Does InterRent require an IDP in Portugal?

InterRent in Portugal: the policy in plain terms
Asks for a licence translation for non-EU and non-Roman-alphabet licences across its European locations. Europcar's value brand for leisure travellers in Europe.
Non-EU visitors should carry an IDP to drive and rent in Portugal.
In Portugal specifically, many rental companies and local authorities in Portugal ask foreign drivers to present a translation of their licence alongside the original, so InterRent will typically ask for it at the counter. Requested for licences issued outside the EU/EEA.
InterRent runs a europe network; at its Portugal desks, foreign renters are asked for an International Driving Permit in the 1949 Geneva and 1968 Vienna Convention format alongside the original licence. Portugal drives on the right, uses the EUR, and sets a minimum driving age of 18, so an IDP is the document that removes any doubt at the counter.
What to bring to the InterRent counter in Portugal
- Your original national driving licence (the IDP never replaces it).
- Your International Driving Permit in the 1949 Geneva and 1968 Vienna Convention format.
- Your passport and a payment card in the main driver's name.
- Local payment for the EUR deposit; Portugal drives on the right with a young-driver surcharge under 25.
Driving rules in Portugal InterRent renters should know
- Electronic tolls (Via Verde) — arrange with your rental car.
- Reflective vest and triangle required.
- 0.05% alcohol limit; 0.02% for new drivers.
- Dipped headlights in tunnels.
InterRent's rental terms that affect your IDP booking
InterRent's minimum rental age is typically 19-21 depending on country (19 in Spain, 21 in the UK and France), and drivers aged roughly 21-24 (24 and under in some markets) pay a young-driver surcharge that varies by location, for example around 8.50 EUR/day (max ~93 EUR) in Spain, 12.95 EUR/day (max ~181 EUR) in France, and about 35 GBP/day (max ~350 GBP) in the UK; some vehicle categories require drivers to be over 25.
A refundable security deposit is pre-authorised (held, not debited) on the main driver's credit card at pick-up; the card (Visa or Mastercard, sometimes Amex) must be in the main driver's name with an expiry date after the return date, and debit cards are not accepted because their rules do not fit InterRent's deposit policy.
Additional drivers must present their own valid driving licence at the counter and sign the rental agreement at pick-up; InterRent charges an extra-driver fee per day that varies by location, though it is frequently included in promotional/package rates. The main driver must have held a full, valid driving licence for a minimum of 12 months (one year) prior to picking up the vehicle.
Cross-border travel and one-way rentals are restricted and must be authorised in advance; cross-border fees and one-way drop-off charges apply and vary by route, with certain countries (typically higher-risk or non-EU destinations) excluded entirely under the rental conditions.
InterRent requires a full, valid driving licence held for at least 12 months; for licences not written in the Latin/Roman alphabet (or otherwise not understandable to the rental agent), an International Driving Permit (IDP) must be presented alongside the original national licence, as the IDP is a translation and never replaces the physical licence.
Once you collect the keys in Portugal
Portugal mixes staffed toll plazas with fully electronic 'ex-SCUT' motorways that have no booths and read your plate via Via Verde. Rental cars carry a Via Verde transponder (about EUR 1-2/day plus tolls billed to your card); independent drivers can use EASYToll, registering a card to the plate at a border/airport kiosk for EUR 1 setup plus per-transit charges.
In Lisbon paid zones are run by EMEL (pay by machine or app), and Porto and other cities have similar metered zones; bays are scarce and illegal-parking fines reach about EUR 300. Peripheral park-and-ride plus public transport into the centre is the practical option.
Speeding fines start around EUR 60 and rise sharply, and police can demand on-the-spot payment from non-residents (a deposit) for offences such as speeding, phone use or no seatbelt before allowing you to continue. Camera fines to foreign drivers are passed on by rental firms with an admin fee.
Call 112 for emergencies (the GNR or PSP handle road policing). For a minor crash, complete the European Accident Statement (Declaracao Amigavel) jointly with the other driver; call police if there is injury, a dispute, or a driver without documents, and do not move vehicles before documenting an injury crash.
