Federal trucking regulators let driverless trucks warn traffic with a cab beacon instead of triangles
The Federal Motor Carrier Safety Administration granted Aurora and other carriers running Level 4 automated trucks a limited five year exemption. It covers the rules on placing warning triangles and flares around a stopped truck. A carrier that notifies the agency first may instead use warning beacons mounted on the cab. The agency found the beacons likely as safe as the triangles a driver would set out. The exemption runs from October 7th, 2026 to October 7th, 2031. The Texas Trucking Association is listed among supporters, and the Owner-Operator Independent Drivers Association among opponents. It applies on every Texas road a driverless truck uses.
How to take part
The decision is final and carries no comment window. The docket, FMCSA-2026-0958, holds Aurora's application and the public comments, and questions go to the agency's Vehicle and Roadside Operations Division.
