Slicker as to the fine I don´t know but the driving ban laws in both countries are two different kettles of fish.
France it is a general ban on all roads with exceptions for certain types of freight i.e. perishables
In Germany you have two types of ban the general one for Sundays and Bank holidays where driving is prohibited on all types of roads and the partial one for Saturadays in the holiday season where certain stretches of motorway and Bundesstrasse have a ban and others do not.
