FMCSA — Federal Motor Carrier Safety Administration carrier safety, crash, and inspection records. Vet third-party haulers (frac sand, produced water, crude, rig moves). No auth. CARRIER: getCarrierByDOT, searchCarriersByName, getCarrierByDocket. SAFETY: getCarrierBasics (BASIC scores), getCarrierAuthority (authority + insurance), getCarrierOOS. HISTORY: getCrashes (all-time), getInspections (rolling ~3yr). RULES: 1. DOT number is the primary ID — use searchCarriersByName to resolve it from a carrier name. 2. Subsidiaries file under different DOT numbers; name search returns up to 20 matches. 3. getCrashes is all-time; getInspections is a rolling ~3yr window — zero rows is not an error. 4. BASIC scores can be stale (runDate surfaced) — don't read percentiles as current.
