About This Montana Report

This Montana report is based on 5 actual sold policies from our Montana clients during 2024–2025, covering Cascade County (Great Falls), Gallatin County (Bozeman), and Missoula County. All 5 are through Progressive — 4 full coverage and 1 liability-only. These are real issued policies with real premium outcomes, not estimates.

Why a smaller dataset? Montana is the 4th largest state by land area but ranks 44th in population — roughly 1.1 million residents spread across 147,000 square miles. Its largest city (Billings) has fewer than 120,000 people. This population thinness translates directly to lower insurance volume in any given agency. Our Montana clients reflect a full coverage-heavy book, consistent with a state where driving conditions — wildlife collisions, mountain roads, severe winter weather — make comprehensive and collision coverage a genuine practical need rather than a lender-only requirement.

Montana has one distinct characteristic worth knowing: it was historically one of the very few states with no mandatory auto insurance requirement — drivers could self-insure by posting a bond or cash deposit instead. Montana changed this and now requires liability insurance, but the lingering culture of minimal compliance means uninsured motorist rates in rural Montana run higher than national averages. Getting proper UM coverage in Montana is worth the added cost.

📊 Data note: With 5 policies across 3 counties (3 in Cascade, 1 each in Gallatin and Missoula), per-county figures for Gallatin and Missoula are single observations — treat them as individual data points, not county averages. Cascade County’s 3 consistent policies ($174.17 each) provide the most reliable benchmark.

⚡ Coverage type drives the spread

The gap from $43.66 to $228.05 is almost entirely explained by coverage type — Gallatin County’s $43.66 is liability-only, while Missoula’s $228.05 is full coverage. Montana full coverage rates cluster in the $170–$230 range across our dataset.

🦌 Wildlife collision risk matters

Montana ranks among the top states for deer and elk vehicle collisions per capita. Comprehensive coverage pays for wildlife strikes — a practical consideration that pushes many Montana drivers toward full coverage even for older paid-off vehicles.

Key Takeaways
  • Cascade County (Great Falls): 3 identical full coverage policies at $174.17/month — the most reliable benchmark in this dataset.
  • Missoula County: $228.05/month full coverage — Montana’s second-largest city, University of Montana campus, higher traffic and theft exposure than Great Falls.
  • Gallatin County (Bozeman): $43.66/month liability-only — Bozeman has grown rapidly as a tech and remote-work destination; this single liability policy is not representative of full coverage costs there.
  • All policies through Progressive — reflecting strong competitive pricing for Montana full coverage. We access additional carriers; call to compare.

Montana Insurance Context

Montana Minimum Liability Requirements

Montana requires 25/50/20 liability minimums: $25,000 per person bodily injury, $50,000 per accident, and $20,000 property damage. Montana is a tort (at-fault) state with no mandatory PIP — keeping liability-only premiums more accessible than no-fault states.

Wildlife Collision & Comprehensive Coverage

Montana consistently ranks in the top 5 states for deer/elk vehicle collisions per licensed driver. The Montana Highway Patrol estimates tens of thousands of wildlife strikes per year. Comprehensive coverage (which pays for animal strikes, unlike collision) is worth serious consideration for any Montana driver — even for older paid-off vehicles. If you’re currently liability-only and commute on rural highways, adding comprehensive may cost $20–$50/month and could protect against a $5,000–$15,000 claim.

SR-22 in Montana

  • Required after DUI, reckless driving, uninsured accidents, or license suspension
  • Maintained for 3 years from the triggering event date
  • Montana DMV accepts electronic SR-22 filings — we file same-day through Progressive
  • Non-owners SR-22 available for drivers without a registered vehicle

Montana’s Three Major Markets

Insurance rates in Montana largely follow population and traffic density. Billings (Yellowstone County) is the largest city and tends to see the highest full coverage rates — more traffic, more theft, higher repair costs. Missoula (our dataset) is a university city with younger-driver demographics and moderate urban density — full coverage runs $200–$230+ for standard profiles. Great Falls (Cascade County, our dataset) is smaller and more affordable — our 3 consistent policies at $174/month reflect a stable mid-market. Bozeman (Gallatin County) has seen explosive growth from remote workers and tech migration — rates are rising as density increases, though it remains more affordable than Missoula for full coverage.

