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.

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