How to save money on car insurance in Montana
If you're researching ways to save money on your car insurance premiums, these tips may help:
- Complete a driving course: In Montana, drivers who are 55 and older can take a qualifying driving course and get a discount on their policies.
- Call or email your agent: Contact your agent and explain that you're looking for ways to reduce your premiums. You may find that you're eligible for discounts you didn't know about, such as vehicle safety, accident-free, and multi-policy discounts.
- Sign up for usage-based insurance: Usage-based or pay-per-mile policies can be affordable alternatives to traditional car insurance. These policies base your premiums on your actual driving habits and the number of miles you typically drive. You could save money if you drive fewer miles than other drivers and maintain safe speeds. Several insurers in Montana offer pay-per-mile insurance, including Progressive, Root, and State Farm.
- Get quotes from other companies: When it comes to car insurance, doing some extra homework can pay off. Request quotes from multiple insurers to find the best car insurance rates for the coverage you need.
