Very helpful, thanks.
We however are stuck at Cesme customs, where they have stopped issuing insurance on entry. Does anyone have a contact in Turkey to organise UK registered motorcycle insurance? Many thanks

There are lots of insurance shops with signage "Sigorta" in every Turkish town. I can see that there are several in Cesme Town, approx a 20min walk from the port. If it were me, I would ask Customs if you can leave your bike in no-mans land for an hour, then walk or taxi into town to one of the shops. They should be able to help you. You'll need your passport and V5. Good luck!

Thank you. We finally managed to get insurance via a port employee as intermediary. We paid a few Euros extra but we are through. We also had fun trying to leave the port as ‘computer said no’ a few times between border police, customs and yet another lot of officials. All good as all part of the adventure. Thanks for your help.

Last september I crossed from Bulgary into Turkey. I went through the Malko Tarnovo border crossing, and truth is that nobody asked me for my insurance or green card. I had a green card issued by my insurance company in Andorra, but they forgot to ask me and let me through after checking only my passport. They were way more interested in whether I had a drone or not, and they even searched my panniers for one (I don't carry a drone with me).

Another thread bounce, proves I've done a search anyway ;)

Will be crossing Kos-Bodrum in spring. Does anybody know if I can get insurance at the port, or if there is some way to do it online in advance? UK registered bike. Yes I know I can ride in overland but that's not what I want to do. Thanks!
