Does your vehicle model affect car insurance rates in Montana?

Your car’s make and model play a major role in determining your insurance rates, along with other factors insurers use when setting premiums.

For example, the average annual full coverage cost for a Honda Accord LX in Montana is $2,502, while the average premium for a Honda CR-V is $2,093 – that’s a difference of $409 annually.

Does your car’s model year affect insurance rates in Montana?

In Montana – as in many other states – a car’s model year can impact your insurance rates. For instance, the annual premium for a 2023 Honda Accord LX is around $2,872, while insuring the 2024 model costs $2,535.

Quick tip: Check your state’s minimum coverage rules

Every state sets its own minimum car insurance requirements, and Montana is no exception. To drive legally, you’ll need at least the minimum liability coverage, which typically includes:

  • Bodily injury liability per person and per accident
  • Property damage liability

These limits are the bare minimum – many drivers choose higher coverage to better protect themselves financially after an accident. Not carrying the required coverage in Montana can lead to fines, license suspension and even vehicle impoundment.

Auto insurance premiums vary significantly from city to city, so drivers need to be sure they’re getting the best deal. Insure.com has done the research for you. Get more information on auto insurance rates by city below.

How your car’s trim affects insurance rates in Montana

In Montana, insurance premiums vary depending on your vehicle’s trim. Higher trims with upgraded technology or more powerful engines are often more expensive to insure because of their costly replacement and repair costs.

For instance, full coverage car insurance for a 2023 Honda Accord LX in Montana costs $2,872 per year. On the other hand, the Honda Accord EX-L trim costs $2,434 annually to insure – a difference of $438.

Luxury features such as premium audio systems can increase a vehicle’s value, leading to higher premiums. Similarly, performance trims with larger engines may raise insurance premiums due to the higher risk of accidents or speeding.
