Driverless Trucks Are Coming: Expect More on Roads by 2027
The Federal Motor Carrier Safety Administration has granted a five-year exemption affecting Level 4 autonomous trucking operations, clearing the way for companies to expand driverless freight services on U.S. highways. The exemption addresses how autonomous trucks warn other motorists when they are stopped because of a mechanical problem.
Exemption Changes Roadside Warning Requirements
Under existing requirements for conventional commercial vehicles, a truck driver must activate the vehicle’s hazard lights and place roadside warning devices within 10 minutes after a breakdown or other emergency stop.
Autonomous trucking companies have argued that those rules were written for vehicles with human drivers. A driverless truck cannot leave the cab to deploy warning devices.
The exemption allows qualifying autonomous trucking companies to use cab-mounted warning beacons as an alternative. The exemption is available to Level 4 autonomous vehicle operators that provide prior notice to the agency.
Aurora Plans Continued Fleet Expansion
Aurora has been among the companies developing commercial driverless trucking operations. The company said its autonomous trucks had traveled more than 500,000 miles on the Dallas-Houston corridor by September 2026, following its commercial launch in April 2025.
Aurora was targeting approximately 200 driverless trucks in operation by the end of 2026. The company also has a manufacturing partnership with Volvo aimed at producing up to 1,000 autonomous tractors annually beginning in 2027.
Volvo Autonomous Solutions President Martin Lundstedt said the company expected to operate trucks without safety drivers on Texas roads during the first quarter of 2027.
Industry Impact
The exemption could make it easier for autonomous trucking companies to scale operations beyond limited pilot programs. Aurora has indicated that it intends to expand its driverless fleet substantially over the next several years.
The developments are focused on predefined freight corridors, including the Dallas-Houston route, where autonomous trucks can operate within mapped and monitored areas. Companies will still be subject to applicable federal and state requirements governing commercial vehicle operations and autonomous systems.
