Hi, I think 'provisional licence/license' must mean something different in the nation you're in?
In the UK, once you're 16 years and nine months old, this is the earliest you can apply for our provisional licence, which is just a green permit to learn to drive. In the UK, there is no obligation to have a minimum formal hours of instruction, like some nations do. You can either get driving lessons and/or be taught by someone who is over 21, has insurance for themselves and you the learner driver and has had a full UK licence for 3 years or more.
You have to pass a theory test on a computer before you take your practical test. The theory test is a multiple choice test of Highway Code (driving and road laws) plus a Hazard Perception Test, which is a simulator of driving to test your reactions to potential road hazards that you as the driver might need to deal with/compensate for. The latter is just a series of simulated CGI clips and you have to click on the computer to show you've detected the hazard.
After passing both parts of the Theory Test, you can then take a Practical Test. This is a 45 minute drive with a driving examiner in which there is a period of following a route while the examiner inspects your driving skills and awareness and reaction to hazards, then there are things such as parking and other car maneuvres.
After passing a Practical Test, you get a pink licence and you can drive unsupervised.
