30 in by 24 in (750 mm by 600 mm) Tennessee State Route shield, made to the specifications of the standard drawing. 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.) The outside border has a width of 1 (1/16 in) and a color of black so it shows up; in reality, signs have no outside border.

The symbol at the bottom is not perfect.
