A bill for an act relating to the issuance and display of one registration plate on motor vehicles.

Iowa Senate Study Bill 1091 (SSB1091) was introduced in February 2025 to change the state's vehicle registration system by requiring only one license plate to be issued and displayed on motor vehicles, instead of the current two-plate system. This means vehicles would display a single plate, likely on the rear, rather than both front and rear plates.

Supporters of SSB1091 argue that moving to a single license plate system could reduce costs for both the state and vehicle owners. They also suggest that it would enhance the aesthetic appeal of vehicles, particularly for classic and luxury cars, and align Iowa with neighboring states that have already adopted a single-plate system.

Opponents of the bill express concerns that eliminating front license plates could hinder law enforcement efforts, as front plates are useful for identifying vehicles involved in crimes or traffic violations. Additionally, they worry that the change could negatively impact toll collection systems and automated traffic enforcement cameras that rely on front plates for vehicle identification.
