Idaho has 13,917 active motor carriers registered with FMCSA, the 34th most in the country. The largest share is based in Boise. About 48% are single-truck operations (close to the national average), and 19% hold active for-hire authority (above the national 15%).
New carriers in Idaho
208 new USDOT numbers in Idaho were registered in the last 90 days, 1.5% 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.
