It's not clear, it says on the France.Fr website that In Paris, the sticker is compulsory within the perimeter of the A86 motorway from Monday to Friday, from 8am to 8pm, except on public holidays.
I need to drive on the A86 from Vaucresson to join the A6 at Fresnes. Do I need a sticker and if so, how the hell do I get one within a week?
