What’s in it

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.7), “excessively dark or reflective” means the window does not meet a minimum standard of transparency of percent light transmittance.

Read the full explanation

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 percent light transmittance or a side window or sidewing immediately beside or forward of the driver, as applicable, that meets a minimum standard of transparency of less than percent light transmittance.438 is punishable by a scheduled fine of $70.
