Montana’s Minimum Car Insurance, Explained in Plain English
Key Takeaways: Montana’s 25/50/20 rule, set by § 61-6-103, MCA, requires $25,000 in bodily injury coverage per person, $50,000 per accident when multiple people are hurt, and $20,000 for property damage. These are per-accident minimums, and insurers cannot issue reduced limits endorsements below them. A compliant policy must cover the named insured and anyone driving with permission. Because minimum limits are often exhausted quickly, uninsured motorist coverage, which must be offered unless rejected in writing, can be critical. Montana requires drivers to carry proof of insurance, with misdemeanor penalties for driving uninsured.
Montana law requires every driver to carry at least $25,000 in bodily injury coverage for one person hurt in a crash, $50,000 per accident when two or more people are hurt, and $20,000 for property damage. Those figures come from § 61-6-103, MCA. The tricky part isn’t the math, it’s what happens when the at-fault driver only carried the bare minimum and your medical bills blow past it in the first week.

What the Montana 61-6-103 Minimum Liability Limits Actually Require
The statute breaks the required coverage into three separate buckets. Under § 61-6-103(1)(b), MCA, a compliant policy must pay at least $25,000 for bodily injury to or death of one person in any accident, $50,000 for bodily injury to or death of two or more persons in any accident, and $20,000 for injury to or destruction of property in any accident. These are per-accident numbers, not annual totals. Note that the $50,000 figure is the total available for everyone injured in a single crash, and any one person’s recovery is generally capped at the $25,000 per-person limit.
The law also spells out who and what the policy must cover. Section 61-6-103(1)(a)-(b), MCA requires the policy to designate all motor vehicles covered and insure the named policyholder along with any person using the vehicle with express or implied permission. Coverage extends to liability arising from ownership, maintenance, or use of that vehicle within the United States or Canada. Your neighbor who borrowed your truck may be covered under your policy, subject to policy terms and enforceable exclusions.
25/50/20 Montana at a Glance
| Coverage Type | Statutory Minimum | What It Pays For |
|---|---|---|
| Bodily injury, one person | $25,000 | Injuries or death of a single person in one accident |
| Bodily injury, two or more people | $50,000 | Total available for all injured people in one accident |
| Property damage liability | $20,000 | Damage to vehicles or other property of others |
These limits are a floor, not negotiable. Section 61-6-103(12), MCA prohibits insurers from issuing reduced limits endorsements below these minimums. A Montana insurer cannot sell a policy below 25/50/20, though whether a particular claim is covered depends on policy language and crash facts.
Why State Minimum Coverage Often Isn’t Enough
Here’s the practical reality: $25,000 doesn’t go far. An ambulance ride, emergency room visit, imaging, and short hospital stay can exhaust that number before your first follow-up appointment. Add surgery, physical therapy, or time off work, and the at-fault driver’s minimum policy may be gone while bills keep arriving.
When the liable driver’s limits run out, your practical options narrow. You may pursue the at-fault driver personally for damages above policy limits, though collecting from someone who could only afford minimum coverage is often difficult and judgments frequently prove uncollectible. This is why understanding what car insurance covers before a crash matters.
Uninsured and Underinsured Motorist Coverage Fills the Gap
Montana law requires insurers to offer uninsured motorist coverage. Under § 33-23-201, MCA, an auto liability policy issued in Montana must include uninsured motorist coverage in the bodily injury limits set by § 61-6-103, MCA, unless the insured rejects it in writing. The Montana State Auditor’s office confirms this: unless you sign a rejection form, your agent must generally provide it. Underinsured motorist coverage is separate and worth asking for by name. Many Montanans sign rejection forms without understanding what they gave up.
If you carried UM or UIM coverage, your own policy may step in when the other driver had nothing or too little. These claims are filed against your own insurer. Coverage availability, offsets, and whether you must exhaust the at-fault driver’s limits first depend on your specific policy terms, so reviewing your declarations page early is smart.
💡 Pro Tip: Ask your agent in writing what your UM/UIM limits are and whether they stack across vehicles on the policy. That single question can change the value of a future claim more than almost anything else you do.
Proof of Insurance Montana Drivers Must Carry
Montana treats liability insurance as a condition of driving, not optional. The state’s insurance regulator states every Montana driver is required to carry liability insurance on their vehicle. If a vehicle is registered and operated on public roads, it must be covered by minimum liability insurance, and the driver must carry proof and produce it when law enforcement asks. Review the state’s guidance on Montana auto insurance requirements for the regulator’s summary.
