Will traffic police regulate the installation of a rear spoiler on a car?

[AllieRose]

Installing a small rear spoiler on a car is not regulated by traffic police. However, if a more exaggerated large rear spoiler is installed, it must be registered with the vehicle management office in advance. Illegal modifications include replacing the vehicle's exterior panels, changing the original car emblem, altering engine performance, or removing seats inside the car. According to China's "Motor Vehicle Registration Regulations," the following modifications are allowed: 1. Changing the body color (must register the change with the vehicle management office within 10 days). 2. Replacing the engine (same model, must register the change with the vehicle management office within 10 days). 3. Replacing the body or frame (must register the change with the vehicle management office within 10 days). 4. Installing front and rear anti-collision devices for small and micro passenger vehicles, adding windshields, water tanks, toolboxes, spare tire racks, etc., for freight motor vehicles, or adding interior decorations to motor vehicles.
