JOHN C DIEHL

The Verdica score is a composite trust score from 300 to 850, computed from safety inspection records and BASIC scores maintained by the FMCSA. A score of 673 places JOHN C DIEHL in PA in the acceptable (670–739) band. The score reflects publicly available regulator data — it is not a rating from Verdica itself and does not incorporate paid reviews or advertising.

Verdica combines three weighted sub-scores drawn from the FMCSA. Each sub-score reflects a different dimension of trucking compliance — operating authority, crash indicator, driver fitness, and vehicle maintenance — and is normalized against industry peers before being aggregated to the 300–850 scale.

Verdica pulls public records from the FMCSA: safety inspection records and BASIC scores. Data is refreshed on rolling cycles, typically weekly to monthly depending on the source agency's own update schedule. See the "source data current" indicator on the entity page for the last successful refresh.

Common negative signals include out-of-service orders, unsatisfactory safety ratings, or BASIC alerts. Any of these appear in the underlying regulator records and pull the sub-score down; the composite reflects the weighted impact.
