As you’re driving through Iowa, you coincidentally pass by a car with tinted windows that seem darker than usual. You can’t help but wonder if they’re legal. It’s a good thing you’re curious, because Iowa has specific window tinting laws that drivers must follow to guarantee safe driving conditions.

For instance, did you know that windshields can only have a tint that allows at least 70% of light transmission? But that’s just the tip of the iceberg – there are more regulations to investigate, and understanding them can save you from a hefty fine.

Iowa Window Tinting Laws

Window Tint Darkness in Iowa

Across the Hawkeye State, motorists must adhere to specific window tint darkness regulations to avoid fines and penalties.

You should be aware that Iowa law permits a certain level of window tint darkness on your vehicle’s windows. The allowed tint is measured by the percentage of light transmission, which is the amount of visible light that can pass through the window.

For your windshield, the tint is allowed up to 70% light transmission, meaning at least 70% of the light must pass through. For your front side windows, the tint must allow at least 68% light transmission.

Rear and back side windows have no specific restrictions on window tint darkness.
