While on our whirlwind trip to Indianapolis and back this weekend, my middle son told me something new he had learned just recently. Did you know that the exit number located at the of expressway signs are supposed to be positioned on the side of the sign where the exit is located? In other words, if the exit number is on the top right of the sign, the exit will be to the right and if it is located at the top left of the sign, then the exit will be to the left.

I had no idea! I have been studying maps since I was a kid and driving for nearly many years and never realized this little tidbit of information. Just goes to show you that you never stop learning. I would be curious to learn if this is also true along highways, byways, freeways, tollways, autobahns, autoroutes, autopistas, and other expressways outside the United States.
