Yes, Kevin, for 12 years, however, things seemed to have been tightened up now, the law is, copies are not accepted. Perhaps the law may be have been bent, in the past. but I have also read of people being fined 400TL for not carrying a passport. One guy on T.A was taken to the Police Station.
We also only ever carried copies of our passports in the past. However, will carry passports from now on.
