How dark can window tint be in Utah?
Darkness is measured as visible light transmission (VLT): the percentage of light that gets through. A lower number means darker tint.
| Window | Cars | SUVs and vans |
|---|---|---|
| Windshield | Non-reflective tint is allowed on the top 4 inches of the windshield or above the AS-1 line, whichever is lower. | |
| Front side windows | Must let in at least 35% of light (police allow a 5% variance). | |
| Back side windows | Any darkness is allowed. | Any darkness is allowed. |
| Rear window | Any darkness is allowed. | Any darkness is allowed. |
