  2. If you are not enrolled in a driver course, you can obtain an examination permit at least at 17 years old. After six months of supervising driving, you can get a probationary license. After one year of unsupervised driving, you can get a basic driver license at 18.
  3. If you are 21 years old, after obtaining the permit and three months of supervising driving, you can get a probationary license. After one year of unsupervised driving, you can get a basic driver license.
