Retroreflectivity is crucial for helping drivers see road markings at night. Road markings are as important as road signs, providing key information for driving.

Today, reflective materials are used for road markings, including paints, cold-applied plastics, thermoplastics, self-adhesive tapes, modified epoxy resins, and raised pavement markers. Many of these use retroreflective glass beads to enhance nighttime visibility. Retroreflective markings bounce vehicle headlights back to the driver, making signs and markings more visible. 

In addition, some innovative solutions aim to improve traffic safety. For example, certain glass beads offer excellent retroreflectivity and resistance to traffic impact, performing well in colored road marking materials.
