Inspection coverage· expected vs observed · the fraud signal

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.

Roadside-inspection volume is about what you'd expect for a 344-unit fleet — enough signal to read the safety record, though not a heavy sample.

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.
