Í mismunandi löndum mun hafa mismunandi reglur kröfur fyrir vegmerki.
En allt Andlit umferðarmerkja verður að vera endurskinsmerki nema litað svart. Til þess að umferðarmerki uppfylli kröfur verða þau að uppfylla réttan staðal um endurspeglun og reglur um lit fyrir notkunina.
There is plenty of choice in regard to traffic signs; size, shape, material, reflectivity and more can vary. All these aspects play an important role in keeping road users safe, whether that's through directing traffic, warning of hazards, or protecting workers at street works. The reflectivity, in particular, ensures road users see important information during dark hours and plays a critical role in both compliance and lifesaving.
Hvað er endurskinsplata fyrir umferðarmerki?
Umferðarmerki eru að jafnaði gerð úr a Aluminium, which is then covered with reflective sheeting. Reflective sheeting is the material that makes road signs visible in the dark without having to rely on electricity.

Endurskinsandi glerperlur
Glerperlubönd nota smásæjar glerkúlur til að beygja og endurkasta ljósi aftur til ljósgjafans. Vegna ófullkomleika og bogadregna yfirborðs í glerperlum,lakmade with beads are less reflective than tapes made with prisms. Glass bead lak are about 30 percent efficient. This is a disadvantage. However, there are three advantages that glass bead lak has over most prismatic lak. First, glass bead reflective lak are much more affordable. This is because they are simpler to manufacture. Second, most glass bead sheeting are CAD cuttable meaning that you can cut letters, number and designs out of the tape and create reflective signs or graphics. Third, glass bead lakreflect light back at wider angles. In other words, glass bead lak are sort of like flood lamps whereas prismatic sheeting are more light spot lights.

Ör prismatísk lak
Prismatic is more efficient and returns about 80 percent of the light sent to it. Therefore it is brighter than glass bead tapes. Prismatic tape reflects light via man made prisms. Since the mirrors are flat and not curved they are more efficient. The light sent from the tape is more focused and can therefore travel farther still be seen.
