Road markings are regulated in terms of the SA legislation. The National Road Traffic Regulations allow for the zebra crossing type and the marking that simply consists of 2 white lines across the road.
The lines are used at intersections and the zebra crossing in mid-block crossings. The paint must be white and not be red.
No other markings may be in the marking. Section 57 of the NRTA prohibits other than the markings prescribed markings to be painted.
