You can install dust strips on a new car without license plates, but it is recommended to install them after obtaining the license plates, otherwise it may not pass the inspection. Overview of vehicle license plates: Vehicle license plates are hard-coded number plates with registration codes issued by vehicle authorities after reviewing, inspecting, and registering vehicles that have applied for plates, as stipulated by national vehicle management regulations with unified formats and styles. Legal documents: The vehicle registration certificate is issued by the vehicle management authority, recording the main contents of the vehicle's initial registration. It is kept by the owner, carried with the vehicle, and serves as a unified format registration booklet for recording changes and inspections at any time. According to the "Road Traffic Management Regulations," the vehicle license plate and registration certificate are the legal documents permitting the vehicle to drive on public roads.

Of course you can install dust seals! I installed door gap seals on my new car the very next day after picking it up. The dealership guy said such accessories that don't alter the vehicle's appearance won't affect license plate registration at all. However, I'd recommend avoiding overly flashy metal strips - plain black rubber ones are the safest bet. Remember to clean the door rubber seals thoroughly before installation, otherwise they might come off during highway driving. My best friend had installed ones with glitter before, and was asked to remove them during license plate registration - thankfully the inspection technician reminded her, saving her a wasted trip to the DMV.

As an office worker, I must remind you of the key point: Do not modify any exterior parts before the vehicle inspection! My experience is to wait until you get the official license plate before installing dust-proof strips. The new car registration photos require the vehicle to remain in its factory-original condition, not even window tinting is allowed. Once, my colleague was in a hurry to install door edge guards, and the DMV made him remove them on the spot. If you really want to install something, I suggest choosing pure rubber strips without logos, and keep the original packaging. If you're asked to remove them, you'll only lose a few dozen bucks. My car now uses 3M rubber strips, which make the door closing sound much more solid, and there's much less water accumulation on the threshold during rainy days.

A mechanic with 15 years of experience tells you: The dustproof strips can be applied right now. But there are three points to note: First, choose vehicle-specific models. Yesterday, I installed universal strips for a customer and they ended up peeling at the edges. Second, don’t cover the door’s production nameplate. Third, use high-quality, residue-free adhesive. Here’s a handy tip: After applying, expose the strips to strong sunlight for half a day to make the adhesive stronger. A Passat owner once placed the strips too far out, causing them to get squeezed off when closing the door, which actually let more dust in. In fact, the original door seals are well-designed, and adding extra strips has limited dust-reduction effects—it’s more of a psychological comfort.

After installing the dust strips on my right after applying PPF, it doesn't interfere with license plate installation at all. The key is positioning: stick the upper edge along the door frame without covering the VIN, and place the lower edge along the sill trim avoiding the chassis number area. Remember to wipe off the new car wax with wet wipes first, and wait until the door frame is completely dry before application. Found an unexpected benefit when installing child seats - the dust strips block door frame gaps, preventing kids' fingers from getting stuck. For best adhesion, install while the car's plastic parts are still new and haven't aged - older cars may not stick as well. Even if temporarily removed for inspection, they won't leave adhesive marks.

As a seasoned car enthusiast with 20 years of experience, let me be honest: don't make any modifications before your vehicle inspection! Back when I installed rain guards on my Civic, the DMV gave me trouble. Nowadays, while dust seals aren't considered modifications, enforcement standards vary by region. If you really want to install them, my advice is: choose soft TPE material instead of hard plastic; keep the width under 1.5 cm; and install them immediately after the DMV takes photos for the safest approach. My current car has them on all four door gaps, and I can personally attest that they reduce door sill mud by 70% during rain, keeping my pants legs completely free of black marks.
