RELATING TO MOTOR VEHICLES.
HB844 would amend Hawaii’s motor vehicle window tinting law by lowering the minimum allowable light transmittance for certain sun screening devices from 35% (plus or minus 6%) to 25% (plus or minus 5%). In practical terms, the bill would permit darker window tint on front side windows and on rear side/rear windows that are subject to the statute, while leaving in place the existing exemptions for items such as mirrors, visors, windshield stickers, certain windshield sun strips, privacy drapes in motor homes, and tinting allowed under federal safety standards.
The bill’s stated rationale is that Hawaii’s tropical climate, increasing heat, glare, and ultraviolet exposure make current tint restrictions too strict and potentially harmful to comfort, health, and vehicle interiors. The measure is framed as a highway safety and public health adjustment, arguing that darker tint can reduce cabin temperatures, improve visibility by reducing glare, and protect occupants and property from sun damage.
If enacted, HB844 would directly amend section 291-21.5 of the Hawaii Revised Statutes by changing the legal threshold for permissible window tint on covered motor vehicles. It would reduce the required light transmittance standard for front side wing vents/windows and for rear side/rear windows used for driving visibility, thereby broadening the range of aftermarket tint products that would be lawful in Hawaii. The bill would affect drivers, vehicle owners, tint installers, and law enforcement officers responsible for enforcing window tint compliance, while preserving the statute’s existing exemptions and federal safety references.
The bill appears generally favorable in concept based on its framing, with the sponsor emphasizing comfort, safety, and health benefits in Hawaii’s climate. There is no recorded committee testimony or vote history in the provided materials, so there is no documented opposition or support from legislators, agencies, or the public in the available record. The bill was referred to TRN, CPC, and JHA, indicating it was still in the committee process at the time of the last action.
The main policy tension is between allowing darker tint for heat and glare reduction versus maintaining visibility and enforcement standards for roadway safety. Supporters would likely argue that the current 35% standard is too restrictive for Hawaii’s conditions, while potential opponents could raise concerns about reduced driver visibility, officer safety during traffic stops, and consistency with existing safety enforcement practices. No specific objections or named opponents appear in the provided transcripts or vote history.
