Surveillance footage captured the moment two trucks hit a wall and blocked the way in a section of tunnel on the Huyu Highway between Chongqing and Shanghai. A man got out of his sedan car after seeing the pile-up ahead, to try and warn other drivers in the tunnel.
Unfortunately the man was killed trying to help others, as cars and lorries behind him also crashed. Slippery conditions were blamed for causing the multi-vehicle pile-up.