Frequently Asked Questions — Montana Auto Insurance

What does auto insurance cost in Montana based on our data?

Our Montana dataset contains 5 policies across 3 counties from 2024–2025, all through Progressive. Cascade County (Great Falls) shows 3 identical full coverage policies at $174.17/month each — our most consistent Montana benchmark. Missoula County shows a single full coverage policy at $228.05. Gallatin County (Bozeman) shows a single liability policy at $43.66 — the most affordable in our Montana dataset, reflecting minimum-coverage compliance rather than full coverage on a vehicle. With only 5 policies, these figures represent individual data points rather than reliable county averages. Industry data generally places Montana in the lower-middle tier nationally for auto insurance costs, with full coverage for a standard-risk driver typically running $130–$220/month depending on county and vehicle — consistent with our Cascade County three-policy benchmark of $174.17.

What are Montana’s minimum auto insurance requirements?

Montana requires 25/50/20 liability coverage: $25,000 per person for bodily injury, $50,000 per accident, and $20,000 for property damage. Montana is a tort (at-fault) state with no mandatory PIP. Uninsured motorist coverage must be offered but can be waived in writing — Montana’s uninsured driver rate is approximately 9–11%. Montana has a notable legal wrinkle: it uses a pure comparative fault system, meaning you can recover damages even if you are 99% at fault, though your recovery is reduced by your percentage of fault. Montana also has no speed limit on some rural interstates — a distinctive driving environment that contributes to the state’s above-average traffic fatality rate per mile driven and factors into insurer risk assessment. Carrying higher liability limits than the minimum is advisable given Montana’s rural highway speeds and the potential for serious accidents.

Does Montana’s wildlife — especially deer and elk — affect auto insurance rates?

Yes — Montana has one of the highest rates of deer and large-animal vehicle collisions in the country. State Farm’s annual deer-vehicle collision report consistently ranks Montana among the top 10 states nationally for the probability of a deer strike, and elk and moose collisions — far more dangerous and damaging than deer — are a real seasonal risk on Montana’s highways. All animal-vehicle collisions are comprehensive claims, not collision claims, making comprehensive coverage particularly important in Montana. A single elk strike can total a vehicle outright — the average claim value for a large-animal collision in Montana runs well above the national deer-strike average. Drivers who drop comprehensive coverage to reduce premiums in Montana take on meaningful financial exposure during fall migration season, when animal collisions spike significantly on roads like US-2, US-93, and I-90.

How does SR-22 work in Montana?

Montana requires SR-22 after DUI, reckless driving, driving uninsured in an accident, or license suspension for serious violations. The filing period is typically 3 years from license reinstatement. Progressive — our sole Montana carrier — files Montana SR-22 electronically with the Montana Motor Vehicle Division (MVD). Montana’s current dataset does not include any SR-22 or non-owners policies, but both products are available through Progressive in the state. Non-owners SR-22 is particularly relevant in Montana’s smaller cities like Great Falls, Billings, and Missoula, where some residents live without vehicle ownership but need to maintain a driver’s license for employment. Montana’s 3-year SR-22 period is consistent with the national standard, and any lapse triggers immediate notification to the MVD with potential license re-suspension.

Is insurance more expensive in Missoula than in Great Falls or Bozeman?

In our very limited dataset, Missoula County’s single full coverage policy at $228.05 sits above Cascade County’s (Great Falls) three consistent policies at $174.17. Gallatin County’s (Bozeman) single liability policy at $43.66 is not comparable — it’s a different coverage type entirely. Missoula’s modestly higher rate is plausible: it’s Montana’s largest city and a University of Montana college town with higher traffic density than Great Falls, and its full coverage profile may reflect a higher-value vehicle. Bozeman (Gallatin County) is Montana’s fastest-growing city and has seen significant insurance cost increases as its population and traffic density have grown rapidly — but our single liability-only data point there doesn’t capture full coverage pricing. For current Bozeman full coverage quotes specifically, a direct carrier comparison is the most accurate approach given how quickly that market is evolving.
