About the data

Powers the search and summary cards. The full registration census for every USDOT number: legal/DBA name, physical & mailing address, phone, active/inactive status, MC docket number, power units, drivers, fleet size, operation classification, cargo types, safety rating, company officers, and MCS-150 filing date/mileage. No API key required; a free Socrata app token raises rate limits.

Powers the “USDOT registration”, “Operation & cargo”, and “Inspections & crashes” sections of the detail view. SAFER has no API — this site fetches the snapshot page and parses the HTML. It adds data the census lacks: USDOT status incl. out-of-service date, operating authority status, entity type, 24-month US inspection counts with out-of-service percentages and national averages, 24-month crash counts (fatal / injury / tow), and federal safety rating with review dates.

Powers the “Licensing & Insurance” section. The L&I website (li-public.fmcsa.dot.gov) sits behind a CAPTCHA, but FMCSA publishes the same records as open datasets: operating authority status (common / contract / broker) with pending applications and revocations, required vs. on-file BIPD insurance amounts, active insurance filings (form code, insurer, policy number, coverage, effective/cancellation dates), and the full authority grant/revocation history. Datasets used: 6eyk-hxee (carrier authority), qh9u-swkp (active/pending insurance), 9mw4-x3tu (authority history).

The official carrier API — the same backend behind FMCSA's QCMobile app. When a webKey is configured, search results use it (richer and fresher than the census); otherwise the site falls back to the census automatically. Registration is free but the host is intermittently unavailable.
