There seems to be confusion over electronic tolls in Portugal. Thought I would update you on our experience. We decided to.not bother with them and set sat nav to non toll. However we still ended up on one yesterday and judging by the few display boards we passed we reckon we owed them about€6 and no way of paying. Not wanting to be fined we thought we would try and register our vehicle.We asked around last night a friendly local told us to go to post office in Leira. Found that and were redirected to ctt in the town. Found that....queued for 20 mins to be told we only deal with portugese cars not English. Asked where to go and she said "just drive and they will send you a bill to your house....maybe!" So will continue to avoid tolls anyway but we know if we inadvertently end up on one we have done our best to try and pay our dues!
