Blue stop signs are not official traffic signs in the U.S. and are typically used in private areas like estates or golf courses.
While they indicate a stop, they are not authorized by state or federal authorities.
In places like Hawaii, blue stop signs are used on private land to signal drivers to stop without violating laws. In countries like Japan and Mexico, blue stop signs usually indicate restricted access or no-entry zones.
These signs are not used on public roads in the U.S. and are not enforceable. However, on private property, they may be placed to direct traffic safely. Always stop and check the area before proceeding.
