Uber halted its autonomous vehicle development program March 24 after a crash in Tempe, Arizona flipped one of its Volvo XC90 test mules onto its side, reports Motoring, but resumed operation late March 27.

The incident took place Friday after a vehicle failed to yield to Uber’s autonomous SUV, turning in front of it instead of waiting for a larger gap in traffic.

Uber has confirmed its vehicle was running in full-autonomous mode at the time of the crash.

The ride-share company reported it had two “safety drivers” on board at the time of the crash, but it appears they failed to intervene until it was too late to avoid the collision.

“We are continuing to look into this incident and can confirm we had no backseat passengers in the vehicle,” said an Uber spokeswoman after the crash.

Thankfully, neither the safety drivers on-board the Volvo nor the occupants of the other vehicles involved in the crash sustained any injuries.

More than 100 self-driving XC90 development vehicles have been rolled out by Uber in a $400-million joint-development project with Volvo.

Uber partnered with Volvo to develop its autonomous vehicle technology with the ultimate aim of creating fleets of driverless ride-share vehicles in multiple cities around the world.
