For first-time offenders and repeat DUI offenders, your license will be confiscated immediately per Montana’s Administrative License Revocation (ALR) if:
- Your blood alcohol concentration (BAC) level was .08 or higher
- You refused a breath test
Courts in Montana require second-time offenders to install and maintain Ignition Interlock Devices (IID) on their vehicles. You’re required to pay for all costs associated with the IID, from installation, monthly lease payments, and service fees to removal.
