The Safe Transit Act aims to reduce crime on public transportation systems by tying federal funding to crime-reduction performance and safety measures. Large transit agencies serving areas with more than 200,000 people must enforce fares, implement crime prevention programs including operator compartment barriers and surveillance cameras, and ensure that states criminalize fare evasion and restrict release-on-recognizance for transit crimes, or face losing up to 100% of their federal transit funds beginning in 2028. The bill requires a 3% set-aside of federal transit funds specifically for safety projects, mandates that new buses and rail vehicles be equipped with inward and outward-facing cameras within one year, and requires transit systems to display annual "Family Friendly Transit Scorecard" grades at stations and publish images of crime suspects online within a week of incidents. The Secretary of Transportation must establish performance targets for crime reduction within 90 days and can withhold funding from agencies whose crime rates exceed the national average by 10% or more.
