Speed limits in South Africa are set the same in each province of South Africa. Highway speed limits can range from an urban low of 60 km/h to a rural high of 120 km/h. Speed limits are typically posted in increments of 20 km/h. There are also limits for trucks and occasionally minimum speed limits.
The general speed limits are regulated in terms of the National Road Traffic Act, 1989.[1][2][3]

Speed limits
General terms
60 km/h on a public road within an urban area

National routes in South Africa numbered from N1 to N18 have a fixed speed limit of 120 km/h, with sections which are in urban areas limited to 100 km/h.
Special regulation
On a section of the N14 between Pofadder and Kakamas, authorised vehicles for speed testing are subject to 250 km/h speed limit on a 160-km-long section of road.[4][5]
Regional and provincial routes in South Africa numbered from R100 to R799 have a speed limit ranging from 60 km/h to 100 km/h, with some parts limited to 120 km/h.
Metropolitan routes in South Africa numbered "Mxy" have a speed limit ranging from 60 km/h to 100 km/h, with some parts at 120 km/h
Proposed reduction
It has been proposed that the national speed limit throughout South Africa should be reduced. This would be implemented with South Africa's new road demerit system.[6][7]
The Department of Transport proposed that the baseline top speeds across the country's roads should be reduced by 20 km/h.[8] This would effectively drop the speed limit on the country's highways from 120 km/h to 100 km/h, while the top speeds on main roads would drop from 100 km/h to 80 km/h.[9] Speeds in residential areas would decrease from 60 km/h to 40 km/h.[10][11][12]
