What Commercial Auto Insurance Requirements Apply in Wisconsin?

Wisconsin intrastate for-hire motor carriers must file liability insurance with WisDOT before operating: the property-carrier floor is $300,000 at 10,000 pounds gross weight or less and $750,000 above 10,000 pounds. The registered-owner name and insurance name must match exactly on an intrastate authority record, so confirm the legal entity and filing before applying for authority or vehicle registration.

What Is Commercial Auto Insurance?

Commercial auto suits businesses that use vehicles for work and need liability protection; damage to your own vehicles is a separate coverage choice. If employees drive personal or rented cars, check how those trips are handled. Read the national Commercial auto guide.

What Should You Watch for With Commercial Auto Insurance in Wisconsin?

Make The Policy Name Match The Authority Holder
WisDOT says the registered owner’s name and insurance name must match exactly on an intrastate operating-authority number; for an individual, the middle name must match too. Reconcile the entity name across registration, authority application, and insurer filing before dispatch, because proof on file is a prerequisite to authority and registration. ¹
Check The 10,000-Pound Property-Filing Boundary
Wisconsin sets $300,000 for property for-hire vehicles at 10,000 pounds gross weight or less and $750,000 above that weight. Use the weight figure WisDOT applies to the vehicle and confirm any hazardous-material exception before the insurer files the certificate. ^1,²
Check Whether Hazardous Material Moves The Filing To FMCSA
WisDOT says intrastate as well as interstate carriers transporting listed hazardous materials in a vehicle with GVWR of 10,000 pounds or more must file proof with FMCSA at the federal amount. Identify the material under 49 C.F.R. 172.101 and ask which federal filing applies before relying on the state property-carrier amount. ¹
Keep Coverage In Force During An Oversize Move
WisDOT says a carrier using an oversize/overweight permit must keep the required insurance in force while the vehicle and permitted load operate on a public highway. Confirm the policy remains active for the entire permitted trip, including a scheduled move that takes place after a renewal or vehicle change. ³

Which Commercial Auto Providers Have Wisconsin License Records?

These providers publish a national listing for Commercial auto; the license records below name the licensed entities and roles. Some records rely on company-reported information rather than independent regulator verification. A national listing does not confirm the product is available in Wisconsin. Check the regulator’s license lookup and confirm state availability for your business when requesting a quote.

Corgi’s company producer-license table lists 50 jurisdictions: 49 states and the District of Columbia, including DC license 3003091619. New Mexico does not appear in the table and is not included here; the omission does not establish that Corgi is unlicensed there.

Specialty Program Group LLC
TechInsurance’s current licensing page names Specialty Program Group LLC / SPG Insurance Solutions and lists state license numbers, but labels Rhode Island “Individual licenses” rather than identifying a license for the named agency. RI is omitted because this disclosure does not establish agency authority there; this is a search limitation, not an assertion that the company is unlicensed. The remaining state entries are company-reported and are not an insurance product availability map. ¹⁴
TechInsurance arranges commercial auto insurance for small businesses.

Surplus-Lines Tax and Stamping Office in Wisconsin

Reported tax rate. 3% of premium ^7,⁸

The NAIC's state chart lists a 3% of premium charge for surplus-lines coverage for Wisconsin (the chart's state entries were reviewed in October 2025). Your broker may collect the applicable amount with the premium. Surplus-lines insurers are not licensed in the state and generally are outside state guaranty-association protection; ask your broker to explain the insurer's financial protections and any diligent-search requirement that applies to your placement.
