China's Baidu has been granted a licence to test its Apollo autonomous vehicles in Hong Kong, marking the company's first known permit for autonomous vehicle testing outside mainland China. The licence allows Baidu Apollo International Ltd to conduct trials for 10 autonomous vehicles in North Lantau. The trial will initially involve one self-driving car operating on specified road sections, with a backup operator on board. Baidu plans to expand its robotaxi service, Apollo Go, to more countries and regions outside mainland China.
