US ride-hailing company Uber has suspended its self-driving cars from the roads after an accident involving one such vehicle, the media reported on Sunday.
A self-driven Volvo SUV owned and operated by Uber Technologies Inc. is flipped on its side after a collision in Tempe, Arizona on March 24, 2017.
Pictures posted online showed the car on its right side on a street in Arizona, next to another badly damaged vehicle, the BBC reported.
The car - a Volvo SUV - was in self-driving mode at the time of the crash, on Friday, Uber said in a statement on Saturday. No one was injured.
A police official said the accident occurred when the other vehicle "failed to yield" to the Uber car at a left turn.
"There was a person behind the wheel. It is uncertain at this time if they were controlling the vehicle at the time of the collision," the official said.
"We are continuing to look into this incident and can confirm we had no backseat passengers in the vehicle," an Uber spokesperson told Khaleej Times in an email.
Uber's self-driving cars always have a human in the driving seat who can take over the controls.
The company pulled its self-driving vehicles off the road in Arizona at first, followed by test sites in Pennsylvania and California-all three states where it operated the vehicles.
