been having this thought for the longest time...
but never really remember writing it down...
lol... old. LOLZ!!!
so on freeways, the sign boards are all blue...
and on highways the sign boards are all green.
while at residential areas, they are in white.
^^
has that ever occurred to you before?
and i guess that's one of the biggest problem why the signs keep misleading people here there...
my guess is, the companies and the government don't communicate when they do the signs...
and naturally the highway companies would like to lead you to their roads...
conspiracy... tsk tsk tsk...
