Montana follows a “modified comparative negligence” theory. This means that individuals can recover compensation if they are less than 50% responsible for causing their own injuries. If an individual's fault for the situation exceeds 50%, they will not be able to recover compensation for their losses.
However, any person who shares fault below 50% will receive reduced compensation based on their overall percentage of fault. This comparative negligence theory could certainly play a role in a chain-reaction collision. Individuals who were partially responsible may be able to receive some relief through compensation, but this may not cover all of their expenses.
