I often get asked by friends which car modifications don't require registration. From my experience, interior modifications generally don't need registration, such as changing seat covers, adding a steering wheel cover, or laying floor mats—as long as they don't alter the original car structure or safety equipment. Also, exterior modifications like small stickers or decals are fine if they don't obstruct vision or cover too much area. Adding practical accessories like dash cams, phone holders, or USB charging ports is also acceptable. However, avoid modifying the engine or exhaust system, as that might involve registration issues. Changing the style of wheels and tires is fine if you keep the original size. When making these simple modifications, it's best to choose reputable brands—safety comes first. Since regulations occasionally update, it's wise to check local traffic rules to confirm. This way, you can enjoy customizing your car without worrying about fines.

As someone who often helps others with car repairs, I recommend considering which minor modifications don't require registration first. For interior modifications, items like floor mats, sunshades, and trunk organizers can be installed directly. For exterior modifications, roof racks under 30cm in height or small antennas don't need registration. Among functional parts, dash cams and tire pressure monitoring systems are the most convenient and safe options. However, avoid modifications like overly bright lighting or chassis alterations that might cause trouble. Steer clear of any modifications that affect driving safety, such as headlight color changes that don't meet standards. I recommend adding small decorations during routine maintenance for low cost and minimal risk. It's crucial to check the latest regulations to avoid tickets for minor issues. Keeping it safe can also make your car more functional.

I like to add some personality to my car without needing to register the changes. Changing the seats to new leather, adding floor mats, or modifying the interior is all fine. Applying a small body sticker or adding fog light frames is also okay. Installing a phone holder or dash cam is absolutely free. Just remember not to exceed the legal wheel size limits. For safety, avoid modifying the main electrical system. These minor modifications are cost-effective and hassle-free, so I recommend starting with the interior.
