An English language website, Sanef Tolling, has been opened enabling people to register for one of the small transponders that is attached to your windscreen.
Users of the service are asked to set up a Direct Debit, pay a small returnable deposit for the transponder, a yearly fee and an initial administration charge.
The total upfront fee is €39.14, including TVA, of which €20 is refundable. There is also a rental fee, which will not exceed €10 plus TVA, a year.
Then after receiving confirmation of the opening of your account and the transponder, you are able to travel on all the autoroutes across France, and use the special Liber-t lanes at toll booths.
As you approach the barrier at the booth sensors register your transponder, raising it and calculate the fee payable, this is then deducted automatically from your account via the Direct Debit arrangement.
Owners of caravans and motor homes can also register for the card, although they have to use a different toll booth, found to the right hand side of the line of booths.
