Legal Authority for Rule Making
This rule making is adopted under the authority provided in Iowa Code sections 307.12 and 321.423(7)"a" as amended by 2021 Iowa Acts, House File 654, section 5.
State or Federal Law Implemented

Purpose and Summary
This rule making adopts new Chapter 135 in accordance with 2021 Iowa Acts, House File 654, section 5. This new chapter allows non-State-owned vehicles and equipment to display flashing white lights within road work zones. The white lights are needed to help reduce the number of crashes involving construction vehicles and equipment on or adjacent to the roadway. The white lights will make non-State-owned vehicles and equipment more visible to other road workers and roadway users.
Public Comment and Changes to Rule Making
Notice of Intended Action for this rule making was published in the Iowa Administrative Bulletin on November 3, 2021, as ARC 6014C. No public comments were received. Two changes from the Notice have been made. The references to 2021 Iowa Acts, House File 654, section 5, have been removed from subrule 135.1(1) and the chapter implementation sentence because that legislation has been codified.
Adoption of Rule Making
This rule making was adopted by the Department on December 15, 2021.
Fiscal Impact
This rule making has no fiscal impact to the State of Iowa beyond any impact anticipated by the legislation.
Jobs Impact
After analysis and review of this rule making, there is a potential positive impact on jobs. Allowing non-State-owned vehicles and equipment to display flashing lights within road work zones will potentially increase the safety of road workers.
