An Act To Amend Title 21 Of The Delaware Code Relating To Tinting Of Motor Vehicle Windshield, Windows, Or Side Wings.
SB255 amends Delaware’s motor vehicle window-tinting law in Title 21. The bill updates the standards for tinting on windshields, front side windows, side wings, rear side windows, and rear windows by tying compliance to federal safety standard FMVSS 205 and by clarifying where tint may be applied. It allows transparent tint along the top edge of the windshield so long as it does not intrude into the AS-1 portion, and it sets a visible light transmission threshold of 50% or greater for tint on the front side windows and side wings. It also clarifies that tint on windows behind the driver and on the rear window may be applied with 0% or greater visible light transmission, meaning there is no minimum light-transmission requirement for those windows.
The bill preserves and clarifies several existing exceptions. It continues to exempt medically necessary tint when supported by a statement from a licensed medical practitioner, osteopathic physician, or optometrist. It also exempts antique motor vehicles, street rods, and vehicles insured under antique/classic/street rod policies. In addition, it exempts police K-9 unit vehicles, surveillance vehicles operated by police officers, and vehicles operated by law-enforcement officers, while limiting the exception so it does not apply to marked vehicles except police K-9 units and certain unmarked patrol vehicles.
In practical terms, SB255 would change how Delaware enforces window-tint compliance for drivers and vehicle owners, especially for the front windows where the bill lowers the required light transmission from the prior 70% standard to 50% in the substitute version. It would also make the statute clearer for law enforcement and the Division of Motor Vehicles by specifying the federal standard, the medical exemption, and the categories of vehicles that are not subject to the rule. The bill affects motorists, tint installers, law enforcement agencies, and DMV enforcement practices.
The general sentiment reflected in the bill materials is supportive and clarifying rather than controversial. The substitute bill appears designed to modernize and standardize the tinting rules while preserving safety and enforcement exceptions. The main policy choice reflected in the substitute is a compromise on the front-window tint threshold: the synopsis states that the substitute changes the front-side-window and side-wing requirement from 35% or greater in the original bill to 50% or greater. That suggests the principal point of contention was how dark front-window tint should be allowed to be, balancing driver preference, privacy, and medical needs against visibility and traffic safety concerns.
No committee transcript or vote record was provided, so there is no documented floor or committee debate in the supplied materials. Based on the text alone, the bill’s most notable issue is the degree of allowable tint on front-facing windows and the scope of exemptions for medical, antique, and law-enforcement vehicles.
SB255 would amend Title 21, Section 4313 of the Delaware Code governing window tinting and federal safety glass standards. It would lower the allowable visible light transmission for tint on front side windows and side wings to 50% or greater, clarify that rear side windows and rear windows have no minimum visible light transmission requirement, and expressly exempt certain law-enforcement vehicles and officers from the statute. The bill would also preserve medical, antique vehicle, and street rod exceptions, affecting motorists, tint installers, police agencies, and DMV enforcement of vehicle equipment standards.
The bill appears generally favorable and technical in nature, with the substitute version indicating a negotiated or moderated approach to the tint threshold. The synopsis suggests the measure is intended to clarify existing law and update standards rather than create a major new restriction. The shift from a 35% threshold in the original bill to 50% in the substitute suggests some balancing of competing interests, but no vote or transcript data is available to show opposition or support from specific lawmakers or stakeholders.
The main point of contention is the allowable darkness of tint on front side windows and side wings. The substitute bill raises the threshold from 35% or greater in the original bill to 50% or greater, indicating disagreement over how much tint should be permitted while maintaining visibility and safety. Secondary issues include the breadth of exemptions—especially for law-enforcement vehicles, medical necessity, and antique/classic vehicles—but the text suggests these were largely preserved rather than disputed.
