Arizona has suspended Uber's self-driving car tests in the state following a fatal crash involving one of the company's autonomous vehicles.
Arizona Gov. Doug Ducey sent a letter on Monday to Uber CEO Dara Khosrowshahi informing him of the decision.
According to the letter, Ducey said he found video footage of the crash "disturbing and alarming." He said it raised "questions about the ability of Uber to continue testing in Arizona."
Police in Tempe released a 22-second video showing a woman walking from a darkened area onto a street just before an Uber SUV strikes her. The Volvo was in self-driving mode with a human backup driver at the wheel when it struck 49-year-old Elaine Herzberg, police said.
In a response to the letter, an Uber spokesman noted that the company had quickly pulled all its autonomous vehicles from the roads following the accident.
"We proactively suspended self-driving operations in all cities immediately following the tragic incident last week," the spokesman told CNN on Monday. "We continue to help investigators in any way we can, and we'll keep a dialogue open with the governor's office to address any concerns they have."
A self-driving Uber Volvo XC90 SUV struck and killed 49-year-old Elaine Herzberg as she walked her bicycle across a street in Tempe on March 18, according to police. A test driver from Uber was behind the wheel of the car at the time.
The Tempe Police Department and the National Transportation Safety Board have launched investigations into the crash.
Uber's recent crash has spurred greater scrutiny of the self-driving vehicle industry across the country. Last week, Boston's government asked self-driving companies operating in the city to halt operations while safety procedures were reviewed.
