You can trust the prices we show you because our data analysts take rigorous measures to eliminate outliers and inaccuracies in pricing data, which include rates from every locale in Idaho where coverage is offered and data is available. When comparing rates for different coverage amounts, ages and backgrounds, we change only one variable at a time, so you can easily see how each factor affects pricing.

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 among the cheapest five auto insurance options for 67 of the 70 driver profiles we examined.

Minimum required auto insurance in Idaho

  • $25,000 bodily injury liability per person.

  • $50,000 bodily injury liability per accident.

  • $15,000 property damage liability per accident.

Insurance companies are also obligated to include uninsured motorist coverage in your policy. However, you can decline this coverage in writing.

For more help understanding how Idaho’s required and optional coverages work, see NerdWallet’s guide to state minimum car insurance.

Alternative car insurance in Idaho

If you’re having trouble obtaining car insurance from traditional insurers because of a bad driving record, poor credit or other factors, the Idaho Automobile Insurance Plan can help you get a high-risk policy from an Idaho insurer.

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.

  • For drivers with one at-fault crash, we added a single at-fault crash that happened six months ago, resulting in $10,000 in property damage and no bodily injury claim.

  • For drivers with a DUI, we added a single drunken driving violation that happened six months ago.

We looked at 35-year-old drivers to find the cheapest company overall, the cheapest company for minimum coverage and the cheapest company for drivers with poor credit in states where credit history is used to price rates. We looked at 20-year-old drivers to find the cheapest company for young drivers.
