The NHTSA said on Wednesday that it has closed its probe into Cruise robotaxis in light of the company ceasing business operations.

The National Highway Traffic Safety Administration’s Office of Defects Investigation has closed their preliminary investigation into General Motors' (NYSE:GM) Cruise division and will take no further action.

U.S. auto safety regulators on Wednesday closed a probe into whether General Motors’ self-driving unit Cruise robotaxis were taking sufficient precautions to safeguard pedestrians.

US auto safety regulators ended a federal investigation into Cruise robotaxis without taking action, removing an overhang weeks after General Motors Co. decided to shutter the struggling business.

The agency said it analyzed 2,759 reports identified by Cruise that involved collisions, including 1,113 that involved a “pedestrian conflict.”
