Minimum Coverage Requirements in Montana
After a DUI or major violation in Montana, your current insurance company will typically issue a non-renewal notice rather than an immediate cancellation—meaning your policy continues until its expiration date, but will not be renewed. The Montana Motor Vehicle Division requires you to carry continuous liability coverage and file an SR-22 certificate for 3 years following most serious violations. If your insurer drops you entirely or does not offer SR-22 filings, you must find a non-standard carrier before your policy ends to avoid a coverage lapse, which triggers additional penalties and extends your filing period.
How Much Does Car Insurance Cost in Montana?
Insurance premiums for Montana drivers with DUIs or serious violations typically increase 50–200% compared to standard rates, with DUI convictions often doubling or tripling costs. Senior drivers may see smaller percentage increases than younger drivers due to otherwise clean long-term records, but absolute costs remain high. Rates begin to decrease after 3–5 years if no additional violations occur, with the most significant drop occurring once the violation ages beyond the carrier's lookback period—typically 5 years.
What Affects Your Rate
- Violation type—DUI convictions carry the highest surcharges, often 100–200% increases, while speeding violations may add 20–50%
- Time since violation—rates decrease gradually after year 3, with significant drops at the 5-year mark when violations fall off most carriers' rating periods
- Carrier options—non-standard carriers in Montana such as Bristol West, The General, and Dairyland specialize in high-risk drivers and offer SR-22 filings, but availability varies by county
- Age and driving history—senior drivers with decades of clean history before a recent violation often qualify for lower surcharges than younger drivers with shorter track records
- Coverage level—choosing state minimum liability significantly reduces premium but exposes assets to risk; many senior drivers benefit from higher limits relative to the modest cost difference
- Location—Billings and Missoula have more non-standard carrier options than rural counties, affecting both availability and competitiveness of rates
