South Carolina has 25,131 active motor carriers registered with FMCSA, the 29th most in the country. The largest share is based in Columbia. About 54% are single-truck operations (close to the national average), and 20% hold active for-hire authority (above the national 15%).
New carriers in South Carolina
558 new USDOT numbers in South Carolina were registered in the last 90 days, 2.2% of the state's active carriers (a higher 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.
