South Dakota DUI & Ignition Interlock (2026): What the Law Actually Requires
South Dakota has no all-offender IID mandate — the 24/7 Sobriety Program is the primary sanction. South Dakota does not require an ignition interlock for every DUI. No section of SDCL ch. 32-23 mandates an IID for any DUI conviction. Instead, the state uses the SD Attorney General’s 24/7 Sobriety Program as the primary compliance mechanism. An IID may be required as one option within the 24/7 program framework, or as a court-ordered permit condition — but this depends on your specific case. Read your sentencing paperwork and confirm with your attorney what your conditions are.
If you found this page searching for “South Dakota ignition interlock requirements,” the honest answer is: an IID may apply to you — or it may not. South Dakota’s 24/7 Sobriety Program is the state’s main DUI sanction. An IID is one possible component within that program, not an automatic mandate. Your court and permit conditions determine what applies.
South Dakota DUI / 24/7 Program at a glance
| Offense term | DUI (Driving Under the Influence) — SDCL 32-23-1 |

The 24/7 Sobriety Program — South Dakota’s primary DUI sanction
South Dakota’s 24/7 Sobriety Program (SDCL 1-11-17 to 1-11-33), administered by the SD Attorney General, is required for court permits when a driver has a prior DUI conviction within 10 years or had a BAC of 0.17%+ (SDCL 32-23-23). Participation options typically include:
- Twice-daily breath testing: Report to a testing site morning and evening. Statutory fee cap: not more than $3/day.
- SCRAM continuous monitoring: Wrist bracelet monitors alcohol continuously.
- IID (ignition interlock): In-vehicle device as an alternative monitoring method within the 24/7 framework. Statutory fee caps: $40 enrollment, $20 per inspection interval, $1/day device use per DPS agreement.
The court and the 24/7 program administrator determine which monitoring option applies to your case. Not all 24/7 participants use an IID — some use daily breath testing or SCRAM instead. Your participation agreement and court permit specify your conditions.
