The accident happened at the Changzhou section of the highway linking Shanghai and Nanjing．It drew public attention as people began posting photos and videos on Chinese social media WeChat and Weibo．Images showed dozens of trucks，buses and cars crashed into each other．People were standing on the top of the vehicles（运载工具）．

Local police told Xinhua Press that at least two trucks，three buses and 20 cars were involved．Rainy and foggy weather caused poor visibility and slippery mads．

What's more，it was difficult for ambulances（救护车）to get to the scene of the accident because the life emergency lane（生命通道）was filled with vehicles so that the doctors couldn't get there to save the injured．

The Ministry（部长）of Public Security told traffic departments nationwide to keep a look out for vehicles using the emergency lane occupancy．

All highways in China leave the right lane as the emergency lane．Some drivers，however，pay no attention to this rule．Therefore，the police call on drivers to follow the rule strictly and offer the injured more hope of being saved．
