South Dakota Ignition Interlock DUI Laws

Information on South Dakota’s DUI and Ignition Interlock Laws

South Dakota laws require that drivers whose blood alcohol concentration (BAC) level of .08 be charged with DUI. However, you can even be charged with DUI with a BAC level of .05 if the arresting officer determines that you could not drive safely.

If you are convicted of DUI in court, you maybe be required to participate in the state’s 24/7 Sobriety program, which submits offenders to testing for alcohol, marijuana, and other controlled substances. As part of the program, you may need to install an ignition interlock device (IID) in your vehicle.

In addition, DUI conviction in South Dakota carries fines, jail terms, and periods of license revocation.

Every situation and state is unique, please consult with your attorney or your state licensing authority to confirm your requirements and obligations.
