Percentages are the minimum visible light transmission with the film installed, including the factory glass. A lower number means darker tint.
Is 5%, 20%, 35% or 50% tint legal in Delaware?
This table shows whether a film with each rating is legal on a sedan in Delaware. Factory glass blocks some light, so a film reads darker once it's installed.
| Film rating | Front side windows | Back side windows | Rear window |
|---|---|---|---|
| 5% | Not legal | Legal | Legal |
| 15% | Not legal | Legal | Legal |
| 20% | Not legal | Legal | Legal |
| 35% | Not legal | Legal | Legal |
| 50% | Likely too dark once installed | Legal | Legal |
| 70% | Legal | Legal | Legal |
'Likely too dark once installed' means the film rating meets the limit, but on typical factory glass the combined reading usually falls under it. Meter the window to be sure.
Choosing a film that stays legal
Assume factory side glass passes about 80% of light.
- Front side windows: 65% film or lighter
- Back side windows: Any film
- Rear window: Any film
Factory privacy glass on many SUVs already reads well under 30%, so any film added over it will read darker still. Always meter after the install.
Fines and penalties
Delaware's tint law doesn't set a specific fine. Amounts are set by the court where the ticket is issued.
Medical exemptions
Carry a signed statement from a licensed physician or optometrist verifying the tint is medically necessary.
