Two US lawmakers, Democrat Raja Krishnamoorthi and Republican Michael Cloud, plan to introduce the No FLOCK Act, a bill that would cut federal highway funding to states that fail to restrict use of Flock and similar automatic licence-plate reader cameras. The move follows growing backlash over police misuse of the surveillance technology, including officers reportedly using footage to track former romantic partners, and comes as such devices become a prominent issue ahead of the US midterm elections.

The bill would require states to limit camera use to just five purposes, such as toll enforcement, locating stolen vehicles or missing persons, and investigating felonies, excluding uses like traffic studies, minor drug cases, and parking or speeding enforcement. States that do not comply would lose 10% of annual federal transportation funding from October 2028, potentially costing tens to hundreds of millions of dollars. The bill stops short of banning Flock cameras outright or restricting data-sharing with agencies such as immigration authorities, and its prospects remain uncertain given President Trump's public support for the technology and Flock's active lobbying efforts in Washington.
