Well JJ nothing comes up on my machine when I do that! Anyhow for the benefit of Terry and Jan if they are having the same problem, just ignore them, ( toll roads that is) they only fine the locals and don't bother with UK registered and plated vehicles, honest, just been, no probs.
I of course should add that I don't know about "every" toll road in Portugal but Its up to you, the official advice used to be wait until we write to you at your home address, they never did, if your worried the official Portugal Toll website is HERE
Electronic toll roads, correcto Mundo dear chap, old toll roads and booths not so, that's kind of why I put down the official web site, mind you I did say, I haven't been charged, which remains correct, looking forward to seeing you soon.
As MikeD says above, if entering on a motorway look for a lane going off marked Tourists or something like that. There should be a stop line by a machine, make sure you drive right up to the stop line so the camera can read your number plate. I didn't and couldn't understand why the machine wasn't playing.
I didn't think the tolls were cheap but it may vary across the country. I went from one end of the Algarve to the other and then back gain and the cost mounted up. They do helpfully tell you in advance of each section what it is going to cost you.
Of course there is then the whole issue of whether, if and when they ever take the money from your card!
But Portugal is a nice country so best to play by their rules. They were on our side in the Peninsula War when those damned French invaded them. These things should not be forgotten.
When you register for automated payments you get a ticket with your registration that confirms your vehicle is registered (lasts for a year). I've been told that IF you get stopped by the police you're supposed to be able to produce this ticket - probably just another excuse to "fine" tourists.
It is actually quite easy to avoid motorways completely with a little checking of a, dare I say it, ................................. MAP.
This is hearsay......but I have heard ( hearsay) that if the opposition get in at the next election, they are going to put up barriers at each entrance and exit. This is because, apparently not many drivers are paying and they have worked out that the barriers will pay for themselves in no time at all. Still that will be a couple of years away.......if ever.
