What’s in it
AI summary Instead of letting the Department of Transportation set the rules for window tint, this law would set a specific minimum amount of light that must pass through vehicle windows. Drivers would be prohibited from using windows that are too dark or reflective, and they could face a $70 fine for breaking this rule. This change affects anyone driving on Iowa highways, though it does not apply to law enforcement officers on duty.1
Read the official explanation
Under current law, a person is prohibited from operating a motor vehicle equipped with a front windshield, a side window to the immediate right or left of the driver, or a sidewing forward of and to the left or right of the driver (window) which is excessively dark or reflective so that it is difficult for a person outside the motor vehicle to see into the motor vehicle through the window.7), “excessively dark or reflective” means the window does not meet a minimum standard of transparency of percent light transmittance. However, the requirement does not apply to a person who operates a motor vehicle owned or leased by a federal, state, or local law enforcement agency if the operation is part of the person’s official duties. _____ This bill strikes the authority of the DOT to adopt rules establishing a minimum measurable standard of transparency and instead prohibits a person from operating on the highway a motor vehicle equipped with a window that meets a minimum standard of transparency of less than percent light transmittance.438 is punishable by a scheduled fine of $70.
