The dance floor is divided into concentric lanes like the picture above. The outside lane is the FAST lane.
Traffic moves around the dance floor in a counter-clockwise direction.
If you are going slow, stay in an inner lane and let people pass you on the outside. The closer you go to the center, the slower you may go. If you are doing a stationary dances such as a line dance or swing dance instead of a progressive dance, you should dance in the center area of the floor. Line dancers should never line up clear out to the rail and block progressive dancers. This gives line dancing a bad reputation.
