Is 5%, 20%, 35% or 50% tint legal in New Hampshire?
This table shows whether a film with each rating is legal on a sedan in New Hampshire. 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 with mirrors on both sides | Not legal |
| 15% | Not legal | Legal with mirrors on both sides | Not legal |
| 20% | Not legal | Legal with mirrors on both sides | Not legal |
| 35% | Not legal | Legal with mirrors on both sides | Likely too dark once installed |
| 50% | Not legal | Legal with mirrors on both sides | Legal |
| 70% | Likely too dark once installed | Legal with mirrors on both sides | 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: Clear or near-clear film (88% or lighter)
- Back side windows: Any film
- Rear window: 45% film or lighter
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.
