Authority & Insurance

Operating authority by docket

Loading this official source… values are not shown until it answers (not zero).

Authority status history

Loading this official source… values are not shown until it answers (not zero).

Status and reason text are shown exactly as FMCSA publishes them. The change date is FMCSA's status_change_date; “Dataset updated” is when FMCSA last published the file, and “Fetched” is when VAX read it. The two authority files are shown side by side and are not reconciled by VAX. Amounts: the dictionary says “thousands”, but published values look like dollars, so raw values are shown. Census status is not authority.

Insurance filings

Loading this official source… values are not shown until it answers (not zero).

Filings as recorded by FMCSA — not a certificate of insurance or proof of current coverage. Amounts are source values (dictionary: thousands).
