Regulatory signs are generally rectangular with their longer dimension vertical, and carry a Black legend and border on a White background. The Stop sign is octagonal, and has a White legend on a Red background. The Yield sign is a White inverted triangle with Red legend and border band. The Do Not Enter sign consists of a White Square on which is inscribed a Red circle with a White band horizontally across the center of the circle and the words Do Not Enter in White letters on the upper and lower parts of the circle. The One Way sign may be either horizontal or vertical plate, the latter being used more commonly in the city where space is limited. Other commonly used regulatory signs are illustrated.
