Tempe police are investigating a fatal crash between a self-driving Uber car and a pedestrian.

Tempe Police says the vehicle was in autonomous mode at the time of the crash and a vehicle operator was also behind the wheel. No passengers were in the vehicle at the time.

Uber has paused self-driving operations in Phoenix, Pittsburgh, San Francisco and Toronto, which is a standard move, the company says.

Bloomberg notes the woman was crossing the road outside of a crosswalk when the Uber vehicle, operating in autonomous mode under the supervision of a human safety driver, struck her, according to the Tempe Police Department.
