ey Paladin, (Thanks for welcome
well how it works is that you first acquire a learners license (same counts for different types of vehicles) by writing a test on the theory of the road and a small section on the vehicle you intend to ride/drive. This is then valid for 18 months. (You can have a look at http://www.salearners.co.za
if you are interested
Any time inside that 18 months you can schedule an appointment for you actual license test, which in the case of a bike license involves you on your bike performing several things that shows the traffic officer conducting the test that you can handle a bike. Things like sudden evasive action, speed control, balance and traffic awareness etc.
So if you have been on the road illegally for some time on your bike you could theoretically do both the learners and "passing out" test on the same day... would be a bit suspect though
There is also different license types for bikes, <125cc and >125cc, typically school kids are limited to a <125cc license.
Problem is that there are huge backlogs country wide, not all traffic departments perform the tests, at the moment the shortest wait for a learners appointment is about 2 months and for the actual full license test 9 months. Pretty ridiculous. Add to that the fact that they adopted a new country wide traffic system last year (called eNatis) which turned out to be very unstable initially and the problem just worsened.
At least my learner's appointment is approaching, until then I'll just have to settle with taking my buddie's Dakar for a spin in the parking lot
