Car-insurance requirements in Montana (2026)
Montana requires 25/50/20 in the usual shorthand. It appears on almost every published list of states that ban gender in rating and should not: its unisex provision was amended so that it expressly permits sex and marital status in ratemaking outside a narrow set of health lines.

How old is this minimum?
Our committed statutory record for Montana does not carry the date its current limits took effect, so no real-terms restatement is shown. We will not deflate from a year we have not read in the statute or its enacting bill. The limits themselves are confirmed against primary text; only the commencement date is missing.
What the property-damage minimum leaves exposed
A $42,000 property-damage claim against Montana’s minimum of $20,000 leaves $22,000 above the limit. That difference is the at-fault driver’s own exposure. The claim figure is an illustration; the limit is the statute.
