Yes, but in SA this only applies if marked as depicted.
If you have a multi lane traffic circle without explicit markings, you have to treat the lanes just as you would normal lanes on a straight road - i.e. if you want to move from the inner lane to the outer lane to take the exit, it is treated as a lane change and you don't have automatic right of way. This means that in South Africa, unlike most other countries, in a two lane traffic circle with no explicit markings you are within your rights to go all the way around in the outer lane (unless mandatory exit arrow is marked). I know, it's stupid, but that's how it works here.
