What’s in it

AI summary Drivers would no longer follow Department of Transportation rules for window tint, but instead must follow specific laws about how much light can pass through their windows. Front windshields must allow at least 70 percent of light through, while side windows next to the driver must allow at least 50 percent. Other side or rear windows must allow at least 35 percent of light through. These rules do not apply to law enforcement officers performing their official duties.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 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.5), “excessively dark or reflective” means the window does not meet a minimum standard of transparency of 70 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 front windshield that meets a minimum standard of transparency of less than 70 percent light transmittance, a side window or sidewing immediately beside or forward of the driver, as applicable, that meets a minimum standard of transparency of less than 50 percent light transmittance, and a side or rear window other than a side window or sidewing immediately beside or forward of the driver to meet a minimum standard of transparency of at least 35 percent light transmittance. Under current law, the light transmittance of such other windows is not regulated.438 is punishable by a scheduled fine of $70.
