Wisconsin is an at-fault (tort) state. Drivers must carry at least 25/50/10 in coverage, and the average full-coverage premium is $2,329 a year, 20% below the national average of $2,922. This guide covers what Wisconsin requires, what drivers pay, the rules on fault, uninsured drivers, penalties, teen drivers and phone use, and how to pay less.
| Minimum coverage | 25/50/10 |
| Fault system | At-fault (tort) |
| Average full coverage | $2,329 a year ($194 a month), 20% below the national average of $2,922 |
| Uninsured drivers | 15.6% (2023), the 16th highest rate of 51 |
| Filing after serious violations | SR-22 |
Wisconsin requires $25,000 bodily injury liability per person, $50,000 per accident, and $10,000 property damage liability (Wisconsin Office of the Commissioner of Insurance, "Frequently Asked Questions: Automobile Insurance").
| Uninsured motorist | At least $25,000 per person and $50,000 per accident for bodily injury. |
The minimums are a legal floor, not a recommendation. Property damage limits in particular don't go far when a new car can cost more than the limit to replace, and anything above your limits is your personal responsibility. See how limits and deductibles work and every type of coverage explained.
The average full-coverage premium in Wisconsin is $2,329 a year, 20% below the national average of $2,922. That makes Wisconsin the 16th cheapest of 49 (48 states plus D.C.; Alaska and Hawaii aren't in the data) (Experian, "Car Insurance Average Costs by State," published September 9, 2026; full coverage, 12 months to August 2026).
Within Wisconsin, prices still vary a lot by ZIP code, driving record and car, and 15.6% of drivers on Wisconsin roads were uninsured in 2023, so the coverage you choose matters as much as the premium.
Your own price depends on your ZIP code, age, driving record, car and coverage. Try our car insurance calculator with Wisconsin preselected for a personal estimate, and see what determines your car insurance cost.
Wisconsin uses modified comparative fault with a 51% bar: your damages are reduced by your share of the blame, and you recover nothing if you are more than 50% at fault. (Matthiesen, Wickert & Lehrer, "Contributory Negligence/Comparative Fault Laws in All 50 States," updated June 10, 2026)
An estimated 15.6% of Wisconsin drivers were uninsured in 2023, the 16th highest rate among the 50 states and D.C. (Insurance Research Council, uninsured motorist estimates for 2023, via Insurance Information Institute "Facts + Statistics: Uninsured motorists"). Uninsured and underinsured motorist coverage protects you when one of them hits you. See coverage types.
You must be able to show proof of insurance when a law enforcement officer asks for it. (Wisconsin Statutes §344.62)
Driving without the required insurance can bring a forfeiture of up to $500. If you're uninsured in a crash and don't meet the Safety Responsibility requirements, your license and/or vehicle registrations are suspended for one year. (Wisconsin Statutes §344.62; Wisconsin DMV, "Safety Responsibility law")
A conviction for driving uninsured also follows you into your next policy. In CarInsurance.com's rate analysis, it raised the average full-coverage premium in Wisconsin from $1,664 to $2,184 a year, an increase of 31% (CarInsurance.com, "Penalty for driving without insurance in every state," updated March 24, 2026; rate analysis).
Beyond the penalties, driving uninsured leaves you personally liable for any damage you cause. See what happens if you drive without car insurance.
To reinstate after a Safety Responsibility suspension, Wisconsin requires an SR-22 certificate, which must be kept for three years from the date you become eligible for reinstatement. (Wisconsin DMV, "Safety Responsibility law")
Wisconsin uses graduated driver licensing (Insurance Institute for Highway Safety, "Graduated licensing laws" table):
Adding a teen is usually the biggest single increase in a family's premium. Keeping them on the family policy, a good-student discount and a safe, modest car help most.
A distracted-driving ticket can count against your record and your premium. (Insurance Institute for Highway Safety, "Electronic device laws" table)
