This is a retouched picture, which means that it has been digitally altered from its original version. Modifications: Combined Two files to make a new highway number. The original can be viewed here: NC 168.svg: . Modifications made by Juanricos.

This file is in the public domain because it comes from the North Carolina Supplement to the Manual on Uniform Traffic Control Devices, sign number M1-5, which states on p. I-2 that North Carolina has "adopted and incorporated" the federal Manual on Uniform Traffic Control Devices in its totality except for the "standards for all traffic control devices applicable to North Carolina not contained in the MUTCD". The federal MUTCD states specifically on its page I-1 that: Any traffic control device design or application provision contained in this Manual shall be considered to be in the public domain. Traffic control devices contained in this Manual shall not be protected by a patent, trademark, or copyright, except for the Interstate Shield and any other items owned by FHWA. No provisions of the supplement supersede this provision of the MUTCD.
