Road Signs in the Second American Empire
Road signs in the Second American Empire standards were adopted from various road standards such as MUTCD, German standards, and Vienna Convention on Road Signs and Signals standards. Although a number of changes over the years have introduced some slight deviations that suit local road conditions (such as fonts). Road signs in America conform to the local Traffic and Driving code under the authority of the American Road Authority.
American signs depict classical silhouetted persons.
Warning signs warn of possible dangers or unusual conditions ahead and alert motorists on the hazards to expect. They are similar to the United States design, in that they are black on an amber (orangish-yellow) background, and are diamond-shaped.
There is also some of the American standards uses the European triangles with a red border signs.
Regulatory signs either give positive instructions, i.e. Mandatory signs, or indicate a prohibition, i.e. Prohibitionary signs. Many regulatory signs are accompanied by supplementary plates that provide interdependent exceptions to the rule or indicates additional instruction or information to facilitate understanding of the rule implemented.
Mandatory signs are generally circular with a white border and symbol on a blue background. They usually indicate something all drivers must do (e.g. keep left) or a facility available to certain classes of traffic (e.g. pedal cycles only).
The exceptions are the octagonal red STOP sign, the triangular GIVE WAY sign and the various mandatory STOP signs that are circular and have a red border.
Prohibitory signs, which generally tell drivers what they must not do, are mostly circular and have a red border. The red ring indicates the prohibition; diagonal bars are used only on signs which prohibit a specific maneuver, i.e. banned left or right turns and U-turns, or a certain class of vehicle, i.e. lorries.
