Window Tint laws in Maine
Maine Revised Statutes Title 29-A, §1916 sets the regulations for vehicle window tinting. The law generally permits tinting on side windows behind the driver and the rear window, provided the light transmittance is not less than 35%. Tinting on the windshield is prohibited below the AS-1 line or more than 5 inches from the top of the windshield. Tinting on the front side windows (driver and passenger) is also generally restricted to prevent obstruction of the driver's clear view of the highway and any vehicle to the side. There are specific exemptions for medical conditions, which require a physician's certificate to be carried in the vehicle. The law allows a vehicle to have tint applied to any window behind the driver, including the rear window, as long as the light transmittance is at least 35%. For front side windows, the tint cannot be darker than that permitted by federal regulations for original equipment, which typically means very light or no tint. This ensures that law enforcement and other drivers can see into the vehicle, promoting safety. Non-compliance can result in a traffic infraction, and the vehicle may not pass inspection until the tint is removed or brought into compliance. Repeat offenses or significant violations could lead to more severe penalties.
