Road Narrows Both Sides Sign Face Diagram 516 (face only)

This quick fit road narrows both sign face should be used to give warning that the current section of road is going to reduce in width. This specific sign under diagram 516 is generally used where the road is obstructed on both sides of the road somewhat equally. It is almost always used with a supplementary plate stating “Single file traffic”.

This warns drivers that they may need to give way to oncoming traffic, or just that there is not enough room for two vehicles to pass. Alternative versions of this sign include a road narrows right, and road narrows left variations. These are used where the reduction in width of the roadway is primarily from one side, as is the case with most roadworks.

This sign should be used in accordance with the guidelines published in the Chapter 8 and Chapter 4 traffic signs manuals. Links to both of these documents can be found on our regulations page.
