This revision responds to a petition for rulemaking from the Truck Trailer Manufacturers Association (TTMA). The revision provides relief from a regulatory requirement without impacting safety.Effective March 23, 2026. Petitions for reconsideration of this final rule must be submitted to the FMCSA Administrator no later than March 23, 2026.
