While driving to work the other day, I was careful to observe the speed limit- as several other girls in my dorm had gotten tickets the past week. The speed limit was 45. Not so bad. But then, while driving home from work-on the same road-I noticed the speed limit was 30. The signs were even at the same place; I glanced in my mirror to see if I was remembering the other one correctly. And sure enough, it was 45. My question: Why? It’s the same road-just two different directions. Why are there two different speed limits? Is this legal? Could I get a ticket for going 45 in both directions? I’ve never seen this before, and it makes no sense to me whatsoever.
