Is it illegal to put advertising slogans on a car?

[AndersonFitz]

Unapproved and unregistered vehicle body advertisements are illegal. They become legal only after registration. However, no advertisements are allowed on the front, sides, or rear windshield of the car, as this can easily obstruct the driver's view and affect safe driving. During vehicle inspections, any advertisements on the windshield will be required to be removed; otherwise, the vehicle will not pass inspection. Additionally, painting or pasting advertisements on the vehicle body must comply with regulations and require the completion of vehicle appearance modification procedures at the vehicle management department. Advertisements on the vehicle body are only permitted on the sides of the car, outside the window glass. Advertisements are not allowed on the front and rear windshields, the front hood, or the trunk lid.
