The Keep Right sign indicates that traffic is required to pass to the right of obstructions such as medians, islands or underpass piers. The Object Marker (WA-36) may be used with the Keep Right sign.

On a median, the Keep Right sign should be mounted not more than 15m beyond the approach end. On a pedestrian island or intersection channelization island it should be mounted on the face of, or just in front of, a pier or other obstruction in the center of the road. In locations where stripe markings are also used on the obstruction, the stripe markings should be discontinued to leave a 10cm space around the outside of the Keep Right sign.

Where traffic is permitted to pass on either side of an island or other obstruction in the road, the Double Arrow sign (WA-17) must be used. The object marker
(WA-36) is normally placed below the Double Arrow sign.
