Event Data Recorders
Key claim: NHTSA is delaying the expanded pre-crash data capture requirements for Event Data Recorders by adopting a four-year phase-in compliance schedule beginning September 1, 2028, in response to manufacturer petitions for reconsideration.
Abstract
(Rule · Transportation Department, National Highway Traffic Safety Administration) 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.
Why this matters
EDR pre-crash data capture is central to crash reconstruction, defect investigations, and ADAS/autonomous vehicle performance evaluation. Delaying expanded requirements by several years pushes back when investigators and researchers can rely on standardized, richer pre-crash datasets across the light-vehicle fleet.
