Possible dyslexia?

This sign talks about a possible fine if the rules are broken and proceeds to read "two-away zone." Two-away from what? I am wondering if I am two incidences away from a fine. So, who does this sign apply to? Are we all two incidences away?

I am assuming that the sign is supposed to read: "Penalty $100-500 Fine Tow-Away Zone." It seems that the "o" and "w" were mixed up which is an unfortunate occurrence. This sign is now very confusing and I don't think someone would want to stare at the sign very long in trying to figure out the message that is supposed to be put across. At first, I thought the mix up would be between "to," "too," and "two." Yet that does not even make sense. It is not good that these letters were mixed up because someone should definitely be aware if there car is in danger of being towed away.

The person that made this sign could have possibly been dyslexic. That would explain the mess up of the letters. However, I don't want to assume anything.
