Part 392 — Driving of Commercial Motor Vehicles
Between Oct. 1, 2016 and today (current through Oct. 22, 2026): 7 amended, 0 added, 0 removed, 34 unchanged.
Oct. 1, 2016 falls before day-level history begins (Jan. 1, 2017). It is read from the annual CFR edition in force that day (revised as of October 1), so an amendment that took effect earlier in that edition year is counted as already in place. Federal Register citations on each section give exact effective dates.
