MUTCD Signs Reflectivity Requirements

What is MUTCD?

The Manual on Uniform Traffic Control Devices (MUTCD) is a document issued by the Federal Highway Administration (FHWA) of the United States Department of Transportation (USDOT) to specify the standards by which traffic signs, road surface markings, and signals are designed, installed, and used. These specifications include the shapes, colors, and fonts used in road markings and signs. In the United States, all traffic control devices must generally conform to these standards.

For more information, visit the official MUTCD website or the DOT website.

What happens if I don't comply?
