Traffic sign visibility is critical at at all times, but especially during inclement weather or in low light situations. In order to appear bright to drivers eyes, signs need to have retroreflective surfaces so that the light striking them from vehicle headlights is reflected back to a driver’s eyes. Per the 2009 MUTCD all traffic signs, whether on public or private property, must be retroreflective. Hall Signs is committed to making you the highest quality products possible. Hall Signs stocks retroreflective materials from several manufacturers and is proud to offer the same materials to our customers for their sign making needs.
