No, 50% window tint is illegal in New Hampshire. State law mandates front side windows allow 35% light transmittance, while rear windows may be darker if the vehicle has side mirrors. Violations risk fines up to $250 under RSA 266:89.
Key Regulations for 50% Window Tint in New Hampshire
- Front side windows must permit 35% or greater light transmittance; 50% fails compliance.
- Rear side and rear windows may exceed 35% tint if the vehicle has dual side mirrors, but front windows remain restricted.
- Medical exemptions require a physician’s certification submitted to the DMV, with tint levels capped at 35% for front windows.
New Hampshire’s 2026 regulatory review may tighten enforcement, particularly for aftermarket tints exceeding front-side limits. Local law enforcement, including the NH State Police, actively cite violations during roadside inspections. Dealers and installers face liability for non-compliant tint installations. Always verify tint percentages with certified equipment, as discrepancies often trigger penalties.
