Bill > HF766

This bill, effective July 1, 2026, amends Iowa law regarding motor vehicle window tint by establishing specific minimum standards for light transmittance. It prohibits operating a vehicle with a front windshield that allows less than seventy percent of light to pass through, and side windows or forward side windows (sidewings) that allow less than fifty percent of light to pass through. The bill removes the previous, more general prohibition against windows being "excessively dark or reflective" and the department's responsibility to set a minimum standard, instead codifying these specific percentages directly into law. An exception is made for vehicles owned or leased by federal, state, or local law enforcement agencies when used for official duties.
