A few months ago we announced that France was going back to having road tax disks
on windshields, similar to system used in the UK. However, the process has been simplified quite a bit from the French Minister of Economy's original idea. Plans to complicate the fee by basing it on Euro pollution levels is gone. Instead, France will tax cars that produce over 250 g/km of CO2
an additional €160 per year duty. That's simple enough, isn't it?
This measure only applies to cars purchased after January 2009, so it won't affect families with older vehicles. France also announced that the disk will be on sale at tobacconists (a place where you can buy legal paper and stamps), because the original idea was to make the disk available with your insurance
papers, something insurers were not happy with.
