“Penalty points driving licence” what is it?

​From the 1st of June, 2016 on a total of 12 (twelve) points will be given to each driver in its driving licence.

For each major or very serious offence or road traffic crime, points will be subtracted to your licence. 
If you do not commit major or very serious offences or road traffic crimes, points can be added to your licence.
If you commit a major or very serious offence, besides the fine and to be, eventually, temporally disqualified from driving, you will also lose points.
