Local insurance tip
Montana has no mandatory minimum for Uninsured Motorist coverage, but its vast rural highways mean accidents involving uninsured or underinsured drivers can happen far from help. Adding UM and comprehensive coverage is especially important for drivers who regularly travel remote two-lane highways where deer, elk and livestock collisions are a genuine daily risk.

South Dakota is the closest neighbor in cost.
Rate by Cities (Top 10)

City Insight
Montana's city rates are relatively compressed, with Billings leading modestly as the state's largest city. Helena and Missoula are the most affordable major cities, their university and government demographics keeping claim frequency below what Billings and Kalispell pay.
Rate by Counties (56)
Compared to MT avg ($215)
County Insight
The eastern plains counties form the most expensive tier. Big Horn, Blaine and Phillips counties lead the state, their combination of remote highways, livestock collision exposure and limited emergency response infrastructure driving rates above the more populated western counties.
What Every Montana Driver Needs To Know
What are the minimum car insurance requirements in MT for 2026?
Montana requires 25/50/20 minimums: $25,000 bodily injury per person, $50,000 per accident and $20,000 for property damage. Montana is an at-fault state and does not require PIP or Uninsured Motorist coverage.
How serious is the wildlife collision risk in Montana?
Montana consistently ranks among the top states nationally for deer, elk and livestock collisions per mile driven. These are comprehensive claims (not collision claims), meaning a liability-only policy leaves you fully exposed. On many Montana highways, particularly at dawn and dusk, wildlife strikes are a near-daily occurrence for local drivers. Comprehensive coverage is strongly recommended statewide.
Does Montana have any unique insurance rules for rural drivers?
Montana does not have unique rural-specific insurance rules, but its vast geography creates practical considerations that urban-state drivers rarely face. Emergency response times in remote counties can exceed an hour, medical evacuation by air is common after serious accidents and the nearest trauma center may be 100 or more miles away. Medical Payments (MedPay) coverage is particularly valuable for Montana drivers as a result.
What are the penalties for driving uninsured in Montana?
Driving without insurance in Montana results in a fine of up to $500 for a first offense and license suspension. Reinstatement requires proof of current insurance and payment of applicable fees. Repeat offenses carry higher fines and may require SR-22 filing for three years. Montana uses an electronic verification system to monitor insurance status.
