This bill amends the speed limit regulations for unpaved roads under county jurisdiction in Iowa. It reduces the maximum speed limit from fifty-five miles per hour to forty-five miles per hour for secondary roads that are not surfaced with concrete or asphalt, regardless of the time of day. Additionally, it allows county boards of supervisors to determine and declare reasonable speed limits at specific intersections or parts of secondary roads based on engineering and traffic investigations.

Furthermore, the bill provides a mechanism for counties to update speed limit signage. It permits the use of nonpermanent overlays or stickers, approved by the department of transportation, to display the new speed limits on existing signs until they can be replaced according to the county's replacement schedule. The bill maintains penalties for exceeding speed limits, classifying such offenses as simple misdemeanors with fines that vary based on the degree of the speed violation.
