Illustrative estimates for layout and comparison purposes; see our methodology.
Montana requires liability coverage on every registered vehicle. The legal floor:
Minimum coverage keeps you legal, not necessarily solvent: the average new truck costs more than $20,000 to replace, so one at-fault accident can outrun your property-damage limit.
Minimums cross-checked against Insurance Information Institute and state DOI sources, July 2026; see our methodology. Rules change; verify current minimums with your state's Department of Insurance.
Premiums swing inside Montana: traffic density, claim frequency, and repair costs vary from ZIP to ZIP, so quote with your exact address.
Rates in Montana run about 10% above the national average, at about $46/mo for liability and $221/mo for full coverage. Traffic density, weather claims, repair costs, and uninsured drivers all feed into local pricing, and comparing 3 or more quotes is the fastest way to come in under the state average.
Fines, suspension, SR-22 filings, and reinstatement fees, per Montana law. Billie's take: a minimum policy is cheaper, and state fines taste terrible. Verify the exact numbers with the Montana Department of Insurance.
