A professional traffic lawyer said: "Many car owners are indifferent to changing the logo privately, but in fact it is an illegal act." Although the act of changing the logo without permission is only a minor punishment in our country, the owner who changed the logo and the merchants who produced and sold the logo without permission violated the Trademark Law, which constituted trademark infringement and harmed the rights and interests of the brand owner of the logo. According to the first paragraph of Article 50 of the Regulations for the Implementation of the Trademark Law, "on the same or similar goods, using marks identical with or similar to other people's registered trademarks as commodity names or commodity decorations, misleading the public" is an act of infringement of the exclusive right to use registered trademarks. In fact, changing the logo without permission infringes on the exclusive right to use a registered trademark representing the product image standards and quality requirements. After installing the logos of other brands, it is likely to damage the image of the products represented by the logos and affect the image of the brands in the public mind.

In addition, it is common for car owners to change the logo, which will make the theft of the logo more serious. Nowadays, many logos hanging on low-end cars are stolen from other famous cars, and the resale of logos has virtually become the best way for thieves to sell stolen goods, which is extremely unfavorable to social security management.

China's "Technical Conditions for Motor Vehicle Operation Safety" stipulates that when a motor vehicle is modified or repaired, destructive operations such as vehicle code, vehicle model and factory number, engine model and factory number, component number and product label shall not be covered, blocked, polished, repaired or padded. The Measures for the Administration of Motor Vehicles also stipulates that if there are changes in motor vehicle registration, the owner must go through the corresponding change procedures at the vehicle management department. After pointing out the serious harm of changing the logo without authorization, the traffic control department advised the owner not to blindly change the logo. In addition, Article 90 of China's Road Traffic Safety Law stipulates that those who illegally modify motor vehicles shall be fined below 200 yuan.
