Traffic Signs for Colorado
Equip Colorado roads, lots, and work zones with MUTCD-compliant traffic signs that ship fast.
Colorado Traffic Sign Requirements
Colorado adopts the National MUTCD (Manual on Uniform Traffic Control Devices) together with a state supplement, the Colorado Supplement to the MUTCD. Signs installed on Colorado public roads must meet the national standard plus the state's specific modifications, enforced through the Colorado 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 Colorado 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 Colorado road and work-zone requirements.
