How Montana Law Affects Your Car Accident Case

Under Montana's modified comparative fault system, motor vehicle accident claimants can recover as long as their fault does not exceed 50%. Your damages are reduced by your fault percentage, and the critical question in every Montana car accident case is whether the at-fault driver bears the majority of responsibility.

The statute of limitations for this type of claim in Montana is 3 years — in line with the national average of 2.7 years. This is a standard timeframe, but acting sooner preserves evidence and strengthens your position. Importantly, Montana recognizes a discovery rule, which can extend the filing window in cases where the harm was not immediately apparent.

Drivers in Montana must carry at least 25/50/20 in liability coverage — that’s $25K bodily injury per person, $50K per accident, and $20K property damage. While this meets the state minimum, a single ER visit can easily exceed these limits. The at-fault driver’s policy may not fully cover your losses in a serious accident.

Steps After a Car Accident in Montana

After a car accident in Montana, your immediate steps should include: documenting the scene with photos and video, exchanging insurance information with all parties, filing a police report, and seeking medical attention within 24–72 hours even if you feel fine — some injuries take days to manifest. You have 3 years to file a lawsuit, but evidence preservation and witness availability degrade over time.
