Motorway M1, Hungary, 2015/12.
My first and for a while only photo in the Iran gallery!
Sorry for the quality! Spotting was made difficult by a thick fog. We passed 2 Iranian trucks with trailers on the way, but I only managed to get this photo, and a barely visible shot of one of the trucks. (Will be posted in the comments) Unfortunately I haven't seen anything from Iran since then, though I missed a bus in Budapest, earlier in 2015.
