The Ignition Interlock
IC 9-30-6-8 — driving without the required interlock is a Class B infraction, and a Class B misdemeanor knowingly
On probable cause of a per se alcohol offense, a court may, instead of a suspension, order that the person drive only a vehicle with a functioning registered ignition interlock device. The order lasts until the court tells the bureau the charges are resolved.
Who handles this in Indiana: legal aid programs and the state offices, listed in the Indiana directory.

Where a court orders an interlock on a vehicle the restricted person owns or expects to drive, it sets how long the device stays, never longer than the maximum prison term it could have imposed. The person pays for installation unless the court finds the person indigent.
Time with an interlock installed, under the court's order or as a condition of specialized driving privileges, is credited against the suspension.
