Are you confused about driving licences in Spain, and whether you´re legal or not? Well according to advise given by Linea Directa in a recent "Insider Tips" in the Sur in English - the following is correct.
Driving licences issued in any EU country or European Economic Zone, such as Norway and Ireland, are indeed valid. All other licences are only valid for a maximum of 6 months, with renewals being obtained from the Provincial Traffic Headquarters before they expire.
For those of us with EU licences, they are valid providing you complete and pass a psycho physical medical test, as per Spanish law. The current requirement is every 10 years until the age of 65, and then every 5 years after that. These conditions apply to anyone who is a resident in Spain with valid residency paperwork. If you fail the exam then the licence is no longer valid
The exam is made up of four tests and takes around 20 minutes to complete. There is a psycho physical evaluation which checks reaction times and hand to eye co-ordination using a computer simulator. There are then eyesight and hearing tests, and a general medical check-up looking at such things as blood pressure and cholesterol levels.
For a full list of the official medical centres used specifically for the renewal of driving licences then go to the Direccion General de Trafico website
