For those putting off the evil day, I would like to say I have had a very pleasant experience applying for a Turkish driving licence - painless other than the necessary costs and charmingly helped by Ilknur as recommended here.
Having got all the necessary documents at hand - passport, driving licence, ikamet, tax number, turkish 999 number, health report with blood group listed, 6 photographs it was a 5 stop job.
Emniyet Mudurlugu for fingerprinting - from now on not allowed here
Vergi Dairesi for paying for the privellege - 338 TL
Adliye for criminal record ?5TL
Translation and Notarlisation of old driving licence plus copious photocopies 88TL
Traffic Police fro 2 more forms incl Dilekce and licence 101TL
Time taken 0900 to 1200 and hopefully pick it up on Monday
