Window Tint Laws in New Hampshire
Laws change. Verify current requirements with your local DMV/RMV before choosing or installing film. This is not legal advice.
VLT is visible light transmission: lower percentages mean darker windows. A film's labeled shade is not necessarily the finished glass-plus-film reading. The limits below cover ordinary passenger cars unless stated otherwise.
- Front side windows
- At least 70% VLT.
- Rear side windows
- At least 35% VLT with both outside mirrors.
- Back window
- At least 35% VLT with both outside mirrors.
- Windshield strip
- Statute permits strip no wider than six inches at very top with at least 35% VLT; no other ordinary aftermarket windshield tint.
Vehicle class and conditions
Measurement basis: Combined glass-plus-film visible light transmission, not the film label alone.
SUV, van and multipurpose-vehicle rear sides: Statutory MPV/pickup rear exception follows pre-market glazing permissions under federal standard 205, not a universal aftermarket shade.
SUV, van and multipurpose-vehicle back window: Same statutory MPV/pickup exception and federal glazing conditions.
- DMV summary omits the statutory six-inch 35% strip and MPV/pickup exceptions; statute is cited alongside DMV.
- Medical authorization is separate; DMV describes at least 35% for authorized windshield/front sides.
