How to Find the Cheapest Car Insurance Rates in Montana

  1. Compare rates: It’s a good idea to get a quote from at least three different companies when looking for a new auto insurance policy, since rates can vary greatly from one provider to another. The cheapest for you may differ from the average.
  2. Keep your record clean: Drive safely and do your best to keep violations off your record to maintain low rates — speeding tickets, DUIs, etc., will all cause your premium to increase.
  3. Bundle policies: Most insurers offer a discount — sometimes up to 25% — for purchasing more than one type of policy, including home or renters insurance. Depending on the provider, you may be able to bundle other policies, such as pet and motorcycle insurance.
  4. Lower your coverage: As long as you have limits above Montana’s minimum coverage requirements, you can lower them if you wish. However, be aware that this leaves you at risk of significant out-of-pocket costs in the event of a claim. Make sure to weigh your situation and needs before deciding to lower your coverage.

Minimum Car Insurance Requirements in Montana

By law, Montana drivers must have an auto insurance policy that meets at least the following minimum requirements:

  • Bodily injury liability: $25,000 per person/$50,000 per accident
  • Property damage liability: $20,000 per accident

These liability limits only cover injuries and damage you cause to others in an accident, and will not pay for damage to your own vehicle. To add this to your policy, you’ll need full coverage, which includes comprehensive and collision coverages. It’s also a good idea to get more than the minimum liability limits if you can afford to for more robust financial protection.
