Wisconsin Minimum Auto Insurance Requirements: What Drivers Must Carry

Wisconsin law requires every driver to carry at least three types of auto insurance: bodily injury liability, property damage liability, and uninsured/underinsured motorist coverage. The state sets minimum dollar limits—$25,000 per person for bodily injury, $50,000 per accident, $10,000 for property damage, and $25,000 for uninsured/underinsured motorist bodily injury. These limits apply to all licensed drivers and vehicles registered in WI, regardless of age or vehicle type. Below is a detailed breakdown of each required coverage, why it matters, and how to meet or exceed the minimum legally.

Core Coverage Types Required by Wisconsin Law

Bodily Injury Liability (BI)

BI protects other people injured in an accident you cause. Wisconsin's minimum limits are:

• $25,000 per person
• $50,000 per accident (combined for all injured parties)

Property Damage Liability (PD)

PD covers repair or replacement of another driver's vehicle or other property you damage. Minimum limit: $10,000 per accident.

Uninsured/Underinsured Motorist (UM/UIM) Coverage

If you're hit by a driver without sufficient insurance, UM/UIM steps in. Wisconsin mandates a minimum of $25,000 per person for bodily injury.

Why These Minimums Matter

Driving without the required coverage can result in license suspension, vehicle registration hold, and hefty fines. Moreover, the minimum limits often fall short of covering serious injuries or extensive property damage, leaving drivers financially exposed.

How to Verify Your Policy Meets State Minimums

• Review the declarations page of your policy; it lists each coverage limit.
• Contact your insurer to confirm the policy includes UM/UIM coverage, which some carriers offer as an optional add‑on.
• Check the Wisconsin Department of Transportation (DOT) website for any updates to statutory limits.

Choosing Coverage Above the Minimum

While the law sets the floor, most drivers opt for higher limits to protect assets. Common upgrade patterns include:

• BI: $50,000/$100,000
• PD: $25,000 or higher
• UM/UIM: $50,000 per person

Higher limits reduce out‑of‑pocket risk if you're liable for severe injuries or a total loss.

Special Situations and Exceptions

Teen Drivers

Teenagers must meet the same state minimums, but many parents add an extra $10,000–$20,000 of liability for added protection.

Non‑Owner Carriers and Rental Vehicles

Rental agencies in Wisconsin typically include the required liability limits in the rental agreement, but verify UM/UIM coverage before signing.

Frequently Asked Questions

Do I need collision or comprehensive coverage in Wisconsin?

No, these are optional. They cover damage to your own vehicle from accidents (collision) or non‑collision events (comprehensive) and are not required by law.

Can I use a non‑resident's insurance policy while driving in Wisconsin?

Only if the policy meets or exceeds Wisconsin's minimum limits and is recognized by the state's insurance regulator.

What happens if I'm involved in an accident with an underinsured driver?

Your UM/UIM coverage will pay up to the policy limit for your injuries after the at‑fault driver's insurance is exhausted.
