Every entity registered with the US Federal Motor Carrier Safety Administration — one wide row per USDOT number, with carrier identity (legal and DBA name, physical location), operating authority and record status, fleet size (power units, trucks, drivers, CDL holders), hazmat indicator, and safety rating. Built from FMCSA's own Company Census File bulk export. Query by DOT number, company name, state, or safety rating to look up or screen carriers.
This is a constant-vintage monthly snapshot of the census: every row reflects the carrier's state as of the export vintage, refreshed on a monthly cadence. Licensing & Insurance authority/insurance event history is a separate forthcoming dataset and is not part of this snapshot.

Data quality — self-reported fleet size
power_units and total_drivers are self-reported FMCSA MCS-150 census figures, not audited counts. The default "biggest carriers" ranking (when neither min_power_units nor dot_number is given) filters out fleet-size self-reports that look implausible — data-entry sentinels (e.g. exactly 99,999 or 100,000), physically-impossible driver ratios, and suspiciously round high-end values — that would otherwise dominate the top of an unbounded sort. Real giants (FedEx 138,481 power units, UPS 112,321) are unaffected. Every response also carries a data_quality_note field restating this. Rows are never hidden from the dataset — pass an explicit min_power_units or dot_number to see unfiltered self-reports directly.
