Montana Car Insurance Requirements
Montana requires all drivers to carry liability insurance. The minimum coverage levels are:
- $25,000 bodily injury liability per person
- $50,000 bodily injury liability per accident
- $20,000 property damage liability per accident
This is commonly written as 25/50/20 liability.
No uninsured motorist requirement: Montana does NOT require uninsured motorist (UM) coverage, but experts strongly recommend adding it. About 8% of Montana drivers are uninsured. Without UM coverage, you're at risk if hit by an uninsured driver.
Montana is a tort state, meaning the at-fault driver is financially responsible for injuries and damages they cause.
Why You Should Add Uninsured Motorist Coverage
Although Montana doesn't require uninsured motorist (UM) coverage, it's one of the most important coverages you can buy:
About 8% of Montana drivers are uninsured. If one of them causes an accident, your UM coverage pays for your injuries and damages. Without UM, you'd have to sue the at-fault driver personally—and may never collect.
UM also covers hit-and-run accidents. If you're injured by a hit-and-run driver, your UM coverage pays.
Recommended UM limits: At least 100/300 to match standard liability coverage. The cost is modest—typically $50-$100/year—compared to the protection it provides. Also consider adding underinsured motorist (UIM) coverage for drivers who don't have enough insurance.
Average Car Insurance Costs in Montana
Montana drivers pay an average of $1,498 per year for full coverage car insurance, or about $125 per month. Minimum coverage in Montana averages around $512 per year.
Montana rates are slightly below the national average due to: low population density, fewer accidents per capita, less traffic congestion, and lower crime rates.
Rates vary by city and region:
City rate examples (average full coverage):
• Billings: $1,587/year (highest in Montana)
• Missoula: $1,512/year
• Great Falls: $1,456/year
• Bozeman: $1,489/year
• Butte: $1,398/year
Billings has the highest rates due to being Montana's largest city, but even Billings is affordable compared to most urban areas.
Wildlife Collisions and Comprehensive Coverage
Montana has one of the highest rates of wildlife collisions in the United States. Drivers commonly encounter:
- Deer (most common—thousands of collisions per year)
- Elk (large and dangerous)
- Moose (extremely dangerous—can total a vehicle and cause fatalities)
- Antelope
- Bears (rare but possible)
- Livestock (cattle, horses on open range)
Comprehensive coverage covers animal strikes. This is ESSENTIAL in Montana. A single moose collision can cause $20,000-$50,000+ in damage and total your vehicle.
Wildlife collision tips:
• Be extra alert at dawn and dusk (peak wildlife activity)
• Watch for wildlife warning signs
• Scan both sides of the road, not just straight ahead
• If you're about to hit a deer or elk, brake but don't swerve—maintain your lane
• If you hit a moose, DO NOT exit your vehicle—moose may attack
• File a comprehensive claim immediately
Open range law: Montana is an "open range" state, meaning livestock can roam freely in some areas. If you hit a cow or horse on an open range road, you may be liable. Comprehensive coverage protects you.
Rural Driving and Long Distances
Montana is the 4th largest state by area with a small population. Rural driving creates unique insurance considerations:
Long distances to help: Roadside assistance is critical in Montana where tow trucks may be 100+ miles away. Breaking down in -20°F weather can be life-threatening.
Harsh winters: Montana winters are severe. Comprehensive covers weather damage; collision covers ice-related accidents. Both are essential.
High-speed rural highways: Montana's speed limit is 80 mph in some areas. High-speed accidents cause more severe damage. Adequate liability coverage (100/300/100) is important.
Montana driving tip: Keep an emergency kit year-round: blankets, water, non-perishable food, flashlight, first aid kit, jumper cables, and a phone charger. In winter, add sand/kitty litter, ice scraper, and extra warm clothing. Cell coverage is spotty in rural areas—be prepared.
Montana Financial Responsibility Law
Montana law requires all drivers to maintain proof of financial responsibility. You must carry proof of insurance in your vehicle at all times. Acceptable proof includes:
- Physical insurance card
- Digital insurance card on your phone (Montana accepts electronic proof)
- Electronic policy document
Penalties for driving uninsured in Montana:
• $250-$500 fine for first offense, up to $1,000 for repeat offenses
• License suspension
• Vehicle registration suspension
• SR-22 requirement
• Possible jail time for repeat offenses
• Higher insurance rates when you reinstate coverage
SR-22 Insurance in Montana
An SR-22 is a certificate your insurer files with Montana Motor Vehicle Division proving you carry liability insurance. Montana requires SR-22 after:
- DUI or DWI conviction
- Driving without insurance
- Multiple at-fault accidents or serious violations
- License suspension or revocation
- Accumulating excessive points
The SR-22 filing fee is typically $15-$50, but your insurance rates will increase significantly—often by 50-100%+.
How long? Montana typically requires SR-22 for 3 years. You must maintain continuous coverage—any lapse triggers license suspension.
Coverage Options Beyond the Minimum
Consider adding these coverages beyond Montana's minimum:
Higher Liability Limits: Increase from 25/50/20 to 100/300/100 or higher. High-speed rural driving increases accident severity. Recommended: At least 100/300/100.
Uninsured/Underinsured Motorist (UM/UIM): NOT required but highly recommended. Recommended limits: Match your liability coverage (100/300).
Collision Coverage: Pays for damage to your car after an accident, regardless of fault. Recommended if: Your car is worth more than your deductible or you have a loan/lease.
Comprehensive Coverage: ESSENTIAL in Montana for wildlife collisions, weather damage, hail, and theft. Strongly recommended.
Rental Reimbursement: Covers rental car costs while your vehicle is repaired. Typical cost: $20-$40/year.
Roadside Assistance: Critical in rural Montana. Typical cost: $10-$30/year. Worth every penny.
