Percentile = standing among same-exposure peers (higher = worse). FMCSA publishes percentiles for only some carriers (shown official); elsewhere we show a Vektor peer-percentile estimate, or the absolute SMS measure when there are too few inspections to rank.

ELD & hours-of-service

No hours-of-service or ELD violations on record across 1 inspections — a clean logging history.
