Driving uninsured

Wis. Stat. 344.65, per Wisconsin Legislative Council issue brief, April 2024

Insureon reports that its Wisconsin customers pay an average of $178 a month, or $2,138 a year, for commercial auto, based on policies bought through it as of March 2026. Most of those customers have fewer than five employees, so the figure mostly reflects cars, pickups and vans used by small service businesses. A for-hire truck that needs a $750,000 WisDOT filing, a passenger carrier or a hazmat hauler should expect much more. Your own price depends on the vehicles, the limits your customers require, where vehicles are garaged and each driver’s record.

What moves your price

Vehicle type and weight: WisDOT filing minimums jump from $300,000 to $750,000 for for-hire trucks over 10,000 pounds
Whether you haul goods or people for pay, which brings state filings and higher limits
Garaging county and routes: Waukesha, Washington and Sheboygan counties led the state in deer crashes in 2025
Each driver’s record and experience with the vehicle class
The liability limits your customers or contracts require above the 25/50/10 floor
Optional coverage you add: underinsured motorist, medical payments, collision and comprehensive
Hazardous materials, which raise for-hire filing minimums to $1,000,000 or $5,000,000

Wisconsin

What’s different in Wisconsin

25/50/10 leaves $10,000 for property damage

Wisconsin’s floor is $25,000 per person and $50,000 per accident for injuries and $10,000 for property damage, per Wis. Stat. 344.33 and 632.32. A box truck that rear-ends a new pickup or damages a storefront can exceed $10,000 on its own, and anything above your limit falls on your business.

At 51% fault, you can owe the whole judgment

Under Wis. Stat. 895.045, an injured person can recover if their own fault is not greater than yours. A defendant found 51% or more at fault is jointly and severally liable for all the damages, not just its share. Commercial vehicles are often the deepest pocket in a multi-car crash.

Deer crashes peak in the fall

WisDOT counted 17,793 crashes involving deer in 2025, with 6 deaths and 720 injuries, and 42% happened from October through December. The OCI notes that most policies pay for hitting an animal under comprehensive, not collision, so a liability-only van is not covered for the damage.

An uninsured crash puts every registration at risk

After a crash with injury, death or property damage of $1,000 or more, Wisconsin’s Safety Responsibility Law lets DOT require an uninsured driver to deposit security. If the driver also owns the vehicle and does not pay, DOT suspends the license and all of the owner’s registrations, and it can order vehicles impounded.

Hauling for pay in-state needs a filing first

For-hire carriers of property or passengers must have their insurer file proof of insurance with WisDOT before operating. WisDOT will not issue registration, trip permits or intrastate authority without it, and the name on the policy must match the authority holder exactly.

Coverage

Coverage Wisconsin businesses need

Auto liability

Pays for injuries and property damage your vehicles cause to others. Wisconsin requires at least 25/50/10, and WisDOT for-hire filings are made against this coverage as a combined single limit.

How commercial auto works →

Uninsured motorist

Required on every Wisconsin policy at $25,000 per person and $50,000 per accident. It pays bodily injury to your driver and passengers caused by an uninsured or hit-and-run driver, but not damage to your vehicle.

How commercial auto works →

Underinsured motorist

Optional, but your insurer must tell you it is available. If you buy it, the limits must be at least $50,000 per person and $100,000 per accident, per the OCI.

How commercial auto works →

Medical payments

Insurers must offer it, with a minimum of $1,000 per person. It pays medical or funeral costs for people in your vehicle regardless of fault, usually for expenses within a year of the crash.

How commercial auto works →

Collision and comprehensive

Pays to repair your own vehicles. Comprehensive is the coverage that usually pays for a deer strike, and a lender will normally require both on a financed vehicle.

Hired and non-owned auto

Covers liability when employees drive their own or rented vehicles for your business, which a policy listing only company vehicles may not do.

Umbrella or excess

Adds limits above your auto liability when a contract asks for more than your primary limit or one serious crash could exceed it.

Rules

Wisconsin requirements

Every vehicle on a Wisconsin highway needs liability and uninsured motorist coverage. Carriers hauling goods or passengers for pay also need insurance on file before they operate, and customers often ask for more.

