In right hand traffic countries, revolving doors typically revolve counter-clockwise (as seen from above), allowing people to enter and exit only on the right side of the door. In left hand traffic countries such as Australia and New Zealand,[4] revolving doors revolve clockwise,[5] but door rotations are mixed in Britain.[6] Direction of rotation is often enforced by the door governor mechanism, or by the orientation of the door seal brush (weatherstrips).
