I'm off on holiday to Portugal soon and will be hiring a car. We'll be collecting the car at Faro airport and will be driving along the A22 motorway all the way to Lagos (in Portugal, not Nigeria!!). Along this route they have an electronic tolling system, and when your car's plate is picked up passing through the toll it triggers a charge. Now this charge can only be paid at a post office 48 hours after the journey. This isn't a problem when I pass the toll at the beginning of the holiday, but at the end of the holiday on the way back to the airport/drop off it's going to be impossible to pay because of the 48 hours you need to wait. Been reading that the Portuguese government send you a letter (to your home address, as supplied by the hire company) requesting payment of the toll plus anything up to a couple of hundred euros for not paying in the first place. I'm not really worried about being in debt to them, but I don't want it to affect any car hiring I might do in the future. Anybody travelled in Portugal (the Algarve in particular) and not paid the toll?? What was the outcome??
