Anti-ejection glazing for bus portals
Latest notice (G/TBT/N/USA/1123/Add.2, 16 January 2026)
The latest notice says the measure was adopted or published.
Federal Motor Vehicle Safety Standards: Anti-Ejection Glazing for Bus Portals; Mandatory Applicability Beginning 30 October 2027
This document partially grants a petition for reconsideration of the 30 October 2024 final rule (notified as G/TBT/N/USA/1123/Add.1) that established Federal Motor Vehicle Safety Standard (FMVSS) No. 217a, ''Anti-ejection glazing for bus portals; Mandatory applicability beginning 30 October 2027.'' The standard intends to drive installation of advanced glazing in over-the- road buses (motorcoaches) and other large buses to reduce occupant ejections. This final rule revises the minimum size requirement for applicable portals, adds a figure to illustrate a daylight opening periphery, and clarifies the target location for edge impact tests. This document denies all other portions of the petition for reconsideration, including revising the definition of ''daylight opening.'' Effective Date: This final rule is effective 15 January 2026. Compliance Date: The compliance date of this final rule is 30 October 2027. Optional early compliance is permitted. Petitions for Reconsideration: If you wish to petition for reconsideration of this rule, your petition must be received by 2 March 2026. 91 Federal Register (FR) 1709, 15 January 2026; Title 49 Code of Federal Regulations (CFR) Part 571: This final rule; partial grant of a petition for reconsideration is identified by Docket Number NHTSA-2026-0001.

This NPRM proposes a new Federal Motor Vehicle Safety Standard (FMVSS) No. 217a, 'Anti-ejection glazing for bus portals,' to drive the installation of advanced glazing in high-occupancy buses (generally, over-the-road buses (of any weight) and non-over-the-road buses with a gross vehicle weight rating greater than 11,793 kilograms (26,000 pounds). The new standard would specify impactor testing of glazing material. In the tests, a 26 kilogram (57 pound) impactor would be propelled from inside a test vehicle toward the window glazing at 21.6 kilometers/hour (13.4 miles per hour). The impactor and impact speed would simulate the loading from an average size unrestrained adult male impacting a window on the opposite side of a large bus in a rollover. Performance requirements would apply to side and rear windows, and to glass panels and windows on the roof to mitigate partial and complete ejection of passengers from these windows and to ensure that emergency exits remain operable after a rollover crash. NHTSA also proposes to limit the protrusions of emergency exit latches into emergency exit openings of windows to ensure they do not unduly hinder emergency egress. This NPRM is among the rulemakings issued pursuant to NHTSA's 2007 Approach to Motorcoach Safety and DOT's Departmental Motorcoach Safety Action Plan. In addition, to the extent warranted under the National Traffic and Motor Vehicle Safety Act, establishing advanced glazing standards for the side and rear portals of…

This final rule establishes Federal Motor Vehicle Safety Standard (FMVSS) No. 217a, 'Anti-ejection glazing for bus portals; Mandatory applicability beginning 30 October 2027,' to drive the installation of advanced glazing in over-the-road buses (motorcoaches) and other large buses to reduce passenger and driver ejections. This final rule, issued pursuant to the Moving Ahead for Progress in the 21st Century Act (MAP-21), specifies impactor tests of the glazing material of side and roof windows. The impactor and impact speed simulate the loading from an average size unrestrained adult male impacting a window on the opposite side of a large bus in a rollover. Effective date: 30 December 2024. Compliance date: The compliance date for FMVSS No. 217a and the amendments to FMVSS No. 217 is 30 October 2027. Optional early compliance with the standards is permitted.
