Iowa Code Title VIII. Transportation [Chs. 306-330B] § 321E.3. Permit-issuing authorities

b. (1) The department may issue all-systems permits under section 321E.8 which are valid for movement on all paved highways or streets, except the interstate road system if prohibited under section 321E.8, and except any highways or streets under the jurisdiction of local authorities upon which an all-systems permit is not valid as determined by the applicable local authority if the local authority indicates such highways and streets to the department in writing, including by means of electronic communication. However, a local authority shall not determine that any paved farm-to-market road, or highway or street designated as a truck route, is not valid for purposes of an all-systems permit without justification. A highway or street under the jurisdiction of a local authority upon which movement under an all-systems permit is valid shall connect with a highway or street under the jurisdiction of the state, or with another highway or street upon which movement under an all-systems permit is valid that ultimately connects with a highway or street under the jurisdiction of the state.

(2) A local authority that indicates a highway or street, including a paved farm-to-market road, upon which an all-systems permit is not valid under subparagraph (1) shall provide a written justification report to the department explaining the local authority's determination. If the department disagrees with the local authority's determination, the dispute shall be resolved in accordance with chapter 17A.

(3) Notwithstanding a local authority's determination under this paragraph, a person who is issued an all-systems permit may operate a permitted vehicle over the most direct route between the location where the vehicle is loaded or is to be unloaded and the nearest highway or street upon which movement under an all-systems permit is valid.
