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.

Few roadside inspections for a 389-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

15 hours-of-service / ELD violations on record · most recent Oct 17, 2025. FMCSA does not publish the ELD device brand; these are the carrier's logging-compliance signals.

9ELD device issues
3No log / no ELD
1False logs
1Drove over hours

Trending worse — 78% of ELD violations are in the last 24 months. Falsified-log violations are a serious integrity flag.
