Uber suspended its pilot programme for driverless cars after an accident in the US at the weekend, it has been reported.
The Telegraph said a vehicle equipped with the technology crashed in Tempe, Arizona on Saturday.
Although the accident left the Uber vehicle on its side, the ride-hailing company and local police said it caused no serious injuries.
However, Uber said it was grounding driverless cars involved in a pilot programme in Arizona, Pittsburgh and San Francisco pending the outcome of an investigation into the crash.
According to a spokeswoman for the Tempe Police Department, the accident occurred when the driver of a second vehicle ‘failed to yield’ to the Uber vehicle while making a turn.
Uber said two 'safety' drivers were in the front seats of its car, which was in self-driving mode at the time of the crash.
Update: An Uber spokesperson told Transport Network on Monday evening (morning in the US): 'We are resuming our development operations in San Francisco this morning.'
'We are continuing to look into this incident and can confirm we had no backseat passengers in the vehicle.'
