A general speed limit is applicable on all roads and does not have to be displayed by a road traffic sign.
Unless otherwise indicated by a road traffic sign, a speed limit of—
60 kilometres per hour shall apply in respect of every public road situated
within an urban area;
100 kilometres per hour shall apply in respect of every public road other than a freeway, situated outside an urban area; and
120 kilometres per hour shall apply in respect of every freeway.
Exceeding the speed limit is an offence.
