Needed to change my current driving licence for a Spanish one last week. Original licence out of date since January last and thought this would be a problem. No such thing for the Traffico Man in Tarragona! Took one look at my licence, saw that it was out of date and just shrugged and said 'no problem'! I then gave him the following which he photocopied: DNI card,  Passport and driving licence. He returned all to me there and then. I also gave him two recent passport style photographs of myself. He explained that he would contact my country to verify the validity of my driving licence and would contact me by telephone when they were ready to issue me with a Spanish one. Could take up to three months depending on how fast it is processed in my country. I will then return to Tarffico in Tarragona, having taken a small reaction test in Tortosa, pay my €26+. They will issue me with a temporary licence and will post the proper one within a  month. Easy and job  done! Hope this helps anyone who should be doing the same. Is is illegal  to drive here on another country's driving licence once you have been here for 6 months. Could have insurance implications in the event of a claim, I am told.
