Authority & Insurance

Operating authority by docket

No row matched this USDOT (bare or zero-padded) or its MC numbers. That alone does not prove the company has no authority — check FMCSA.

Authority status history

No authority status-change row matched. That does not prove there were no changes.

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

No row matched this USDOT (bare or zero-padded) or its MC numbers. That does not prove the company has no insurance — check FMCSA L&I.

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

Bars run only between published effective and cancellation dates. Current filings show their effective date only — no end is assumed and no continuous coverage is inferred. Current history: 3uet-3z4i; legacy rows from 6sqe-dvqs (frozen 2026-05-14) are kept only when not already in the current file.
