Wisconsin Commercial Auto Insurance Requirements

Wisconsin mandates commercial auto liability insurance at 25/50/10 split limits for most business vehicles, along with mandatory uninsured motorist coverage at 25/50 limits. Higher minimums apply based on your vehicle's gross weight rating, the number of passengers you transport for hire and whether your cargo includes federally regulated hazardous materials.

What Commercial Auto Insurance Is Required in Wisconsin?

Under Wisconsin Statute 344.62 and Chapter 632.32, every business operating a motor vehicle on state highways must carry commercial auto insurance requirements meeting at least these liability minimums:

$25,000 for bodily injury or death of one person per accident
$50,000 for bodily injury or death of two or more people per accident
$10,000 for property damage per accident

Wisconsin also requires uninsured motorist coverage at $25,000 per person and $50,000 per accident under Statute 632.32. These limits apply to standard commercial vehicles used for everyday business, not for-hire passenger operations, vehicles exceeding 10,001 pounds GVWR, or hazmat haulers, which all carry higher thresholds.

Wisconsin coverage minimums for commercial vehicles increase with gross vehicle weight, following federal FMCSA classifications for intrastate for-hire carriers hauling non-hazmat cargo. Operations that cross state lines, or handle any segment of an interstate shipment, fall under federal rules, regardless of vehicle weight. These tiers don't apply to vehicles used solely for personal errands or commuting, even if registered to a business.


0–10,000 lbs	25/50/10 state minimum	Light-duty commercial vehicles
10,001–20,000 lbs	$300,000 CSL	Medium-duty for-hire carriers
20,001–26,000 lbs	$300,000–$750,000 CSL	Larger delivery and service trucks
26,001+ lbs	$750,000 CSL	Heavy-duty freight, CDL required

Your vehicle's GVWR is the maximum allowable operating weight, including the vehicle, fuel, driver, passengers and cargo, not its weight at the time of inspection. A half-empty box truck with a GVWR of 14,000 pounds still falls in the 10,001- to 20,000-pound tier, even when empty. Find this rating in these locations, listed from most to least accessible:

On your vehicle: On the driver-side door jamb, door edge or pillar, and sometimes inside the engine bay. It may also be listed as GAWR (axle ratings).
Owner's manual: Check sections labeled specifications, vehicle identification, weight information, towing/trailering or technical data.
Manufacturer website: Search by your vehicle's model year and trim level for published specifications.

Wisconsin for-hire passenger carrier requirements are tied to the vehicle's rated seating capacity, not the number of passengers on board at the time of a stop or accident. The biggest jump hits at 16 passengers, where federal FMCSA minimums take over. These limits apply to intrastate for-hire operations only; carriers crossing state lines must meet separate federal requirements, and businesses transporting their own employees don't fall under for-hire passenger rules.


1–8 passengers	100/300/50 split limits	Taxis, local livery, small shuttles
9–15 passengers	$1,500,000 CSL	Airport shuttles, midsize charter
16+ passengers	$5,000,000 CSL	Charter buses, tour buses, transit

Wisconsin Statute 440.48, enacted through 2015 Wisconsin Act 16, requires TNC drivers and companies to carry primary auto insurance from the moment the driver's app is active, not only when a passenger is present. Traditional taxicabs, limousines and other for-hire vehicles regulated separately under Wisconsin law are not covered by these requirements.


App on, waiting for request	Driver or TNC (contingent)	50/100/25 liability
Ride accepted, en route to pickup	TNC provides	$1,000,000 CSL
Passenger in vehicle	TNC provides	$1,000,000 CSL

Wisconsin Statute 440.48(3)(a) expressly allows personal auto insurers to exclude all claims during TNC service, including Period 1 when no ride has been accepted. Drivers without a rideshare endorsement risk a total coverage gap for both liability and physical damage to their own vehicle.

Federal FMCSA hazmat rules govern all hazardous materials transport in Wisconsin, whether the route stays local or crosses state lines. Wisconsin doesn't separately regulate non-hazmat cargo by commodity type; those coverage minimums are set by the vehicle's weight classification.


General non-hazmat freight	$300,000–$750,000 CSL (by weight)	Standard goods, equipment, supplies
Household goods	$750,000 CSL	Moving company shipments
Standard hazmat	$1,000,000 CSL	DOT-regulated flammables, corrosives and other materials per 49 CFR Part 171
High-risk hazmat	$5,000,000 CSL	Tanks exceeding 3,500 gallons, Class A or B explosives, poison gas, radioactive materials

Wisconsin's $5 million high-risk hazmat requirement follows the cargo, not the truck. A vehicle under 10,001 pounds GVWR carrying Class A explosives, poison gas or radioactive materials must meet the same liability threshold as a full-size tanker. Carriers hauling non-hazmat freight use the vehicle weight table for their minimums.

WHEN DOES FEDERAL LAW APPLY OVER WISCONSIN LAW?

Federal commercial auto insurance requirements override Wisconsin state law when your operations involve transporting cargo or passengers across state lines, or when you handle any segment of an interstate shipment, even if your route stays within Wisconsin. The federal threshold applies to for-hire vehicles with a GVWR of 10,001 pounds or more. Check with the Wisconsin Department of Transportation Motor Carrier Services, review the federal insurance filing requirements through FMCSA and consult a licensed insurance professional to confirm which rules govern your operation.

Wisconsin Commercial Auto Insurance Requirement Exemptions

Wisconsin's exemption framework under Chapter 344 addresses how financial responsibility is proven, not who is exempt from the coverage mandate. The state accepts surety bonds, self-insurance certificates and cash deposits as alternatives to a standard commercial auto liability policy.


