Window Tint
29-A M.R.S. § 1916 — side and rear windows letting through at least 35% of the light
- No window may be reflective.
- The windshield may not let through less light than the original or original replacement glass, except tint above the AS-1 line or, without one, along a 5 inch strip at the top.
- A side or rear window may not let through less than 35% of the light, glass and film together.
- The windshield, the front door windows and the windows at either end of the rear seat let the occupants see the road and let a person outside see in.
Who handles this in Maine: legal aid programs and the state offices, listed in the Maine directory.
The side windows behind the driver and the rear window are exempt from the light and see-through rules when the vehicle has two outside mirrors, one on each side. The Chief of the State Police may grant an exemption when sunlight harms the health of the owner or a regular occupant; the certificate is shown when an officer asks.
An owner or operator with tinted windows gets a light transmittance certificate and shows it to the inspection mechanic at inspection.
