Montana Ignition Interlock Requirements

Some offenders may be able to regain driving privileges if they install an ignition interlock device (IID) from an approved provider. This guide will explain the interlock process in Montana and how it works.

Requirements

The Montana Ignition Interlock Program

In Montana, the legal limit for drivers is below .08 percent BAC, and anyone found driving at or above the legal limit risks a variety of legal and administrative penalties. These include fines, license suspension, and possible jail time or community service. Montana allows some drivers to regain their driving privileges by installing an ignition interlock device, and requires an IID for repeat DUI offenders.

What Happens if I Get a DUI in Montana?

Montana’s penalties increase if there are aggravating circumstances or prior offenses, but typically DUI offenders will face the following penalties:

First DUI Offense

  • Driver’s license suspended for a minimum of six months
  • May serve at least 24 hours in jail but no more than six months
  • Fines of $1,200 to $2,000
  • Some offenders may have to install an ignition interlock device from an approved provider in order to regain driving privileges
  • A chemical dependency course may be required

Second DUI Offense

  • License suspended for one year
  • Jail term of seven days minimum and one year maximum
  • Fines of $1,200 to $2,000
  • Ignition interlock device may be required to regain driving privileges
  • A chemical dependency course may be required

Third DUI Offense

  • License suspended for one year
  • Jail term of 30 days minimum and one year maximum
  • Fines of $5,000 to $10,000
  • Ignition interlock device may be required to regain driving privileges
  • A chemical dependency course may be required

What Happens if I Refuse to Submit to a DUI Test in Montana?

Montana has an implied consent law, which means refusing the test will result in penalties. They include an automatic driver’s license suspension of one year.

How Do I Regain Driving Privileges in Montana?

Some offenders may be able to get back on the road with an ignition interlock device from an approved provider, like Intoxalock. This will entitle them to a restricted or limited license. To do so, offenders may also have to:

  • Wait the required amount of the suspension period
  • Pay any financial penalties
  • Install an interlock device from an approved provider
  • Pay any application fees
  • Complete a chemical dependency treatment program or class
  • Finish other penalty requirements like community service

The Process: What to Expect

The DUI process may seem complex, but having a clear understanding of each step will help you stay on course.
  1. Consult with Legal Counsel

    Seek guidance from a DUI lawyer to understand your legal options and rights following a DUI violation.

  2. Get an Assessment

    Complete a court-ordered or voluntary assessment to evaluate your risk level and determine any required interventions.

  3. Obtain Proof of SR-22 Insurance, If Required

    If applicable, provide proof of financial responsibility and insurance coverage with an SR-22 certificate.

  4. Schedule Interlock Install

    Speak to our State Specialists to schedule your IID installation to meet court or state requirements.

  5. Regular Monitoring

    Your ignition interlock usage will be regularly monitored to maintain compliance with legal requirements.

  6. Device Removal

    After fulfilling your IID requirement and receiving approval from your monitoring authority, you can arrange to have your ignition interlock device removed at your local service center.

Montana Ignition Interlock Device Cost

Offenders cover the cost of their own ignition interlock device in Montana, and Intoxalock offers flexible payment options. Our devices cost around $100 to install and $2.50 and $3.50 per day to lease. Occasionally, rebates or discounts are available, so be sure to take advantage if you see a deal.
