Purpose

The sign identification decal is used to record sufficient information about the reflective sheeting to determine its origin in case of premature failure of the material. The Traffic Materials Branch of the Construction Division (CST) should be notified of suspected failures. Information reported to the Traffic Materials Branch (CST) should include the location and orientation of the sign.
The decal identifies:
  • the manufacturer of the background reflective sheeting
  • the manufacturer of the legend and border sheeting
  • the place and time (year and month) of sign fabrication, and
  • the date on which the sign was installed in the field.
Identifying the date of installation facilitates analysis of the durability of different manufacturers' sign materials under varying field conditions and assists in determining the need for replacement.
