For the safety of the public, traffic signs are placed in specific areas to prevent injuries to drivers, pedestrians, temporary construction workers, railroad workers, and emergency responders. Traffic signs communicate the rules on the road and are essential to regulate the flow of vehicles and protection of others. MUTCD (Manual on Uniform Traffic Control Devices) identifies that traffic signs and pavement markings on all roads open to the public, including private facilities that have public visitors, are to be printed on High-Intensity Prismatic. It is always best to ensure that traffic signs are retro reflective for the public's safety and improved visibility. Roll-Up Construction signs are perfect for a quick to set up, easy to take down and store solution. Select stock or custom traffic signs to keep pedestrians in and around public and private parking areas, dock areas, and roadways safe.
