Iran transit document
I entered Iran a few days ago with my 4x4 (with a Carnet de Passage and a 26 day Tourist visa), and was given a document basically stating I had 7 days to follow a fixed route from the Turkmenistan border to that with Pakistan. I told the guy that I was planning to stay far longer, and he said "no problem". I have bought insurance for two months, and plan to stay this long. No police, save for those as i left the border, have asked for the document, though I've only driven about 300km.
From other travellers with cars in Iran I get the impression they give you loads of documents at the border, but they can be ignored (most people don't bother getting the transit plates, I was not even asked to do this).
Can anyone reassure me that I will not be asked for this document by police (I think I am going to lose it)
