Minimum Coverage Requirements in Montana

Montana mandates minimum liability coverage of 25/50/25 ($25,000 bodily injury per person, $50,000 per accident, $25,000 property damage). The Montana Motor Vehicle Division requires SR-22 filing after DUI convictions, license suspensions due to point accumulation (30 points in 36 months), driving without insurance, and certain at-fault accidents involving injury or significant property damage. SR-22 must remain active for 3 years from the date the Montana MVD lifts your suspension, and any lapse triggers immediate license re-suspension and restarts the 3-year clock.

How Much Does Car Insurance Cost in Montana?

High-risk auto insurance in Montana costs $190–$400/mo for liability-only coverage and $250–$500/mo for full coverage, based on available industry data for drivers with DUI, SR-22 requirements, or multiple violations. Your rate depends on violation type (DUI costs more than a single at-fault accident), time since the incident (rates drop 20–30% each year you stay violation-free), your age, vehicle, credit tier, and which non-standard carriers are willing to write you in your county.

Minimum Liability

Montana's 25/50/25 state minimums for high-risk drivers with SR-22 filing. This tier satisfies legal requirements but leaves you financially exposed in serious accidents.

Standard Liability

Higher liability limits (100/300/100) often required by courts after DUI or mandated by lenders. Adds $50–$70/mo over minimums but provides meaningful protection against civil judgments.

Full Coverage

Liability plus comprehensive and collision for financed vehicles. Highest cost tier but required if you have a car loan or lease and want your own vehicle repaired after an at-fault accident.

What Affects Your Rate

Violation type and severity — DUI convictions raise rates 180–250%, while a single speeding ticket under 15 mph over raises rates 15–25%
Time since violation — rates decrease 20–30% each year you remain violation-free, with the steepest drop after year 3
Point total on your Montana driving record — drivers approaching the 30-point suspension threshold pay higher premiums even before suspension
SR-22 filing requirement — adds $15–$35 to file, but the underlying violation increases premiums $1,500–$3,500 annually for 3–5 years
Non-standard carrier availability in rural counties — fewer insurers compete in eastern Montana, leading to 10–20% higher premiums than Billings or Missoula metro areas
Coverage level selected — dropping collision/comprehensive after loan payoff cuts premiums 40–50% but leaves you paying out-of-pocket for vehicle damage
