SINGLE CARRIAGEWAY ROADS
HIGH INTENSITY WARNING LIGHTS
For a single two-lane carriageway during the hours of darkness with the loss of one lane, or part of a lane:
- high intensity warning lights are not required where there are "STOP/GO” signs or temporary signals, but are required for priority signs during the hours of darkness where there is a loss of one lane or part of a lane;
- a high intensity warning light should be placed at the location between the end of the lead taper coning and the start of the parallel coning. It should be placed at the end of the "lane closed" barrier to diagram 7105 next to the "keep left/right” sign to diagram 610 facing the oncoming traffic; and
- if the remaining single carriageway is 5.5m or less, then a high intensity warning light should be placed at the location between end of the parallel coning and the start of the exit taper coning. It should be placed above the coning facing the opposing oncoming traffic.
