Is Installing a Rear Spoiler on a Car Illegal?

[VonMiles]

Adding a rear spoiler is not considered a violation. If the modification does not exceed 60% of the vehicle's body area, there is no need to apply for a change registration with the traffic management department. However, if it exceeds 60%, it is mandatory to register the changes; otherwise, the vehicle will not pass the annual inspection. Below are the relevant legal provisions: According to Article 10 of the "Regulations on the Registration of Motor Vehicles," the owner of a registered motor vehicle shall apply to the vehicle management office at the place of registration for a change of registration under any of the following circumstances: 1. Change of the vehicle body color; 2. Replacement of the engine; 3. Replacement of the vehicle body or frame; 4. Replacement of the entire vehicle due to quality issues; 5. Change of use nature, such as converting a commercial vehicle to a non-commercial vehicle or vice versa.
