Rate = OOS inspections ÷ inspections, from the SMS summary; N/A when there are 0 inspections. The SMS summary has no monthly series; the monthly chart below is built from record-level inspections. Roadside inspections are a sample, not the whole fleet.

Computed from record-level inspections in fx4q-ay7w (window 2024-10-10 → 2026-10-10, fetched 2026-10-10 09:18 UTC). OOS rate = inspections with driver/vehicle OOS > 0 ÷ inspections at a driver/vehicle-examining level — not violation counts. Months with no eligible inspection leave a gap (not 0%). The SMS summary is not used to build history.

Driver-level = Levels I, II, III, VI; vehicle-level = Levels I, II, V, VI (FMCSA North American Standard levels). Level IV special studies are in neither. These record-level counts can differ from the SMS summary above, which uses its own snapshot and is left unchanged.

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.

Source: Motus AuthHist – All With History (yu5v-wbh6) · raw queryDataset updated 2026-10-09 14:33 UTCFetched 2026-10-10 09:18 UTC

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).

No ended-policy rows matched in the current (3uet-3z4i) or legacy (6sqe-dvqs) insurance history. That does not prove there were no prior policies.
