Average cost of car insurance Montana

Full coverage insurance costs more than minimum liability insurance, but the extra cost is worth it for most drivers. That’s because minimum liability only pays for injuries or damage you cause to others, leaving you to cover repairs or replacement of your own car out of pocket. Full coverage, on the other hand, includes collision and comprehensive insurance, so your vehicle is protected in situations like accidents, theft, storms, or vandalism.

The average cost of full coverage car insurance in Montana is $28 more than the national average car insurance rates in the U.S.

We recommend that you carry at least coverage limits of 100/300/100 – that’s $100,000 in bodily injury coverage per person, $300,000 per accident, and $100,000 in property damage coverage. These limits provide a better safety net if you’re involved in a serious accident where costs could quickly exceed minimum requirements.

What is full coverage car insurance?

Full coverage car insurance includes bodily injury liability and property damage liability coverage, as well as comprehensive and collision coverage. Collision insurance covers your vehicle if it’s damaged or destroyed in an accident, while comprehensive insurance provides protection against damage that is caused by something other than collisions, such as hail or theft.

If you lease or finance your car in Montana, your lender may ask you to purchase collision and comprehensive insurance beyond the state-mandated liability coverage.

The bottom line on saving and staying protected

It’s natural to look for ways to lower your insurance costs, but cutting corners on coverage can leave you financially vulnerable after an accident.

Make sure you choose a policy that balances affordability with protection. Always compare quotes from at least three companies to find low-cost car insurance in Montana.

Methodology

Insure.com gathered data from Quadrant Information Services to get car insurance rates in Montana. The rates are based on a sample profile of a 40-year-old male and female driving a Honda Accord LX with a good insurance score and no violation on record for a full coverage insurance policy with limits 100/300/100 and $500 comprehensive and collision deductibles.

We analyzed 53,409,632 insurance quotes from 170 insurance companies across 34,588 ZIP codes nationwide.

To determine car insurance rates for high-risk drivers with a history of traffic violations, we used a sample profile of a 40-year-old male and female driver who own a Honda Accord LX.

We also used sample profiles of drivers from different age groups: Teen drivers (Age 16-19), young drivers (Age 20-24), adult drivers (Age 25-60) and senior drivers (Age 65-75)

We determined the premiums for a high-risk driver with the following incidents applied

1 At-fault property damage accident over $2K
1 At-fault property damage accident under $2K
At-fault bodily injury accident
Poor credit
DUI/DWI first offense
Speeding 30+ over limit
