Minimum car insurance requirements in Montana
All motor vehicles operated or parked on Montana roadways are required to be insured. Proof of insurance must be carried in your car at all times and must be available when:
Requested by law enforcement
Renewing vehicle registration
The vehicle is involved in a car accident
The minimum liability insurance requirements for private passenger vehicles in Montana are:
$25,000 per person and $50,000 per accident for bodily injury: As a major part of your liability insurance, bodily injury coverage covers medical bills for people other than the policyholder who are injured during an accident. Montana is an at-fault state, meaning the driver who is responsible for the collision is also responsible for paying for any resulting expenses, either through their car insurance provider or out of pocket.
$20,000 per accident for property damage: If it’s determined that an insured driver is at fault for an accident, this coverage pays for repairs to the property of the other involved parties. Additionally, property damage coverage can cover legal costs if the insured driver is involved in a lawsuit following the accident.
$50,000 per accident for uninsured/underinsured motorists: Uninsured and underinsured motorist coverage pays for costs caused by a driver with little or no insurance after a car accident. In Montana, this coverage is required to be offered, but drivers can reject it if they don’t want it.

Tips for getting cheap car insurance in Montana
Insurance companies look at a lot of information, such as your age and credit history, when determining your premiums. Each insurance company looks at these risk variables slightly differently, so shopping around to compare car insurance quotes is a good strategy for finding a good deal. Compare quotes from multiple insurers quickly to find the right insurance policy.
You can also take other steps to reduce car insurance costs, including:
Seek discounts, such as good driver or good student discounts.
Bundle your homeowners or renters insurance with your car insurance.
Maintain a good credit score.
Liability-only vs. full-coverage insurance in Montana
If you live in Montana, you can opt to carry liability-only auto insurance, which pays for expenses related to injuries and damage to the other party’s car if you cause an accident. Each state sets its own minimums for how much liability insurance it requires drivers to carry. Liability-only insurance can make sense if:
You have a low-value vehicle.
You can afford to repair or replace your car out of your own pocket.
Getting the cheapest insurance possible is your top priority.
For a higher level of protection, you can choose full-coverage insurance, which includes basic liability plus collision and comprehensive coverage. Collision coverage pays for damages to your car, even if you’re at fault for an accident. Comprehensive pays for damages caused by events out of your control, like vandalism, weather, and animals. Auto lenders and leasing companies typically require drivers to carry full coverage on a car they’ve financed.
You may also opt for full coverage if:
You have a high-value vehicle.
You wouldn’t be able to afford to repair or replace your car out of pocket.
Your car’s actual cash value (the payout you’d likely get if your car is totaled) exceeds your annual premium to carry full coverage.

How your city affects Montana insurance quotes
Car insurance premiums vary based on where you live in the state, and drivers in urban areas generally pay more than rural drivers.

Drivers in Missoula and Butte have below-average rates.

How your age affects your Montana car insurance rates
Because insurers generally equate age with experience level, your age will significantly affect how much you pay for car insurance. New drivers, who tend to be teens or people in their early 20s, typically pay more for insurance than drivers 25 and older.
The following table gives a high-level view of how age can affect insurance rates.

Quotes for young drivers
Multiple other factors influence how much drivers in each age group will pay for car insurance. Some increase rates for one age group more than another, while others impact all age groups evenly.
The following table compares how different insurance factors affect average monthly rates for drivers younger than 30. Like in most other states, teenagers and drivers under 25 pay the highest rates by age group in Montana because auto insurers account for less driving experience. Still, both Nationwide and Travelers offer a low monthly average rate of just $136 for full-coverage car insurance.
|Car Insurance Company||Full Coverage||With a DUI|
|Midvale Home & Auto||$179||$334|
Quotes for middle-aged drivers
The following table compares how different insurance factors affect average monthly rates for drivers between 30 and 59. On average, middle-aged drivers in Montana spend between $123 and $209 per month. With an average premium of $96 per month, Travelers provides the cheapest option for full-coverage car insurance.

