Will traffic police interfere with car spoiler modifications?

[ArabellaDella]

According to China's 'Motor Vehicle Registration Regulations', modifiable car items include: changing the body color (must register the change at the vehicle management office within 10 days), replacing the engine (same model, must register the change at the vehicle management office within 10 days), replacing the body or frame (must register the change at the vehicle management office within 10 days). Small and micro passenger vehicles can install front and rear anti-collision devices, while freight vehicles can add windshields, water tanks, toolboxes, spare tire racks, etc., and enhance interior decorations. Therefore, the answers to the questions are as follows: 1. Installing a small spoiler on a car is legal, so traffic police will not interfere. However, if a more exaggerated large spoiler is installed, it must be registered in advance at the vehicle management office. 2. Illegal modifications include replacing the vehicle's exterior wrap, changing the original car logo, altering engine performance, removing seats inside the car, etc.
