AN ACT TO AMEND TITLE 21 OF THE DELAWARE CODE RELATING TO TINTING OF MOTOR VEHICLE WINDSHIELD, WINDOWS, OR SIDE WINGS.
Summary
Currently, window tint or other material placed on the front side windows of a motor vehicle must have a visible light transmission of 70% or greater unless the vehicle’s owner has a statement signed by a licensed practitioner of medicine and surgery or osteopathic medicine or optometry verifying that tinted windows are medically necessary. Currently, there is not a visible light transmission requirement for the side windows behind the driver or the rear window. This Act is a substitute for Senate Bill No. 255. Like Senate Bill No. 255, this Act does all of the following: (1) Changes the visible light transmission requirement for window tint or other material placed on the front side windows. (2) Clarifies that there is not a visible light transmission requirement for the side windows behind the driver or the rear window. (3) Clarifies the exception for vehicles operated by a law-enforcement officer by exempting these vehicles from this law. This Act differs from Senate Bill No. 255 by changing the visible requirement for window tint or other material placed on the front side windows, and side wings, from 35% or great to 50% or greater.
