Brighter signs. Safer roads.
  • Highway signs are highly reflective over a dark road at nighttime.
    Maximize reflected light

    3M’s full-cube retroreflective technology is more efficient and reflects more light than the conventional truncated cubes used in many Type IV and Type IX sheeting products. DG³ Reflective Sheeting uses 100% active-area retroreflectors that maximize reflected light, even on signs placed in less than optimal locations.

    Install the brightest full-cube sheeting

    When installed at the optimal angle, 3M™ Diamond Grade™ DG³ Reflective Sheeting outperforms the competition by delivering the highest luminance to the driver across important sign viewing scenarios:
     

    • 27% brighter for overhead signs and signs on the left shoulder
    • 30% brighter for signs on the right shoulder
  • Highly visible road signs indicate a curve in a mountain road.
    Road sign uniformity: what matters

    Help drivers get the information they need to interpret their surroundings and make critical decisions when they need it most. Fabricate signs with sheeting oriented to our recommended 0-degree or 90-degree angles to consistently deliver messages more quickly, effectively and safely.

    White Paper: Maximizing Brightness of Retroreflective Traffic Signs to Help Serve the Driving Population

    Brightness contributes to how a traffic sign is perceived by a driver, and the larger and brighter signs are, the more efficient they transfer the message. This means drivers need less time to understand it and go back to focusing on the road. In this white paper, we show how higher grades of retroreflective sign sheeting can help drivers understand signs sooner in dynamic driving conditions.
