Road Signs Gone Wrong

I've been thinking about mistakes that are made in English and how they are tiresome to hear after having been corrected so many times. I was also thinking about signs that go up without being so much as glanced over for mistakes. Who puts up a sign without proofreading it first? Especially if this sign has just one word and will be read by many, many, many people!

These are mistakes that could've easily been avoided, I mean really!
