The Uber vehicle was reportedly headed northbound when a woman walking outside of the crosswalk was struck.
The woman, identified as 49-year-old Elaine Herzberg, was taken to the hospital where she died from her injuries.
Tempe Police says the vehicle was in autonomous mode at the time of the crash and the vehicle operator, 44-year-old Rafaela Vasquez, was also behind the wheel. No passengers were in the vehicle at the time.
An Uber spokesperson told ABC15 they are aware of the incident and are cooperating with authorities.
The case will be reviewed by the Maricopa County Attorney's Office.
Governor Doug Ducey's office released the following statement on the incident:
We are aware of the accident. Our prayers are with the victim, and our hearts go out to her family. Our office is in communication with law enforcement. Public safety is our top priority, and the Governor's latest Executive Order provides enhanced enforcement measures and clarity on responsibility in these accidents.
Tempe Mayor Mark Mitchell tweeted the following statement:
Uber began testing self-driving cars in Tempe in February 2017. The fleet of self-driving Volvos arrived in Arizona after they were banned from California roads over safety concerns. Gov. Doug Ducey touted Arizona as a testing ground, saying at the time in a written statement, “Arizona welcomes Uber self-driving cars with open arms and wide open roads.”
