State Requirements
Montana requires minimum liability coverage of 25/50/20: $25,000 for bodily injury per person, $50,000 per accident, and $20,000 for property damage. SR-22 certification is mandated for DUI convictions, license suspensions for accumulating excessive points, driving without insurance, and certain repeat violations. Drivers with points from standard violations like speeding tickets or at-fault accidents typically do not need SR-22 unless their license is suspended. Montana operates on a point system where 30 points in 36 months triggers license suspension.
Cost Overview
High-risk auto insurance premiums in Montana are driven by violation type, time since the offense, and carrier underwriting guidelines. Drivers with a DUI pay the highest premiums—often 2.5–3.5 times the standard rate—while those with speeding tickets or at-fault accidents see increases of 20–60%. Rates decline as violations age off your record, with the steepest drops occurring after the first year and again when points fully expire at 3 years.
What Affects Your Rate
- Type of violation: DUI convictions increase premiums more than speeding tickets or at-fault accidents
- Time since offense: Rates drop significantly after the first year and again when violations age off at 3 years
- SR-22 filing requirement: Adds $15–$35 filing cost and restricts carrier options to those offering SR-22 in Montana
- Age and driving history: Younger drivers with violations face steeper increases than drivers over 25 with otherwise clean records
- Location: Urban areas like Billings and Missoula see higher premiums than rural counties due to accident frequency and repair costs
- Non-standard vs. standard market: Drivers who can access standard carriers after 1–2 years pay 30–50% less than those in the non-standard market
