600 mm by 300 mm (24 in by 12 in) north plate, made to the specifications of the <a rel="nofollow" class="external text" href="http://mutcd.fhwa.dot.gov/SHSm/Guide.pdf">2004 edition of Standard Highway Signs</a> (sign M3-1). Uses the <a rel="nofollow" class="external text" href="http://www.triskele.com/fonts/index.html">Roadgeek 2005 fonts</a>. (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.) The outside border has a width of 1 (1 mm) and a color of black so it shows up; in reality, signs have no outside border.
