Toll Roads in Portugal: How to Pay With a Rental Car

Driving in Portugal is straightforward, but the toll system trips up many travellers because not all tolled motorways look the same. Some have traditional toll booths where you stop and pay. Others have no booths at all — just overhead gantries that read a transponder or number plate. If you drive through one of those without the right setup, you will get a fine.

With a rental car, this is simpler than it sounds — but only if you ask the right questions at pickup.

Two types of toll road

Motorways with toll booths: you take a ticket at entry and pay at the exit barrier by card or cash, just like most European toll roads. No special equipment needed.

Electronic-only motorways (without barriers): there is no place to stop and pay. Overhead gantries read the vehicle transponder as you pass through. If your car has an active Via Verde transponder, the toll is recorded automatically. If not, the cameras photograph your number plate — and if it is not linked to a payment method, a fine follows.

The electronic-only motorways are the ones that cause problems. The road looks like a free motorway right up until you see the gantry. By then you have already passed through.

Via Verde: how it works with a rental car

Via Verde is Portugal’s electronic toll system. Most major rental companies fit their fleet with a Via Verde transponder. When you drive through a gantry, the system reads the transponder and records the toll.

At the end of the rental, the supplier charges the accumulated tolls to your card, plus a service charge. This charge varies by supplier — it may be a flat daily fee (typically 1–3 euros per day) or a per-trip fee. Some suppliers include toll charges transparently; others add a processing markup.

At pickup, ask two questions:

1. Is there a Via Verde transponder in this car, and is it active?
2. How are tolls billed — per trip or per day — and what is the service charge?

Those two answers prevent the most common surprises on the final invoice.

If your rental car has no transponder

Some local suppliers or older rental fleets may not have a Via Verde device fitted, or it may not be active. In that case you have two options:

Via Verde Visitor: a transponder for tourists, valid for 90 days and linked to your payment card. Available online, at motorway service stations, post offices and Via Verde sales points. It is the cleanest solution for electronic toll roads if the rental car does not have one.

Toll-free route: set your GPS to avoid toll roads. You drive on national roads — slower and sometimes more interesting. For a day trip or short journey around a city this works well. For the Lisbon–Porto route or a cross-country drive it adds considerable time.

Do not assume you can sort it out on the road. Electronic toll roads have no booths and no way to pay on the spot.

A22 and other motorways: what changed in 2025

An important update for travellers: since 1 January 2025, the A22 (Via do Infante) in the Algarve is completely toll-free. This covers the full route between the Spanish border near Ayamonte and Faro. Drivers between Lagos, Albufeira, Faro Airport and the border no longer need to worry about tolls on this road.

Several inland motorways that previously charged electronic tolls have also become free: A23, A24 and A25 are now toll-free.

The main motorways between cities — including the A1 (Lisbon–Porto) and A2 (Lisbon–Algarve) — remain tolled.

Typical toll costs

Costs vary by distance and vehicle class. For reference:

• Lisbon to Porto (A1, ~310 km): approximately 22–26 euros
• Lisbon to Faro (A2, ~275 km): approximately 18–22 euros
• Lisbon bridges (Vasco da Gama, 25 de Abril): 1.50–3.00 euros depending on direction and vehicle

These amounts are the road tolls. The rental company service charge is added on top.

Common mistakes

Thinking no barrier means no toll. The most common error. The absence of a booth means electronic charging, not free passage.

Refusing the Via Verde service without checking your route. If you plan to drive on the A1, A2, A8 or A9, you will encounter gantries. Opting out of the transponder service without knowing your route can lead to unpaid tolls and fines.

Following GPS without understanding what it routes. Some navigation apps default to the fastest route, which usually uses tolled motorways. Check the route options before you set off and choose deliberately.

Assuming the fine will not arrive. Portugal’s toll enforcement system will identify a foreign-registered car via the number plate and track down the registered address of the rental company. The charge — plus a significant administration fee — will come back to you from the supplier, sometimes weeks after the trip.

Comparing rental cars for Portugal

Compare car rental offers in Portugal and check how each supplier handles tolls before booking. Some include the Via Verde service transparently; others charge more per day. Knowing the toll arrangement before you travel is part of understanding the real cost of the rental.

In short

Portugal’s toll system works well with a rental car as long as the Via Verde transponder is active. Ask at pickup, note the service charge and keep the invoice after return. If your car has no transponder, get a Via Verde Visitor before you use electronic motorways — not after. And if you are heading to the Algarve, the A22 is now free, which removes the biggest source of toll confusion for visitors to that region.
