Is my tint legal here?

Film darkness and glass darkness multiply. Enter the film you are considering and the VLT of the bare glass to get the number a meter would read.

70 for tinted OEM glass, 80 for clear

Net VLT 14% 20% film × 70% glass

    Pass/fail compares net VLT against the limits on this page only. Some states apply a measurement tolerance — see Measurement tolerance below — and none of this replaces a meter reading on your own glass.

    Notes

    Statute text fetched directly from delcode.delaware.gov confirms the FMVSS 205 compliance requirement, AS-1 line rule, medical exemption, antique-vehicle/street-rod exception, and a law-enforcement-officer exemption; it did not give a standalone numeric VLT figure independent of the FMVSS 205 cross-reference (secondary sources commonly cite ~50% front-side / no floor on rear as the practical effect of following FMVSS 205, but this specific number was not seen verbatim in the fetched statute excerpt). No back-side/rear VLT figure or reflectivity number was present in the retrieved text.

    Delaware tint questions

    What is the darkest legal tint in Delaware?

    For a sedan in Delaware, front side windows must let at least 50% of light through, no number is stated for the back side windows, and none for the rear window. Lower VLT means darker glass, so those percentages are floors, not targets, and the meter reads the film and the factory glass together.

    Is 20% tint legal in Delaware?

    No, not on the front side windows. Delaware requires at least 50% VLT there and 20% is darker than that, before you even account for the factory glass, which makes the reading darker still. Behind the driver the statute states no VLT number, so 20% may be allowed on the back side and rear windows — read the notes on this page and confirm with the DMV.

    Can I tint the windshield in Delaware?

    Delaware's rule for the windshield: Must meet FMVSS 205 (49 CFR 571.205); non-windshield-area material at top edge permitted only if transparent and outside the AS-1 portion

    Does Delaware allow a medical exemption for darker tint?

    What the source says: yes - statement signed by a licensed physician (medicine/osteopathic/optometry) verifying tinted windows are medically necessary, carried by owner/usual operator Confirm the current process with the agency named before you have film installed.
