The National Committee on Uniform Traffic Control Devices (NCUTCD) is a private nonprofit corporation chartered in the state of Arizona, with over 300 technical and voting members from across the United States.

The purpose of NCUTCD, as stated on its website, is to assist in the development of standards, guides and warrants for traffic control devices and practices used to regulate, warn and guide traffic on streets and highways.

NCUTCD recommends to the Federal Highway Administration (FHWA) and to other appropriate agencies proposed revisions and interpretations to the Manual on Uniform Traffic Control Devices (MUTCD) and other accepted national standards.

NCUTCD develops public and professional awareness of the principles of safe traffic control devices and practices and provides a forum for qualified individuals with diverse backgrounds and viewpoints to exchange professional information.
