3M Reflectivity Levels
During daylight hours there is barely any discernable difference between the various types of 3M Reflective materials above. However the image above shows the vast difference between the engineer grade on the left, the high intensity prismatic in the middle and the diamond grade prismatic on the right. The difference is dramatic. The most common choice for public roads and dangerous intersections is clear. 3M Diamond Grade is the winner here.

• Hidden junctions and intersections
• Poor or concealed warning signs
