Wisconsin Trucking Insurance Requirements

The Wisconsin Department of Transportation (WisDOT) regulates intrastate motor carriers. You need to register with WisDOT for intrastate authority. Wisconsin's intrastate requirements follow federal minimums.
Workers Compensation for Trucking in Wisconsin
Wisconsin requires workers' comp for employers with 3 or more employees (including part-time and family members). Employers with fewer than 3 can opt in voluntarily. Wisconsin uses its own independent rating bureau (WCRB — Wisconsin Compensation Rating Bureau), not NCCI. This means WI sets its own classification codes and rates.
WC premiums in Wisconsin are moderate — $4,000–$8,500 per driver annually.
Additional Coverage Requirements
Wisconsin doesn't mandate UM/UIM for commercial vehicles, though insurers must offer it. No PIP or no-fault requirements — Wisconsin is a tort state. You can reject UM/UIM in writing.
Wisconsin's severe winters — particularly in the northern half of the state — create seasonal risk factors. Lake-effect snow near Green Bay and the I-43 corridor can be especially challenging.
What Truck Insurance Costs in Wisconsin
Single-truck operations in Wisconsin pay $8,000–$14,000 annually. Milwaukee metro carriers pay more due to traffic density and proximity to Chicago freight patterns. Rural Wisconsin (northern and western regions) is more affordable. New authorities: $11,000–$18,000.
I-94 (Milwaukee to Madison to Minneapolis — a major freight corridor), I-90 (Madison to La Crosse), I-43 (Milwaukee to Green Bay), and I-39 (central Wisconsin) are the primary corridors.
