Wisconsin has 65,728 active motor carriers registered with FMCSA, the 9th most in the country. The largest share is based in Milwaukee. About 54% are single-truck operations (close to the national average), and 9% hold active for-hire authority (below the national 15%).
New carriers in Wisconsin
663 new USDOT numbers in Wisconsin were registered in the last 90 days, 1.0% of the state's active carriers (a lower rate than the national 1.8%). New authorities aren't a problem in themselves, since every carrier starts somewhere, but many freight-fraud schemes use authorities only weeks old, so brokers often apply extra checks to them.
