Cheapest car insurance for military families

If you're an active member of the military or a veteran — or have an immediate family member who is — chances are you'll get a relatively cheap rate with USAA, a company that isn't available to the general public.

Because of that restriction, USAA isn't ranked with the others, but it was the cheapest auto insurance option for 56 of the 70 driver profiles we examined.

Minimum required auto insurance in Montana

Montana drivers are required to carry liability insurance, which helps cover others’ injury costs or property damage if you’re at fault in an accident.

The minimum limits are:

  • $25,000 bodily injury liability per person.

  • $50,000 bodily injury liability per accident.

  • $20,000 property damage liability per accident.

While this will allow you to drive legally, experts suggest getting more than the bare minimum to be better protected in Big Sky Country. For instance, a single at-fault accident could easily leave you owing more than $20,000 in repairs, and you'd be stuck paying the difference out of pocket.

You may also want to consider common optional coverages such as comprehensive coverage, which helps replace your car if it’s stolen, or uninsured motorist protection, which helps cover your medical treatment if you’re hit by a driver who lacks insurance.

Check out NerdWallet’s guide to state car insurance requirements for more details on the required and optional parts of your Montana auto policy.

Alternative car insurance in Montana

Drivers who try and fail to buy car insurance through the open market could qualify for coverage through the Montana Automobile Insurance Plan.

Methodology

For our “good driver” profile, NerdWallet averaged insurance estimates for single male and female drivers with good credit and no tickets or violations. The analysis included 5-10 of the largest insurance companies in each state; smaller insurers were also included when rates were available. Liberty Mutual and its subsidiaries were excluded from our analysis as rates were not available.

For full coverage policies, we used the following coverage limits:

  • $100,000 bodily injury liability per person.

  • $300,000 bodily injury liability per accident.

  • $50,000 property damage liability per accident.

  • $100,000 uninsured motorist coverage per person.

  • $300,000 uninsured motorist coverage per accident.

  • Collision coverage with a $1,000 deductible.

  • Comprehensive coverage with a $1,000 deductible.

In states where required, minimum additional coverages were added. Some policies include additional coverages at the insurer’s discretion.

We used a 2020 Toyota Camry L for all drivers and assumed 12,000 annual miles driven.

We analyzed rates for drivers 20 to 70 years old in ten-year increments. For the average cost of full and minimum coverage in each state, we looked at 35-year-old drivers.

We used the same assumptions for all other driver profiles, with the following exceptions:

  • For drivers with minimum coverage, we adjusted the numbers above to reflect the minimum required coverage by law in the state.

  • We changed the credit tier from “good” to “poor” as reported to the insurer to see rates for drivers with poor credit.
