Modifying a car grille can pass vehicle inspection, as it is merely a change in the vehicle's exterior color, but it requires filing and registration with the vehicle management office. The items inspected during the annual inspection include: 1. Checking whether the engine, chassis, body, and their accessories are clean, complete, and functional, whether the paint is uniform and aesthetically pleasing, whether the main assemblies have been replaced, and whether they match the initial inspection records; 2. Verifying whether the vehicle's braking performance, lights, exhaust, and other safety features comply with relevant regulations. Situations that may prevent passing the inspection include: 1. Discrepancies between the vehicle's condition and the records on the driving license or archives; 2. Damaged, incomplete, or illegible license plates or driving licenses, or self-made license plates; 3. Vehicles that have undergone modifications, alterations, or technical transformations without undergoing approval and change procedures; 4. Failure to display the unit name and enlarged license plate characters as required; 5. Improper installation of alarms or indicator lights.

I once wanted to change my car's grille to a cooler one, and it looked awesome after the modification. However, I ran into trouble during the annual inspection. The inspector said the modification altered the front appearance and didn’t comply with regulations—I almost failed. During inspections, they pay special attention to the car logo, safety markings, and original design, such as the grille position. Modifying it might obscure the manufacturer’s badge or exceed size limits. I ended up spending hundreds to revert it back to stock—what a waste of money. My advice to fellow car enthusiasts considering modifications: check the local DMV rules first or consult a professional shop to ensure it doesn’t affect safety markings. During regular maintenance, inspect these small details to avoid last-minute hassles during inspections. While modding is fun, don’t sacrifice compliance for a temporary aesthetic upgrade.

In my area, the annual vehicle inspection has strict requirements on the car's appearance. Modifying the grille often causes trouble because the DMV staff will check if the body appearance matches the factory specifications. I once knew a neighbor who installed an oversized grille and got rejected during the inspection, forcing him to spend money to restore it. This made me realize that the annual inspection is mainly about ensuring safety—key components shouldn't be altered without authorization, as it may affect accident identification or signal lights. I recommend consulting professionals before making modifications. Some minor changes, like not adding logos, might be tolerated, but rules vary by region, so don’t cut corners. After years of driving, I’ve learned that following regulations saves the most hassle—otherwise, it’s just a waste of time and energy.

If you're interested in modifying your car's grille, I must remind you that the annual inspection might be an issue, as they check the vehicle's body integrity during the inspection. I learned from a mechanic that modifying the grille, especially if it involves altering the logo or dimensions, could lead to rejection during the inspection—safety comes first. It's advisable to check the regulations first to ensure your modifications meet the standards, and avoid making reckless changes. The annual inspection isn't just about lights and brakes; the consistency of the vehicle's appearance also affects the outcome. If you want to save money on modifications, opting for detachable accessories is the safest bet—just switch back to the original parts before the inspection.
