There are many reasons car owners in New Hampshire want to get their windows tinted. In addition to giving the car a sharp look, tints help maintain privacy and they block sunlight, glare, heat, and a large proportion of UV rays.

New Hampshire allows window tinting for vehicles with set parameters for transparency levels. Tint laws in New Hampshire originally came into force in 1990. Since then, many amendments have been made to the law.

A bill was recently signed that raised acceptable transparency levels for tinted car windows.

The law was backed by the state’s police because of how important it is to be able to identify drivers and passengers from outside the vehicle. The law was too lenient before.

All 50 states in the United States have their own rules and regulations concerning car window tints. These rules take into consideration the type of vehicle and window placement. They also make room for certain exemptions.

Below we outline exactly what the requirements of this law are.

Permitted Window Tint Darkness

Window tint darkness levels affect visibility. This level of darkness is measured with the help of a unit called VLT or visible light transmission.

The VLT percentage will determine how much visible light can make it through the tinted window and into the car cabin.

The smaller the value of VLT, the darker the tint is. For instance, a car window with a 15% VLT tint is significantly darker than a tint with 40% VLT.


Windshield: A non-reflective tint with 70% VLT is permitted for those with a medical waiver. The previously acceptable level was 35% VLT.
Driver-side windows: Tint darkness cannot be less than 70% VLT.
Passenger-side windows: Tint darkness can’t be less than 35% VLT.
Rear window: The permitted level of darkness must not be less than 35% VLT.

Acceptable Tint Reflection

Applying tint film on windows bars a certain amount of light from entering the vehicle. It also reflects some of that light depending on its reflective nature.

Tint reflection differs from tint darkness. While the former bounces off visible light when it hits the surface, the latter allows only a specific percentage of light to get through.

New Hampshire does not allow the use of reflective tints.
