Is It Illegal to Install a Rear Spoiler on a Car?

[Judy]

Installing a rear spoiler on a car is not illegal. Here is more information about car spoilers: Introduction to Car Spoilers: A car spoiler refers to the ducktail-like protrusion installed at the rear end of the car's trunk lid. It is part of the car's aerodynamic kit and primarily functions to reduce lift at the rear of the vehicle. Important Notes: When modifying a spoiler, the car owner must file a record with the vehicle management office in advance. After the modification is completed, the owner must also take new photos to update the images on the vehicle registration certificate. Functions: It effectively reduces the air resistance generated when the car is driving at high speeds. It offsets some of the lift, controls the car's upward float, reduces the impact of wind resistance, improves driving stability, and enhances the car's aesthetic appearance.
