The Ministry of Public Security yesterday named and shamed nine provinces for atrociously high levels of drunk driving, the South China Morning Post reported. The provinces identified were Yunnan, Sichuan, Gansu, Heilongjiang, Inner Mongolia, Tibet, Xinjiang, Guangxi and Henan. The report was based on aggregated survey data from traffic checks, which found that an average of 20% of drivers in the above provinces were legally drunk. "In some individual places, the offending rate was near 40%," a notice on the ministry’s website said. The investigation also said the highest number of drunk driving cases were in the wealthier provinces and coastal cities. The investigation was conducted as part of a new campaign against drunk driving launched on August 12, prompted by several recent fatalities caused by drunk driving highlighted by domestic media. Last month a man in Chengdu, Sichuan was sentenced to death for killing four people, the mainland’s first death sentence for drunk driving. On August 17 in Henan, another man was sentenced to six-and-a-half years in prison and fined US$280,000 after killing six and injuring another six in January. Despite the campaign, the ministry said there has been no "obvious drop" in drunk driving cases.
