If simple marking lines no longer meet the requirements under certain conditions, the GlasFIX, MarkFIX or AluFIX road markers are used. Because of the reflection they are also clearly visible at night or in the rain. In addition, the driver feels a slight vibration when driving over them and is thereby warned of the danger of a head-on collision or lane deviation. Pedestrian crossings, traffic islands, dangerous curves or complex traffic routeing are examples of applications.
