Share of vehicle-level roadside inspections in each trailing six-month window that resulted in a vehicle out-of-service order. One window of data — no trend yet. The national vehicle benchmark uses the same metric and is shown on the chart.

Inspection coverage

How heavily FMCSA inspects this fleet for its size — it tells you how much to trust the safety signals above. Thin coverage on a young authority is a fraud signal nobody else surfaces.

Few roadside inspections for a 100-unit fleet — the out-of-service and violation signals above rest on a small sample, so weight them cautiously. Thin coverage on a young authority is itself a flag.

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 3 inspections — a clean logging history.
