The [PA] state Public Utility Commission issued a statement Thursday calling for “vigorous public discussion” on rules for self-driving vehicles. Uber can operate its self-driving vehicles with passengers as long as it doesn’t charge a fee, but it would need PUC approval once it begins charging.

“Any business offering transportation services to the general public for compensation must secure proper authority from the PUC before beginning that service, and clearly demonstrate the technical ability to operate safely,” the PUC statement said. “To date, no entity has applied for such authority in Pennsylvania, and the Commission has not authorized any use of fully autonomous vehicles for transportation services that fall under the jurisdiction of the PUC.”
