The Safe Transit Accountability Act amends title 49, United States Code, to establish a definitive process for resolving disputes within public transportation safety committees. It designates an "accountable executive" for each transit agency, who will serve as the ultimate decision-maker regarding safety recommendations and as the sole tiebreaker for any committee disagreements. This executive is defined as the single individual with ultimate responsibility for the agency's Public Transportation Agency Safety Plan and Transit Asset Management Plan , possessing control over the necessary human and capital resources. The amendment aims to clarify authority, streamline the implementation of risk-based mitigation strategies, and enhance accountability in transit safety oversight and asset management.
