PITTSBURGH (AP) — Mayor Bill Peduto is defending two ride-sharing companies that the Pennsylvania Public Utility Commission’s Bureau of Investigation and Enforcement has threatened with fines and cease-and-desist orders.

The PUC filed the cease-and-desist orders Monday against San Francisco-based ride-share companies Lyft and Uber. The companies and others like them use smartphone apps to dispatch drivers who use their personal vehicles to give passengers rides for a fee. The PUC contends the companies are operating illegally as transportation brokers and that the drivers are not licensed as motor carriers and may not be properly insured.
