Iowa Car Window Tinting Laws

Window tinting has become a popular trend among car owners in Iowa. However, it is important to know the laws and regulations surrounding window tinting to avoid fines and legal complications.

In this article, we will cover the different Iowa car window tinting laws and regulations to help you make an informed decision.

Tint Darkness for Sedans

The law requires that sedans have a minimum of 70% visible light transmission (VLT) on their windshield. This means that only 30% of the light must pass through the tint.

The front side windows must have a minimum of 70% VLT as well. Tinting the back side windows and rear window is allowed as long as it does not block more than 35% of the light.

Tint Darkness for SUV and Vans

The law requires that SUV and vans have the same regulations for windshield and front side window tint as sedans. However, the back side windows and rear window can have a darker tint, but must still let at least 35% of the light pass through.

Tint Reflection in Iowa

The front side windows and back side windows must not have more than 35% total reflectance. This means that the tint must not be too reflective and can only reflect up to 35% of the light.

This is to prevent glare and obstruction of the driver’s sight.

Other Iowa Window Tinting Rules and Regulations

In addition to the minimum VLT and reflectance requirements, there are other regulations that must be followed. All vehicles with tinted windows must have side mirrors that provide an adequate view behind the vehicle.

The tint used must not be of a red, blue, or amber color, or any other color that is not transparent. A certificate of compliance must be obtained from the installer and displayed on the vehicle’s windshield.

Stickers must also be placed on the vehicle’s windshield, front side windows, and back side windows, indicating that the tint is legal. There are medical exemptions for individuals with certain medical conditions that require special window tinting.
