No, 15% window tint is illegal in Massachusetts under state regulations, which cap front-side windows at 35% light transmittance. Local police enforce this strictly, and the Registry of Motor Vehicles (RMV) may reject registrations for non-compliant vehicles. Violations risk fines up to $250 per offense, with potential vehicle inspection failures.
Key Regulations for 15% Window Tint in Massachusetts
- Front-side windows must allow at least 35% light transmittance; 15% tint fails this requirement.
- Windshield tinting is prohibited except for a non-reflective strip above the AS-1 line.
- Rear windows may have darker tint (up to 35% on sedans, 65% on SUVs/vans) but require compliance stickers from the RMV.
The Massachusetts RMV enforces these rules via annual inspections, aligning with the 2026 federal safety standards that prioritize visibility. Local authorities, including the Boston Police Department, conduct random roadside checks, particularly in high-tint complaint areas. Aftermarket tint installations must be documented with a compliance certificate or face penalties.
