The bill amends sections of the General Laws regarding nontransparent windshields and windows, specifically focusing on the allowable levels of light transmittance for vehicles. It establishes that front side windows and front side wing vents must have a light transmittance of at least 32%, as measured with a light transmittance meter having an accuracy of plus or minus 3%. Additionally, the bill specifies that the right and left side windows behind the driver and the rearmost window must also meet the same light transmittance requirement.

The bill outlines exemptions from these regulations, including windows behind the driver on trucks, motor buses, trailers, mobile manufactured homes, or multipurpose passenger vehicles, provided the vehicle is equipped with outside mirrors that allow the driver to see the highway for a distance of at least 200 feet to the rear. It also allows for the rearmost window or windows to be exempt under similar conditions.

The bill removes previous provisions regarding the use of nontransparent materials and introduces new criteria for exemptions, such as the requirement for outside mirrors on vehicles to ensure adequate rear visibility. The act is intended to align state law with Connecticut's regulations on nontransparent windshields and windows and will take effect upon passage.
