Maine window tint laws set the legal visible light transmission, or VLT, for each vehicle window. For most drivers, the key number is the front side window limit: 35%. Rear-window and windshield rules can change based on vehicle type, mirrors, medical authorization, and how the tint is measured.
Use this page to check the main legal tint limits in Maine, understand what the percentages mean, avoid common installation mistakes, and know what to verify before you respond to a citation or apply for a medical exemption.
Quick Navigation
Maine Legal Window Tint Limits
Important: A tint film percentage is not always the same as the final measured window percentage. Factory glass can already reduce light transmission, so ask for the final measured VLT after installation.
Maine Window Tint Law Table
| Window | Legal Limit | What It Means |
|---|---|---|
| Windshield | AS-1 line / top 5 inches | Windshield rules are usually stricter than side-window rules. Do not assume a dark windshield strip is legal without checking the state rule. |
| Front side windows | 35% | This is the most important compliance point because these windows affect driver and officer visibility. |
| Rear side windows | 35% | Rear side limits may differ for sedans, SUVs, vans, pickups, or multipurpose vehicles. |
| Rear window | 35% | Rear window tint may depend on outside mirrors or vehicle classification. |
| Reflective tint | not excessive | Mirror-like tint can create glare and may be restricted even if the darkness percentage is legal. |
Windshield Tint Rule in Maine
For Maine, the windshield rule should be checked separately from the side-window rule. Windshield tint is commonly limited to the upper strip, AS-1 area, or a specific medical authorization. Do not use the rear-window tint percentage as a windshield rule.
Key Maine Tint Compliance Notes
- A light transmittance certificate is required.
- Side windows behind the operator and the rear window are exempt from the 35% rule if the vehicle has two outside mirrors.
- Windshield tint is AS-1/top 5 inches, not top 4 inches.
Medical Window Tint Exemptions in Maine
Medical tint exemptions vary by state. Before installing darker tint for a health condition, confirm the required form, medical provider certification, vehicle documentation, expiration rules, and whether proof must be carried in the vehicle.
Tint Tickets, Inspections, and Penalties
Illegal tint may lead to a citation, failed inspection, required removal, or other penalties depending on state law and how the violation is handled locally. Verify fine amounts and court options with the official agency or court listed for your state.
What VLT Means Before You Buy Tint
VLT means visible light transmission. A lower VLT number means darker tint. For example, 20% VLT is darker than 35% VLT because less visible light passes through the window.
The legal reading usually depends on the glass and film together, not just the film box. That is why a film sold as 35% can test lower after it is installed on factory-tinted glass.
Before You Install Window Tint in Maine
- Check the legal VLT limit for each window, not just the front windows.
- Confirm whether your vehicle is a passenger car, SUV, van, pickup, or multipurpose vehicle.
- Ask the installer for the final measured VLT through the glass and film together.
- Verify whether labels, certificates, inspection rules, or medical authorization documents are required.
- Keep proof of any medical exemption or installer certificate in the vehicle if your state requires it.
