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.

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

200 hours-of-service / ELD violations on record · most recent Jun 11, 2026. FMCSA does not publish the ELD device brand; these are the carrier's logging-compliance signals.

140ELD device issues

19False logs
18Drove over hours

Trending worse — 76% of ELD violations are in the last 24 months. Falsified-log violations are a serious integrity flag.
