“MVD must remove the IID requirement for a person only convicted of DUI for having a drug or its metabolite in the person’s body if the individual completes alcohol or drug screening and the court determines no alcohol education or treatment is required. Additionally before September 2013, MVD was allowed to permit certain individuals to be placed in a continuous alcohol monitoring (ankle bracelet etc.) program instead of installing an IID. However due to a federal requirement MVD’s ability to do so was eliminated and the person must install an Ignition Interlock Device.
MVD must defer the six months of the twelve month IID for a first time, non-extreme DUI offender if the person completes certain requirements, including alcohol education of at least 16 hours and maintaining a functioning IID consistent with statutory requirements. In order to to eligible for the six month deferral, the person must not have attempted to operate a vehicle with an alcohol concentration of .08 or higher two or more times during the license restriction or have been involved in a motor vehicle accident that resulted in physical injury or property damage at the time of the DUI offense. The deferral is revoked, however, if the person is arrested for a DUI offense during the period of deferral.”*
