What the agency says
This final rule amends NHTSA's regulation governing Event Data Recorders (EDR or EDRs) to delay the implementation schedule for expanded pre-crash data capture requirements. In response to petitions for reconsideration of a final rule published on December 18, 2024, the agency is adopting a four-year phase-in compliance schedule that begins September 1, 2028. This action ensures the increased pre-crash data capture requirements are integrated into the vehicle fleet in a manner that aligns with manufacturer production cycles and technical feasibility.
