Wisconsin Tow Truck License Requirements (2026)
The Short Answer
In Wisconsin, towing is regulated by the Wisconsin DOT. Intrastate carrier registration. A CDL is only required when the truck plus towed vehicle exceeds 26,001 lbs GVWR.
Wisconsin operators lose weeks to the wrong paperwork order. This is the full WI license checklist, from federal registration down to city permits.
Required in Wisconsin
- Wisconsin LLC or corporation registration
- Federal EIN
- USDOT number (10,001+ lbs GVWR commercial operation)
- Wisconsin DOT: Intrastate carrier registration
- Proof of insurance filed with the state where required
- City or county tow permits in Milwaukee, Madison, Green Bay
CDL Thresholds
| Combined GVWR | License needed |
|---|---|
| Under 26,001 lbs | Standard WI driver's license |
| 26,001+ lbs, single unit | Class B CDL |
| 26,001+ lbs with 10,000+ lb towed unit | Class A CDL |
The Combination Trap
An F-550 flatbed at 19,500 GVWR carrying an 8,000 lb SUV is fine. Add a dolly-towed second vehicle and you can cross 26,001 lbs — CDL territory, even though the truck alone is not.
Driver-Level Requirements in Wisconsin
- DOT medical card for every commercial driver
- Clean MVR — insurers in WI decline drivers with recent major violations
- Drug and alcohol testing enrollment if CDL drivers are on payroll
- Background check where Wisconsin or the local police rotation requires it
Renewals and Deadlines
- USDOT biennial update — free, but the number is deactivated if missed
- UCR fee annually in most states
- Wisconsin tow authority renewal, typically annual
- Local permits renew on the city's fiscal calendar, not yours
