Car Insurance in Idaho: 2026 Rates & Requirements

Idaho is one of the more affordable states in the country for car insurance, with a standard minimum and low population density keeping accident frequency, theft rates, and litigation activity all below what most states see.

Minimum Insurance Requirements in Idaho

Idaho requires drivers to carry at least $25,000/50,000 in bodily injury liability (per person / per accident) and $15,000 in property damage liability. Idaho 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 Idaho

Boise accounts for a disproportionate share of the state's traffic and accident claims relative to its size, but even Idaho's largest metro area has relatively light congestion compared to national norms, which keeps premiums there closer to the rest of the state than in more urbanized parts of the country. Winter driving conditions across much of the state add some seasonal risk, but Idaho's low uninsured-driver rate and generally low-litigation environment are the main reasons the state consistently ranks among the more affordable options nationally.
