Bill > HB844

This bill modifies Hawaii's regulations on vehicle window tinting by adjusting the allowable light transmittance for sun screening devices, specifically reducing the permitted light transmission from 35% (plus or minus 6%) to 25% (plus or minus 5%). The legislative findings emphasize that Hawaii's tropical location results in intense sunlight, high temperatures, and significant glare, which can negatively impact driver comfort and safety. The bill argues that lower light transmission can help reduce interior vehicle temperatures, minimize glare, block harmful ultraviolet light, and protect both vehicle occupants and the vehicle's interior from sun damage. The proposed changes apply to front side wing vents, side windows to the rear of the driver, and rear windows, ensuring that when sun screening devices are used in conjunction with the vehicle's glazing material, they maintain at least 25% light transmittance (with a tolerance of plus or minus 5%). The bill maintains existing exemptions for specific vehicle components and screening applications, such as windshield sun screening along the top edge and screening materials meeting federal safety standards. The amendment will take effect immediately upon approval.
