According to the Montana Code Annotated, all drivers are required to carry minimum liability insurance coverage to protect against financial loss in the event of an at-fault accident. This insurance provides specified limits for bodily injury and property damage. Failure to maintain continuous proof of insurance can result in severe consequences, including significant fines, possible jail time, and suspension of vehicle registration and license plates for repeat offenders. This guide details the required coverage limits, explains how the Montana Insurance Verification System works, and outlines the post-accident protocol, including the mandate to report crashes exceeding a certain damage threshold. Finally, you will learn how the state’s modified comparative negligence system determines the percentage of fault and proportionally reduces the damages you can recover.
