Umm yeah, not 100% sure but like on highways where the speed limit is 100km and 110km etc, P platers are only allowed to go to 90km.
Oh and btw adels rules and brissie are a bit different (my bad for saying they the same). We can get our L's at 16 and after 6 months we can get our P's, therefore you can be on your P's at 16.5 in adel.Plus we dont have any restrictions of cars that P platers can drive, e.g you can be on your P's driving turbos, and V8s etc.