Driving uninsured carries misdemeanor penalties. Under § 61-6-304, MCA, a first conviction carries a $250, $500 fine; a second conviction carries a $350 fine; and a third or subsequent conviction carries a $500 fine, up to 10 days in county jail, or both. On a second or subsequent conviction, the court must order surrender of the vehicle’s registration receipt and license plates. Upon proof of compliance with § 61-6-301 and payment of required fees, the department shall issue a restricted registration receipt to the offender during the 90-day suspension period following a second conviction, or during the 180-day suspension period following a third or subsequent conviction, limiting vehicle use to employment purposes only. These criminal penalties don’t compensate you for injuries, and a citation doesn’t establish civil liability.
Where the Insurance Rules Live in Montana Law
The framework sits in Title 61, chapter 6, MCA, which covers motor vehicle insurance responsibility and verification. Section 61-6-103, MCA sets policy minimums, § 61-6-301 and § 61-6-302, MCA impose the duty to carry and show proof of coverage, and related provisions address enforcement. The full text of the motor vehicle liability policy statute is publicly available.
What Insurance Adjusters Do With Minimum-Limits Claims
When only 25/50/20 is available, adjusters often move quickly with an early offer, and quick is not the same as generous. An offer that arrives before you’ve finished treating is often made before anyone knows what your injuries are actually worth.
Before you sign anything, consider:
- Whether you’ve reached maximum medical improvement or more treatment is likely
- Whether other coverage exists, including UM/UIM, med-pay, or a second liable party
- Whether lost wages and future earning capacity have been documented
- Whether the release closes out claims you haven’t discovered yet
Releases are typically final. Once you sign, reopening the claim is generally difficult. Narrow grounds such as fraud, mutual mistake, or duress are fact-specific and hard to establish.
💡 Pro Tip: Ask the at-fault driver’s insurer to confirm the policy limits in writing. Montana insurers will often disclose limits on request, and knowing that number early can tell you whether this is a policy-limits case or something bigger.
When It Makes Sense to Talk With a Lawyer
Many Montanans don’t think about calling an attorney after a crash, especially when the other driver’s insurer seems cooperative. But if you’re facing bills that exceed available coverage, a disputed fault determination, or an evolving injury, that’s when guidance matters. Our team handles montana 61-6-103 minimum liability limits lawyer matters across the state.
We’re also one of the few Montana firms that handles both auto injury claims and workers’ compensation. That matters when you’re hurt in a crash while on the job, because both systems can be in play. If a workers’ compensation insurer asserts a subrogation lien against a third-party recovery under § 39-71-414, MCA, Montana’s made-whole doctrine may limit that lien: the insurer’s subrogation right generally doesn’t arise until the injured worker has been fully made whole, and whether that has happened is a fact question.
Frequently Asked Questions
1. Does Montana require more than 25/50/20 coverage?
No. The Montana 61-6-103 minimum liability limits set the floor at $25,000 per person for bodily injury, $50,000 per accident, and $20,000 for property damage. You can purchase higher limits, and many drivers do, but the statute doesn’t require it.
2. What happens if the at-fault driver’s coverage doesn’t cover my bills?
Your own underinsured motorist coverage may apply, if you carried it, subject to your policy’s terms. You may pursue the at-fault driver personally for the excess, though collecting from someone with limited assets is often impractical.
3. Am I covered if someone else was driving my car?
Generally yes. Section 61-6-103(1)(b), MCA requires a compliant policy to insure the named insured and any person using the vehicle with express or implied permission. Individual policies can contain exclusions, so the actual answer depends on your policy language.
4. Do I have to show proof of insurance to law enforcement?
Yes. Montana law requires drivers to carry proof of insurance and produce it when requested. Failing to produce proof can result in a citation, though courts often dismiss the charge if you show valid coverage was in effect on the date of the stop.
5. Can an insurer sell me a policy below the state minimum?
Generally no. Section 61-6-103(12), MCA states that a reduced limits endorsement may not be issued to a policy issued in compliance with the section. The minimums function as a legal floor.
The Bottom Line for Montana Drivers
Montana’s 25/50/20 requirement gives every driver a baseline of financial responsibility, and § 61-6-103, MCA sets it. What the statute doesn’t do is guarantee that available money will match what a serious injury actually costs. Understanding the Montana 61-6-103 minimum liability limits, checking your own UM/UIM coverage, and being cautious with early settlement offers are three practical steps that may strengthen your position.
