FMCSA denies the Aurora/Waymo warning-device exemption for driverless trucks; Aurora sues USDOT

On Dec 26 2024 FMCSA denied the joint Aurora/Waymo request to use cab-mounted warning beacons in place of human-placed warning triangles for disabled driverless trucks, calling it too broad and lacking monitoring controls; Aurora petitioned the D.C. Circuit / sued USDOT on Jan 10 2025 (a waiver was later granted Oct 2025).
