Fleet and driver counts are self-reported by each company on FMCSA Form MCS-150 and can be out of date. Values that look like typing errors (for example 99,999 trucks for a small company) are treated as not reported. Pages list companies registered as businesses; owner-operators registered as individuals are counted in totals but not named.

Frequently asked questions
- 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.
- What is a MC number?
- 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.
