The Uber vehicle was in autonomous mode with a human safety driver at the wheel when it struck the woman, who was crossing the street outside of a crosswalk, the Tempe police said in a statement. The episode occurred overnight, although the authorities did not specify whether it was late Sunday or early Monday. The woman was not publicly identified.
An Uber spokeswoman said the company was “fully cooperating” with the local authorities. The company said it had suspended testing of its self-driving cars in Tempe, Pittsburgh, San Francisco and Toronto.
