Regulatory sign

Traffic signs

Regulatory traffic signs follow international conventions, usually being:

• White circle or rectangle with red border, with a black pictogram, black text, or both
• Blue circle or rectangle with white border and white pictogram
• Red rectangle with white border and white text
• Red octagon with white border and white text (stop signs only)

United States

Regulatory traffic signs within the United States must comply with the federal Manual on Uniform Traffic Control Devices (MUTCD) or the State MUTCD, depending on the state in which the sign is installed. These signs typically have a white background with black or red legends (legends include text, symbols, graphics not part of the background); however, some specific signs may differ in their colors.
