Installing a front splitter on a car requires applying for modification registration with the public security authority management department. Here is relevant information: 1. Penalty: Unregistered modifications are considered illegal. Depending on the situation, it may also require updating the driver's license for registration. If the front splitter modification fails to pass the approval process, traffic police will impose corresponding penalties. 2. Specific regulations: Adding a front splitter is a decorative modification. As long as it is registered with the vehicle management office, it is not considered illegal, and traffic police generally won't stop you. Illegal modifications mainly refer to exaggerated color changes, body kits, exhaust pipe modifications, engine model changes, etc.

I've specialized in studying automotive modification regulations. Installing a front splitter falls under altering the vehicle's appearance and generally requires registration filing. Our country's "Motor Vehicle Registration Regulations" clearly state that any modifications changing the vehicle's length/width/height technical parameters or significantly affecting appearance must undergo procedures at the DMV. Since front splitters are installed below the front bumper, altering the original shape, registration is absolutely mandatory. A friend of mine installed a carbon fiber splitter last year without filing - failed inspection outright and got a 200 yuan traffic police fine. Don't gamble on this - only official channels ensure road legality. Just spend half a day at the DMV for photos and application - it's worry-free and safe.

I also installed a front splitter on my car, and the registration process was actually quite simple. Just bring your vehicle license and ID card to the local DMV. The staff will first take photos of the modified car for records, then you fill out a modification registration form, pay a fee of a few dozen yuan, and that's it. The key is to ensure your modifications don't exceed regulations—for example, the front splitter shouldn't protrude more than 5 cm from the body, and reflective strips must not block the license plate. Nowadays, some areas have relaxed policies, and minor modifications that don't affect safety might be overlooked by traffic police. However, during strict inspections, they can still penalize you for illegal modifications. Before making any changes, I recommend checking the local DMV's official website or calling to confirm, so you don't waste your effort.

My friends in the car modification circle have talked to me about this. The key actually lies in the material and size of the front lip. Those thin rubber front lips are usually fine, but exaggerated carbon fiber body kits definitely require registration. During vehicle annual inspections, there's an exterior check item, and I've seen people being asked to remove the front lip on the spot to pass. Traffic police typically focus on two points when inspecting modifications: whether they affect lighting and ground clearance. If the front lip is too low and blocks the fog lights, or if metal parts are used, reducing the ground clearance to less than 15 cm, it's definitely considered illegal modification. After modification, be sure to keep the official invoice from the modification shop as proof in case of inspection, to show that it's not a substandard product.
