WOTC - Signs in buildings and roads

I asked this question in the Wisdom of the Crowd:

Do we have helpful signs in buildings and roads?

Here are the responses: (72 Votes)

38 % - Essential signs are often missing.
32 % - I have often been misled by inadequate or wrong signs.
15 % - Our signs are good.
15 % - There are too many advertisements that distract from the essential signs
