Self-driving trucks are being tested on public roads in Virginia

Daimler Trucks and technology firm Torc Robotics have started to test autonomous trucks on public roads in the U.S. The routes are located on highways in southwest Virginia where Torc -- which is part of Daimler Trucks following a majority stake acquisition -- is based. In an announcement Monday, Daimler Trucks said that all of the "automated runs" would need an engineer to oversee the system as well as a safety driver. It added that all safety drivers held a commercial driver's license and had special training in vehicle dynamics and automated systems. The firm said that "months of extensive testing and safety validation" had already been conducted on a closed loop track. "Bringing Level 4 trucks to the public roads is a major step toward our goal to deliver reliable and safe trucks for the benefits of our customers, our economies and society," Martin Daum, a member of the board of management at Daimler with responsibility for trucks and buses, said in a statement.
