Part 389 — Rulemaking Procedures—Federal Motor Carrier Safety Regulations
Between Sept. 30, 2012 and today (current through Oct. 22, 2026): 11 amended, 3 added, 0 removed, 8 unchanged.
Sept. 30, 2012 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.
