Traffic police in Luzhou, Sichuan, said a man lost control of his vehicle in a crash that left two people dead and three injured.
Investigators have ruled out drunk driving and drug driving as factors in the case, narrowing the early public explanation to loss of control rather than intoxicant-related offenses.
Officials have not framed the incident beyond those points. The confirmed toll and the exclusion of alcohol and drugs remain the core facts released so far.
