Arizona has 32,038 active motor carriers registered with FMCSA, the 21st most in the country. The largest share is based in Phoenix. About 52% are single-truck operations (close to the national average), and 17% hold active for-hire authority (above the national 15%).
New carriers in Arizona
680 new USDOT numbers in Arizona were registered in the last 90 days, 2.1% 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.
