The average Idaho driver pays $1,901 a year, or $158 a month, for full coverage car insurance. Choosing only the state’s minimum liability requirement instead brings that number down to $594 a year, or $50 a month. Since these figures reflect statewide averages, your own quote may land above or below them.

A number of variables shape what you’ll actually pay, including your location, age, driving record, credit score, and vehicle type. Insurers additionally weigh risks specific to your state, such as accident frequency, medical and repair costs, theft, and weather exposure. This is one reason urban drivers usually see higher premiums than those in less populated areas.

Some factors are within your control, though. A clean driving record, a stronger credit score, bundled policies, and comparing quotes across insurers can all work in your favor to lower your premium.

What does each coverage type include?

  • State minimum coverage: Meets your state’s legal requirements, covering liability only. It’s the cheapest option, but leaves you with minimal protection in a serious accident.
  • Liability only: Covers damage and injuries you cause to others, but not your own vehicle or injuries.
  • Comprehensive coverage: Pays for damage to your car from non-collision events, like theft, fire, or weather.
  • Collision coverage: Pays to repair or replace your car after an accident, regardless of who’s at fault.
  • Full coverage: Combines liability with comprehensive and collision coverage, protecting your own vehicle too. It costs more, but offers the most complete protection.
  • Non owners: Made for drivers without a vehicle of their own who borrow cars now and then and need liability coverage in place.

Ways to bring your rate down in Idaho:

  • Shop at least three insurers before deciding, since the first quote rarely turns out to be the best one
  • Combine your home and auto coverage with one insurer to often unlock savings
  • Ask about every discount you might be eligible for
  • Stay violation-free, since a clean record signals lower risk and keeps premiums in check
  • Pay out of pocket for minor damage instead of filing a claim, which helps protect your rate from rising

How much car insurance coverage do you need in Idaho?

Drivers in Idaho must carry at least the state’s minimum liability coverage. This covers damage you cause to others, but not your own car or medical bills – if you’re at fault in a crash, you’d pay those costs yourself unless you have more coverage.

Minimum liability breaks down into two parts:

  • Bodily injury liability pays for others’ medical costs if you injure them. The “per person” limit caps what’s paid for one individual; the “per accident” limit caps the total for everyone.
  • Property damage liability pays to repair or replace others’ property, like their car or a fence.

Many drivers choose full coverage instead, which adds comprehensive and collision on top. It costs more, but protects your own vehicle too – from accidents, theft, or weather. If you’re financing or leasing, your lender likely requires it.

How much does car insurance cost by city in Idaho?

Car insurance rates shift noticeably by city across Idaho. In Meridian and Boise City, drivers pay between $1,661 and $1,682 a year, while Rexburg, Idaho Falls, and Pocatello come in well above that.

That’s because insurers price risk based on location. Cities with dense traffic, elevated accident rates, or more frequent theft and vandalism carry higher premiums, while quieter, less populated areas with fewer claims tend to stay cheaper.

How does age affect car insurance rates in Idaho?

Age is one of the biggest factors insurers use to determine how much you pay for coverage. Generally, premiums are highest for teen drivers, drop after age 25, stay relatively stable through adulthood, then rise again once drivers reach their early 70s. That’s because insurers view both very young and older drivers as higher risk – younger drivers due to limited experience, and older drivers due to slower reaction times and changes in vision.

Here’s a closer look at what you might pay in Idaho based on your age and gender.

Car insurance rates for young drivers in Idaho

If you’re a young driver, you can expect to pay above-average premiums. Insurers see young drivers as high-risk, which means higher premiums until you gain more experience behind the wheel.

For instance, 20-year-old male drivers in Idaho pay an average of $4,315 per year for car insurance, while females of the same age pay $3,626.

But by the time you turn 25, insurance premiums drop to $2,415 a year on average for male drivers and $2,216 for female drivers.

Age of driverAverage annual cost for Male driversAverage annual cost for Female drivers
20$4,315$3,626
21$3,549$3,028
22$3,245$2,825

Car insurance rates for adults in Idaho

On average, an adult male driver in Idaho pays $1,918 a year for full coverage or $160 per month. Women pay $1,868 a year or $156 per month for the same coverage. Compared to teens who are just starting out and seniors who may have slower reaction times, adults are seen as less risky to insure, which is why their rates are typically lower.

However, exact rates can vary widely from driver to driver, so it’s helpful to compare quotes to find the best price for your vehicle.

25$2,415$2,216

Car insurance rates for senior drivers in Idaho

If you’re a senior driver, your car insurance costs go up as you age, as insurers see older drivers as higher risk due to factors like slower reaction times and vision changes, which can increase the chance of an accident.

At age 65, men pay about $1,762 per year, while women pay $1,742. But by age 70, average annual premiums rise to $1,883 for men and $1,810 for women. At 75, rates increase even further – $2,151 for male drivers and $2,055 for female drivers.

Despite rates going up for seniors, you can still keep costs down by maintaining a clean driving record and taking advantage of senior discounts.

Methodology

To determine average premiums, Insure.com commissioned Quadrant Information Services for 2026 car insurance data. Our team of data analysts and editors analyzed quotes from 195 insurance companies across 34,595 ZIP codes.

Rates are based on a sample profile of 40-year-old male and female drivers driving a Honda Accord LX with a clean driving record and a good insurance score. We gathered quotes across three coverage levels:

  • Full coverage: limits of $100,000 per person for bodily injury, $300,000 per accident, and $100,000 for property damage per accident.
  • State minimum: the lowest coverage your state legally allows.
  • Liability only: limits of $50,000 per person for bodily injury, $100,000 per accident, and $100,000 for property damage per accident.

Additionally, we collected average rates for drivers across four age groups:

  • Teen drivers (16-19)
  • Young drivers (20-24)
  • Adult drivers (25-26)
  • Senior drivers (65-75)

To compare costs across vehicles, we also analyzed rates for 1,549 make and model combinations, based on a 40-year-old male driver with the same coverage level (100/300/100 limits with a $500 collision/comprehensive deductible), a 12-mile commute, and 10,000 annual mileage.

The national average comes to $2,578. These rates are for comparison purposes, and your own rates may vary.
