This is the official information page from the the government, again in French, but I am working on it
Let me know what Category you come under then I can direct you to the lower pages, to see if you need a permit, ■■■■■■ and of any restrictions there may be.
One I can tell you about is that you cannot drive the CE between midday Saturday (or day before a bank holiday) right up to 6am Monday (or day after the holiday).
Also CE’s usually use Nationals not the motorway system, unless authorised to do so.
