The N4 is a national highway that stretches across the entire northern section of South Africa, from the Botswana border in the west, through Pretoria, to the Mozambique border in the east. Astonishingly, there are only four official passes on this road, and Magatasnek is the only one located on the western half. The pass lies just to the west of Rustenburg.
The N4 is heavily tolled, and has a reputation as a dangerous road, in particular the section between Brits and Rustenburg, where there is only a single lane in each direction for much of this route. Impatient motorists tend to overtake slow moving traffic without any regard for the road markings and signs, resulting in a number of injuries and fatalities.
