What to Do in the First 30 Days After a DUI in Montana

Montana Motor Vehicle Division requires SR-22 filing within 30 days of your DUI conviction. Miss that window and your suspension extends automatically until you file and pay a $200 reinstatement fee on top of the original $150 license reissue fee. Your SR-22 filing period starts the day the judge enters your conviction — not the day you get your license back. If you're convicted on March 1st and suspended for six months, your three-year SR-22 clock starts March 1st. File immediately and you serve six months of your SR-22 period while suspended. Wait until reinstatement and you're adding six months to the back end. Most DUI convictions in Montana trigger a six-month suspension for first offense, one year for second offense within five years. You can apply for a restricted probationary license after 30 days on first offense if you install an ignition interlock device, but that probationary license requires active SR-22 on file before MVD approves it.

Standard carriers in Montana — State Farm, Geico, Progressive, Allstate — will file SR-22 for existing customers but typically non-renew at your six-month policy term. New DUI policies route to the non-standard market where monthly premiums run $95–$175 for state minimum liability ($25,000/$50,000/$20,000) with SR-22 endorsement. Non-standard carriers actively writing DUI-SR-22 policies in Montana include Dairyland, The General, Bristol West, and GAINSCO. Not all operate statewide — Dairyland and Bristol West have the widest agent networks in Billings, Missoula, and Great Falls. Direct Auto and Acceptance Insurance write selectively in urban counties only. SR-22 filing itself costs $25–$50 depending on carrier. That's a one-time fee per filing, not annual. Your rate increase comes from the DUI conviction surcharge applied to your base premium, typically 90–140% above your pre-conviction rate for three years. After your SR-22 period ends you can shop back to standard carriers, but the conviction stays ratable for five years in Montana.

Montana allows restricted probationary licenses after 30 days of suspension on first-offense DUI if you install a state-certified ignition interlock device. You must complete the installation before applying — MVD will not issue the probationary license without IID serial number confirmation from your provider. Approved IID providers in Montana: Intoxalock, LifeSafer, Smart Start, and Guardian Interlock. Installation costs $75–$150, monthly monitoring fees run $70–$100, and removal after your restriction period ends costs another $75. Total IID expense for a six-month restriction period runs $650–$900 on top of your insurance and reinstatement costs. Your probationary license restricts you to essential driving: work, DUI education classes, medical appointments, and court-ordered obligations. Violations of your restriction terms — driving outside approved hours, tampering with the IID, failed breath tests — reset your suspension clock to zero and disqualify you from future probationary eligibility.

Montana requires completion of a state-approved Chemical Dependency Education course before license reinstatement on any DUI conviction. The course runs 16 hours minimum for first offense, 40 hours for second offense, and must be completed through a provider certified by the Montana Department of Public Health and Human Services. Course fees range $150–$300 depending on provider and county. Most offer evening and weekend sessions to accommodate work schedules. You can start the course during your suspension period — in fact you should, because MVD will not schedule your reinstatement hearing until you submit your course completion certificate along with your SR-22 filing proof. If your BAC exceeded 0.16 or your case involved injury, property damage, or a minor passenger, the court may order inpatient or outpatient treatment beyond the standard education requirement. Those treatment programs run 30–90 days and cost $1,500–$8,000 depending on intensity. SR-22 filing and license reinstatement cannot proceed until you complete all court-ordered treatment and education.

Montana calculates your three-year SR-22 filing period from the date of conviction. If you were convicted March 15, 2024 your SR-22 obligation ends March 15, 2027 regardless of when you actually filed or when your license was reinstated. This is the most commonly miscalculated deadline. Drivers assume the three years start when they file SR-22 or when they get their license back. File six months late and you lose six months of credit — you're still required to maintain SR-22 until the original three-year mark from conviction. Montana MVD monitors SR-22 compliance electronically. If your carrier cancels your policy or you let coverage lapse even one day during your filing period, MVD receives notification within 24 hours and suspends your license immediately. Reinstatement after an SR-22 lapse requires filing new SR-22, paying a $200 reinstatement fee, and restarting your three-year clock from the lapse date in most cases.

First-year costs for DUI compliance in Montana stack quickly. SR-22 insurance premiums run $1,140–$2,100 annually for state minimum coverage. Add ignition interlock ($650–$900 for six months), DUI education course ($150–$300), license reinstatement fees ($350 total), and court fines ($600–$1,200 on first offense), and you're looking at $2,890–$4,500 minimum. That's before attorney fees if you retained counsel, increased vehicle registration fees if you're required to use special plates, or any treatment costs beyond the standard education requirement. Second-offense DUI costs double in most categories — longer IID periods, higher fines, more intensive treatment requirements. No payment plans exist for SR-22 insurance — you must pay the full six-month premium upfront in most cases. Some non-standard carriers offer monthly payment plans with 15–25% financing charges added. Ignition interlock providers bill monthly. Court fines can sometimes be paid in installments if arranged at sentencing.

Montana requires continuous SR-22 on file for the full three-year period even if you sell your vehicle, move out of state temporarily, or stop driving. Canceling your policy because you're not driving triggers an automatic license suspension and restarts your filing clock. If you don't own a vehicle, you need a named non-owner SR-22 policy. These policies provide liability coverage when you drive borrowed or rental vehicles and satisfy Montana's SR-22 filing requirement. Monthly premiums for non-owner SR-22 run $45–$85 in the non-standard market, roughly half the cost of an owner policy. If you move out of state during your SR-22 period, Montana's requirement follows you. Your new state may have different SR-22 rules or call it by a different name (certificate of financial responsibility in some states), but you must maintain continuous filing and notify Montana MVD of your new address and insurance carrier within 30 days of your move.
