LOS ANGELES, March 28 (Xinhua) -- Uber returned its self-driving cars to roads on Monday following a crash involving one of Uber's self-driving SUV taxi three days ago.
The ride-hailing company resumed testing on Monday in Tempe, San Francisco and Pittsburgh the northeastern U.S. state of Pennsylvania, according to local media reports.
On Friday, the company temporarily suspended its pilot program in the three cities after a crash, in which a human-driven vehicle "failed to yield" to an Uber vehicle while making a turn in Tempe, Arizona, according to the police department.
Video from the scene showed that the vehicles collided, causing the autonomous vehicle to roll onto its side.
The Uber car was in the self-driving mode at the time of the crash. There were no passengers in the self-driving Volvo XC90 at the time of the incident. And there were no serious injuries.
Uber brought its fleet of self-driving cars to Arizona last year following a dispute with the California Department of Motor Vehicles. The company officially kicked off its self-driving pilot program in February in Tempe with Arizona Governor Doug Ducey taking the first passenger ride.
