Its a round-a-bout...but no one calls it that. It's either the circle or eight-corners. The first time my mom drove it she drove it backwards. There are a couple of unspoken rules. First, you never ever use your turn signal. Never. Second, when you see an opening go for it. Third, be sure to stop at the stop sign and be polite and don't go two in a row if others are waiting. OK, so that rule is never followed, but it would be the polite things to do. Fourth, never ever use your turn signal.
