USA - Federal Motor Vehicle Safety Standards: Anti-Ejection Glazing for Bus Portals; Mandatory Applicability Beginning October 30, 2027

The document partially grants a petition for reconsideration of the October 30, 2024 final rule (FMVSS No. 217a) on anti-ejection glazing for bus portals, which mandates advanced glazing in large buses to reduce occupant ejections starting October 30, 2027.

The final rule revises the minimum size for applicable portals, adds a figure for daylight opening periphery, and clarifies edge impact test targets, while denying other requested changes, such as revising the definition of "daylight opening." 

The rule becomes effective on January 15, 2026, with optional early compliance allowed, and petitions for reconsideration must be submitted by March 2, 2026.
