How to save on car insurance in Montana

While Montana car insurance rates are lower than other states, you can typically find extra savings in a few ways.

  • Driving school: Points from moving violations remain on your record for three years in Montana, potentially affecting your car insurance rates for that period of time or longer. The state does not automatically allow you to attend traffic school in exchange for a points reduction. But you could attend court for the ticket and request traffic school authorization from the judge.
  • Shop around for car insurance: As shown in the table above, the same level of car insurance in Montana could vary in price over $1,000 by providers. Getting multiple car insurance quotes to compare is vital to finding the lowest premiums. Fortunately, nearly every carrier has a short, easy online quoting tool available to help you round up the information you need in just a few minutes.
  • Look for discounts: Car insurance companies offer a few discounts to policyholders that could potentially help you save on coverage. These range from college and youth discounts to low-mileage or safety equipment discounts. For younger drivers facing higher rates, this can be particularly helpful if they qualify for the discounts.
  • Raise your deductible: If you are a safe driver with no traffic accidents or claims, you could consider raising your deductible since you are less likely to face an accident or claim. Although raising your deductible could save you money on your premium, experts recommend you only do so if you are able to afford the higher amount in the event of a claim.
