How quickly must I respond after a DUI arrest?

The most time-critical deadline is the administrative hearing request: 120 days from arrest to request a hearing (under-21 refusal revocation) in South Dakota [§ 32-23-18; 32-23-11]. Missing this deadline waives your right to contest the license suspension, regardless of what happens in the criminal case.

Will I lose my license immediately?

South Dakota imposes an administrative suspension of 1 year revocation of a driver under 21 who refuses chemical analysis, if the secretary of public safety finds the officer complied with the law and the person refused for a first offense [§ 32-23-18; 32-23-11]. A form of restricted driving privileges may be available. This is separate from any criminal license suspension.

What is the difference between the criminal case and the administrative case?

The criminal case is prosecuted in court and can result in jail, fines, and a criminal record. The administrative case is about your driver's license and is handled separately. You can win one and lose the other — they have different standards of proof and different deadlines.

Can DUI charges be reduced?

Outcomes depend on evidentiary strength, procedural compliance by the officer, BAC level, and other factors. An experienced attorney can evaluate whether the evidence supports a motion to suppress, a plea to a lesser charge, or trial.

Does a DUI stay on my record permanently?

South Dakota allows petition for expungement of first DUI offense after completing sentence and a 5-year waiting period with no subsequent convictions. Felony DUI convictions are not eligible. [§ 32-23-1].

Un arresto por DUI genera dos procedimientos separados que corren al mismo tiempo. El caso penal decide culpabilidad, sanciones y su historial. El caso administrativo decide si su licencia queda suspendida — generalmente con un plazo mucho más corto.

Dos vías corren al mismo tiempo: el caso judicial y los plazos administrativos/de licencia. Los plazos, procedimientos y penalidades varían por estado.

The two tracks: criminal and administrative

Track 1: Criminal prosecution

The criminal case is a court proceeding where the state must prove DUI beyond a reasonable doubt. South Dakota's per se BAC limit is 0.08 §32-23-1, but you can also be charged based on impairment regardless of BAC. A first offense is classified as a Class 1 misdemeanor.

Track 2: Administrative license action

The administrative action is handled separately from the criminal case §32-23-18; §32-23-11. It can result in license suspension even if the criminal case is eventually dismissed. You have 120 days from arrest to request a hearing (under-21 refusal revocation) to request a hearing to contest the suspension.

⚠The administrative hearing deadline is short — 120 days from arrest to request a hearing (under-21 refusal revocation). Missing this deadline waives your right to contest the license suspension, regardless of what happens in the criminal case.

What triggers enhanced penalties

Prior DUI within 10 years
Child under 15 in vehicle (aggravated DUI charge)
Serious injury or death

Implied consent and chemical testing §32-23-10

South Dakota has an Implied consent law: by driving on South Dakota roads, you have implicitly consented to chemical testing when lawfully arrested for DUI. Refusing the test carries its own consequences:. In South Dakota, refusal to submit to chemical testing is admissible as evidence at trial §32-23-10.

BAC thresholds that matter

	Category	BAC Limit
Standard per se	0.08 §32-23-1	DUI charge without other evidence of impairment
Enhanced penalty	None §32-23-1	Higher minimum penalties and longer license suspension
Under 21	0.02 §32-23-21	Zero tolerance violation
Commercial (CDL)	0.04 §32-12A-44 §49 C.F.R. § 383.51	CDL disqualification

Why timing matters most

DUI cases are unusually time-sensitive. The administrative hearing deadline begins running from the date of arrest or notice — not from the first court date. Evidence (dashcam footage, witness recollections, calibration records) can deteriorate. Early attorney involvement can preserve options that disappear with delay.

⚠If you have been arrested for DUI in South Dakota, the most time-critical step is requesting the administrative hearing within 120 days from arrest to request a hearing (under-21 refusal revocation). Consult an attorney immediately — this deadline cannot be extended.
