Utah Window Tint Laws: What's Legal in 2026
Utah Window Tint Laws: What's Legal in 2026
If you drive in Eagle Mountain, Saratoga Springs, Lehi, or anywhere in Utah County, window tinting is one of the best upgrades you can make — but Utah has specific laws about how dark you can go. Getting it wrong means fines, failed inspections, and having to redo the job.
Important: Utah's tint law was updated in May 2025. The front side window limit changed from 43% to 35% VLT. Here's what you need to know to stay legal in 2026.
VLT: The Number That Matters
Utah regulates tint by VLT (Visible Light Transmission) — the percentage of visible light that passes through the film and glass combined. Lower VLT = darker tint.
Legal Limits in Utah (2026)
- Windshield: Non-reflective tint allowed on the top 4 inches (AS-1 line) only. No full windshield tint is legal.
- Front side windows: Must allow more than 35% of light in (VLT > 35%). This changed from 43% in the May 2025 amendment.
- Back side windows: Any darkness allowed.
- Rear window: Any darkness allowed.
Other Rules
- No metallic or mirrored tint: Any material with a metallic or mirrored appearance is strictly prohibited on any window.
- Side mirrors: Required if the rear window is tinted.
- Medical exemption: Utah allows darker tint with a medical exemption certificate for conditions like lupus or photosensitivity.
What This Means for You
If you want maximum privacy and heat rejection while staying legal, the smartest setup is:
- Front doors at 35% VLT (the legal limit)
- Back doors and rear as dark as you like (5% is common)
- A visor strip on the windshield (legal within the AS-1 line)
