US Road Signs: Traffic Signs and Meaning

The comprehensive listing of the most commonly used road signs in the United States

Roadway signs in the United States come in different colors: red is only used on stop, yield and prohibition signs. Regulatory signs always have white background, and yellow is used to convey a general warning message. Green signs refer to permitted traffic direction or movement, and fluorescent yellow or green is reserved for pedestrian crossings and school zones. Coral can be found on incident management signs, brown guides you to public recreation or cultural interest sites, orange road signs are used for warning and guidance in roadway work zones, and blue signs guide you to road user services, tourist info or evacuation routes. Standards for the design and application of the signs shown here are outlined in the Manual on Uniform Traffic Control Devices (MUTCD).
