The window of the traffic control department of Hohhot Municipal Affairs Service Center can not only handle all business related to vehicle management, but also handle tax, license plate and other business. In the past, when people bought a car, they had to pay taxes and get insurance, and then they went to the traffic control department to register the car before they could drive on the road. The business of tax, insurance and traffic control departments should be handled in at least three places, while the one-stop service hall can handle all the business in one place and at different windows. Each window will inform the citizens who come to handle business in detail, which window to go to next, and what procedures are needed. The one-stop service of the traffic control department started from the trial operation in July and officially provided services to the public in August. Among them, the motor vehicle inspection area can handle the registration business of small ordinary cars, small new energy vehicles and ordinary motorcycles (including imported cars, domestic cars, household registration, motor vehicle change and motor vehicle transfer registration).
