Three people were killed and more than 20 people are being hospitalized as the result of a huge Shanghai expressway pileup last week.
The accident occurred on a day of particularly thick smog and heavy traffic in the midst of the Spring Festival peak travel time.
Police said that a car hit a truck in front of it while driving on the expressway, and the car behind it was unable to brake in time, leading to an 11-car collision. Casualties are still on rise.
