It is the operating vehicle that forcibly sprays words. As long as what you are driving is basically the nature of operating vehicles, you must spray words, so that law enforcement officers can quickly identify operating vehicles and facilitate inspection. As long as your 7-seater driving license is not an operating vehicle, you don't need to spray words.
