Does the bid change violate industrial and commercial laws and regulations? The logo of a car is the brand of the car. From the perspective of business administration, brands can't be changed casually, and whoever changes them will constitute infringement of other people's trademarks. But changing the logo seems a little different. First of all, the reporter asked the industry department of the municipal government and the Municipal Administration for Industry and Commerce. They all said that there is no regulation on whether private cars can be exchanged, and it is not clear whether this is illegal. People in the traffic control department said that they don't know much about this situation, and they don't care if they change the logo when checking the vehicles. A senior person engaged in industrial and commercial laws and regulations explained this. He said that because it is not a commercial act for consumers to change their cars into another logo, and it is not for profit, it does not constitute infringement, which is also the fundamental reason why the management department cannot eradicate the phenomenon of changing logos. The car decoration shop explains this: this is also a form of car beauty. The original logo is damaged and needs to be replaced. The client asked me to change the license plate. What reason can I not give it? There is no such provision. Does the bid change have an impact on traffic management? People in the traffic police department said that if the driver drives illegally, we mainly check the driver's license and the license plate of the car. Changing the logo really has no effect on traffic management. However, Mr. Zhang from the laboratory of the Municipal Vehicle Management Office said that this kind of behavior is not allowed by government departments. He said that the inspection station has encountered many times, such as replacing the original Golden Shield domestic car logo of Accord 2 2L with Honda. In this case, the annual inspection cannot be passed, because the photos on the driving license contain the brand of the car, and changing the logo itself violates the regulations. Later, Mr. Zhang said that since the rebranding of cars is mostly the personal behavior of consumers to satisfy vanity, rebranding does not affect the comprehensive performance of cars. After the competent authorities find this situation, they will generally let the owners change themselves, and there is no fine. But if the degree of modification affects the whole car, it depends on the situation and will be punished.
