National Marker Company signage instructs motorists to drive in a specific direction, indicating that a road is open for one way traffic only. It can be used in any road or carriage way to make sure that traffic safety is maintained. The legend ?ONE WAY? is printed in bold and legible text to make sure that the message is clearly visible even from a distance. The left arrow graphic is printed in black against a white base, making the message easy to understand. The square sign is UV resistant, chemical resistant and graffiti proof. The traffic safety signage has an NMC Sign Muscle coating to protect the graphic and text against fading, scratches, scuffing, mold, and moisture.
