Another good tip if you have the time, is to take a trip to france in your car…this will give you some idea of what to expect…then when you return you would have at least experienced of driving on the wrong side of the road…dont forget that if going through Belgium in a truck, there is a toll to pay…same as a few other countries,Germany, Eastern Bloc, Austria, Hungary etc, France is a pay as you go o0n the autoroutes ( motorway) and also Spain…but this info and where to buy the toll box, or vignette you can ask in the port or on the train amongst other drivers…dont forget to tell them you are a first time driver abroad, and most will be happy to advise…or ask on here…good luck in your quest…
