Uber's self-driving cars are back on the road Thursday, nine months after a fatal accident in Arizona stalled development and pushed the company into lengthy reviews.

The company says it conducted a "top-to-bottom" audit of its safety policies. It previously vowed to improve operations before returning self-driving vehicles to the road. Uber pulled all testing in March, after one of the company's autonomous vehicles struck and killed a pedestrian.
