Window Tint laws in Iowa

Iowa Code Section 321.438 sets the regulations for window tinting. For windows to the immediate right and left of the driver, the light transmittance must not be less than 70%. This means that 70% of visible light must pass through the window. For all other windows, including rear windows and side windows not immediately adjacent to the driver, the light transmittance must not be less than 35%. This provision ensures that a certain level of visibility is maintained for safety. Exemptions may exist for certain medical conditions, which would require a doctor's certification. The use of reflective materials on windows is also generally restricted if it reduces light transmittance below the legal limits. Windshield tint is typically only allowed on the top six inches of the windshield, not extending below the AS-1 line, if present. There are also specific rules about the color of tint, generally prohibiting red, amber, or yellow tint. The law aims to balance vehicle customization with public safety, ensuring that drivers maintain adequate visibility and that law enforcement officers can see into vehicles. Violations of tint laws can lead to citations and fines, and the vehicle owner may be required to remove the illegal tint. Law enforcement officers may use a tint meter to measure the light transmittance of vehicle windows during a traffic stop. It is the responsibility of the vehicle owner to ensure their tint complies with Iowa law. These regulations apply to all vehicles operated on Iowa roadways, regardless of where they were originally registered.
