Normative Signs: The Poetry of "Ought"

This one (from on Queens Quay in Toronto) is interesting for two reasons. One is the odd wording (infinitive, rather than a more standard imperative).

Perhaps more obviously weird is the use of the tragic word (and apparently it is a word), “signalized.” It’s certainly an awkward term, although this online dictionary says that signalized is indeed a word. I suspect very few people seeing this sign know the definition of the word, but I also suspect few fail to understand the sign’s meaning.

(Thanks to Andrew Crane for the picture, and for pointing out the unusual grammar.)
