Common questions
Is this really free?
Yes — every section, for any carrier, with no account. It is built on FMCSA public records, which anyone is entitled to read. We built it because we already pull this data for our customers, and a free lookup is how most people meet us.
Where does the data come from?
FMCSA's own published datasets: the Company Census file, the Motor Carrier Management Information System inspection and violation feeds, the SMS BASIC measures file, and the Licensing & Insurance tables. Nothing here is our opinion of a carrier — it is the federal record, laid out so you can read it.
Why is a percentile blank when the carrier clearly has violations?
FMCSA only ranks a carrier in a BASIC once it has enough relevant inspections to rank fairly — and it publishes the result as "Not Public" below that floor. We show a blank rather than inventing a number. A blank means too little data, never a clean record.
How current is it?
Inspections update daily at FMCSA, BASIC measures monthly, and violation detail lags its inspection by roughly six to eight weeks. Each report shows when we pulled it.
