Maine Window Tint Laws: Complete Legal Guide
Window tinting can enhance your vehicle's appearance and provide UV protection, but Maine has specific regulations you need to follow. Breaking these laws can result in fines, failed vehicle inspections, and the requirement to remove your tint. Understanding Maine's tint laws before you visit a shop ensures you stay compliant while protecting your investment.
Quick Reference Table
| Window | Legal VLT % | Notes |
|---|---|---|
| Front Windshield | 70% | Only non-reflective tint above AS-1 line permitted |
| Front Side Windows | 50% | Minimum 50% light transmission required |
| Rear Side Windows | Unlimited | Any darkness allowed |
| Rear Window | Unlimited | Any darkness allowed |
Understanding VLT (Visible Light Transmission)
VLT percentage measures how much visible light passes through your tint. A 70% VLT rating means 70% of sunlight passes through the tint, while 30% is blocked. The lower the percentage, the darker the tint—but darker isn't always legal. Maine's regulations prioritize driver safety by requiring lighter tints on windows that affect your ability to see and be seen.
Think of VLT like sunglasses: dark sunglasses block more light (lower VLT), while regular glasses let most light through (higher VLT). Your car windows have legal limits just like there are regulations for driver vision standards. Knowing your state's VLT limits helps you choose tint that looks great without triggering a violation.
Front Windshield Rules
Maine allows non-reflective window tint on your front windshield, but only above the AS-1 line. The AS-1 line is a manufacturer-marked line (or an imaginary line two inches below the top of the windshield if unmarked) that indicates where you can safely apply tint without obstructing the driver's view. Your tint on this upper section must have a VLT of at least 70%, meaning it can only be very light tinting.
The reasoning behind this restriction is clear: your front windshield is critical for safe driving. Maine law wants to ensure maximum visibility while still allowing some light protection in the upper portion of the glass.
Side Window Rules
Maine's rules for front and rear side windows differ significantly. Your front side windows (driver and passenger windows) must have a minimum VLT of 50%, which means they can be moderately tinted—dark enough to provide privacy and UV protection, but light enough to maintain visibility for you and law enforcement.
Rear side windows, however, have no darkness restrictions in Maine. You can apply any darkness level to your rear windows, including limo tint or complete blackout. This flexibility gives drivers options for privacy and style on the rear half of the vehicle while maintaining safety-critical visibility up front.
Rear Window Rules
Like the rear side windows, Maine places no restrictions on rear window tinting darkness. You're free to apply any VLT percentage, including completely opaque tint. This applies equally to sedans and SUVs. The only requirement is that if your vehicle is equipped with dual exterior mirrors (which most modern cars are), you have more freedom since the law recognizes that rear visibility isn't solely dependent on the rear window.
Restricted Colors
Maine does not restrict specific tint colors like red, amber, or blue. You can legally apply any color tint to your windows as long as you meet the VLT requirements outlined above. However, reflective or mirror-like tints are prohibited on the front windshield and front side windows. Your tint should be non-reflective on windows where VLT limits apply, meaning it shouldn't look like a mirror or have a metallic sheen that causes glare.
Medical Exemptions
Maine does not have a formal statewide medical exemption program for darker window tinting. Drivers with medical conditions requiring light protection should consult with a dermatologist or ophthalmologist and consider alternative UV protection methods such as lightweight long sleeves, protective hats, or medical-grade sunscreen.
If you believe you have a legitimate medical need for darker tinting, document it with a licensed physician and contact your local Maine Department of Motor Vehicles office. While not guaranteed approval, having medical documentation may provide grounds for discussion, though Maine law does not guarantee exemptions. Always verify current regulations with the DMV before applying tint beyond the legal limits.
Penalties for Illegal Tint
Law enforcement in Maine can issue citations for illegal window tinting during traffic stops. While specific fine amounts vary by county and circumstances, violations typically result in fines ranging from $100 to $500. More importantly, vehicles with illegal tint will fail Maine's vehicle inspection, preventing registration renewal.
If cited, you'll likely receive a fix-it ticket (a conditional citation) giving you time to remove the non-compliant tint and return for re-inspection. Once you remove the tint or bring it into compliance, you can have your vehicle re-inspected at any authorized inspection station. It's much easier and cheaper to get your tint right the first time than to deal with violations and removal costs later.
