Cruise, General Motors' self-driving vehicle subsidiary, just got its license suspended. The California Department of Motor Vehicles revoked Cruise's permits to test and operate fully driverless vehicles on California roads, the agency said in a statement Tuesday.

The suspension applies only to vehicles with no "safety driver," meaning there is no one in the driver's seat ready to take over the controls if needed.

"Based upon the performance of the vehicles, the Department determines the manufacturer's vehicles are not safe for the public's operation," the agency said in a notice posted to its website.

The agency also indicated that Cruise had "misrepresented... information related to safety of the autonomous technology of its vehicles."

For those reasons, the California DMV wrote, it was necessary to revoke the company's permits. The DMV notice did not specify exactly what incidents or communications from Cruise led to the suspensions.

About three weeks ago, a Cruise vehicle hit a pedestrian in downtown San Francisco who had first been hit by another vehicle then and was propelled by this collision into the path of the Cruise driverless car. After striking the pedestrian a second time, the Cruise vehicle, attempting to pull off the road and out of the way of traffic, dragged the pedestrian along the road for a short distance, according to Cruise.

"Our thoughts continue to be with the victim as we hope for a rapid and complete recovery," Cruise wrote in an emailed statement. A San Francisco Fire Department spokesperson said at the time that victim had multiple serious injuries.

This was the incident that ultimately precipitated the DMV to revoke the permits, according to an emailed statement from Cruise.

Cruise claims that it proactively reached out both state and federal safety regulators following that incident. Regulators at the National Highway Traffic Safety Administration opened an investigation into the safety of Cruise autonomous vehicles around pedestrians.

"The DMV has provided Cruise with the steps needed to apply to reinstate its suspended permits, which the DMV will not approve until the company has fulfilled the requirements to the department's satisfaction," the agency sad in the notice posted to its web site.

This summer, Cruise and Waymo, the driverless car arm of Google-parent Alphabet received permission from San Francisco regulators to begin regular paid driverless taxi services in that city.

Cruise will continue operations of its driverless fleets in Phoenix, Arizona and Austin, Texas.
