Chicago suburb started installing second
traffic signs below the normal ones. The new traffic signs are meant to grab drivers' attention by showing unusual traffic sign messages, like "Stop ... in the name of love" and "Stop ... right there pilgrim". Mayor Dave Heilmann said the "strange sign" campaign is mainly meant for "busy" people who are using iPods, blackberries, and cell phones while driving, and need to see something fresh and unusual to concentrate their attention.
