Demountable copy is a form of traffic sign in which mass-produced sheet-metal characters (and graphics, such as route shields and arrows) are attached to the sign face through means such as screws, rivets and adhesives.{{cite web |title=Retroreflective Sign Sheetings |url=http://www.trafficsign.us/signsheet.html |website=Manual of Traffic Signs |access-date=January 17, 2021}}

Because of the ability to remove the preformed metal characters from the sign, demountable-copy signs can be easily altered to change their message by removing unwanted sections of the legend and installing new elements.

Some states formerly applied their demountable characters to non-retroreflective sheeting but phased out the process when the glue used began to leak and damage the signs.{{cite web |title=Signing in California/Signing Standards |url=https://www.cahighways.org/num-signing.html |website=California Highways |access-date=January 17, 2021}}
