Car Insurance in Montana: 2026 Rates & Requirements

Montana keeps a standard minimum, and the state's vast size combined with low population density keeps average premiums among the more affordable in the country, despite long rural driving distances.

Minimum Insurance Requirements in Montana

Montana requires drivers to carry at least $25,000/50,000 in bodily injury liability (per person / per accident) and $20,000 in property damage liability. Montana is an at-fault (tort) state: the driver who caused the accident, through their liability coverage, pays for the other party's injuries and property damage. These are legal minimums, not a safety net for your own finances — most independent advisors recommend carrying meaningfully higher limits than the state requires, especially if you own a home or have savings to protect.

What Drives the Cost of Car Insurance in Montana

Billings and Missoula carry somewhat higher premiums than the state's many small towns and rural counties, but Montana has no metro area on the scale of most states. Long stretches of rural highway, wildlife collisions, and winter weather all contribute to accident risk in specific ways here, but Montana's very low population density and low litigation activity are the main reasons the state stays affordable overall for drivers carrying a standard policy.
