Old Roof-Crush Rule Removed
On July 6, 2026, NHTSA removes FMVSS No. 216 (the older roof crush resistance standard) and amends FMVSS No. 216a to clarify its applicability. FMVSS No. 216a already had a multi-year phase-in and required full compliance by Model Year 2016.
No Significant Small-Entity Impact
NHTSA certified under the Regulatory Flexibility Act that this final rule will not have a significant economic impact on a substantial number of small entities, so a regulatory flexibility analysis was not required. This certification accompanies the final rule effective July 6, 2026.
