What this URL pins

This URL resolves a cited methodology version to the published text of that version. Every carrier page stamps the version it was rendered under in its footer, so a figure quoted from a carrier page can be traced to the formulas that produced it.

How to verify a figure

Recompute it. Every published figure is a deterministic function of public FMCSA records, and the derivation for each is written out at /methodology; what changed between versions is at /cite/integrity. Applying the same procedure to the same federal inputs reproduces the same number — that is the verification claim this site makes, and the only one it makes.

Canonical artifact

The canonical artifact for this version is the published methodology page itself. No PDF is distributed.
