Built to meet Iowa requirements.
Iowa Traffic Sign Requirements
Iowa adopts the National MUTCD (Manual on Uniform Traffic Control Devices) together with a state supplement. Signs installed on Iowa public roads must meet the national standard plus the state's specific modifications, enforced through the Iowa Department of Transportation.
MUTCD compliance
The MUTCD defines every standard regulatory (R), warning (W), and guide (G) sign — its exact size, legend, and colors. Our Iowa traffic signs are produced to those specifications so they are compliant out of the box, whether you need stop, yield, speed limit, or warning signs.
Reflectivity
Signs that face traffic must meet the FHWA minimum retroreflectivity levels in the MUTCD, and agencies are required to maintain them. We offer engineer-grade and high-intensity prismatic reflective sheeting to meet Iowa road and work-zone requirements.
