Louisiana-Specific Signs
Built to meet Louisiana requirements.
Louisiana Traffic Sign Requirements
Louisiana adopts the National MUTCD (Manual on Uniform Traffic Control Devices) together with a state supplement. Signs installed on Louisiana public roads must meet the national standard plus the state's specific modifications, enforced through the Louisiana 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 Louisiana 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 Louisiana road and work-zone requirements.
