Frequently asked questions
What tint shade is legal in Maine?
Maine law generally requires side and rear windows to allow at least 35% light transmittance, measured as the glass and tint together. The law also says vehicle windows may not be reflective, and the front windshield cannot be treated in a way that reduces light transmittance beyond the original factory or replacement windshield, except for the allowed top windshield strip. Maine also has an exception for side windows behind the driver and rear windows when the vehicle has two outside rearview mirrors.Because every vehicle’s factory glass is different, the film percentage alone does not always tell the full story. We can help you choose a shade that looks great while keeping Maine inspection requirements in mind.
What does window tint percentage mean?
Window tint percentage refers to how much visible light passes through the glass. This is called VLT, or visible light transmission.A higher number means a lighter tint. A lower number means a darker tint.For example, 50% tint lets in more light and looks more subtle. 35% tint is darker but still has good visibility. 20% tint gives more privacy. 5% tint, often called limo tint, is very dark.The easy way to remember it: the lower the number, the darker the tint.
What does “35% net” mean?
“Net” means the final light reading after the tint is installed on the glass. Your vehicle’s factory glass may already have some built-in tint, so adding a 35% film does not always mean the finished window will test at exactly 35%.That is why it is important to consider both the film and the glass together. Maine’s law refers to light transmittance as the total of the glass and tint material, not just the film by itself.
Can I get 20% or 5% tint in Maine?
It depends on the window and the vehicle. For standard front side windows, darker shades like 20% or 5% are generally not the legal choice in Maine because front side glass needs to meet the 35% light transmittance requirement.Darker shades may be an option for rear side windows or rear glass in certain situations, especially when the vehicle has two outside rearview mirrors. We’ll talk through your options before installation so you know what is legal, what is practical, and what will look best.
Can I tint my windshield?
Full windshield tint is limited in Maine. The front windshield cannot be covered or treated in a way that reduces light transmittance beyond the original factory windshield or an original replacement windshield. Maine does allow sun-screening or tinting material above the AS-1 line, or along the top 5 inches of the windshield if there is no AS-1 line.That top strip is commonly called a windshield strip, brow, or sun strip. It helps reduce glare without darkening the full windshield.
What is the AS-1 line?
The AS-1 line is a marking near the top of many windshields that shows how far down a legal windshield strip can go. If your windshield does not have an AS-1 line, Maine law allows the strip along the top 5 inches of the windshield.
Do I need a tint certificate in Maine?
Yes, Maine requires a light transmittance certificate for vehicles with aftermarket tinted windows, and the owner or operator must show that certificate to the inspection mechanic at the time of inspection. Maine law also says a certificate may be requested by law enforcement, and failing to produce one creates a presumption that the vehicle does not meet the tint requirements.Keep your tint paperwork with your registration or inspection documents so it is easy to find when you need it.
What if I have a medical reason for darker tint?
Maine does allow medical exemptions in certain cases. The Maine State Police window tint medical exemption form requires certification from a Maine physician, physician assistant, or optometrist, and the exemption is tied to the medical condition and vehicle information.If you believe you qualify, you will need to follow the State’s exemption process. A medical exemption is separate from a standard tint installation.
Is ceramic tint a shade?
No. Ceramic tint is a type of film, not a darkness level.You can have ceramic tint in different shades, such as 50%, 35%, 20%, or 5%, depending on the film line and what is appropriate for your vehicle. Ceramic films are popular because they can offer better heat rejection, infrared reduction, glare control, and comfort without always needing to go extremely dark. 3M, for example, describes ceramic automotive film as using nano-ceramic technology for infrared heat rejection, and describes its ceramic films as targeting infrared heat while offering different shade options.
Does darker tint always block more heat?
Not always. Darker tint usually helps with glare and privacy, but heat rejection depends on the film technology, not just the shade.A high-quality ceramic film in a lighter shade may outperform a basic darker film when it comes to heat reduction. That means you can often stay cooler without making every window extremely dark. LLumar notes that ceramic tint options come in different shades and heat-rejection levels, while 3M’s Ceramic IR film is designed for infrared heat rejection and comfort.
What tint shade should I choose?
That depends on your goals.If you want a clean, legal, everyday look, 35% is a popular option for front side windows. If you want more privacy in the back, a darker rear setup may be a good fit depending on your vehicle. If heat is your main concern, ceramic film may be worth considering because performance matters just as much as darkness.We’ll help you balance appearance, comfort, privacy, visibility, and Maine’s legal requirements.
Will darker tint make it harder to see at night?
Yes, darker tint can reduce visibility at night, especially on back roads, in bad weather, or when backing up. Very dark tint may look sharp during the day, but it is not always the most practical choice for every driver.The best tint setup is the one that looks good, performs well, and still feels safe and comfortable when you’re driving after dark.
Can you match my factory rear tint?
In many cases, yes. Factory rear privacy glass is common on trucks, SUVs, and vans. We can usually help choose a front shade that complements the factory rear glass or add film over rear factory glass for more privacy and heat rejection.Factory privacy glass and aftermarket film are not the same thing. Factory glass may look dark, but it does not always offer the same heat rejection as quality window film.
Will my tint pass inspection?
Our goal is to help you choose a tint setup that keeps Maine inspection rules in mind. Maine law says an inspection certificate may not be issued if the vehicle does not meet the reflective and tinted glass requirements, so legal shade selection matters.Final inspection decisions are made by the inspection station, but choosing the correct shade and keeping your tint certificate helps avoid headaches later.
Why should I have my tint professionally installed?
Professional installation helps your tint look cleaner, cure properly, and last longer. A proper install also means better edge work, fewer imperfections, better film selection, and guidance on what shades make sense for your vehicle.Cheap tint can look good for a minute, then turn into a bubbling purple science experiment. Quality film and clean installation make a big difference.
