Montana’s 25/50/20 Rule: What It Covers
Montana law requires drivers to carry liability coverage. This part of your policy pays for injuries and damage you cause to others in a crash.
- $25,000 for injuries to one person. This pays for medical bills if you hurt someone in a crash.
- $50,000 for injuries to more than one person in a single crash. This is the total amount your insurance will pay for all injured people combined.
- $20,000 for property damage. This pays to fix or replace what you damage, like another car, a fence, or a building.
Montana also requires coverage for injuries caused by uninsured drivers. This helps protect you if the other driver has no insurance.
MFP Tip: Wildlife collisions can cause major damage. Higher property damage limits can help protect you after a crash.
Montana New Car Insurance Costs
Your new car insurance price depends on the value of your car, how much coverage you choose, and your credit history. New cars often cost more to insure because repairs and replacement parts are more expensive.

Montana Used Car Insurance Costs
Used cars in Montana may cost less to insure, but dropping coverage for your own car can leave you paying out of pocket after a crash, a theft, or storm damage.
| Car Value | Coverage | 750+ (Excellent) |
700–749 (Good) |
650–699 (Fair) |
600–649 (Below Fair) |
|---|---|---|---|---|---|
| Under $15K | Full | $106 | $125 | $134 | $240 |
| Standard | $89 | $105 | $113 | $201 | |
| Liability only | $61 | $71 | $77 | $137 | |
| $15K–$25K | Full | $128 | $150 | $161 | $288 |
| Standard | $106 | $125 | $134 | $240 | |
| Liability only | $70 | $83 | $89 | $159 | |
| $25K–$40K | Full | $145 | $170 | $183 | $326 |

| Standard | $138 | $162 | $174 | $311 | |
| Liability only | $84 | $99 | $106 | $189 |
Most insurers group policies into three coverage levels:
- Full: Includes liability plus coverage for damage to your own car, even if you cause the crash or weather damages your vehicle.
- Standard: Higher liability limits than the state minimum, with or without coverage for your own car.
- Liability Only: Covers injuries and damage you cause to others, but not your own car.
How Credit History Influences Montana Car Insurance Prices
In Montana, insurers can use your credit history when setting your price. Drivers with strong credit often pay less, while drivers with below-fair credit usually pay much more for the same coverage.
In many cases, a driver with weak credit can pay 50 to 65 percent more than a driver with excellent credit, even if both have similar cars and clean driving records.
MFP Tip: If your credit improves, request a new quote before your renewal date. A better credit history can lead to a lower bill.
Find the Right Coverage
If you finance or lease a new car, your lender will require coverage that pays to repair or replace your car after a crash or storm. This protects their investment until the loan is paid off.
Gap insurance can help during the early years of a loan. If your car is totaled, it covers the difference between what your car is worth and what you still owe.
For used cars, the 10 percent test can guide your choice. If your yearly coverage cost is more than 10 percent of your car’s value, you may want to keep only liability and drop coverage for your own car.
Why Montana’s Minimums Can Leave You Paying Up
When You Damage Someone’s Property
Many vehicles on Montana roads cost more than $20,000 to repair. If your limit runs out, the rest of the bill can fall on you.
If You Injure Someone
Medical care and missed work can push costs past $25,000 for a single person. If more than one person is hurt, the $50,000 total limit has to cover everyone.
When an Uninsured Driver Hits You
Coverage for injuries and damage to your own car can help when the other driver cannot pay.
What Shapes Montana Rates
Montana uses an at-fault system. The driver who causes the crash is responsible for injuries and damage, which makes strong liability limits more valuable.
Snow, ice, and wildlife crossings can damage vehicles and lead to claims across the state.
Traffic around Billings, Missoula, and major routes like I-90 and I-15 raises the chance of minor crashes and repair costs.
How Montana Drivers Can Bring Their Insurance Costs Down
- Bundle policies. Putting home or renters insurance with the same company can lead to lower prices.
- Take a defensive driving course. Some insurers offer discounts for approved classes.
- Use safe-driver tracking programs. These track how you drive and can lower your rate if you avoid hard braking and late-night trips.
- Compare quotes. Prices can vary widely between companies for the same driver and car.
- Raise your deductible. This is the amount you pay out of pocket before insurance kicks in.
MFP Tip: If you drive long rural routes, ask about low-mileage discounts. Some insurers offer lower rates for drivers who spend less time on the road.
What to Do After Buying a Car in Montana
You need insurance in place before you can register your vehicle. Dealers often submit paperwork for new cars, while private sales leave the steps to you.
Registration and title work go through the Montana Motor Vehicle Division. New residents and in-state buyers have a short window to complete the process.
Review your coverage once a year. As your car’s value drops, you may be able to adjust your policy and lower your costs.
End Note
Meeting the legal minimum keeps you driving, but wildlife, winter conditions, and long distances can lead to bills that go beyond those limits.
Match your coverage to what you own and what a real crash can cost in Montana, not just what the law requires.
