New rules now. Have to show a passport, which is photographed to send to the Police. If you are hiring from the Airport, Passport has to be photographed and set to the Hirers Office, who then have to send it to the Police, no mater what time of day. So, someone at the airport, has to have someone in the office at times of hiring to send details to police. At the moment, cannot be sent directly.
If you hire from Calis/Fethiye etc., photograph of passport is taken with the hire agreement and then sent to Police. No one is taking any chances, possible a good idea, to stop terrorists hiring cars.
