Although driving in France is very similar to the UK, apart from the obvious of driving on the other side of the road, there are certain differences in regard to what you have to carry in the car.
I have attached a short list of the minimum requirements.
A couple of other points to note when driving in France, although not so widely used now but still the law is the priority from the right ( priorité à droite ) this is only generally in towns and villages but does mean that traffic coming out of a side road, unless otherwise marked does have priority so beware!
The drink driving laws are also a lot stricter than the UK the legal limit is 0.5mg/ml of alcohol per litre as against 0.8 in the UK
0.5 and 0.8mg of alcohol in your blood you could be fined between €135 to €750.