Self-insured fleet (26+ registered vehicles)	Self-insurance certificate under Statute 344.16
Surety bond filed with WisDOT	Bond under Statute 344.36
Cash or securities deposit of $60,000	Deposit under Statute 344.37, held in trust
Motor carrier with insurance filings under Chapter 194	Motor carrier insurance under Statutes 344.51/344.52
Vehicle used only for personal purposes	Personal auto insurance under Statute 344.62
Government vehicles (federal, state, county, municipal)	Government entity exemption under Statute 344.63(1)(f)

These exemptions apply statewide but aren't available to interstate motor carriers, who must file proof of insurance directly with FMCSA. Contact WisDOT Motor Carrier Services or the Office of the Commissioner of Insurance to confirm whether an exemption applies to your operation.

Wisconsin Commercial Auto Insurance Alternatives

Wisconsin recognizes three alternatives to a standard commercial auto liability policy under Chapter 344:

Surety bond: A surety bond of at least $60,000 filed with WisDOT under Statute 344.36 satisfies the financial responsibility requirement. The bond must stay active for the duration of vehicle operation, and WisDOT must be notified before cancellation.
Self-insurance: Fleet operators with more than 25 registered motor vehicles can apply for a self-insurance certificate from the secretary of transportation under Statute 344.16. Approval requires demonstrating sufficient financial capacity to cover claims without a traditional policy.
Cash deposit: Under Statute 344.37, a vehicle owner can deposit $60,000 in cash or qualifying securities with WisDOT instead of carrying a standard policy. The depositor must have no unsatisfied judgments in their county of residence; WisDOT holds the funds in an interest-bearing trust account.

Special Wisconsin Commercial Auto Insurance Coverage Circumstances

Some Wisconsin businesses have coverage gaps or additional requirements beyond a standard commercial auto policy.

Leased commercial vehicles

Wisconsin lessors generally add lessees to their policies or require the lessee to carry at least state minimums. Wisconsin's $10,000 property damage floor won't cover the remaining balance on a totaled leased vehicle, so gap insurance is worth considering to bridge the shortfall between actual cash value and the lease balance.

Seasonal and agricultural operations

Wisconsin farm vehicles that use public roads must carry the state's 25/50/10 minimum liability coverage under Statute 344.62. Vehicles operating exclusively on private farmland without touching public highways may fall outside the road-use mandate, but any use on a public road triggers full coverage requirements.

Great Lakes port and ferry operations

Wisconsin's Lake Michigan and Lake Superior shorelines include active ports in Green Bay, Milwaukee, Superior and Manitowoc. Standard commercial auto policies may exclude coverage during waterborne transport, ferry crossings or dock staging, so businesses moving vehicles through these ports should verify their policy addresses those scenarios.

Wisconsin Commercial Auto Insurance Enforcement and Penalties

Wisconsin verifies insurance compliance during traffic stops, accident investigations and other lawful police encounters, but Statute 344.65(3) prohibits officers from stopping a vehicle solely to check for insurance. Violations found during stops made for other reasons can still result in a citation.


Uninsured at-fault accident	Varies	License and registration suspended	SR-22 for 3 years or serve 1-year suspension
Covered but no proof on hand	$10	None	Show valid proof to dismiss
First offense, no coverage	Up to $500	Possible suspension	SR-22 filing + $60 fee
Repeat offense, no coverage	Up to $500	License and registration suspended	SR-22 for 3 years + fees
Fraudulent proof of insurance	Up to $5,000	Suspension	Full compliance required

Wisconsin requires an SR-22 certificate filed by your insurer with WisDOT for reinstatement after insurance-related suspensions, kept active continuously for three years, and any lapse resets the clock. Wisconsin's Safety Responsibility Law under Chapter 344 also imposes additional license and registration sanctions on uninsured drivers involved in accidents, and the state's comparative fault system means you remain financially responsible for damages proportional to your fault with no policy to absorb the cost.

How to Verify Your Business Meets Wisconsin Commercial Auto Insurance Requirements

Run through these steps for each vehicle in your Wisconsin fleet.

1
Classify each vehicle by its primary business use
Determine whether each vehicle hauls freight, transports passengers for hire, carries equipment or serves a general purpose. The use classification determines which Wisconsin insurance tier applies.
2
Look up every vehicle's GVWR
Check the driver-side door label for the Gross Vehicle Weight Rating. Vehicles at or above 10,001 pounds may fall under federal FMCSA oversight.
3
Sort out state versus federal jurisdiction
Wisconsin state minimums apply if your vehicles stay local and don't handle interstate shipments. Federal requirements apply the moment a vehicle crosses state lines with cargo or passengers.
4
Match liability limits to the correct tier
Confirm each vehicle's coverage meets the Wisconsin minimum for its weight class, passenger capacity or cargo type.
5
Audit policy classifications against actual use
Confirm your insurer has each vehicle classified correctly and all authorized drivers listed. A mismatch can result in a denied claim.
6
Check registration and filing obligations
Wisconsin interstate carriers need a USDOT number and federal insurance filings through WisDOT Motor Carrier Services under Chapter 194.
7
Close any remaining coverage gaps
Check whether your operation involves leased vehicles, seasonal farm equipment on highways or Great Lakes port operations that your base policy doesn't cover.

Wisconsin Commercial Auto Insurance Requirements: Bottom Line

Wisconsin commercial auto requirements come down to four variables: vehicle use, weight class, cargo type and whether operations cross state lines. Before renewing or buying coverage, confirm your policy limits and vehicle classifications match the correct tier for each vehicle in your fleet.

Wisconsin Commercial Auto Insurance Requirements: Next Steps

Wisconsin's legal minimums are the floor, not the finish line. Most businesses that depend on their commercial vehicles for revenue need limits well above the state-mandated thresholds.
