Not enough inspection history to rate4 federal roadside inspections in the last 24 months. FMCSA itself will not score a carrier's vehicle or driver record on fewer than 5, and neither will we — verify authority, insurance and references directly before tendering.

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 7-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.
