A bill for an act relating to motor vehicles equipped with an excessively dark or reflective front windshield, and making penalties applicable.

This bill (SSB 3132) sets a new enforcement standard for motor vehicle front windshields in Iowa, requiring a minimum of 50% light transmittance (down from the current 70% standard for visibility). Drivers operating vehicles with windshields below this 50% threshold face a citation and potential vehicle impoundment, though they may instead immediately fix the windshield to meet the 70% standard or tow the vehicle off the road. The bill prohibits operating an impounded vehicle until its windshield meets the 70% transmittance requirement, with a $70 fine for violations. It excludes law enforcement vehicles operated during official duties from these rules.
