Is Adding a Rear Spoiler Legal?
1 Answers
Installing a rear spoiler on a car is an illegal modification. If the vehicle's body shape does not match the photo on the registration certificate, the car will not pass the annual inspection. More details about adding a rear spoiler are as follows: 1. According to the "Motor Vehicle Registration Regulations," for any registered motor vehicle, if changes are made to the body color, model, performance, purpose, or structure, or if the frame, body, or engine is replaced, the owner must apply for a modification registration with the local vehicle management office. In principle, adding a rear spoiler is not allowed. 2. Rear spoilers were originally installed on aircraft to enhance stability, prevent significant vibrations during flight, and control flight attitude, making them the most critical component of an aircraft's flight control system. Many cars, such as the Audi A7 and Porsche 911, also feature rear spoilers. A car's rear spoiler not only improves the vehicle's overall aesthetics but also enhances stability. Rear spoilers are typically installed on coupes or sports cars, and they are not recommended for family sedans—even small spoilers are prohibited. 3. Vehicle modifications are subject to restrictions. After modifying a car, the owner must update the vehicle's registration certificate photo at the local traffic management office. Failure to do so may result in penalties from traffic police. Modifications can also affect the vehicle's annual inspection. Some modifications, such as interior changes or car pendants, are legal as long as they do not obstruct the driver's view.
