Diagram of a mini-roundabout showing sign placement. An optional diamond-shaped sign showing three curved black arrows curving to the left in a circular pattern to indicate a roundabout ahead may be placed on the approach to the roundabout, as may the cross-street name. Optional pedestrian crossing signs may also be placed in both directions in advance of the pedestrian crosswalk that crosses the splitter island. A triangular red yield sign must be located at the yield line on the approach to the mini-roundabout, and a roundabout ahead sign must be placed below the yield sign.
