1. Changing the logo without authorization infringes on the exclusive right to use the registered trademark of a brand-name automobile. Because the registered trademark represents the image standard and quality requirements of its products, changing the logo of a low-grade car into the logo of a famous car will have an impact on the image and reputation of a famous car. As the user of the infringing trademark, the owner uses other people's famous automobile trademarks without permission, which also constitutes infringement.

It is illegal to modify the vehicle label without authorization. According to the Road Traffic Safety Law, it is illegal to change the car logo without permission. According to the relevant motor vehicle registration management regulations, vehicles cannot be changed at will after registration in the vehicle management office.

At present, the law has no severe punishment for bid change, and it can only impose a fine of 20~200 yuan and order it to be restored to its original state. At the same time, it must not pass the vehicle inspection, because it is a modified part, and it is impossible to judge the model after the standard change.

Article 16 of the Road Traffic Safety Law No unit or individual may commit any of the following acts:

1, assembling a motor vehicle or changing the registered structure, structure or characteristics of a motor vehicle without authorization.

2, change the motor vehicle model, engine number, frame number or vehicle identification code.

3. Forge, alter or use forged or altered motor vehicle registration certificates, number plates, driving licenses, inspection marks and insurance marks.

4. Use the registration certificate, license plate, driving license, inspection mark and insurance mark of other motor vehicles.

The behavior of changing the standard can be considered as changing the characteristics and models of motor vehicles without authorization.
