Fleet vs Reality
last 12 months · power-unit VINs from roadside inspections
Weighted heuristic: crashes are decayed by recency and normalized per 100 power units, out-of-service and violation rates use a rolling 24-month window, plus FMCSA BASIC alerts and the CarrierIntel Safety Score (which also decays when compliance has not been verified by a recent inspection). Not the official FMCSA SMS score.
