Portugal on a Dutch Licence — No IDP, But the Tolls Are a Trap

Portugal is about as easy as it gets for a Dutch visitor: your EU licence is valid with no IDP, you stay on the right, the alcohol rule matches home at 0.05, and the motorways are relaxed and well surfaced. The one thing that genuinely catches Dutch drivers is not a rule of the road at all — it is how you pay for it.

Portugal runs an electronic-only toll system on parts of its motorway network, and this is where hire cars come unstuck. On certain routes — many of the newer motorways and the A22 along the Algarve — there are no toll booths and no cash option at all. Cameras read your number plate, and the charge is later billed to the car’s registered keeper, meaning your rental company, who then passes it on with an administration fee. The fix is to arrange this before you drive off: ask the desk to fit the car with a transponder or to register a card against the plate. Skip that step and a string of small tolls turns into a frustrating post-trip invoice. Our Portugal driving guide sets out which roads use the electronic-only system.

Beyond the tolls, the driving is straightforward. Speeds are 50 km/h in town, 90 on rural roads and 120 on the motorways — a touch faster than the 100 km/h you are used to in the Netherlands, so the open-road sections feel quicker. Enforcement is a mix of fixed cameras and patrols, and a speeding penalty can range widely from €60 to €300 depending on severity; you can gauge yours with the speeding fine calculator.

The car should carry a warning triangle and reflective vest, both of which Portuguese rentals provide. On alcohol, the 0.05 limit mirrors the Netherlands, but summer enforcement on the coast is heavy, so keep to none before driving. If any toll or speeding charge does follow you home, our guide to who pays driving fines abroad explains how rentals handle it. The emergency number is 112.
