What Car Insurance Is Required in Bozeman?
Drivers in Bozeman follow Montana’s rules. Every car insurance policy for a vehicle registered and driven in Montana must include at least:
- Liability coverage of $25,000 per person and $50,000 per crash for injuries and $20,000 for property damage (25/50/20)
- Uninsured motorist coverage at 25/50, which comes with the policy unless you sign a form rejecting it
The liability-only prices on this page use 25/50/10 limits, so their $10,000 in property damage coverage is below that minimum. Our Montana requirements guide covers proof of insurance, the state’s verification system and the penalties for driving uninsured.
How to Lower Your Car Insurance Rate in Bozeman
- Compare Safeco and State Farm first. They have the two lowest full-coverage averages of the five major insurers we compared in Bozeman, about $82 and $149 a month.
- Quote several insurers. Among the five major insurers we compared in Bozeman, the lowest and highest averages are about $145 a month apart for the same driver and car.
- Ask for a credit re-rate at renewal. Montana insurers must re-rate your policy using a current credit report or insurance score at your annual renewal if you ask, under 33-18-605 MCA, which helps if your credit has improved.
- Compare at every renewal. Over the past nine months, State Farm has raised its average 2.3%, so the order in our table can shift.
- Ask about discounts and check your deductible. Many insurers lower rates for a clean driving record, paying in full or insuring more than one car, so ask which auto insurance discounts you qualify for. Our full-coverage prices use $500 deductibles. A higher deductible lowers your premium but means you pay more yourself after a claim; see how deductibles affect your rate.
- Insure your car and home together. A multi-policy discount is a common way to save, so check average home insurance rates in Montana, and compare home insurance quotes alongside your car quotes. Renting? A renters insurance policy can qualify too.

How We Calculated Bozeman Car Insurance Rates
Insurers must file their rates and rating rules with each state’s insurance regulator. Quadrant Information Services uses those filings to calculate what each insurer would charge a specific driver, and InsuranceQuotes analyzes those prices. This page uses rates in effect on Aug. 31, 2026.
- Sample: 10 full-coverage premiums from five insurers across two Bozeman ZIP codes, plus the same number of liability-only and 50/100/50 premiums.
- Driver: a single 40-year-old driver, licensed 24 years, with good credit and no accidents or violations, driving a 2024 Toyota Camry LE they own, for personal use.
- Coverage: full coverage is 100/300/100 liability with $500 comprehensive and collision deductibles and 100/300 uninsured and underinsured motorist coverage. We also price 50/100/50 with the same deductibles, and liability-only coverage at 25/50/10 limits, with 25/50 uninsured and underinsured motorist coverage and no comprehensive or collision. Montana’s minimum is now 25/50/20, so our liability-only prices use lower limits than the law requires: $10,000 in property damage liability instead of $20,000.
- Calculation: for each insurer we take its lowest eligible price in each ZIP code and average those prices across the ZIP codes. The overall average is the mean of every insurer-and-ZIP price. Monthly figures are annual premiums divided by 12 and rounded.
- Rankings: we name a cheapest insurer only where it’s priced in at least half the ZIP codes and its lead over the next insurer isn’t so wide that it looks like an outlier. Annual prices within 3% of each other are called effectively tied.
- Rate changes: we compare the same insurer in the same ZIP codes, for the same driver and coverage, in rates as of Nov. 30, 2025, and Aug. 31, 2026. All five insurers are in both sets of rates. Rate-change percentages are calculated from the annual premiums shown; other percentages use the rounded monthly figures.
- Insurers marked *: priced from published 2026 Montana rate studies, scaled to our benchmark driver. They aren’t included in our averages or rankings.
- What this isn’t: a quote. These are modeled prices for one driver profile, calculated from insurers’ rate filings. Your price depends on your ZIP code, vehicle, driving record, coverage choices and discounts.
Coverage requirements come from Montana law and the Montana Commissioner of Securities and Insurance. We refresh these figures when new rate data is released.
