Uber suspends self-driving cars in two US states after crash
Uber has said its self-driving cars remain suspended in Arizona and Pittsburgh, Pennsylvania, following a crash over the weekend.
There were no serious injuries reported in the incident in Tempe, Arizona on Friday night.
Police said the self-driving Uber SUV was obeying the law while the human driver of the other car was cited for a moving violation.
Uber said it is investigating the incident, adding that there were no passengers in the back seat of the self-driving car.
Multiple car-makers and technology companies are testing fleets of self-driving vehicles.
In nearly all cases, the cars have backup drivers who can take the wheel in an emergency.
This is not the first accident involving a semi-autonomous car. Last year, a Tesla driver was killed with the car's Autopilot system engaged.
