Everything on the Proof Room page derives from a published, fingerprinted weekly test bundle. This page tells you how to check it yourself.
The exam is FMCSA's own ELD Test Plan & Procedures v2.1 (2017-07-18), a public federal document. The copy this ELD is graded against is pinned by SHA-256: 483149d66b50f575dc2df148c6328c3d5214127eadfba7dadef7254237b4ab47. Every one of the 314 cases carries its own named test.
Every weekly run is fingerprinted by the exact code commit that produced it. The short form renders beside the score; the run's own bundle carries the same commit inside it, so a bundle and the page that cites it can be matched byte-for-byte.
The raw evidence lives in a public bucket, one folder per weekly run: the machine-readable board (board.json), the rendered board (cert_board.html), and a manifest (meta.json) carrying a SHA-256 for every artifact. The index at index.json lists every run, newest first, red weeks included.
You don't have to take our word for the score. The test is FMCSA's own public document, each run is stamped to the exact code behind it, and every file is downloadable from a public folder, so anyone can re-check the results themselves.
a clean run—every test that ran, passed.
