well in australia when you turn 16 you do a test then you can drive with a fully licenced driver in the passenger seat for 1 year, during that time you have to have a "L plate" on your car. then you go for a driving test then you can drive around alone with 'red p plates' for 1 year and you are speed limmited to 90 kmh (55mph). then you do another test and the can drive alone with "green p plates" and you are speed limmited to 100kmh(60mph)
for 2 years, then you do another test and you have your full licence :)
