Fleet and driver counts are self-reported by each company on FMCSA Form MCS-150 and can be out of date.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. Check the carrier's current status, insurance and inspection history on FMCSA SAFER.
