How much does your vehicle model affect car insurance rates in Montana?

A full coverage car insurance policy in Montana for a Honda Accord LX costs $2,502 annually, whereas a Honda CR-V costs $2,093 to insure in Montana – a difference of $409.

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

In Montana, as in most states, your car’s model year can impact your insurance rate. For example, the average annual premium for a 2023 Honda Accord LX is $2,872, compared to $2,535 for the 2024 model.

Quick tip: Know your state’s minimum insurance requirements before you buy

Car insurance requirements vary by state. In Montana, you must have at least the minimum liability coverage to drive legally. This typically includes:

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

These limits are just the minimum required by law-many drivers opt for higher coverage to ensure better financial protection after an accident. Driving without the required coverage in Montana can result in fines, license suspension or 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

Your car’s trim level plays a big role in determining your insurance premium. Insurers consider the vehicle’s value, repair costs, safety features and theft risk when setting rates. Higher trims with upgraded technology or powerful engines often have higher premiums since they’re more expensive to repair or replace.

For example, a 2023 Honda Accord LX costs $2,872 per year to insure in Montana, whereas the EX-L trim costs $2,434, a difference of $438 annually.

Trims that include luxury upgrades, like a premium sound system, often cost more to insure because they raise the vehicle’s overall value. Similarly, performance-focused trims with larger engines may increase premiums due to a greater risk of accidents or speeding.

The average annual premium for a full coverage car insurance policy in Montana is $2,541 or $212 per month. However, your actual premium may differ depending on your chosen coverage level.
