Uber self-driving cars in Pennsylvania

Authorities in the US state of Pennsylvania have given Uber the green light to resume testing self-driving cars, the ride-sharing giant said Tuesday, after a fatal crash in Arizona prompted a pause. Uber said it had received authorization to put autonomous cars back on the road in Pittsburgh, where it has a lab devoted to the technology, but has yet to actually do so.

The San Francisco-based company suspended use of self-driving cars in March after one struck and killed a pedestrian in Tempe, Arizona. The Uber vehicle was in autonomous mode with an operator behind the wheel when it hit a woman walking in the street. In July, Uber said it was using cars with human drivers to test and improve autonomous capabilities.

The company, which is preparing to go public with an offering of shares next year, is in a self-driving car race with an array of companies including Alphabet-owned Waymo.
