Does InterRent require an IDP in Liechtenstein?
Written by Daniel MercerUpdated July 2026
InterRent in Liechtenstein: 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.
This Alpine principality drives on the right and shares Switzerland's strict rules; non-EU visitors should carry an IDP, and a Swiss motorway vignette applies on through routes.
In Liechtenstein specifically, many rental companies and local authorities in Liechtenstein ask foreign drivers to present a translation of their licence alongside the original, so InterRent will typically ask for it at the counter. Cars are usually rented in Switzerland or Austria; an IDP helps non-EU drivers.
InterRent runs a europe network; at its Liechtenstein desks, foreign renters are asked for an International Driving Permit in the 1949 Geneva and 1968 Vienna Convention format alongside the original licence. Liechtenstein drives on the right, uses the CHF, 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 Liechtenstein
- 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 CHF deposit; Liechtenstein drives on the right with a young-driver surcharge under 25.

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 Liechtenstein
Liechtenstein has no toll roads or vignette of its own, so driving inside the country is free; however you almost always arrive via Switzerland (CHF 40 annual motorway vignette) or Austria (digital vignette), so check your rental already carries the relevant sticker.
Vaduz parking is colour-coded: white zones are paid pay-and-display (or free where marked), and blue/red zones allow limited free parking only with a parking disc obtainable from police stations, banks and tourist offices.
Speed and traffic enforcement mirrors Switzerland and is strict: fines rise steeply with speed and exceeding the urban limit by 26 km/h (or 31 km/h outside towns) after tolerance triggers licence withdrawal. Camera fines are forwarded to the renter by the rental company.
Dial 112 (or police 117, ambulance 144) for any injury accident; for minor damage-only cases exchange details on a European Accident Statement and notify the rental firm, and do not move vehicles after an injury crash until police attend.
