Can a small spoiler pass the annual inspection?

Adding a spoiler to a car will not pass the annual inspection. During the annual vehicle inspection, the vehicle will be checked for modifications, alterations, or transformations. The inspection will verify if the vehicle's registration, license plate, and vehicle records match the actual condition of the vehicle and if any changes have been made, as well as whether the necessary approval and modification procedures have been completed. Unless the vehicle has undergone modifications, alterations, or technical transformations without the required approval and modification procedures. Relevant information about the annual vehicle inspection is as follows: Introduction: The annual vehicle inspection is a mandatory test for every vehicle that has obtained an official license plate and registration certificate. It is equivalent to an annual physical examination for the vehicle according to the "Technical Conditions for the Safe Operation of Motor Vehicles." Purpose: The annual vehicle inspection can promptly eliminate potential safety hazards, encourage better vehicle maintenance, and reduce the occurrence of traffic accidents.

I added a small spoiler to my car and surprisingly passed the annual inspection, but this isn’t absolute—it depends on the region and specific regulations. In my city, where enforcement is relatively lax, the small spoiler wasn’t flagged as an issue. However, legally speaking, any modification counts as altering the vehicle’s structure and could be classified as non-compliant. The spoiler was mainly for aesthetics, but if installed poorly, it could disrupt aerodynamics, leading to unstable driving or increased fuel consumption. My advice: if you really want one, opt for a small, low-profile design, ensure it’s securely installed, and check with the local DMV about registration requirements before the inspection to avoid last-minute removal hassles. While small spoilers often slip through, for peace of mind, it’s best to avoid unnecessary exterior modifications.
