No, 50% window tint is not universally legal in Maine. State law mandates front-side windows allow at least 70% light transmittance, while rear windows may vary by vehicle type. Local enforcement by the Maine Bureau of Motor Vehicles (BMV) and municipal police scrutinizes non-compliant tints, with 2026 compliance checks expected to tighten.
Key Regulations for 50% Window Tint in Maine
- Front-side windows: Must permit ≥70% light transmittance; 50% tint violates this threshold.
- Rear windows: Permitted for sedans if vehicle has side mirrors, but commercial vehicles face stricter limits.
- Medical exemptions: Require BMV-approved documentation; standard 50% tint remains prohibited without waiver.
The Maine Revised Statutes Title 29-A, §1913 governs window tinting, with enforcement delegated to the BMV and local law enforcement. Non-compliance risks fines up to $100 per violation, and 2026 BMV audits will prioritize rear-window compliance for commercial fleets. Vehicles registered out-of-state must adhere to Maine’s standards upon transfer of registration. Medical exemptions undergo annual renewal, and aftermarket tints failing to meet luminous transmittance standards are subject to removal orders.
