Apollo Go robotaxis stall on Wuhan highways, triggering major jams and fresh safety scrutiny

What happened

It has been reported that at 20:57 on March 31 multiple Apollo Go autonomous taxis operated by Baidu (百度) suddenly halted on major roads and elevated expressways in Wuhan, including the city's Second Ring Road and Third Ring Road. The Wuhan Municipal Public Security Bureau’s Traffic Management Bureau issued a police report saying the stoppages occurred simultaneously across several busy corridors, creating significant congestion and forcing traffic authorities to deploy personnel to manage the snarls. Passengers and other motorists were reportedly delayed for hours as traffic ground to a near standstill.

Why it matters

Robotaxi pilots are meant to prove that autonomous driving can relieve congestion and expand mobility. What happens when an entire fleet freezes on elevated expressways? The event underscores two hard truths for China’s fast-moving AV sector: real-world complexity still outstrips lab performance, and system failures can have city-scale consequences. It has been reported that local regulators have opened inquiries; Baidu did not immediately respond to requests for comment, and it has been reported that investigations are ongoing.

Wider context

Baidu’s Apollo Go is one of China’s most prominent commercial robotaxi services and a showcase of Beijing’s ambition to commercialize autonomous mobility at scale. The incident arrives amid tighter regulatory scrutiny in China over safety and data controls for high-risk AI applications, and against a geopolitical backdrop where export controls on advanced chips and AI tools complicate hardware and software sourcing. Reportedly, such supply-chain and regulatory pressures add urgency to demonstrating robust, fault-tolerant systems.

Can a technology that promises to reduce accidents and congestion withstand the realities of crowded Chinese megacities? For policymakers, investors and the public, Wednesday’s stoppage will sharpen the debate over how quickly — and how safely — autonomous fleets should be allowed to expand.
