HELP!
We used it in 2010 but haven't been back to France since. It's one where you only pay when you use it (& thinking about it, the credit card it was registered to will have expired)
Also the car it was fixed in is long gone & we don't have the sticker to go behind the mirror - would just holding it up work?
I get emails from APRR occasionally but they're all in French 
We're going on Friday so too late to start again...I don't want to get stuck in the telepeage line first time of trying & hold people up!
