On February 11, 2025, the Hawaii House of Representatives introduced House Bill 368 (HB368), aimed at amending existing regulations on sun screening devices for motor vehicles. The bill seeks to provide exemptions for individuals with light sensitivity due to medical conditions, allowing for greater flexibility in the use of window tinting.

The primary provisions of HB368 include adjustments to the allowable light transmittance percentages for sun screening devices. Specifically, the bill proposes that individuals with documented medical conditions can use sun screening materials that permit a light transmittance of no less than 20 percent. This is a significant reduction from the current standard, which requires a minimum of 35 percent light transmittance for front side windows and rear windows necessary for driving visibility.

Notably, the bill outlines that individuals must provide updated documentation from a licensed physician every two years to qualify for these exemptions. Additionally, it mandates that any side windows tinted beyond the specified limits must be rolled down during traffic stops.

The introduction of HB368 has sparked discussions among lawmakers and stakeholders regarding the balance between safety regulations and the needs of individuals with medical conditions. Proponents argue that the bill addresses a critical health issue, allowing those with light sensitivity to drive safely without compromising their well-being. Conversely, some lawmakers express concerns about potential misuse of the exemptions and the implications for road safety.

The bill's economic implications could also be significant, as it may lead to increased demand for specialized window tinting services tailored to meet the new standards. Furthermore, the legislation could set a precedent for similar measures in other states, potentially influencing national discussions on vehicle safety and accessibility.

As HB368 progresses through the legislative process, its future remains uncertain. The bill is scheduled for further review, and its outcomes will depend on ongoing debates and potential amendments. If passed, the law is set to take effect on July 1, 3000, marking a long-term commitment to addressing the needs of individuals with light sensitivity in Hawaii.
