Can a Modified Rear Lip Pass the Annual Vehicle Inspection?
2 Answers
Generally, modified rear lips cannot pass the annual vehicle inspection. Relevant regulations: Vehicle modifications must be carried out in compliance with applicable laws and regulations; otherwise, they may fail the annual inspection. Therefore, it is advisable for car owners to consult in advance whether the intended modifications are legal before proceeding. Modification scope: The vehicle model, engine model, and chassis number cannot be altered, and the vehicle structure must not be compromised. Changing the vehicle color, replacing the engine, body, or chassis requires inspection of the vehicle. Additionally, a safety technical inspection certificate must be submitted for engine, body, or chassis replacements. Installing windshields, radiators, toolboxes, spare tire racks, front and rear anti-collision devices, or adding interior decorations requires registration for modification.
Last time I modified the rear lip of my car, and it really got flagged during the annual inspection. The inspector said there were too many external modifications, and the overall shape of the vehicle had changed, which could easily affect safety testing. I quickly went to the 4S dealership to replace it with the original rear bumper parts, and only then did I pass smoothly. I’ve come to understand that the annual inspection mainly checks whether the frame structure is original, the position of the lights, and safety performance. Even minor decorative modifications like a rear lip, if non-compliant, will be rejected outright by the inspection station. My advice to friends who want to modify their cars is to either consult local inspection standards in advance or use detachable, non-destructive modifications to avoid wasting money and time. Now, before every annual inspection, I double-check the exterior of my car to ensure there are no unnecessary modifications—it saves both hassle and money.
