Diagram of a 450 mm by 450 mm (18 in by 18 in) county route marker, made to the specifications of the 2004 edition of Standard Highway Signs or the 2012 Supplement to the 2004 edition (sign M1-6). Uses the Roadgeek 2005 fonts. (United States law does not permit the copyrighting of typeface designs, and the fonts are meant to be copies of a U.S. Government-produced work anyway.) Colors are from the Federal Highway Administration's MUTCD Color Specifications (Pantone Blue 294 and Yellow 116). A gray, 1-pixel stroke was added to diagrams based on the 2012 specification to clearly show the border. In reality, signs have no such stroke.
