4.2 Number of Legs

Single-lane roundabouts can operate satisfactorily with more than four legs. However, the provision of more than four legs or legs at angles other than approximately 90° should be avoided for multi-lane roundabouts as this can create conflict at exits. Drivers can also experience difficulty in identifying the appropriate lane choice required for left, through and right turns on some approaches – Section 4.5.2 and Commentary 20, Guide to Traffic Management Part 6: Intersections, Interchanges and Crossings (Austroads 2013a).
