Cheapest auto insurance companies in Montana for minimum coverage
If you're a Montanan looking for the cheapest car insurance, you could buy a minimum coverage policy, which only meets the coverage requirements mandated by state law.
We found that the cheapest minimum coverage policies in Montana are sold by State Farm and Progressive.
State Farm cost our sample driver $299 per year, while Geico was priced at $358 — both are much more affordable than the overall state average of $466.

Shoppers should be wary that a minimum coverage policy is the bare minimum protection you can buy. In Montana, a minimum policy will only cover you up to $50,000 in bodily injury liabilities and $20,000 in property damage liability.
USAA is another affordable option for Montana drivers. If you qualify, it's the most affordable of our sample insurers. But only current and former military members and their families can buy a USAA policy.
The cheap liability-only rates provided may differ greatly from yours depending on your driving history, age, location and other factors.
Cheapest company for full coverage: State Farm
Full coverage policies don't just protect you against liability costs. Through collision and comprehensive insurance, these policies cover damage to your own vehicle for both on- and off-road incidents.
Montanans can find the cheapest full coverage policies with State Farm. Geico ranks a distant second.
The average cost of a full coverage policy in Montana is $2,297 per year. In Montana and elsewhere, it's best to shop around if you're trying to find the cheapest option:
Full coverage policies pay to repair damage to your car caused by driving and non-driving perils. As a rule of thumb, a full coverage policy is worth it if the value of your car exceeds the cost of comprehensive and collision insurance plus your deductible.
Cheap car insurance for drivers with prior incidents
Drivers who have recent crashes or tickets are likely to pay more for car insurance. This makes it even more important to shop around and look for the insurer that offers the most affordable coverage for you.
Cheapest for drivers with an accident: State Farm
We found that State Farm had the cheapest rates after our sample driver got into an at-fault accident. On average, insurance rates in Montana go up by 39% after an accident. State Farm's rates only increased by 15% from a low base, which is not much for those with an accident history.
Cheapest car insurance for people with a speeding ticket: State Farm
Insurers don't look favorably on drivers with speeding tickets because they indicate a higher likelihood that you'll be involved in an accident in the future. But some insurers raise rates more than others, and we found that State Farm had the best rates for drivers recently caught speeding. We found a typical price of $1,337 per year there, which is 52% less than the average across all insurers.
Cheapest car insurance for drivers with a DUI: State Farm
Driving under the influence is a serious offense, and car insurance companies tend to increase your rates significantly if you get a DUI. We found that the average cost of a full-coverage policy after one DUI is $3,550 per year — a 54% increase. But State Farm's rates only increased by $91 per year.
Drivers convicted of a DUI are often required to get an SR-22 proof of insurance from their insurer, which may increase your rates even more.
Cheapest car insurance for drivers with poor credit: State Farm
Insurers consider your credit score when setting insurance prices because they've found a correlation between a driver's credit and how often they file claims. State Farm has the best car insurance rates for Montana drivers with poor credit , typically $1,903 per year. Geico is also on the affordable side, with an average rate of $2,336 annually.
Cheapest car insurance for young drivers: State Farm
Insurers almost always charge younger drivers more because they've found younger people get in more accidents and make more insurance claims. But not every insurer increases rates at the same amount.
We recommend State Farm as the most affordable option for teen drivers. It charges only $852 per year for minimum coverage, and $3,130 for full coverage. Both are at least 42% less than the typical rate we found across all insurers.
*USAA is excluded from rankings because it is only available to current and former military members and their families.
The easiest, most effective way for most teen drivers to lower their car insurance rates is to share a policy with an older adult, such as a parent or sibling. Rates for one 18-year-old and one older adult will almost always be much lower than for an 18-year-old on their own.
Cheapest for young drivers with one accident: State Farm
Car accidents typically result in higher car insurance rates, especially if you're an inexperienced younger driver. But State Farm had much more affordable rates than average, charging only $3,654 per year for a full coverage policy after one crash.
Many insurers offer discounts to young drivers for taking supplementary training beyond what's required to get your license. You may also be able to lower your rate by getting good grades in high school or college.
Cheapest for young drivers with one speeding ticket: State Farm
We found that State Farm has the lowest price for young drivers with a speeding ticket. There, you'll pay $3,392 for a year of full coverage, compared to $6,720 across all insurers.

*Overall rank takes both claim satisfaction and customer service ratings into account. Explanation of ratings are in the Methodology section. USAA was not included in rankings, as only military members, veterans and their families are eligible. Farmers Insurance was not ranked in the survey due to limited respondents.
To help Montana car insurance shoppers make an informed decision, we also collected customer service information from three other reputable sources: the National Association of Insurance Commissioners (NAIC), J.D. Power and AM Best.
2019 NAIC complaint index
2020 J.D. Power Claims Satisfaction
AM Best Rating
|Mountain West Farm Bureau||2.08||—||B++|
The NAIC's Complaint Index compares the number of complaints an insurer has received with its size. A lower score means fewer complaints, and the national average score is 1.00, so insurers with a score lower than 1 can be considered better than average.
J.D. Power conducts an annual nationwide survey of car insurance claims satisfaction. Higher scores are better, and the best possible rating is 1000.
AM Best's Financial Strength Rating is a letter grade describing the overall financial health of an insurer. The best possible grade is A++.
Auto insurance in Montana: Minimum coverage requirements
Montana requires car insurance policies include, at minimum, the following limits of coverage:
- Bodily injury (BI) liability: $25,000 per person / $50,000 per accident
- Property damage (PD) liability: $20,000 per accident
Montana requires minimum auto insurance liability of $25,000 per person for bodily injury protection and up to $50,000 per accident, and $20,000 for property damage per accident. The state doesn’t require uninsured motorist coverage but requires that insurance companies offer it as part of liability coverage. Drivers have the option of declining this coverage in writing.
While these limits represent the minimum amount of insurance coverage you can have, you should consider adding more, as damages above these limits could require you to pay out of pocket. The amount of liability insurance you should have typically depends on the amount of assets you have at risk in the case of a lawsuit. A good rule of thumb is to have liability limits matching the value of your assets.
