Each date applies to its own record. A registration change does not mean every filing changed. An inspection or vehicle observation describes that date, not continuous operation today.

USDOT registration and operating authority are different records. A crash entry records involvement, not a finding of fault. Missing information is not a clean safety record.

More than 25 other USDOT registrations list the same officer, so they are not listed one by one.

Matched on FMCSA filings: company officer names, phone and physical address. Large fleets and shared office buildings can match by chance.

FMCSA filing records

Authority, insurance and notice records can include earlier filings. Read each recorded status and effective date; a filing alone does not confirm current authority or insurance coverage. Missing records do not establish unauthorized operation or missing insurance.

Amounts are shown exactly as filed, without scaling or currency conversion. Confirm coverage and amounts with the insurer.

A roadside out-of-service finding applies to the inspected driver or vehicle; it is different from a federal order against the carrier. Crash involvement does not determine fault or preventability. Counts cover the stated reporting period, not the carrier’s entire history.
