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.

Liability Insurance
Montana's 25/50/20 minimums are the legal floor, but a single at-fault accident can easily exceed $25,000 per person in medical costs. High-risk drivers face higher premiums for these minimums—often $150–$300/month—and courts may require higher limits as part of DUI sentencing. Montana is a fault state, meaning you are financially responsible for damages if you caused the accident.
Meets state minimums
SR-22 Insurance
SR-22 is not a separate policy—it is a certification your insurer files with the Montana Motor Vehicle Division proving you carry at least 25/50/20 liability. The filing itself costs $15–$35, but the policy backing it can cost $2,400–$5,200 annually for DUI or serious violation profiles. If your policy lapses or cancels during the 3-year requirement, your insurer notifies the state and your license is suspended immediately.
Optional but offered
Uninsured Motorist Coverage
Montana law requires insurers to offer uninsured/underinsured motorist coverage at the same limits as your liability policy, and you must decline it in writing. For high-risk drivers who have been in accidents, this coverage protects you if the at-fault driver has no insurance or insufficient limits. It typically adds $10–$25/month to high-risk policies and is one of the few ways to recover costs without a lawsuit.
Lender-required if financing
Comprehensive & Collision
If you financed or leased your vehicle, the lender requires full coverage (comprehensive and collision) regardless of your driving record. High-risk drivers pay 40–80% more for these coverages than standard profiles, and many non-standard carriers require higher deductibles ($1,000–$2,500) to offset risk. Montana's weather—hail, ice, and animal collisions—makes comprehensive especially relevant for rural drivers.
Varies by carrier
Non-Standard Auto Insurance
Non-standard carriers specialize in high-risk profiles and are often the only option immediately following a DUI or suspension. These policies cost more upfront but accept drivers that standard insurers decline, and some offer rate reductions after 6–12 months of claims-free driving. Montana has fewer non-standard carriers than larger states, so comparison shopping is critical.

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
Minimum Liability
$200–$300/mo
State-required 25/50/20 liability with SR-22 filing for drivers with one DUI or major violation. Non-standard carriers often require 6-month policies paid in full or monthly installments with fees.
Standard Liability
$275–$385/mo
Increased liability limits (50/100/50 or 100/300/100) often required by courts or employers following a DUI. Adds $50–$100/month over minimums but provides meaningful protection against lawsuit judgments.
Full Coverage
$350–$435/mo
Comprehensive and collision added to liability for financed vehicles or high-value cars. High-risk drivers typically face $1,000–$2,500 deductibles and limited coverage for modified or older vehicles.
