Minimum car insurance requirements in Wisconsin

If you drive in Wisconsin, the state expects you to be insured before you ever turn the key. Since November 2011, every motor vehicle operated on a Wisconsin highway has to be covered by a liability policy, and the person behind the wheel has to keep proof of that coverage in the car.¹ Wisconsin is an at-fault state, so the driver who causes a crash, and that driver's insurer, pays for the harm. The numbers below are the legal floor. They are not a statement about what actually protects you if you get hurt.

What Wisconsin actually requires

Two coverages are mandatory here, and the second one surprises people. The first is liability insurance, which pays other people when you cause the wreck. The second is uninsured motorist coverage, usually written UM, which pays you when the at-fault driver has no insurance at all.² Plenty of states require only liability. Wisconsin requires both, and the UM piece cannot be rejected.

Everything else is optional. Underinsured motorist coverage, medical payments coverage, collision, and comprehensive are all things you can add or decline. Your insurer has to offer some of them, but the choice is yours.

The liability minimums: 25/50/10

Wisconsin's minimum liability limits live in Wis. Stat. § 344.33(2):³

• $25,000 for bodily injury or death of one person in a single crash
• $50,000 for bodily injury or death of two or more people in a single crash
• $10,000 for damage to someone else's property

Agents compress this to "25/50/10." Those three numbers are the most another person can collect from your policy if you are at fault, no matter how badly they are hurt or how much their car is worth. A single ER visit and a few days of missed work can blow past $25,000. A newer vehicle can total out well above the $10,000 property cap, which is one reason a damaged-but-repaired car can leave you chasing a diminished value claim on top of the repair bill. When the harm is larger than the policy, the coverage does not grow to meet it. The injured person is left going after the at-fault driver personally, which is often a dead end, or turning to their own coverage.

Uninsured motorist coverage is mandatory too

Wisconsin drivers also have to carry uninsured motorist bodily injury coverage of at least $25,000 per person and $50,000 per accident.² This is the coverage that steps in when the person who hit you carries no insurance, or when a hit-and-run driver is never identified. Because it is required and cannot be waived, it is the one piece of your own policy most likely to matter after a crash with an uninsured driver. Given that Wisconsin never checks for insurance at registration, uninsured drivers are a real presence on the road, and your UM coverage is what fills that gap.

What is offered but optional

Two coverages sit in a middle zone: your insurer must put them in front of you, but you can turn them down.

Underinsured motorist coverage, or UIM, pays the gap when the at-fault driver has some insurance but not enough. The insurer has to give you written notice that UIM is available, one time, when the policy is delivered. If you accept it, the minimum is $50,000 per person and $100,000 per accident. If no premium is ever charged for it, the law treats that as conclusive proof you rejected the coverage, so it is easy to end up without it by simply never opting in.²

Medical payments coverage, or MedPay, covers medical bills for you and your passengers regardless of fault, starting at $1,000 per person. You can reject it. Once you do, your insurer does not have to keep offering it on renewals unless you ask for it again in writing.²

Wisconsin has no personal injury protection, or PIP. If you skip MedPay and get hurt, your own health insurance and the at-fault driver's liability coverage are usually where your bills land.

Why these numbers changed, and why the floor is low

The current minimums are the product of a policy reversal. Before November 1, 2011, Wisconsin briefly required higher liability limits, made underinsured motorist and medical payments coverage mandatory rather than optional, and let injured people stack coverage across multiple vehicles. 2011 Wisconsin Act 14 undid most of that.⁴ It lowered the liability floor back to 25/50/10, turned UIM and MedPay into optional coverages, ended mandatory stacking, and allowed insurers to write reducing clauses that shrink your UIM payout by amounts already paid by the at-fault driver's insurer or by worker's compensation.⁴ That last change matters. A $50,000 UIM limit can be worth far less in practice once those offsets apply, so the number on your declarations page is not always the number you collect.

Low minimums collide with a few other Wisconsin rules. The state uses modified comparative negligence with a 51 percent bar, so you can share some blame and still recover, but if you are found 51 percent or more at fault you collect nothing.⁵ You generally have three years from the date of the crash to file a personal injury lawsuit.⁶ And because there is no PIP and no damage cap on ordinary compensatory damages, an injured person often has to piece together recovery from the at-fault driver's thin liability policy plus their own UM or UIM coverage.

Proof of insurance and what happens if you skip it

You have to carry proof of insurance whenever you drive and show it if a traffic officer asks. Wisconsin accepts electronic proof, including an image on your phone, and an officer who looks at your phone for that purpose is not allowed to view anything else on the device.¹ An officer also cannot pull you over solely to check whether you are insured; the insurance question can only come up during a stop made for some other reason.⁷

The penalties sit in Wis. Stat. § 344.65. Operating without the required insurance carries a forfeiture of up to $500.⁷ Failing to have proof in the car is a much smaller $10 forfeiture, and you can avoid a conviction on that one by later producing valid proof to the court or the officer.⁷ Showing false or fraudulent proof of insurance is the serious one, with a forfeiture of up to $5,000.⁷ Wisconsin also does not require you to show proof of insurance when you get your license or register a vehicle, which is part of why uninsured drivers stay on the road.⁸

After a Wisconsin crash

If you have been hit, the at-fault driver's 25/50/10 policy is often smaller than the harm it is supposed to cover, which makes your own coverage and the details of the other driver's policy worth checking carefully. Get the crash report, document your injuries and your vehicle's value, and find out the actual policy limits on both sides before you accept any offer. Insurers are not going to volunteer that a UM or UIM claim on your own policy is available, so it pays to know what you bought. When the at-fault driver's limits are thin or fault is disputed, it is worth talking to an attorney who handles Wisconsin car crash cases.
