General
Motorists must be warned when they are about to encounter a roadside hazard which they should keep either left or right of. To indicate to motorists which side(s) of the hazard they should maneuver their vehicle to, the WA-36 (L/R) hazard marker sign is used.
Standard
The Hazard Marker is used to mark obstructions adjacent to or within the roadway, such as bridge piers and traffic islands. The Hazard Marker may be used alone, or mounted below other signs.
Hazard marker signs consist of black diagonal stripes on a yellow background.
The WA-36 sign is used to mark an obstruction in the roadway which may be passed on either side.

Guidelines for Use
Where obstructions exist within or near the roadway and it is necessary to warn motorists of these obstacles so that they can safely maneuver their vehicle around the hazard, the applicable Hazard Marker sign should be installed.
Situations where Hazard Marker signs are typically used include, but are not limited to:
On both sides of the approach to a bridge in each direction of travel (i.e., at every corner of the bridge) Bridge piers Raised islands for right turn channelization at an intersection Type 6 log haul intersection jughandles
At divided highway transitions Hazard Markers should not be used on exit gores of provincial highways.
Guidelines for Placement
Where used, the placement and mounting height will vary depending on the sign application. The most common applications of the Hazard Marker sign, and the corresponding appropriate placement, are described here.
Application 1: Hazard Marker sign supplements another sign on the same post
In this situation, the Recommended Practices guideline entitled Placement of Signs would dictate the vertical placement of the main/top sign, and the Hazard Marker sign should be mounted directly below.
Application 2: Hazard Marker used alone
Under these circumstances, the horizontal placement of the Hazard Marker sign should be consistent with the Placement of Signs guideline. However, the sign should be installed at a height of 1.2 metres above the near edge of the nearest travel lane to the bottom of the sign, as is done with Chevron Alignment signs.
Application 3: Hazard Marker on Guardrail or Bridge Rail
Guardrail/bridge rail heights may vary, but all Hazard marker signs installed on these rails should be mounted with a separation distance of 380 mm between the top of the rail and the bottom of the sign.
