Bill > HB720

This bill modifies Hawaii's regulations regarding window tinting for motor vehicles by reducing the allowable light transmittance for vehicle windows from 35% (plus or minus 6%) to 25% (plus or minus 5%). The bill's rationale is rooted in Hawaii's tropical climate, which experiences intense sunlight, high temperatures, and significant glare. The legislature argues that more permissive window tinting will provide several benefits, including increased driver and passenger comfort, reduced interior vehicle temperatures, improved driving safety by minimizing glare, protection from ultraviolet light, and prevention of sun damage to vehicle interiors. The proposed changes specifically apply to sun screening devices for front side wing vents, windows to the rear of the driver, and rear windows, while maintaining existing exemptions for certain vehicle components like rearview mirrors, sun visors, and specific sticker placements. The bill will take effect immediately upon approval, allowing for a quick implementation of the new window tinting standards.
