For the Wisconsin Personal Lines exam, the Personal Auto Policy (PAP) is tested two ways: the national policy structure and the Wisconsin auto laws layered on top of it. This standalone guide walks through the lettered parts every PAP uses, then focuses on the Wisconsin rules an agent applies every day—financial-responsibility minimums, the at-fault legal system, the mandatory uninsured-motorist requirement, and how policies can be cancelled or nonrenewed. Spend your study time on the Wisconsin overlay; that is where the state questions live.

The national fundamentals (quick version)

The Personal Auto Policy insures individuals and families for the vehicles they own and drive. It is divided into clearly labeled parts:

• Part A — Liability Coverage: pays for bodily injury (BI) and property damage (PD) the insured is legally responsible for, and includes a duty to defend with defense costs paid on top of the limit.
• Part B — Medical Payments: pays medical and funeral expenses for the insured and passengers regardless of fault.
• Part C — Uninsured/Underinsured Motorists (UM/UIM): pays your injuries when the at-fault driver has no insurance or too little.
• Part D — Coverage for Damage to Your Auto: Collision and Other Than Collision (Comprehensive), each with a deductible, paid at Actual Cash Value (ACV).
• Part E — Duties After an Accident or Loss and Part F — General Provisions set the rules.

An insured generally includes the named insured, the resident spouse, resident family members (including a child away at school), and anyone using the covered auto with permission. Eligible vehicles are private passenger autos, pickups, and vans not used primarily for business. That skeleton is the same nationwide; Wisconsin changes the dollar limits and the legal environment around it.

Wisconsin is an at-fault (tort) state

Wisconsin follows a tort (at-fault) system rather than a no-fault system. Whoever causes the crash is financially responsible, and the injured person recovers from that driver's liability insurance—or sues. Because of this, liability coverage and proof of financial responsibility are the backbone of Wisconsin auto regulation.

When both drivers share blame, Wisconsin uses modified comparative negligence, often called the 51% bar rule. Picture a simple cutoff: an injured person whose fault exceeds 50% recovers nothing at all. If their share is 50% or less, they can still collect, but the payout is trimmed by their own percentage of fault. This differs from a pure comparative system (where any at-fault claimant recovers something) and from a no-fault system (where each driver turns first to their own coverage). Verify the current statute, and watch the wording—exactly 50% still allows a reduced recovery, while 51% or more does not.

Financial responsibility: the 25/50/10 minimums

Wisconsin drivers must demonstrate financial responsibility, almost always by buying liability insurance that meets the state's minimum split limits commonly cited as 25/50/10:

• $25,000 bodily injury per person
• $50,000 bodily injury per accident
• $10,000 property damage per accident

Agents say this aloud as "25/50/10." Treat these as the commonly cited figures and verify the current statutory amounts. They are bare-minimum floors—most clients should buy more to protect their assets. An uninsured driver faces penalties, and although a bond or deposit can technically satisfy the law, auto liability insurance is the everyday method.

Mandatory uninsured motorist coverage

Here is a point Wisconsin agents must never get wrong: Uninsured Motorist (UM) bodily injury coverage is generally required on every Wisconsin auto policy, written at limits at least equal to the 25/50 bodily-injury minimums. UM protects you and your passengers when the at-fault driver carries no insurance or flees the scene (hit-and-run).

Unlike states where UM is merely "offered," Wisconsin builds it in as a mandatory coverage. An applicant cannot end up with a legal Wisconsin policy that has no UM.

Underinsured motorist coverage

Underinsured Motorist (UIM) handles the situation where the at-fault driver has insurance, just not enough to cover your injuries.

• Wisconsin's treatment of UIM has shifted over the years; it is at least offered, and at times has been required—so verify whether it is currently mandatory or optional.
• UIM pays the difference between the other driver's lower BI limit and your UIM limit.
• Stacking of UM/UIM across vehicles or policies is allowed only where law and the policy permit—verify Wisconsin's current rule.

The recurring theme: UM is mandatory, and UIM is at least offered—confirm the current rule before quoting a specific limit.

No PIP, plus the optional coverages

• Wisconsin does not require PIP / no-fault coverage. Medical Payments (Med Pay) is available as an optional first-party coverage that pays medical and funeral costs regardless of fault.
• Collision and Comprehensive (Other Than Collision) are optional, though a lender will usually require them on a financed vehicle. Remember that damage from hitting an animal—a deer collision, very common in Wisconsin—is Comprehensive, not Collision.

Cancellation and nonrenewal notice

Wisconsin limits how and when an insurer can end a personal auto policy, and requires advance written notice within statutory time frames. The timelines are commonly cited as follows:

• Cancellation for nonpayment of premium uses a shorter notice (often around 10 days)—verify.
• Other mid-term cancellations require a longer advance written notice, and after a policy has been in force a set time (often 60 days) the insurer may cancel only for limited reasons—chiefly nonpayment, driver's-license suspension/revocation, or fraud/material misrepresentation.
• Nonrenewal (declining to continue at the end of the term) likewise requires advance written notice so the insured can shop for replacement coverage.

Keep the short nonpayment window separate from the longer ordinary-cancellation / nonrenewal window.

Required vs. optional coverages in Wisconsin

Key Wisconsin numbers to memorize

Common exam traps

• Wisconsin is at-fault, not no-fault—there is no mandatory PIP here.
• 25/50/10—don't transpose the $10k property-damage figure into a bodily-injury slot, and note it differs from many states' figures.
• UM is mandatory in Wisconsin; it is not an optional add-on the customer must request.
• The 51% bar. A claimant more than 50% at fault recovers nothing; exactly 50% can still recover a reduced amount—verify.
• UIM fills the gap (your UIM limit minus the other driver's BI payment); it isn't a second full benefit on top.
• Hitting a deer is Comprehensive, not Collision.
• Liability defense costs are paid in addition to the limit (national rule that still applies in Wisconsin).

Quick recap

• The PAP keeps its national Parts A–F structure; Wisconsin changes the limits and legal context.
• Wisconsin is a tort/at-fault state using modified comparative negligence—the 51% bar means a claimant more than 50% at fault recovers nothing.
• Financial-responsibility minimums are commonly cited as 25/50/10 (verify).
• Uninsured Motorist BI is mandatory (at least 25/50), and Underinsured Motorist is at least offered.
• Wisconsin has no mandatory no-fault/PIP; Med Pay and physical damage are optional.
• Cancellation for nonpayment uses a short (~10-day) notice; ordinary cancellation/nonrenewal uses a longer notice—verify the exact days.
