The MassDOT Highway Division is responsible for furnishing adequate directional and informational signing on the State Highway system. The general guidance for this responsibility is found in Chapter 85, Sections 2 and 2D of the General Laws of Massachusetts, in the nationally applied Manual on Uniform Traffic Control Devices (MUTCD), and in the Massachusetts Amendments to the MUTCD. All types of supplemental signing shall conform to the requirements of the MUTCD, in addition to any restrictions outlined within the Supplemental Sign Policy. The purpose of MassDOT's Supplemental Sign Policy is to provide signs along state highways that best serve the interest of those served by the highway system, subject to safety and consistency standards.
Information and application packages for various types of supplemental signs may be found in the links below. Applications may be filled out electronically but must be submitted as a signed hard copy. Applications should be submitted to the MassDOT District Office having jurisdiction over the location of the proposed sign.
The Supplemental Sign Policy was last revised in December 13, 2010.
