According to Article 16 of the Road Traffic Safety Law of the People's Republic of China, no unit or individual may assemble a motor vehicle or change the registered structure, structure or characteristics of a motor vehicle without authorization. Therefore, the modification of a vehicle into an RV has involved changing the structure and characteristics of the vehicle, and driving on the road will be punished. All modified cars need to be registered at the vehicle management office. The scope of legal modification in China is basically acceptable, such as wheel hub, color, local painting (not more than 30%), exterior decoration (which will not affect the obvious characteristics of the vehicle), interior decoration (seat is not allowed to be disassembled), variable valve exhaust, anti-collision beam, etc. However, it is still necessary to apply for change registration, otherwise it will be regarded as illegal modification.
