The stripes occur in almost any road environment, urban or suburban, and play a key role in the functionality and safety of traffic. Lines marking the edges of the road and separating the traffic lanes provide significant assistance to the driver in the task of checking the position on the road, both in relation to the ends of the road and lanes, as well as to other cars. that are around him. The benefits of stripping for visual guidance become especially important when the weather is poor, or at night, when the eye cannot discern the elements surrounding the road. Also, if the driver is dazzled by the headlights coming from the opposite direction, he can control his position based on the roadside marking, thus avoiding looking in front.
The color of the stripes can be white, yellow or cyan, while red is used externally. In Greece the color applied to the majority of the stripes is white. Yellow and cyan are mainly applied to stripes related to parking control. Yellow are also markings in areas with frequent fogs, as well as temporary markings in project areas, which override existing whites.
