How dark can window tint be in Minnesota?
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 | No tint is allowed on the windshield. | |
| Front side windows | Must let in more than 50% of light. | |
| Back side windows | Must let in more than 50% of light. | Any darkness is allowed. |
| Rear window | Must let in more than 50% of light. | Any darkness is allowed. |

The Minnesota Window Film Association campaigned for a more lenient law, saying the 50% net limit pushed tint shops underground or out of state. The 50% limit on side and rear windows still stands.
