What is a USDOT number?

The U.S. Department of Transportation number identifies a company that operates commercial vehicles hauling cargo or passengers in interstate commerce, and in many states for trips within the state too.

An MC (motor carrier) number is the operating authority FMCSA grants to for-hire carriers that move regulated goods or passengers across state lines. Private carriers hauling their own goods do not need one.

What do the safety ratings mean?

FMCSA rates a carrier Satisfactory, Conditional or Unsatisfactory after an on-site compliance review. Most carriers have never had a review and are unrated, which does not mean they are unsafe.
