Providing for an exception to motor vehicle window tint limitations for persons with certain medical conditions

Current law prohibits a person from operating on the highway a motor vehicle that is equipped with a front windshield, a side window, or a sidewing which is excessively dark or reflective such that it is difficult for a person outside the motor vehicle to see into the motor vehicle through the windshield, window, or sidewing. By administrative rule, the department of transportation (DOT) defines “excessively dark or reflective” to mean that the windshield, side window, or sidewing does not meet a minimum standard of transparency of percent light transmittance. This bill provides an exception to the prohibition on excessively dark or reflective motor vehicle window tint where the person operating the motor vehicle has an affidavit signed by a physician, advanced registered nurse practitioner, physician assistant, or optometrist licensed under Iowa law stating that such person has a medical condition involving extreme sensitivity to light that makes it necessary for a motor vehicle operated by the person to be equipped with necessary window tint that would otherwise be prohibited. The DOT will be responsible for prescribing a form affidavit pursuant to the requirements of the bill. A copy of the affidavit must be carried in the motor vehicle at all times.