Quotes for senior drivers
Different insurance factors affect average monthly rates for drivers 59 and older. Senior drivers in Montana tend to find lower rates in their 60s and 70s than in their 80s and people who choose full coverage. Depending on varying financial situations, drivers in this age group save by choosing liability-only insurance over a full-coverage policy. And drivers with clean records pay less for coverage than those with an accident or DUI in their driving history.
Montana car insurance FAQs
Offering a monthly quote of just $115 for full-coverage car insurance, Travelers presents Montana drivers with the cheapest car insurance option in the state. Other top providers offering the cheapest quotes include Nationwide with $134 per month and State Farm with $183. A smaller auto insurer with a low monthly rate of $117 per month is Foremost Signature.
To find the best rate for your specific insurance needs and driving history, compare quotes from multiple auto insurers. Some auto insurers will work better than others, so shopping around is crucial. Notably, the cheapest auto insurer for middle-aged and senior drivers at varying coverage levels and driving histories is Safeco.
Montana ranks in the top 50% of safest states, but around 17% of drivers in the state have a driving incident on their record. Notably, the state ranks 9th in number of drivers with a DUI and 18th in number of drivers with speeding tickets on their driving record. Auto insurers may view the frequency of these incidents as a reason to increase rates statewide.
Location-based factors in Montana influence rates, including weather and climate, population density, crime rates, and more. Specifically, Montana recently experienced historic flooding that devastated areas in Stillwater, Carbon, and Park counties. Unprecedented events like this, along with more typical flooding, likely increase rates statewide to account for risk levels.
On average, Montana drivers spend $241 per month on auto insurance, slightly exceeding the national average of $233 per month. The state ranks as the 17th most-expensive state for purchasing car insurance in the country. The average car insurance premiums in nearby states of Idaho, North Dakota, South Dakota, and Wyoming are more affordable than in Montana.
On top of statewide factors related to weather and population density, individual insurance rates ultimately fluctuate based on driving records, credit history, age, vehicle type, and coverage level. In the industry, rates have been trending upwards across multiple car insurance providers due to increased costs of repairs and replacements and supply chain issues.

Our data scientists calculate ICS ratings using industry and financial ratings, as well as customer and claims satisfaction ratings. Nationwide scored an A+ from A.M. Best and an A+ from Standard & Poor’s.

No, you don’t need personal injury protection (PIP) coverage in Montana to remain in compliance with state law. MedPay, or medical payments coverage, is also not required for Montana drivers. The only required coverage in the state includes bodily injury liability, property damage liability, and underinsured/uninsured motorist coverage.
Living in an at-fault state, Montana drivers who cause an auto collision must take on the financial responsibility for any of the expenses resulting from the accident. This responsibility makes selecting the right amount of coverage for your insurance needs important.
Yes, Montana drivers must purchase the state’s minimum required car insurance. Specifically, drivers need to purchase the following:
$25,000 per person and $50,000 per accident for bodily injury liability
$20,000 per accident for property damage liability
$50,000 per accident for uninsured/underinsured motorists coverage
Per-person property damage liability isn’t required. Bodily injury liability insurance covers medical bills for other parties injured in an accident in which you were at fault. Similarly, property damage liability covers the costs of vehicle damage and other repairs. Uninsured and underinsured motorist coverage protects you if you have an accident with an uninsured motorist.
As with most other states, Montana car insurance follows the car rather than the insured driver. This means that if someone borrows your car and crashes it, your vehicle coverage will kick in to cover any applicable costs. The insurance coverage of the borrower will kick in as secondary coverage if and when needed to cover the costs of the car accident.
Unless the driver borrowing your vehicle doesn’t have a driver’s license, your auto insurance company shouldn’t object to providing applicable coverage. As a rule, don’t allow unlicensed drivers to borrow your vehicle.
Full-coverage car insurance extends coverage beyond Montana’s minimum-required car insurance that covers costs of property damage and bodily injury you may cause other parties in an accident. A full-coverage policy also includes collision and comprehensive coverage, and additional insurance extensions exist for you to choose from, depending on your insurer.
Collision coverage protects you and your vehicle in the event of an auto accident, and comprehensive coverage deals specifically with theft, vandalism, and natural disasters. Not everyone needs a full-coverage policy, especially considering the increased cost. Drivers with inexpensive vehicles may stick with less coverage.
