Mini-roundabouts. Approach these in the same way as normal roundabouts. All vehicles MUST pass round the central markings except large vehicles which are physically incapable of doing so. Remember, there is less space to manoeuvre and less time to signal. Avoid making U-turns at mini-roundabouts. Beware of others doing this.
A mini-roundabout is normally found on a road with a speed limit of 30mph of less. It should be treated the same as a conventional roundabout. You must give way to traffic from the right, and keep to the left of the white circle unless the size of your vehicle or the junction layout makes driving over it unavoidable
