Wisconsin law requires every driver to carry auto liability insurance, but the minimum limits required by law are dangerously low. A single serious accident can easily exceed them — and when that happens, your personal assets are on the line.
Wisconsin's Minimum Auto Liability Requirements
Wisconsin's minimum required liability coverage, per Wis. Stat. § 344.01(2)(d), is:
- $25,000 per person for bodily injury
- $50,000 per accident for bodily injury
- $10,000 for property damage
This is often written as 25/50/10. These limits represent the maximum your insurer will pay for a covered claim. Any costs above these limits become your personal financial responsibility.
Why the Minimums Are Not Enough
Medical costs after a serious accident can be staggering. An emergency room visit, ambulance transport, surgery, hospitalization, and physical therapy for one seriously injured person can easily reach $100,000–$200,000 or more. A pedestrian or cyclist struck by a vehicle often faces even higher medical costs.
Consider what happens if you cause an accident that seriously injures one person and their medical bills reach $120,000:
- With 25/50/10 minimums: your insurer pays $25,000. You owe the remaining $95,000 personally.
- With 100/300/100 limits: your insurer pays the full $100,000. You owe nothing beyond your policy.
That gap — $95,000 — can result in a lawsuit, wage garnishment, or liens against your home or savings.
What Higher Limits Actually Protect
If you have assets worth protecting — a home, savings, retirement accounts, investments — those assets are exposed when your liability limits are exhausted. A judgment against you for an at-fault accident can be pursued through:
- Wage garnishment
- Bank account levies
- Liens on real property (your home)
- Future earnings in some cases
Driving with minimum limits when you have significant assets is one of the highest-risk financial decisions a person can make.
What We Typically Recommend
For most drivers in Wisconsin, we recommend bodily injury limits of at least:
- $100,000 per person / $300,000 per accident — a meaningful step up from minimums
- $250,000 per person / $500,000 per accident — solid protection for families with assets
Combine higher liability limits with an umbrella policy for the most comprehensive personal protection. A $1M umbrella typically costs $200–$400 per year and sits above your auto and home liability limits.
The Cost Difference Is Small
The premium difference between state minimum liability and genuinely protective limits is often $10–$30 per month — a fraction of the financial exposure you're avoiding. We run the exact comparison for your situation so you can see the trade-off clearly.

Frequently Asked Questions
What are Wisconsin's minimum auto liability limits?
$25,000 per person and $50,000 per accident for bodily injury, plus $10,000 for property damage — commonly written as 25/50/10, per Wis. Stat. § 344.01(2)(d). These are legal minimums, not a safe amount of coverage for most drivers.
What happens if my liability limits aren't enough to cover an accident I caused?
You become personally responsible for the difference. If a claim exceeds your policy limits, the injured party can pursue you directly — through wage garnishment, bank account levies, or a lien on your home — for whatever your insurance didn't cover.
How much more does it cost to carry higher liability limits than the state minimum?
Often surprisingly little — commonly $10–30 a month more than state minimums for a meaningful step up in protection. This is illustrative; we run the exact comparison for your specific policy.
What liability limits do you typically recommend?
For most drivers, at least $100,000 per person and $300,000 per accident. Families with more assets to protect often go higher — $250,000/$500,000 — paired with an umbrella policy for the most complete protection.
Can I combine higher auto liability limits with an umbrella policy?
Yes, and it's usually the most cost-effective way to get real protection. A $1 million umbrella typically costs $200–400 a year and sits above your auto and home liability limits once those are raised to qualifying levels.
