In researching our Turkey trip we read several times that you will get a big fine for driving on the toll roads without a toll card. This caused us to turn around at Izmir when the toll gate caught us by surprised without a card. It's a load of rubbish by misinformed people. You enter the toll road, drive to your destination and buy a toll card from the PTT office just before the exit toll booths. Takes 5 mins and costs 35 TL. A lot of worry for nothing.
