Retroreflective highway signs and lane markers use special kinds of paints and materials to keep traffic safety. Most retroreflective paints and other road marking materials contain many thousands of glass beads per square foot that are bonded to the road surface with a strong blinder. Instead of scattering light, retroreflective paints containing glass beads turn the light around and send it back to the direction of the driver’s headlights.This is called retroreflection. The driver can see that the light appears to be coming from the striping.
