One of the first things you learn when you learn to drive is how to read and react to the traffic lights. This is something that we actually learn at a very young age, though how to work with them is something that takes on a whole new meaning once you are behind the wheel. My daughter for the longest time said that red meant stop, green means go, and yellow means Greg. She’s a fan of the Wiggles, so the yellow comment didn’t surprise me too much.
