Cheap quotes make minimum-coverage insurance an attractive choice. However, minimum coverage has low liability limits and no comprehensive or collision coverage. That means you won't have any protection for your own car, and will usually end up paying more if you cause an accident.

We recommend most drivers buy a full coverage auto insurance policy rather than a minimum coverage policy. This is especially true for drivers with a car less than 10 years old or worth more than $3,000.

Montana insurance laws: Minimum coverage requirements

Montana requires drivers to purchase a minimum amount of bodily injury and property damage liability insurance coverage, which is sometimes written as 25/50/20.

Coverage
Limit
Bodily injury (BI)$25,000 per person and $50,000 per accident
Property damage (PD)$20,000 per accident

Montana doesn’t require uninsured motorist coverage. However, insurance companies are required to offer it as part of liability coverage. Drivers have the option of declining uninsured motorist coverage.

While these limits fulfill the minimum amount of insurance coverage you can legally have, most drivers should consider a more comprehensive policy. That's because minimum coverage in Montana doesn't include any protection for your own car, or injuries to you and your passengers. Additionally, low liability limits mean you may have to pay out of pocket if you cause a serious accident.
