I've been trying to figure this text out in NHK news easy: http://www3.nhk.or.jp/news/easy/k10010447431000/k10010447431000.html
There is a part when it says: トラックなど１２台の車がぶつかる事故がありました。 I couldn't understand this トラックなど１２台の車 exactly, the order of the words are confusing me I think. I'm reading "truck 12 cars", and I don't know what this など is doing. I think the overall meaning is "one truck and twelve cars", but I want to know exactly which role each word is playing. Could someone explain this part to me?
