| | AAA : International Road Signs (Site not responding. Last check: 2007-09-15) |
 | | In general, the color red on an international road sign signals negative information, such as a warning or prohibition, whereas blue is positive, signalling a required action or some feature (such as a bicycle lane, rest stop or parking garage) that you can take advantage of. |
 | | The signs on these pages tend to be warning and prohibitory signs (the red ones). |
 | | Most warning signs are enclosed with the red triangle, while the regulatory signs are a smattering of prohibitions, diamond-shaped priority signs and other guidance signs. |
