Window tinting in Massachusetts
Massachusetts holds front and rear glass to 35%. A ceramic at that shade is the honest way to deal with a hot cabin.
In Massachusetts, front side windows must let at least 35% of visible light through. Rear glass must let at least 35% of visible light through. Windshield film stays a clear strip at the top, not a full tint. House and storefront film is not held to that driving rule. This is a summary of published limits, not legal advice.
