Raised Pavement Marker RPM
Raised Pavement Marker RPM are technically known as retro-reflective raised pavement markers, they are a raised safety device glued onto roads to help define lines. They are small, moulded plastic squares with retro-reflective material inserted into them. The retro-reflective material within the device reflects light back to its source (this same material is also on road signs and safety vests). The move from white to yellow markers is designed to make the road’s centre line clearer in low-light conditions such as in rain, fog and at night. They will complement the white painted line marking which continues to provide the highest contrast with the road surface.
Raised Pavement Markers – Colour uses in NSW.
(a)White RRPMs are used to augment the lane lines.
(b) Yellow RRPMs are used to augment the dividing lines (separating opposing traffic), right hand edge lines of one-way carriageways, the outline of traffic islands and painted medians.
(c) Red RRPMs are used to augment the left hand edge lines.
(d) Blue RRPMs, although not an official delineation device, may be used on a road to mark fire hydrants or water supply locations. They shall not be used for any other purpose. The blue RRPMs are installed and maintained by the Fire Brigade or local council. They must be located 100 mm offset from the dividing line (or approximate centre where no dividing line is marked), on the side of the road where the hydrant is located.
When placed on freeways or motorways they should be placed on the shoulder to the left of edge line, opposite the fire hydrant. Because the location of fire hydrants may be difficult to see on high speed roads, the fire brigade may want to install supplemental signs.
