Understanding SR-22 Insurance in Montana

- DUI or DWI conviction
- Multiple traffic violations in a short period
- At-fault accident without insurance
- License suspension or revocation
- Conviction for driving without insurance

How DUI Affects Your Montana Insurance Rates
A DUI conviction has severe consequences for auto insurance in Montana:
- Rate Increase: Average increase of 60-100% for 3-5 years
- SR-22 Requirement: Mandatory filing for minimum 3 years
- Limited Options: Many standard insurers will not cover DUI drivers
- Long-term Impact: DUI stays on your record for 10 years in Montana
After a DUI, you’ll need to obtain coverage from high-risk or non-standard insurance providers. Rates gradually decrease as time passes without additional violations, but expect elevated premiums for several years.
