Uber has pulled the plug on its self-driving car operation in Arizona two months after a pedestrian was killed in an accident involving one of its cars.
However, the ride-hailing company said it hopes to resume self-driving tests in Pennsylvania this summer.
The firm said it was committed to self-driving technology and “looked forward to returning to public roads”.
It comes as the firm reported a huge jump in bookings for its main taxi business for the three months to March.
Uber gives drivers sick pay and parental leave
Uber began testing its first self-driving cars in Pittsburgh, Pennsylvania in 2016, gradually expanding to other places, including Arizona, San Francisco, California and Toronto.
It halted all those operations in March after the crash, which sparked debate about the readiness and safety of driverless car technology.
Jobs lost
The firm is also conducting a “top-to-bottom safety review” of its self-driving programme, including software and training.
Uber hopes to resume tests this summer in Pittsburgh after federal officials conclude their investigation of the accident.
After that, it will look at other locations.
About 300 workers for the firm’s self-driving programme in Arizona will lose their jobs. The more than 500 employees of its traditional taxi service in Arizona are not affected.
