Is photochromic window film legal to use while driving?
Photochromic window tint legality varies by country and state. In its clear state (70% VLT), the film typically meets or exceeds most jurisdictions' legal minimum for side and rear windows. When darkened to 25% VLT under UV, it may exceed limits in some regions. We recommend consulting local traffic laws before installation. As a Guangzhou-based China factory, we supply photochromic film globally and can provide VLT certification documentation for customs and compliance purposes upon request.
