It is very easy to get a driving licence.
Just go to the driving licence office........................just in front there is a place clearly signed for medicals and you go in and they give you a test for all of five minutes.............make sure that you can walk, have arms and legs and can see. They give you a medical certificate and you take this into the office along with your current driving licence.
There is usually a line up...............but if you are over 65 and look it....you explain to the guard in charge of the line and they send you right to the front where there is a special section for over 65"s.
The whole process should not take much more than a couple of hours.
