The California Department of Motor Vehicles suspended General Motors’ Cruises’ autonomous vehicle deployment and driverless testing permits across the state, citing safety concerns and incidents.

“When there is an unreasonable risk to public safety, the DMV can immediately suspend or revoke permits,” California DMV wrote in a press release.

DMV’s suspension was based on several factors, including “manufacturer’s vehicles are not safe for the public’s operation” and “manufacturer has misrepresented any information related to the safety of the autonomous technology of its vehicles.”
