PITTSBURGH — Attorneys for the Pennsylvania Public Utility Commission have asked a panel of judges to force two ride-share companies to stop operating in Pittsburgh.

The Pittsburgh Post-Gazette reports the PUC’s enforcement arm argued Thursday that Lyft and Uber are violating state rules that govern paid transportation services.

Uber, Lyft and other ride-share companies use smartphone apps to dispatch drivers who use their own personal vehicles.

PUC enforcement officer Charles Bowser testified at a hearing in Pittsburgh that allowing the services to operate without state oversight is a “recipe for disaster.”

The companies are fighting the PUC’s request for a cease-and-desist order.

Administrative Law Judge Mary Long says a decision will be issued by July 1.
