State Safety Oversight (SSO) Program

Safety officers attend demonstration at Maryland Transit Administration in Baltimore

The purpose of the State Safety Oversight program is to oversee safety at rail transit systems. The SSO program is administered by eligible states with rail transit systems in their jurisdiction. FTA provides federal funds through the SSO Formula Grant Program for eligible states to develop or carry out their SSO programs. Under 49 U.S.C. Section 5329(e), as amended by the Moving Ahead for Progress in the 21st Century Act (MAP-21), FTA is required to certify each state’s program to ensure compliance with MAP-21. Review the list of SSO agencies.

What's New

State Safety Oversight Notice of Proposed Rulemaking

On November 15, 2023, FTA published a Notice of Proposed Rulemaking (NPRM) in the Federal Register proposing updated requirements for the State Safety Oversight regulation. The public comment period is open until January 16, 2024.

Risk-Based Inspection Programs

On October 21, 2022, FTA issued special directives to all State Safety Oversight Agencies (SSOA), the agencies that oversee safety at rail transit systems, to develop and implement a risk-based inspection program in accordance with changes to FTA’s Public Transportation Safety Program as required by the Bipartisan Infrastructure Law. A risk-based inspection program uses qualitative and quantitative data analysis to inform inspection activities and is designed to prioritize safety concerns and hazards associated with the highest levels of risk.
