Don't forget that French licences do not include the caravan/towing option (up to 7 tonnes on an ordinary UK licence I think). When they saw mine they asked if I wanted that option on my French one when I said yes, I then had to go through a medical which I am now obliged to go to every 5yrs. I had a normal UK licence, I now have a French licence B,E (b), most French licence holders will just have a B on passing their test. YF&S
