Can a Sticker Spoiler Pass the Annual Inspection?
1 Answers
Sticker spoilers cannot pass the annual inspection. Although the "Motor Vehicle Inspection Work Regulations" have somewhat relaxed restrictions on vehicle modifications, spoiler modifications are not supported by policy. Installing a spoiler is considered an alteration of the vehicle's exterior and is illegal, so it is not recommended. Car spoilers are part of aerodynamic design and are commonly seen on various racing cars. Factory-installed spoilers on civilian vehicles are usually not overly exaggerated, and some even use retractable spoilers. When a car is driving at high speeds, the air passing over the spoiler can increase the vehicle's downforce (generally by several dozen kilograms, and in some cases even over 100 kilograms), improving driving stability. Additionally, a well-designed spoiler can reduce air resistance, contributing to fuel efficiency to some extent. Regardless of the size of the spoiler, even if you proactively report the modification to the traffic police department, you will only be ordered to restore the vehicle to its original condition. This is because the "Motor Vehicle Inspection Work Regulations" classify spoiler modifications as illegal alterations, which cannot be registered. If caught on the road, the traffic management department will impound the vehicle, confiscate the illegal device, order restoration, and impose a fine of 200 yuan as per the law.
