, but only recent ones count: under SDCL 32-23-4.1, a prior DUI more than ten years before the current offense generally can't be used to bump you up to a second or subsequent charge. First offense (SDCL 32-23-2) and second offense (SDCL 32-23-3) are both Class 1 misdemeanors carrying up to one year in county jail and a $2,000 fine; a third offense (SDCL 32-23-4) is a Class 6 felony carrying up to two years in the state penitentiary and a $4,000 fine.

By driving here you've already 'consented' to chemical testing under South Dakota's implied-consent law (SDCL 32-23-10). Refuse the test and the Department of Public Safety can revoke your license for one year, separate from anything the court does (SDCL 32-23-11). To contest a refusal revocation you generally must request an administrative hearing within 120 days of your arrest. This is the deadline that blindsides people, because it runs whether or not you've even been to court yet. Call 1-844-690-0555 and we'll explain both tracks — legal information, not legal advice.

South Dakota Invented the 24/7 Sobriety Program — and You'll Meet It

South Dakota didn't just adopt 24/7 Sobriety — it created it, a 2005 pilot born out of the Attorney General's office under SDCL 1-11-14 and since copied across the country. If you're facing a second-or-subsequent DUI here, a court can order twice-daily breath tests at a local sheriff's office, or a continuous-alcohol-monitoring ankle bracelet, as a condition of bond or probation — and a work permit after a second offense is conditioned on you taking part. Miss or fail a test and the sanction is swift and certain: often a night or two in jail, no long hearing. It's strict, it's local, and most people have never heard of it until they're in it. Call 1-844-690-0555 and we'll explain in plain English how the program works and what your DUI exposure looks like. Legal information, not legal advice.


Likely outcomes & penalties

Every case turns on your record, your BAC, and the circuit you're in — but here's the realistic range South Dakota law sets. These are outcomes, not promises, and nothing here is legal advice.
First offense
Class 1 misdemeanor: up to 1 year county jail and/or a $2,000 fine, plus a minimum 30-day license revocation. A work permit may be possible, often conditioned on 24/7 testing — especially if BAC was 0.17+.
Second offense (within 10 yrs)
Class 1 misdemeanor: up to 1 year jail and/or $2,000, plus a minimum one-year unconditional license revocation and mandatory participation in the 24/7 Sobriety Program.
Third offense
Class 6 felony: up to 2 years in the state penitentiary and/or a $4,000 fine, a minimum one-year revocation, and likely chemical dependency evaluation and 24/7 monitoring.
Test refusal
A separate one-year license revocation through the Department of Public Safety under the implied-consent law — even if the DUI charge itself is later reduced or dismissed. The 120-day hearing window is how you fight it.

Mistakes to avoid

⚠️
Treating the case as one problem. The criminal charge and the license revocation are two separate tracks with two separate deadlines — winning one doesn't fix the other.
⚠️
Letting the ~120-day administrative hearing window lapse. If you don't request the hearing in time, the refusal revocation takes effect with no fight at all.
⚠️
Assuming a refusal is the safe move. In South Dakota refusing the chemical test triggers its own one-year revocation under implied consent, on top of whatever the DUI does.
⚠️
Underestimating the 24/7 Sobriety Program. Missing a single twice-daily breath test or failing a CAM-bracelet reading can land you in jail fast, with no lengthy hearing.
⚠️
Forgetting the 10-year lookback. People plead to a 'first' offense not realizing a DUI from within the last decade can make this a second or felony-level charge.

FAQ — DUI Defense in South Dakota

Is it called DUI or DWI in South Dakota?

South Dakota uses 'DUI' — driving under the influence — under SDCL chapter 32-23. You'll hear 'DWI' from out-of-state friends, but the charge and the paperwork here say DUI. For exactly how it applies to your stop, call 1-844-690-0555 — free, 24/7, legal information, not legal advice.

What is the legal BAC limit in South Dakota?

It's 0.08 for most drivers under SDCL 32-23-1, 0.04 for commercial drivers, and just 0.02 for anyone under 21 under SDCL 32-23-21. But you can be convicted under the limit if you're 'under the influence.' Call 1-844-690-0555 and we'll explain how your number fits your case.

I refused the breath test — what happens to my license now?

Refusing triggers a separate one-year license revocation through the Department of Public Safety under South Dakota's implied-consent law (SDCL 32-23-10 and 32-23-11), independent of the DUI charge. To fight it you generally have to request an administrative hearing within 120 days of your arrest. Call 1-844-690-0555 today so you don't miss that window.

How long do I have to act on the license side?

The administrative deadline is short — generally about 120 days from your arrest date to request a hearing on a refusal revocation, and it runs whether or not you've been to court. That's why we tell people to write the arrest date down first. Call 1-844-690-0555 — free, 24/7 — and we'll pin down which deadline is closest for you.

Will a first DUI put me in jail?

A first offense is a Class 1 misdemeanor (SDCL 32-23-2) that allows up to one year in county jail and a $2,000 fine, but many first offenses resolve with probation, fines and a license revocation rather than significant jail. Outcomes vary by circuit and BAC. Call 1-844-690-0555 to understand your realistic range — information, not advice.

What is the 24/7 Sobriety Program and will I be on it?

It's South Dakota's own invention (SDCL 1-11-14): twice-daily breath tests at a sheriff's office or a continuous-alcohol-monitoring ankle bracelet, run by the Attorney General's office. It's common after a second-or-subsequent DUI and is often a condition of a work permit. Miss or fail a test and jail can follow fast. Call 1-844-690-0555 and we'll explain how it would apply to you.

Can I still drive while my case is going on?

Sometimes. South Dakota allows limited driving privileges or a work permit in many cases, but after a second offense that permit is typically conditioned on joining the 24/7 Sobriety Program, and you may need proof of financial responsibility (SR-22). Call 1-844-690-0555 and we'll walk through whether a permit is realistic in your situation.

Does an old DUI from years ago still count against me?

Only if it's recent enough. Under SDCL 32-23-4.1, a prior DUI more than ten years before your current offense generally can't be used to escalate this one to a second or felony charge. The ten-year lookback matters a lot. Call 1-844-690-0555 and we'll help you understand how your record is counted.

When does a DUI become a felony in South Dakota?

A third DUI within the lookback period is a Class 6 felony under SDCL 32-23-4, carrying up to two years in the state penitentiary and a $4,000 fine, and it's heard in Circuit Court rather than Magistrate Court. Fourth and subsequent offenses escalate further. Call 1-844-690-0555 to understand which level your charge sits at.

Do you cover the whole state, including the reservations and the Black Hills?

Yes. The call line covers all of South Dakota — Sioux Falls and the east, Rapid City, Spearfish and Sturgis in the west, Pierre, Aberdeen, Yankton and everywhere between. Call 1-844-690-0555 anytime, 24/7, from anywhere in the state.
