Sign Design of North America and Australia

In North America and Australia traffic signs usually follow strict colors and combinations. They are as follows:

1. Informational signs, these give directions, distance, and indicate places such as town, city, and state names. These signs are green with white lettering.
2. Signs used by parks, historic sites, ski areas, forestry, and campgrounds are brown with white lettering.
3. Informational signs that are used for rest areas, food, gasoline, petrol, and lodging are blue with white lettering.
4. Regulatory signs such as speed limits and parking signs are white with red or black lettering. In some cases, they are red or black signs with white lettering.
5. Warning or caution signs used to warn of school zones, ice on roads or bridges, or dangerous curves are yellow with black lettering.
6. Temporary traffic control zones and detour signs are orange with black lettering.

Several U.S. states currently use fluorescent orange signs for construction zones, making them easier to be seen at night and during inclement weather. They have also converted to fluorescent yellow-green (FYG) in school zones, crosswalks, as well as for pedestrian, and bicycle warning signs and fluorescent pink is sometimes used for incident management warning signs.
