A vehicle from self-driving truck maker Otto will travel a 35-mile stretch of U.S. Route 33 on Monday in central Ohio between Dublin and East Liberty, home to the Transportation Research Center, an independent testing facility. It will travel in regular traffic, and a driver in the truck will be positioned to intervene should anything go awry, Department of Transportation spokesman Matt Bruning said, adding that “safety is obviously No. 1.” “Certainly we think it’s going to be one of the foremost automotive research corridors in the world,” Bruning said.
