Is it okay to post car advertisements?

Is it okay to post advertisements on the car? It is ok to post advertisements on the car body, as long as it does not exceed 30% of the car body and does not affect safe driving: 1. Car body advertisements that are not approved for filing are illegal, and will only be legal after registration. However, advertisements cannot be posted on the front, side and rear windshields of automobiles, which will easily block the driver's sight and affect safe driving. 2. During vehicle inspection, if advertisements are pasted on the windshield, they will be required to be removed, otherwise the vehicle inspection will not pass. If advertisements are sprayed or pasted on the vehicle body, the vehicle body appearance change procedures must be handled at the vehicle management department according to regulations; 3. Advertisements on the car body are only allowed to be posted on both sides of the car body except the window glass. Advertisements shall not be posted on the front and rear windshield, front hood and trunk lid of the car, and the advertising area shall not exceed 30% of the car body. @20 19
