Signs, Signals, & Barricades

Signs and symbols will be visible at all times when work is being performed and will be removed or covered promptly when the hazards no longer exist.

• Danger signs (see Figure G-1) will be used only where an immediate hazard exists and will have red as the predominating color for the upper panel; black outline on the borders; and a white lower panel for additional sign wording.

• Caution signs (see Figure G-2) will be used only to warn against potential hazards or to caution against unsafe practices and will have yellow as the predominating color; black upper panel and borders: yellow lettering of “caution” on the black panel; and the lower yellow panel for additional sign wording. Black lettering will be used for additional wording.

Construction areas shall be posted with legible traffic signs at points of hazard and all traffic control signs or devices used for protection of construction workers will conform to Part VI of the Manual of Uniform Traffic Control Devices (AMUTCD”), 1988 Edition, Revision 3, September 3, 1993, FHWA-SA-94-027 or Part VI of the Manual on Uniform Traffic Control Devices, Millennium Edition, December 2000, FHWA.
