What the agency says

This final rule responds to petitions for reconsideration of the June 2022 final rule establishing Federal Motor Vehicle Safety Standard (FMVSS) No. 213a and the December 2023 final rule establishing FMVSS No. 213b. This final rule grants petitions to incorporate a dummy positioning procedure for shield-type child restraint systems (CRSs), clarify test procedure for CRSs with certain types of side impact technologies, remove testing CRSs installed with lap belt only in frontal sled tests, and correct inconsistencies in the regulatory text and figures in FMVSS Nos. 213a and 213b. This final rule also partially grants the petition to align compliance dates between the standards. All other requests are denied.
