U.S. Department of Transportation Secretary Elaine Chao on Tuesday rolled out revamped federal guidance for autonomous vehicle manufacturers, putting the Trump administration’s deregulatory stamp on the fast-developing industry.

The recommendations, dubbed “A Vision for Safety 2.0,” largely builds on the voluntary blueprint laid out for driverless car designers and developers in September 2016 by the Obama administration. But it also makes a number of industry-sought changes and clearly sets the National Highway Traffic Safety Administration’s role as one of championing—and not intensely regulating—the technology.
