49 CFR 12.2

Not found in the current CFR. No part 12 exists under title 49 in the eCFR as of 2026-08-23. That means either the part was removed or renumbered, or the citation in the publication is wrong. Either way, verify before relying on it — this is exactly the kind of stale reference worth catching.

Citation counts come from the publication text, not from a summary. A high count is frequency, not legal weight — open the pub and read the citation in context.
