We don’t just wave our hands around and make vague suggestions in Albuquerque. We communicate with absolute accuracy! Or maybe the sign manufacturer ran out of the digits “0” and “5”, forcing them to get creative. But then again, this could be the result of a late-night political argument within the city council, resulting in a two-in-the-morning compromise so everyone could go home! Hmmmm. My best guess? This was one of the city’s early attempts to provide “synchronized traffic lights”. 🙂 I dunno. Your guess is as good as mine.
