Share of vehicle-level roadside inspections in each trailing six-month window that resulted in a vehicle out-of-service order. More resolved windows are needed to establish a trend. The national vehicle benchmark uses the same metric and is shown on the chart.

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.
