In the U.S. state of Iowa, the Iowa Code defines secondary roads as those roads under county jurisdiction, that is, any roads which are owned and maintained by the county in which they reside. Secondary roads represent 79% of the state's public road system, which amounts to over 89,000 highway miles (143,000 km). Secondary roads are divided into two classes: farm-to-market roads and area service roads. Farm-to-market roads are county roads which serve communities and provide short connections to other farm-to-market roads. The farm-to-market road system is limited by law to 35,000 miles (56,000 km) by law. Area service roads are simply defined as county roads which are not part of the farm-to-market road system.

Legal definition
Secondary roads are defined simply as those roads under county jurisdiction.[1] The Board of Supervisors in each county is responsible for maintaining the secondary roads in their respective county. In cities where the population is below 500 residents, the county is responsible for maintaining farm-to-market roads which pass through the city.[2]
Road classifications
Secondary roads are divided into two classes: farm-to-market roads and area service roads. Most farm-to-market roads are paved, two-lane highways. Most are signed with the MUTCD-standard, blue pentagon for county roads. However, not all farm-to-market roads are paved, and not all signed routes are farm-to-market roads.
