Autonomous Truck Beacon Waiver Nears October 9 Renewal Test

A Federal Motor Carrier Safety Administration waiver allowing certain Level 4 autonomous trucks to use cab-mounted warning beacons instead of roadside triangles or fusees is scheduled to expire at 11:59 p.m. October 9. FreightWaves reported October 2 that the waiver is expected to be reissued unless a carrier violates its conditions, reports a safety problem or FMCSA identifies a deficiency.

The current waiver covers Aurora and other Level 4 automated-truck carriers that notify FMCSA and certify compliance. FreightWaves identified Kodiak Robotics, Waabi Logistics and Stack AV as participants. The arrangement is being challenged in the Seventh Circuit by Illinois cargo-van operator Kostas Giannoulias, who argues that repeated short waivers avoid the public process used for exemptions or pilot programs. The court had not ruled on his request for a stay as of October 2.

FMCSA's April Federal Register notice independently confirms the underlying safety issue. Existing rules generally require a stopped commercial vehicle to place warning devices within 10 minutes, while Aurora seeks to use high-mounted flashing amber beacons so a person does not have to enter the shoulder or traffic lane. Aurora's separate request for a five-year exemption remains pending after the comment period closed May 15.

Motor carriers should not read the waiver as a general change for conventional trucks. It applies only to eligible Level 4 operations that complete the agency's notification and certification steps and follow reporting conditions. Fleets testing automated equipment should track the October 9 status, document beacon performance and retain crash and activation records. Drivers of conventional vehicles must continue carrying and placing required warning devices unless a specific federal exemption or waiver applies to their operation.
