Jiangxi Crash: Driver Used Smart Driving Before Crash

An investigation report into a fatal rear-end collision on the Jiguang Expressway in Ganzhou, Jiangxi Province has revealed that the driver of a Changan Qiyuan A07 electric sedan activated the vehicle’s smart driving assistance system and removed both hands from the steering wheel approximately 40 seconds before impact. The crash, which occurred in the early hours of October 2, 2025, killed all three occupants of the sedan and has reignited debate over the safety boundaries of L2-level driver assistance systems in China.

According to the report released by the Ganzhou Emergency Management Bureau, the sedan was traveling north-to-south on the expressway in the early morning hours when it rear-ended a heavy semi-trailer truck that had stalled in the left fast lane. The truck had run out of fuel after its driver failed to switch between main and auxiliary fuel tanks.

What the Investigation Found

Event Data Recorder (EDR) analysis conducted by Changan Automobile Co., Ltd. revealed a detailed sequence of events. The sedan driver, identified as Zhang, exited the Ningdu East Service Area shortly before the crash. He actively activated the IACC (Integrated Adaptive Cruise Control) function — the vehicle’s L2-level smart driving assistance mode — approximately 40 seconds before impact. EDR data shows the vehicle was in a hands-off-steering-wheel state for 13 seconds leading up to the collision, and the driver did not press the accelerator or brake pedal during the final five seconds. No evasive action was taken.

As reported by New Yellow River via East Money, the truck driver, identified as Tan, had stalled in the left lane after his vehicle ran out of fuel. The truck’s rear lights were not illuminated, and reflective markings were missing, damaged, or obscured. Tan placed four warning cones behind the truck, but the farthest was less than 45 meters — far short of the legally required 150 meters. The truck frame had also been illegally lengthened by 5,170 mm.

Responsibility and Legal Consequences

The investigation found both drivers bore direct responsibility for the accident. The sedan driver, Zhang, was found to have failed to detect road conditions ahead and take effective evasive measures while using the smart driving assistance system at night. Because he died in the accident, he was exempted from punishment. The truck driver, Tan, has been subjected to criminal compulsory measures by judicial authorities.

The report also recommended administrative penalties for the truck’s owner, Yunyi Yunqing (Yangzhou) Transportation Co., Ltd., for safety violations and illegal operations, and for Xiamen Shunyuantai Trading Co., Ltd., which illegally modified the trailer. Three unnamed public officials have been referred for accountability investigation.

The Technology Question

The Changan Qiyuan A07 is equipped with the “Tianshu Driving Assistance” system, featuring 5 millimeter-wave radars, 12 ultrasonic radars, and 5 cameras — 22 perception sensors in total. The vehicle’s advertised safety features include Forward Collision Warning, Automatic Emergency Braking (AEB), and Lane Keeping Assist.

However, as National Business Daily reported, the scenario of a stationary vehicle at night without lighting or reflective markings is widely regarded by the automotive industry as one of the most challenging operating conditions for current L2 systems. Multiple automakers and technical materials have indicated that assisted driving systems cannot fully identify stationary obstacles in all scenarios.

When contacted by New Yellow River, Changan Qiyuan customer service did not directly answer whether the system could accurately identify a stationary, unlit vehicle ahead at high speed. The representative stated the issue would be recorded and a technical specialist would call back within 24 hours — a response that had not been received by the time of publication.

Regulatory Implications

The crash occurred while China’s first mandatory national standard for L2-level assisted driving was still in draft form. Published for public comment in September 2025, the standard — “Safety Requirements for Intelligent Connected Vehicles — Combined Driving Assistance Systems” — is expected to take effect in January 2027. It would classify L2 systems into three categories and impose requirements including disabling the system if the driver’s hands or eyes leave the road for excessive periods.

Broader Context

The Changan Qiyuan A07 sold 53,862 units in 2025, making it a leading model in China’s mid-to-large car segment. The case has drawn widespread public attention, with online discussions highlighting divided views: many blamed the driver for over-reliance on technology, while others expressed concern that frequent use of such systems leads to complacency.

The economic loss from the accident is estimated at approximately 4.29 million RMB (roughly US$590,000).

What’s Next

As China’s automotive industry pushes toward higher levels of automation, the Jiangxi crash serves as a stark reminder of the gap between marketing claims and real-world system capabilities. The forthcoming mandatory standard may address some of the vulnerabilities exposed by this tragedy, particularly around driver monitoring. However, questions remain about whether automakers will face liability or product recall actions, and whether the public’s trust in assisted driving technology can be rebuilt.