Requirement	Applies to	What it means
Minimum liability	Every motor vehicle operated on a Wisconsin highway	$25,000 per person, $50,000 per accident and $10,000 property damage (Wis. Stat. 344.62, 344.33 and 632.32). Going without is a forfeiture of up to $500 under 344.65; the 2024 amount with costs was $200.50.
Uninsured motorist	Every policy	At least $25,000 per person and $50,000 per accident, bodily injury only, under Wis. Stat. 632.32(4).
Underinsured motorist and medical payments	Every policy	Insurers must offer both. UIM, if bought, needs at least $50,000/$100,000; medical payments starts at $1,000 and can be rejected (Wis. Stat. 632.32(4) and (4m)).
For-hire property filing	Intrastate and interstate for-hire property carriers	$750,000 combined single limit for vehicles over 10,000 lb and $300,000 at 10,000 lb or less, filed by the insurer on Form E (Wis. Admin. Code Trans 176.06).
Hazardous materials filing	For-hire carriers of oil, hazardous waste or hazardous materials	$1,000,000, or $5,000,000 for bulk hazardous substances, certain explosives, poison gas and compressed gas, under Trans 176.06.
For-hire passenger filing	Passenger carriers operating only in Wisconsin	$300,000 at 10,000 lb or less; over 10,000 lb, $500,000 for up to 15 seats and $1,000,000 for 16 or more, including the driver, per WisDOT.
Cancellation notice	Insurers of filed motor carriers	A cancellation filed on Form K takes effect only 30 days after WisDOT receives it, unless a replacement filing is accepted (Trans 176.04).
Intrastate operating authority	For-hire property and passenger carriers operating only in Wisconsin	Apply to WisDOT on form MV2843 for an LC (property) or PC (passenger) number. Taxis, car and van pools of 7 or fewer and school buses are exempt from passenger authority.
USDOT number	Commercial vehicles of 10,001 lb or more, including intrastate	Trans 327.03(1) adopts 49 CFR 390.19. WisDOT will not process the vehicle’s registration without a valid USDOT number.

Pay less

How to lower the cost

If you hold federal authority, have your insurer file with FMCSA: WisDOT accepts that filing for intrastate operation, so you do not need a second one.
Make the named insured on your policy match your WisDOT customer record exactly, including middle name, so your Form E is not rejected and your registration is not held up.
Check motor vehicle records before hiring drivers and recheck them every year.
Train drivers to brake firmly and stay in their lane for deer, as WisDOT advises, rather than swerve into a more serious crash.
Raise collision and comprehensive deductibles on older vehicles you could afford to repair.
Shop when the renewal notice arrives; Florin is an independent broker that compares options from several insurers.

Common questions

Commercial auto insurance in Wisconsin: questions

Is underinsured motorist coverage required in Wisconsin?

No. Uninsured motorist coverage is mandatory, but underinsured motorist coverage is optional; your insurer must tell you it is available, and if you buy it the limits must be at least $50,000 per person and $100,000 per accident.

Does my FMCSA insurance filing cover intrastate trips in Wisconsin?

Yes. WisDOT says a filing with FMCSA for interstate operating authority meets the Wisconsin intrastate filing requirement, so for-hire carriers with federal authority do not file separately.

Does a contractor’s pickup need a WisDOT insurance filing?

Not if you carry only your own tools and materials. State filings apply to for-hire carriers, rental companies and certain passenger vehicles, but a truck or trailer combination rated at 10,001 pounds or more still needs a USDOT number.

Does commercial auto pay if my van hits a deer?

Usually only if you carry comprehensive. The OCI says most policies cover hitting an animal under comprehensive rather than collision, and liability coverage does not pay for your own vehicle.

How much notice must my insurer give before changing my commercial renewal?

For commercial policies, the OCI says an insurer cannot alter terms until 60 days after mailing notice, unless the only change is a rate increase under 25%. Nonrenewal also requires at least 60 days’ notice.

Can Wisconsin police stop me just to check for insurance?

No. Wis. Stat. 344.65(3) bars officers from stopping or inspecting a vehicle solely to check for coverage, but drivers must show printed or electronic proof when an officer asks.
