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.

SR-22 Certificate Filing

An SR-22 is not a type of insurance—it is a certificate your insurer files electronically with the Montana Motor Vehicle Division proving you carry the state-required minimum liability coverage. Not all carriers offer SR-22 filings; most standard insurers will non-renew your policy rather than file on your behalf, requiring you to move to a non-standard carrier.

Non-Standard Auto Insurance

Non-standard auto insurance is coverage sold by carriers that specialize in high-risk drivers—those with DUIs, violations, lapses, or suspensions on their record. These carriers offer SR-22 filings and accept drivers standard insurers will not renew.

Liability Insurance

Drivers 65 and older may benefit from higher limits—such as 100/300/100—as medical costs from accidents involving senior drivers or passengers often exceed state minimums, and assets accumulated over a lifetime are at risk in liability claims.

Uninsured/Underinsured Motorist Coverage

Montana does not require uninsured motorist coverage, but it protects you when an at-fault driver lacks insurance or carries only state minimums. For senior drivers on fixed incomes, medical bills from an accident caused by an uninsured driver can be financially devastating—this coverage fills the gap when the other driver cannot pay.

Medical Payments Coverage

Medical payments coverage pays for medical expenses for you and your passengers regardless of fault, up to your policy limit. Since Medicare does not cover all accident-related costs immediately and may seek reimbursement from settlements, MedPay provides immediate funds for deductibles, copays, and uncovered treatments following an accident.

What Affects Your Rate

  • 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
