I think you can drive in any EU nation on your UK license, thats why there are 12 stars on your photocard and it is also in French etc…
the only difference I can think of are that French people drive on the other side of the road (a basic diffrence but easy to forget whilst tired which is why a lot of foreign drivers prang when over here)
there is also a “diamond” thing on road signs for priority (which Britain doesn’t have) and its worth checking what this means. Contrary to popular misconception the French aren’t that much worse drivers than in Britain (well the ones I knew weren’t) and do have some sense of self-preservation..
if you don’t feel 100% confident though then don’t risk it. Bear in mind also a UK registered car full of young people sticks out like a sore thumb when it comes to cops and roadside checks, and although penalties for drugs, motoring offences etc are no harsher than in England, if caught you may get euro-bailed and have to return to the country at your own expense or even risk being breached by UK cops, and have to serve custody in two countries!
