Montana SR22 Insurance Filing Information

Montana SR22 Information & Filings

In the State of Montana, if you are convicted of a DUI (Driving Under the Influence), your license will be suspended for at least 6 months.

In order to get your Montana driver’s license back, you will need to:

 purchase Montana SR22 insurance.
 pay the reinstatement fee.
 complete an alcohol treatment program.
 (possibly) install an ignition interlock device.
 (possibly) take a driver examination.

Montana’s Ignition Interlock Program:

A breath alcohol ignition interlock device (BAIID or IID) is a small computerized device that attaches to your ignition. In order to start your vehicle, you will need to blow into the device for 4-5 seconds. If your breath sample demonstrates that you have not been drinking, then the vehicle will start. Once the vehicle starts, the IID will ask for a “rolling retest” periodically.

If you have been convicted of a first offense DUI with a blood alcohol concentration (BAC) of 0.16 or greater, or if you have been convicted of a subsequent DUI, you will need to install an ignition interlock device in the vehicle(s) you drive.

Currently, the following vendors are approved to install and service ignition interlock devices in Montana:

• Big Sky Ignition Interlock (406) 599-5362
• Consumer Safety Technology, Inc. (877) 777-5020
• DMB Interlock & Safety Services, Inc. (406) 698-7297
• Mountain Peaks, Inc. (866) 453-6784
• Smart Start, Inc. (800) 880-3394

The person convicted of the DUI is responsible for all the IID fees. For example, one Montana vendor charges $85 for installation, and then $2.50 a day after that. This vendor also asks for a $35 deposit at the time of installation. There may also be additional recalibration and removal fees.
