Montana Auto Insurance Requirements

Montana state flag waving against a vibrant sunset sky, featuring the state seal with a landscape and the word "Montana" above it.

Because insurance laws vary by state, it’s important to understand Montana’s specific requirements. Before you can drive legally in Montana, you must have a valid driver’s license, and your vehicle must have current registration and meet the state’s insurance requirements.

Here’s an overview of Montana’s auto insurance requirements:

Other coverages, such as uninsured motorist coverage, are optional but may be worth it due to the extra protections they provide. The good news is that Montana uses an insurance verification system to electronically confirm proof of insurance, reducing the number of uninsured drivers on the road.

Is minimum coverage enough in Montana?

Montana’s minimum auto insurance requirements provide the basic coverage you need and can help protect you against financial burdens following an accident. But it may be insufficient following a serious accident.

That’s why most experts advise purchasing higher coverage amounts to better protect your assets. One serious accident can quickly exhaust coverage limits, leaving you on the hook for the remaining balance.

For example, a multi-vehicle collision causing significant injuries could easily exceed the $50,000 bodily injury limit, leaving you personally responsible for any additional costs. And the cost to replace newer vehicle models could quickly surpass the $20,000 property damage limit. 

Montana has a three-year statute of limitations for filing personal injury claims after a car accident.[10]
