8% of drivers in Montana have no insurance at all. If one of them hits you, uninsured/underinsured motorist coverage (UM/UIM) pays for your injuries and vehicle damage. It's one of the most important coverages you can add — and one of the cheapest, typically adding just $10-$25/month.
(888) 217-6781Imagine you're stopped at a red light and an uninsured driver rear-ends you. Without UM/UIM coverage, you could be stuck paying your own medical bills and car repairs — even though you did nothing wrong. In Montana, with 8% uninsured drivers, this scenario is far too common.
Montana uses an at-fault system, meaning the at-fault driver pays for damages — but if they have no insurance, UM/UIM is your backup. While requirements vary, adding UM/UIM to your Montana policy is one of the smartest insurance decisions you can make.
