How dark can window tint be in New Hampshire?
Darkness is measured as visible light transmission (VLT): the percentage of light that gets through. A lower number means darker tint.
| Window | Cars | SUVs and vans |
|---|---|---|
| Windshield | A strip no wider than 6 inches at the top of the windshield is allowed if it lets in at least 35% of light. | |
| Front side windows | Must let in at least 70% of light. | |
| Back side windows | Must let in at least 35% of light. | Any darkness is allowed. |
| Rear window | Must let in at least 35% of light. | Any darkness is allowed. |

Law change Tint beside the driver now allowed at 70%
RSA 266:58-a, as published in 2025, allows aftermarket tint on the windows beside the driver if it lets in at least 70% of light, 35% on the rear windows, and a 6-inch windshield strip at 35% or more. Our 2011 records said no front tint was allowed. We don't know the exact year this changed.
