Improve the safety and efficiency of automated vehicle technology on public roads.
One policy goal, tracked across every bill that has carried it.
What’s happening with ACES Act of 2025?
The ACES Act became law on August 13, 2025, as Public Law 119-32. Federal agencies must now handle the rulemaking and funding steps to put these safety rules into practice. This effort is no longer in the hands of Congress, so the pace of change depends on agency capacity and court reviews.
