ANN ARBOR, Mich. — At a time of growing concern about the safety of self-driving vehicles, a leading expert is calling on the federal government to develop a national driver's test that such vehicles would have to pass before they could travel on public roads.

Such a regulation would set minimum standards to ensure that the vehicles display basic skills and competence in traffic situations where their manufacturers want to use them, said Henry Liu, who leads the University of Michigan’s autonomous vehicle testing center.

“Ensuring safety is important for consumers, for autonomous vehicle developers, for the federal government as well,” Liu said in an interview. “The federal government has the responsibility to help set the minimum standard, to help provide guidance in terms of safety testing."

In recent years, autonomous vehicles have been involved in a number of high-profile crashes, and surveys have revealed widespread public uncertainty about their safety. Successful testing of the vehicles' ability to master a variety of traffic situations, Liu suggested, would strengthen the public's confidence in them.

Liu said significant research is still needed before autonomous vehicles could be rolled out safely nationwide. But he said he agreed with their manufacturers that in the long run, self-driving vehicles could potentially save lives and improve the efficiency of the nation's transportation system.

At present, no specific federal regulations cover self-driving vehicles, and only a
