South Dakota’s Ignition Interlock Device Laws

South-Dakota-FlagIn the State of South Dakota, drivers convicted of driving under the influence (DUI) will have to participate in the State’s 24/7 Sobriety Program. Participation in the Program may include the installation of an ignition interlock device (IID). If ordered to install an IID, the device must be installed in each of the participant’s vehicles and the individual is responsible for all costs associated with it. All IIDs must be obtained from IID vendors who have been approved by South Dakota’s Attorney General. Within twenty-four (24) hours of installing an IID, both the vehicle and necessary documentation must be presented to the agency overlooking the Program.

Rolling re-tests are standard in IIDs approved by the State of South Dakota. For every breath submission, a photograph of the individual is taken and all data is saved in the device. This information is electronically submitted daily. When the IID is installed by the approved vendor, a maintenance program will be explained to the offender and the individual is responsible for servicing the device at those times. Every ninety (90) days, the individual must submit all IID service documentation to the appropriate agency.

DUI convictions in the State of South Dakota result in driver’s license revocation for:

  • One (1) year maximum for 1st offense
  • One (1) year minimum for 2nd and 3rd offenses
  • Two (2) year minimum for 4th offense
