4Periods of darkness#

“Periods of darkness” refers to any period where daylight is inadequate such that visibility is adversely affected. This includes night time, dusk or dawn, and in times of inclement weather when there is poor visibility. Typically a motorist would use the headlights of their vehicle to assist their vision and/or recognition in such periods.

When a traffic controller is working in periods/shifts that run between daylight and darkness periods, the garment worn by the traffic controller must be an appropriate garment for periods of darkness.
