Yes. All the object markers, delineators, and post panels are retroreflective. Our products come with 3M reflective sheeting that meets or exceeds MUTCD specifications for reflectivity. Retroreflectivity is one of the many factors associated with maintaining nighttime visibility. Our signage offers excellent visibility in the day and reflects brilliantly at night when lights from headlights or flashlights strike on the surface. 3M Hi-Intensity Prismatic signs meet most federal and state guidelines on reflectivity. We also have Diamond Grade reflective signs which is the brightest sign material produced by 3M. These signs offer three times the reflectivity of Hi-Intensity and ten times the reflectivity of Engineer Grade reflective signs.
