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 5-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.
