Minimum Coverage Requirements in Wisconsin
Wisconsin requires minimum liability coverage of 25/50/10: $25,000 bodily injury per person, $50,000 bodily injury per accident, and $10,000 property damage. Drivers convicted of OWI, operating after revocation, accumulating excessive points, or causing accidents while uninsured must file SR-22 proof of financial responsibility. The Wisconsin Department of Transportation monitors SR-22 compliance for the entire filing period, typically 3 years from reinstatement.
How Much Does Car Insurance Cost in Wisconsin?
Wisconsin high-risk auto insurance premiums depend heavily on violation type, time since offense, and filing history. OWI convictions carry the steepest surcharges—drivers typically pay $200–$400/mo for minimum SR-22 coverage, compared to $80–$120/mo for clean records. Rates decline gradually as violations age off: expect 30%–40% reductions after 3 years violation-free, with full standard rates possible 5–7 years post-OWI.
What Affects Your Rate
- Violation type: OWI convictions add 150%–250% surcharges; at-fault accidents add 50%–100%; license suspensions add 40%–80%
- Time since violation: surcharges decrease 10%–15% annually after year 2, with steeper drops after year 5
- Filing history: a second SR-22 requirement within 10 years triggers non-renewal from many carriers and forces assigned risk plans
- Credit-based insurance score: Wisconsin allows credit scoring for insurance, which compounds penalties for high-risk drivers with poor credit
- County: Milwaukee County SR-22 rates average 15%–25% higher than rural counties due to claim frequency and uninsured driver density
- Vehicle type: older vehicles (>10 years) allow liability-only SR-22 and lower premiums; financed newer vehicles require full coverage and significantly higher costs
