US motor carriers, in numbers

Everything below is computed from the carriers currently loaded, not from the full federal register — and that corpus is deliberately mixed: currently active carriers plus ones deactivated within the past year, which are over-represented on purpose so the deactivated case is visible at all. Treat the shares as describing this dataset, never as the share of US carriers. It moves when the corpus does.

Which states' carriers fail the most roadside inspections

The share of roadside inspections that ended in an out-of-service order, by the state the carrier is based in. A rate rather than a count, because this is a sample of the register — see the note below. States with fewer than 500 inspections on file are not rated.

How to read these

Every figure is computed from the carriers currently loaded and is recalculated periodically — it is a description of this dataset, not of the federal register as a whole. Counts come straight from what carriers filed on their own MCS-150; we do not correct them.
