You cannot tint your car windows before getting license plates, as it may affect the registration process. Detailed explanation of why you cannot tint windows before registration: Incorrect tint color (e.g., too dark) may affect license plate registration. The vehicle's driver's compartment must ensure the driver's forward and side visibility. The visible light transmittance of the windshield and other glass areas in the driver's line of sight must not be less than 70%. Mirror-like reflective sunshade films are prohibited on all window glass. Precautions for car window tinting: Avoid rolling windows up and down for three days after tinting; For vehicles with sunroofs, avoid opening the sunroof while driving, especially at high speeds, during the first three days; In winter, it's recommended not to roll windows up and down or wash the car for one week after tinting. The front and rear window tints may take about a month to fully dry.

I researched this when buying a car before, and found it's best not to rush into window tinting before license plate registration. Vehicle registration requires passing strict inspections, including window light transmittance tests. Most regions mandate that the windshield must have at least 70% light transmittance, and side windows must also maintain clarity. If you install dark or low-quality tints prematurely, they may fail to meet standards, forcing you to remove them for retesting - wasting hundreds of yuan and multiple trips. Post-registration tinting is much more convenient. Quality tints provide UV protection, heat insulation, privacy, and extend interior lifespan. Safety is crucial too - dark tints impair night driving visibility and increase accident risks. Always choose certified tint brands that comply with light transmittance regulations. Don't cut corners - handle tinting only after plate installation to avoid unnecessary troubles.

As a newbie when I first bought a car, I wanted to apply window tint for sun protection. But friends warned me not to do it before getting the license plate. The DMV inspection checks the original window condition - if the tint is too dark, it won't pass the test. Then you'd have to remove the film and reapply, wasting time and adding extra costs. It's better to wait until after getting the plates to apply a standard-compliant light tint that blocks sun without obscuring road visibility. Tinting is indeed useful - it blocks UV rays to reduce interior aging and enhances privacy. But doing it prematurely can cause complications. Following regulations saves hassle. Safety and cost-efficiency should come first.

With years of experience in car modification, including extensive expertise in window tinting, I can attest that applying tint before vehicle registration carries significant risks. The DMV conducts strict inspections, particularly regarding light transmittance—for instance, the windshield must allow over 70% light transmission. Failure to meet this standard may result in rejection, forcing you to remove and reapply the film, potentially damaging the windows. A wiser approach is to wait until after registration to apply high-quality, compliant tint. This minimizes redundant efforts and unnecessary expenses. While tinting offers benefits like UV protection, heat reduction, and enhanced privacy, timing is crucial—misjudging it can backfire.
