Portugal's tolls: the electronic-only trap and the official ways to pay

Several Portuguese motorways carry exclusively electronic toll collection — the official leaflet's EasyToll section is explicit that the system is valid only on highways with exclusively electronic tolls. There is no booth to stop at: gantries read the plate, and an unregistered foreign plate becomes an unpaid toll. The fix is pre-registration, and the official options below are the ones the infrastructure operator itself publishes.

Per the leaflet: EasyToll associates your bank card with the vehicle's number plate (Visa, Mastercard and Maestro), runs on automatic debit, and is valid for 30 days. Cost: €0.74 enrolment plus an administrative fee of €0.32 per trip. Sign-up points sit at the entry corridors — the A28 Viana do Castelo service area, the A24 near the Chaves/Verín border, the A25 Alto de Leomil service area, and the A22 by the Castro Marim/Ayamonte border — and the leaflet's warning deserves bold: the membership receipt must be kept.

The post-office alternatives, per the same leaflet: the 3-day card — unlimited use for three days, €20 plus €0.74 enrolment, vehicle classes 1 and 2 only — and the multi-journey card for predefined routes (the Porto and Faro airport connections), priced at the route cost plus €0.74; both sold online at ctt.pt, in CTT stores and at marked service stations. Renting? Ask the rental desk what the car already carries — many Portuguese rentals include a Via Verde transponder with its own billing terms, which is a contract question for the rental-rights checklist, not a toll question.
