Hi All - First time I am taking my car over to France. We are going by ferry from Dover to Calais - I am trying to find out what the process is from when you arrive at dover to when you hit the motorway at calais. What documentation is required/checked that I need to prepare or produce? All the other stuff is fairly clear - with the exception of the breathalyser situation which seems unclear but I've bought 2 anyway. Thanks in advance for any info you all provide!
