an act of a car being officially removed from a place where it has been illegally left

I couldn't find a parking meter, so I decided to park illegally and risk a tow-away. 我找不到停车收费器，所以我决定冒着车子被拖走的危险违章停放。

This part of town is a tow-away area/zone (= one in which cars left illegally will be removed). 城镇的这一地区是非停车区，违规停放的车辆会被拖走。
