Ignition Interlock and 24/7 Sobriety
MCA 61-8-1010 — a choice of monitoring on a first DUI, and on a second, the program, the interlock, or the cars seized
On a first DUI conviction, if a probationary license is recommended, the court may require the 24/7 sobriety and drug monitoring program or an interlock as a condition.
Who handles this in Montana: State Bar of Montana, Licensed Lawyer Montana; and legal aid programs and the state offices, listed in the Montana directory.
- On a second or later conviction, the court orders the 24/7 sobriety and drug monitoring program or a court approved testing program, at the person's cost.
- Or, with a probationary license, restricts the person to a vehicle with a working ignition interlock, paid for by the person.
- Or orders every vehicle the person owned at the time of the offense seized and forfeited.
A common carrier's vehicle, or one taken unlawfully from its owner, is not forfeited for the driver's act, and a lender's security interest survives where the lender could not have known.
