Table of Content


1.1 General

The removal or covering of stock crossing signs when not in use is mandatory. Signs that are displayed while not in use may bring all signing into disrepute and may result in motorists disregarding important warnings. Signs should be covered such that they are not visible in all light conditions. More Information.

1.2 Stock Crossing

1.2.1 Stock Crossings with Sight Distance Greater than 300 Metres

Where a stock crossing is located such that approaching motorists can see the stock crossing point from more than 300m away, signing should be as per Figure 1.


FIGURE 1 - Typical Stock Crossing Site


The crossing should desirably not be used when sun glare will interfere with drivers' view of the traffic signs or stock on the road.

Where stock movements are adjacent to or encompass an intersection, STOCK AHEAD and ON SIDE ROAD signs should be used on the side roads, to alert motorists entering the road that there is stock on the road. The location of the STOCK AHEAD sign should be based on a distance from the stock crossing as shown in Table 2.

1.2.3 Use of Stock Crossings Dering Night-Time, Periods of Poor Visibility or Hazardous Locations

Daylight use of stock crossings is preferred. Where the stock crossing is proposed to be used during nighttime, periods of poor visibility or in a hazardous location, the following actions should be taken:

  • Signing and flashing rotating yellow light should be carried out in accordance with Figure 2 (See also Sections 3.4 and 3.5),
  • Any person standing on or adjacent to the road for the purposes of controlling stock should wear clothing with reflective strips,
  • Floodlighting shall be provided at the crossing point. The lighting should be sufficient to clearly illuminate stock on the road formation in the vicinity of the crossing point. If the road reserve is wider than 30m then floodlights should be placed on both sides of the road reserve, and
  • The Main Roads sign STOCK AHEAD PREPARE TO STOP (MR-WAW-6) should be considered for use.
  • With reference to Figure 1, the STOCK AHEAD PREPARE TO STOP sign should be positioned in place of the STOCK AHEAD sign.

1.3 Droving of Stock Along a Road

Where it is necessary to move stock more than 100m along a road reserve, signs should be erected along the road shoulder in accordance with Figure 3. In addition, a lead vehicle and a tail vehicle should be placed in front and at the rear of the stock to warn approaching motorists. The vehicles should be located at a distance from the stock as shown in Table 2.


FIGURE 3 - Signing for droving of stock

Note: When using the NEXT ... km sign, the value for the distance should be between 1km and 10km.

Where stock can be moved along the road reserve without stock or vehicles travelling on the carriageway, it remains necessary to adhere to the signage shown in Figure 3.

1.4 Signs

The conditions of the following publications have been described in this guideline:

  • Main Roads Signs Index and relevant guidelines,
  • Occupational Safety and Health Regulations 1996 Act, and
  • Relevant Australian Standards.

Therefore, this guideline provides sufficient guidance for a person wanting to take stock onto a road to comply with the necessary standards. If required, further information can be obtained by contacting the Regional Manager for Rural Regions or the Manager Traffic & Safety for the Perth Metropolitan Area.

Signs should be erected in accordance with these guidelines and Main Roads Standard Drawings 9548-0106 and  8720-0762. All signs shall be rigid. The class of retroreflective material used shall be Class 1. Refer to Sign Standards for more information.

Signing should be displayed prior to and during the stock movement. Signs and flashing yellow warning lights should be positioned and erected so that:

  • they are properly displayed and firmly secured so as to prevent them being blown over by the wind or passing traffic, and
  • signs may be placed on the roadside or road shoulder and should be at least 1m clear of the road lanes.

The signs and any flashing yellow lights should be displayed or installed immediately prior to the stock being driven on to the road reserve and folded over or removed as soon as the stock are no longer in the road reserve, as per Section 3.1.

Signs are a specified treatment in this guideline, and typical signs are listed in Table 4.

1.5 Vehicle Mounted Warning Device

The flashing yellow warning light shall comply with the equipment described in the Road Traffic (Vehicle Standards) Regulations 2002 . Vehicle indicator lights do not constitute a flashing yellow warning light.

1.6 Stock Underpasses

Stock underpasses generally consist of reinforced concrete box culverts of a size suitable to allow safe passage of the stock and the farmer.  Sizes for these structures may, for example, be:

  • 1200 x 1200 mm Sheep movements,
  • 1500 x 1500 mm Sheep movements where the stock owner may access the underpass, or
  • 1800 x 1800 mm Cattle movements and where the stock owner may utilise a vehicle in the underpass.

Fencing details for the underpass to prevent stock from entering the road is available in the Guide to the Design of Fencing & Walls.
