TRANSPORTATION DEPARTMENT[761]

Notice of Intended Action

Proposing rulemaking related to special permits for operation and movement of vehicles and loads of excess size and weight and providing an opportunity for public comment

    The Transportation Department hereby proposes to amend Chapter 511, “Special Permits for Operation and Movement of Vehicles and Loads of Excess Size and Weight,” Iowa Administrative Code.

Legal Authority for Rulemaking

    This rulemaking is proposed under the authority provided in Iowa Code sections 321E.3 and 321E.15.

State or Federal Law Implemented

    This rulemaking implements, in whole or in part, Iowa Code sections 321E.3 and 321E.12.

Purpose and Summary

    The purpose of the proposed amendments to the chapter is to comply with 2025 Iowa Acts, House File 979, sections 1 and 4.

    House File 979 amended Iowa Code section 321E.3. Changes to Iowa Code section 321E.3 include an alteration in the routes for which the Department may issue all-systems permits under Iowa Code section 321E.8, a requirement for secondary roads and designated truck routes to be valid unless the local authority communicates the nonvalid designation to the Department in writing, and a requirement for a local authority to work with the Department to find an alternate route for a permitted vehicle if all roads to the loading or unloading destination are not valid. Iowa Code section 321E.3 also now states that all nonvalid designations are subject to Department review and requires the Department to adopt rules to resolve exemption determination disputes and establish a process for alternate route requests.

    House File 979 also amended Iowa Code section 321E.12 to allow a vehicle traveling under a single-trip permit to meet the statutory requirement to be registered for the gross weight of the vehicle and load by collecting the required tonnage fees along with the permit application.

The department will accept the submittal of exemption justifications in the form and manner prescribed by the department, including via communications between electronic systems.

The department, after consultation with county and city officials through their representative organizations, establishes a procedure for alternate route requests. The alternate route procedure is as follows:

    a.   The permit holder will contact the local authority to request an alternate route. Contact information for each local public agency is obtained by clicking on the desired route in the all-systems overweight permit map found on the department’s website for motor carriers.

    (1)   If, upon further evaluation, the local authority chooses to designate the requested route as valid, the local authority must contact the department to remove the non-valid designation. The local authority will notify the permit holder of the removal of the non-valid designation.

    (2)   If the local authority establishes an alternate route, the local authority must provide written notice to the permit holder of the approved alternate route and the dates for which the route is valid. The written notice is given in the form and manner prescribed by the department or in an alternate form and manner approved by the department.

    b.   If the local authority does not respond to the request to establish an alternate route after five business days, or if the local authority does not make the existing route valid, provide an acceptable alternate route, or resolve the situation within seven business days, the permit holder may contact the department to request the department establish an alternate route.

    (1)   In establishing the alternate route, the department will consult with the local authority, if responsive, and may consult with stakeholders, including but not limited to the permit holder, and county and city officials through their representative organizations.

    (2)   Once the department has established an alternate route, the department will provide written notice to the permit holder and the local authority of the established alternate route and the dates for which the alternate route is valid.

Additional guidance is published on the department’s website.

This rule is intended to implement Iowa Code sections 312.2, 321.454, 321.456, 321.457, 321.463, 321E.2, 321E.3, 321E.8, 321E.10 and 321E.15.
