The Qualified Products List (QPL) contains traffic signal equipment and material standards that are approved for use on contract projects on the North Carolina State Highway System. Although this list is generally valid for NCDOT projects, the project specific Project Special Provisions may be more restrictive than this list. Please see the Product Standards and Requirements page for more information.

NOTE: Please use the 2002 QPL to create submittals for  ALL Projects advertised before the July 2006 letting. Use the 2006 QPL for all Projects stating the 2006 Standard Specifications for Roads and Structures as the governing specification over Traffic Signal equipment and installation.
