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.

Not on file for USDOT 174639: connected companies, roadside inspections or crashes (24 months).

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.
