Minimum Coverage Requirements in Montana
Montana requires minimum liability coverage of 25/50/20: $25,000 per person for bodily injury, $50,000 per accident for bodily injury, and $20,000 for property damage. Drivers with DUI convictions, suspended licenses due to excessive points, uninsured accidents, or multiple at-fault violations typically face SR-22 filing requirements. The Montana Motor Vehicle Division tracks SR-22 compliance electronically, and any lapse triggers immediate license suspension. Once your SR-22 period ends, you can transition back to standard carriers, though your violation remains on your driving record for 3–5 years depending on severity.
How Much Does Car Insurance Cost in Montana?
High-risk insurance rates in Montana vary significantly by violation type, location, and time since the incident. DUI convictions typically increase premiums 80–150% compared to clean-record drivers, while suspended license violations may add 50–100%. Drivers completing their SR-22 requirement should expect rates to drop 20–40% within 12 months of filing removal, with full normalization taking 3–5 years as the violation ages off.
What Affects Your Rate
- Violation type and severity—DUI convictions carry the highest surcharges in Montana, typically 80–150% increases
- Time since violation—rates improve 20–40% in the first 12 months after SR-22 removal, with continued decline through year 5
- Location—Billings and Missoula drivers pay 15–25% more than rural Montana due to higher accident and theft rates
- SR-22 compliance history—a clean 3-year SR-22 period with no lapses qualifies you for standard carrier consideration
- Credit score—Montana allows credit-based insurance scoring, which significantly impacts post-SR22 rates for drivers rebuilding
- Age and experience—drivers under 25 with SR-22 face compounded surcharges, often exceeding $500/mo for full coverage
