June 18, 2018—A self-driving vehicle operated by Waymo was involved in a crash Saturday night in Mesa, Ariz., USA Today reports.
The five-car collision happened about 10 p.m. Saturday.
The self-driving van was not in autonomous mode at the time of the crash, said a spokesperson for the Mesa Fire and Medical Department.
Police believe the driver, who was arrested, was impaired at the time of the crash.
Waymo vehicles have become more prevalent throughout the Phoenix area and the southeast Valley since parent company Google brought the self-driving-car project to Chandler, Ariz.
"Our team's mission is to make our roads safer—it is at the core of everything we do and motivates every member of our team. We are concerned about the well-being and safety of our test driver and wish her a full recovery," the company said in a statement.
An autonomous Uber vehicle struck and killed a pedestrian in Arizona back in March. Since, the company has shut down autonomous testing in the state.
