State Requirements
Montana requires 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. These are the minimums needed to register a vehicle, but drivers with DUIs, uninsured accidents, or serious violations must also file SR-22 proof of financial responsibility for 3 years. Montana does not offer hardship licenses during suspension periods, making SR-22 compliance and continuous coverage mandatory for reinstatement.
Cost Overview
High-risk auto insurance in Montana costs 2–4 times more than standard rates due to violation type, filing requirements, and carrier availability. A DUI adds $1,800–$3,500 annually to premiums, while SR-22 filing for lapses or points typically adds $800–$1,500. Montana's rural geography and limited non-standard carrier competition mean rates in cities like Billings and Missoula are often 10–20% lower than in rural counties.
What Affects Your Rate
- Violation type: DUI adds 120–250% to premiums; reckless driving adds 60–100%; at-fault accidents add 40–80%
- SR-22 duration: rates decline 15–25% after the first year of continuous coverage without new violations
- Location: Billings and Missoula have more carrier options and rates 10–20% lower than rural counties
- Vehicle type: high-performance, modified, or luxury vehicles increase premiums 20–50% for high-risk profiles
- Payment plan: paying in full saves 5–10% compared to monthly installments with fees
- Age and experience: drivers under 25 with violations pay 30–60% more than drivers over 30 with identical records
