Overall, you need to have a good vision to be able to drive, if not, your candidature is immediately rejected. If you don’t fail at any point, you need to take six steps, otherwise, you might need more. There is two major tests, the theorical task and the practical test.
You need first to visit a driving center and complete the application paper. If you pass the eye test correctly, it is time to pay the fees and to take the written test. At each test, there is two possibilities. If you pass the theorical exam, you can do the driving test, otherwise, you will need to retake the written test after your failure. You can either pass the practical test and receive finally your drivers license or fail, and you will need to retake the exam to get your license.
