There are signs everywhere. We may not be able to understand the language ,but we will probablyunderstand the signs there.
Different signs tell us different things. They give us:

•instructions (how to do something)  

•directions (where to go and how to get to a place)

•warnings (what we should not do) 

•information (what we need to know)
