This bill amends the speed limit regulations for unpaved secondary roads under county jurisdiction in Iowa. It reduces the maximum speed limit from 55 miles per hour to 45 miles per hour for these roads, regardless of the time of day. The bill also updates the process by which county boards of supervisors can determine and declare reasonable speed limits based on engineering and traffic investigations, ensuring that appropriate signage is erected to inform drivers of any changes.

Additionally, the bill allows counties to use nonpermanent overlays or stickers approved by the department of transportation to update existing speed limit signs when implementing the new speed limits. This provision enables counties to display the new limits until they can replace the signs according to their replacement schedules and requirements. The bill maintains penalties for exceeding speed limits, which are classified as simple misdemeanors with fines that vary based on the degree of the infraction.
