Cheapest car insurance in Montana for 2025

Montana drivers are required to carry liability insurance on their vehicle. It’s worth noting that liability-only coverage only covers your responsibility to other drivers or pedestrians. You would have to cover any damages to your own vehicle if you are deemed at fault. USAA offers the cheapest minimum coverage for Montana drivers, although their insurance policies are only available to veterans, active military members and their respective families. Fortunately, according to our research, there are other carriers available to a broader group of people that also offer premiums below the state average.

Minimum coverage requirements for Montana drivers

Like most states, minimum insurance requirements to drive legally. Minimum coverage in Montana will be written as 25/50/20 on your insurance policy, which indicates you have the following liability limits:

• $25,000 per person for bodily injury
• $50,000 per accident for bodily injury
• $20,000 per accident for property damage

On average, minimum coverage in Montana costs $408 per year. Although minimum coverage is usually cheaper than full coverage, it does not provide physical damage coverage for your car. If you cause an accident, hit an animal or have your car stolen, minimum coverage will not cover the incident. You may also be held personally liable for injuries or property damage you cause that exceeds your coverage limits, which may make buying higher liability limits worth the extra cost.

Full coverage generally refers to car insurance that includes liability plus collision and comprehensive coverage. Unlike minimum coverage, this type of insurance will cover your own property damage and injuries. Full coverage policies often have you covered when the other driver is uninsured or you’re at fault but have serious damage to your own vehicle. In Montana, some of the cheapest companies with full coverage car insurance include USAA, State Farm and Progressive.
