Part 390 — Federal Motor Carrier Safety Regulations; General
Between Sept. 30, 2009 and today (current through Oct. 22, 2026): 11 amended, 40 added, 0 removed, 10 unchanged.
Sept. 30, 2009 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.
